Brandjes: Paintings as witnesses to fires 1640-1813

It wasn’t until 14 May 1842 that wood engravings of news stories were first published, in The Illustrated London News, a weekly collection of illustrated reports of wars, accidents, fires and other news. Towards the end of that century, magazines were starting to include colour images of newsworthy events.

Enterprising painters had anticipated public demand for colour images of catastrophes like fires since the early seventeenth century, and in the Dutch Golden Age these were known as a brandje, showing a major fire, usually at night. This weekend I show a selection of these, but exclude depictions of fires that the artist clearly didn’t witness, such as the destruction of Sodom and Gomorrah, the sack of Troy, or the burning of Rome.

Among these are some of the earliest examples of what the Impressionists specialised in, depictions of the transient effects of light, often painted en plein air.

Frans de Momper’s A Fire in Antwerp was probably painted around 1640, and shows a large fire occurring at night in the centre of the major city of Antwerp. De Momper not only shows the crowds of people bringing ladders and tools to help, and the bright white light of the fire itself, but the huge pall of black smoke rising over the city.

In mid 1652, Jan Abrahamsz Beerstraaten seems to have witnessed the destruction by fire of part of the centre of Amsterdam, which formed the basis of his studio painting of The Old Town Hall of Amsterdam on Fire, 7 July 1652 (1652-55). Local inhabitants are walking in orderly queues to boats, in which they escape from the scene.

De Momper and Beerstraaten didn’t specialise in brandjes, though. Egbert van der Poel did, and probably painted more than any other artist in history. Van der Poel moved to Delft in 1650, and four years later was a victim of the massive explosion in a gunpowder store there on 12 October 1654. That killed one of his children, and he moved again to Rotterdam.

It has been thought that most of van der Poel’s Fire of a Church with Staffage and Cattle from 1658 is a carefully-composed composite of his experiences. A small church at the edge of a village is well ablaze, and the inhabitants are abandoning it, taking all the possessions they can, including their horses and livestock, and leaving the fire to burn itself out.

Van der Poel’s undated A Fire at Night shows a similar scene and composition, set this time on the bank of a canal.

One established exception to this is van der Poel’s Fire in De Rijp of 1654, completed in 1662. This shows a fire that worked its way through more than eight hundred buildings in the town of De Rijp during the night of 6 January 1654. This left only the northern section of the town standing and inhabitable, and resulted in more casualties than did the more famous explosion in Delft at the end of that year.

Doubt is cast on this received account of van der Poel’s work by sketches such as this, of The Fire in the Nieuwe Kerk, Amsterdam, in 1645, made in front of the motif using washes with touches of pen and brown ink. Perhaps he was the first ‘ambulance chaser’ who travelled out to sketch fires, from which he later painted his famous brandjes in the studio.

Adam Colonia and Philip van Leeuwen were followers of van der Poel who specialised in brandjes, although both also painted other nocturnes, or maneschijntjes (moonshines) as they were known at the time.

In 1720, the cathedral in Rennes caught fire, and burned from 22-30 December. The scene was painted in this View of Notre-Dame de Bonne Nouvelle (1720-21), shown here in a copy by Jean-François Huguet, which is claimed to be in watercolour on canvas. As with some earlier depictions of burning churches, the patron is shown watching the scene from the heavens.

In the winter of 1789, Venice’s oil depot at San Marcuola caught fire. Although Francesco Guardi was 77 at the time, he painted the scene in his Fire in the San Marcuola Oil Depot, Venice, 28 November 1789. This is one of three versions of his painting; this is believed to be a copy made between 1789-1820, and is now in the Rijksmuseum, the others being in the Alte Pinakothek, and the Gallerie dell’Accademia.

During the Napoleonic Wars, between 1803-15, civilians living in European cities were dragged into battles as their homes came under bombardment, and buildings were set alight. One example of this is the Second Battle of Copenhagen, in which the Royal Navy attacked the Danish fleet in Copenhagen harbour. This brought much of the city under bombardment, causing serious fires.

The Danish painter Christoffer Wilhelm Eckersberg was a student in the city at the time, and painted several works depicting the effects of the bombardment, including The Terrible Bombardment of Copenhagen (1807), showing the Church of Our Lady well ablaze.

In Copenhagen, the night between 4 and 5 September 1807 seen from Christianshavn (1807), Eckersberg gives a broader impression of the effects on the port area during the height of the bombardment.

When Napoleon’s army approached Moscow in the summer of 1812, most of the city’s residents fled. As the French army was entering the city on 14 September, following their success at the Battle of Borodino, on the orders of Count Rostopchin, the few remaining Muscovites set fire to some of its major buildings before fleeing. By the following day, a massive fire was burning in Kitay-gorod, at the heart of the city, and that didn’t burn itself out until 18 September.

There are many paintings showing different views of this catastrophic fire, but A. F. Smirnov’s Fire of Moscow on 15-18 September, 1812, after Napoleon takes the city (1813) is probably one of the best.

It’s thought that two-thirds of all private dwellings, most shops and warehouses, and more than a third of all churches, in the city of Moscow were destroyed by the fire over those four days, and 12,000 bodies were recovered.

A brief history of rebuilding and repairing

A cynic might summarise the history of Mac OS in four eras:

  1. rebuilding the Desktop (Classic Mac OS)
  2. repairing system permissions (Mac OS X to OS X 10.10)
  3. resetting Home permissions (OS X 10.11 to macOS 10.15)
  4. cursing privacy protection (macOS 11 onwards).

There is slight overlap between the last two, in macOS 10.14 and 10.15.

Rebuilding the Desktop

Classic Mac OS built its Desktop illusion using hidden databases that associated types of document with icons set by the apps that created them. This was based on two four-character codes in every file to specify the file’s type and creator. Periodically, those databases became damaged and this association stopped working, with the result that all documents were displayed with the same generic icon.

desktopos91

Rebuilding those Desktop databases was initiated by restarting the Mac while holding the Command and Option keys until the dialog was shown. Mac OS then checked through all installed apps to reconstruct their associations with document types.

desktopos95

This had to be repeated for each volume in turn as it was mounted by Mac OS. If there wasn’t sufficient free space on a volume, the process failed. The price of some utilities like TechTool Pro was often justified by the tools they provided for assisting in this process.

desktopos96

Mac OS X ended that reliance on Desktop databases, leaving this to die with Classic Mac OS.

Repairing system permissions

Since its first beta-release, Mac OS X suffered from ill-defined and pervasive problems thought to result from corruption of files used by the system. Until the introduction of System Integrity Protection (SIP) in 10.11 El Capitan, those generally resulted from files within the system acquiring incorrect permissions. Various reasons were proposed for this, including installer scripts that overstepped their bounds.

To address this, Disk Utility had a feature whereby it could check and repair permissions of all major parts of the system, based on information contained in BoM files for system updates and installations. Repairing permissions in this way became one of the main panaceas in older versions of Mac OS X and OS X, and was an important feature in Disk Utility.

Repairing permissions is no longer the panacea that it once was, but is part of checking general disk health.

Although chiefly intended to provide better security protection, one of the benefits of SIP was that it largely prevented system files from gaining incorrect permissions, and the feature to repair them was removed from Disk Utility. In any case, because of SIP it was no longer possible for Disk Utility to change the permissions of files protected by SIP.

Resetting Home permissions

RepairPermissions

When macOS 10.12 Sierra was released, a different problem appeared, in which permissions apparently became set incorrectly not in system files generally, but in the user’s Home folder, and specifically in ~/Library/Preferences. To address this Apple added a new verb to the already complex command tool diskutil, resetUserPermissions, and described how to use this in a support note. It’s perhaps no coincidence that this new problem appeared at about the same time that cfprefsd took on the management of those preference files.

At that time, the following problems were attributed by Apple to incorrect permissions in ~/Library/Preferences:

  • changes to preference settings, particularly those for System Preferences, do not ‘stick’;
  • changes made to the Dock do not ‘stick’;
  • you are asked to authenticate when trying to move or alter some folders in your Home folder;
  • when trying to save, you are told that the file is locked, or that you don’t have permission;
  • Preview, TextEdit, and App Store apps (which are sandboxed) may crash when opened;
  • alerts appear warning that the startup disk has no more space available for app memory;
  • Safari or SafariDAVClient use large amounts of resources (memory);
  • the Mac runs very slowly;
  • iTunes cannot sync a device;
  • there are problems with Photos or iPhoto libraries, including inability to import into the library, or forgetting the library each time the app is opened.

Most if not all of those could be attributable to problems arising from bugs in cfprefsd.

Apple later changed its recommendations to include running a new tool repairHomePermissions in Recovery mode, then re-installing macOS. Shortly afterwards, in June 2020 when Big Sur was in beta, Apple withdrew that support note and all reference to repairing permissions, although the tool is still available in Recovery mode even on Apple silicon Macs.

Cursing privacy protection

Prior to macOS 10.14 Mojave, privacy protection had been limited and largely unobtrusive. We then began to discover that our favourite apps were being locked out of accessing files in many of our working folders.

Thus the era of adding apps to the Full Disk Access list started, and we came to curse the blessing of privacy protection.

Even better, Apple later added extended attributes that could prevent apps perfectly capable of editing documents from being able to save them just when we needed that most. And protected the extended attribute using SIP.

Maybe rebuilding the Desktop databases every couple of months wasn’t so bad after all?

Modern Stories of Lovis Corinth: 1901-1904

With his move to Berlin and the success of his painting of Salome, Lovis Corinth was reaching the peak of his career. Corinth formally joined the Berlin Secession in 1901, and quickly found himself involved with its direction. He relished his new-found reputation as ‘the painter of flesh’, and was now at the centre of Germany’s vibrant city of modern arts.

In 1902, he opened a painting school for women, and among his first pupils was Charlotte Berend (1880-1967), then just twenty-one and the daughter of a rich textile merchant.

The Family of the Painter Fritz Rumpf (1901) is a wonderfully informal family portrait, sadly omitting Fritz Rumpf (1856-1927) altogether, but Corinth painted him separately. The mother, at the right, is Margarethe née Gatterer, and all six of their children are included.

In the summer of 1902, Corinth painted Charlotte Berend for the first time, and the couple travelled to Pomerania together. That autumn they became engaged. By this time, Charlotte had already become Corinth’s muse and preferred model, as she was to remain for the rest of his life. That year, Corinth also visited Paris, Anvers, and the Netherlands.

Lovis Corinth (1858–1925), Self portrait with Charlotte Berend-Corinth (1902), oil on canvas, 98.5 x 108.5 cm, Private collection. Wikimedia Commons.

Self portrait with Charlotte Berend-Corinth (1902) is his earliest double portrait with his fiancée. Its original title in German means self-portrait with his wife and a champagne glass although the glass that he’s holding clearly doesn’t contain champagne. This refers to Rembrandt’s Self-Portrait with Saskia (The Prodigal Son) (1636), below, in which Saskia is sat on Rembrandt’s lap, and he raises a large fluted glass of beer in his right hand. Charlotte, in the role of Saskia, looks quiet and calm, against Corinth/Rembrandt’s alcohol-fuelled mirth.

Presumably Paddling (1902) shows Charlotte’s turn to take to the waters there.

Charlotte Berend and Lovis Corinth married in the spring of 1903. He was 44, she was only 22. In the autumn of the following year, their first child, Thomas, was born, and in 1909 their daughter Wilhelmina.

corinthselfportraitwithmodel
Lovis Corinth (1858–1925), Self-portrait with Model (1903), oil on canvas, 101 × 90 cm, Kunsthaus Zürich, Zürich, Switzerland. Wikimedia Commons.

Self-portrait with Model (1903) is the couple’s second joint portrait, and the first after their marriage. This time her pose refers to the classical images of muses by Rubens and Ingres, alluding to the story of Pygmalion.

Corinth appears to have painted with his left hand, so this image hasn’t been painted directly from a mirror, but he may well have used photographs instead.

Max Reinhardt moved to Berlin at the same time as Corinth, and in 1902 his Little Theatre staged what I think was the German premiere of Oscar Wilde’s play Salome. Richard Strauss saw the play there, and it inspired him to write his opera of the same name the following summer.

corinthgertrudeysoldt
Lovis Corinth (1858–1925), Gertrud Eysoldt as Salome (1903), oil on canvas, dimensions not known, Schlossmuseum, Weimar. Wikimedia Commons.

Corinth painted this wonderful portrait of its star and title role, Gertrud Eysoldt as Salome (1903). This makes an interesting contrast with his 1900 painting of the story. Although during this period he painted fewer mythical and other narrative works, the next painting is one of his most vivid stories.

corinthodysseusbeggar
Lovis Corinth (1858–1925), Ulysses Fighting the Beggar (1903), oil on canvas, 83 × 108 cm, National Gallery in Prague, The Czech Republic. Wikimedia Commons.

Ulysses Fighting the Beggar (1903) shows a story from book 18 of Homer’s Odyssey, before the slaughter of the suitors (painted much earlier by Gustave Moreau, but never completed).

Odysseus/Ulysses has finally returned to his home city of Ithaca and is now determined to kill the many suitors to his wife Penelope. As he plans this, he goes around disguised as a beggar. This fragment of the elaborate story starts with the arrival of a real beggar named Arnaeus or Irus, who most unwisely picks a fight with Odysseus, who promptly floors the beggar, and stops just short of killing him.

Corinth captures the fight as Odysseus (centre) is getting the better of Irus (left of centre), with various suitors and bystanders watching. Although painted loosely, the artist has taken care to give each face its own expression, ranging from amusement to apprehension. The end result is a raucous collage of human emotion.

corinthfrauenraub
Lovis Corinth (1858–1925), Frauenraub (Abduction) (study) (1904), oil on cardboard, 73 × 88 cm, Private collection. Wikimedia Commons.

Corinth seems not to have taken this study of abduction, Frauenraub (1904), any further, and I don’t know its narrative context.

corinthbluhenderbauerngarten
Lovis Corinth (1858–1925), Blühender Bauerngarten (Blooming Farm Garden) (1904), oil on canvas, 76 × 100 cm, Museum, Wiesbaden. Wikimedia Commons.

Landscapes are relatively infrequent over these years, but I could not resist including this delightful Blooming Farm Garden from 1904.

corinthharem
Lovis Corinth (1858–1925), The Harem (1904), oil on canvas, 155 × 140 cm, Hessisches Landesmuseum Darmstadt, Darmstadt. Wikimedia Commons.

Corinth’s reputation as ‘the painter of flesh’ was maintained by two groups of nudes. The Harem (1904) uses an ever-popular ‘oriental’ setting for its abundance of female flesh, but has some distinctive touches too. The cat sat in the foreground ignores, in the way that only cats can, some sort of horseplay taking place behind, while a guard looks as bored as the cat. This isn’t the sumptuous silk and divan lounge shown in the nineteenth century, though. Indeed, it all looks rather tawdry.

In complete contrast, Charlotte Berend in a Deck Chair (1904) is a tender and intimate sketch of his wife relaxing away from their son, her wedding ring prominent on her left hand.

Is Tahoe really macOS 26 or 16?

Although there was no ambiguity in Apple’s announcement that later this year it will be releasing macOS 26 Tahoe, together with version 26 of its other operating systems, there have been claims that this might just be a ‘marketing version’ and not really the case. There is some evidence that could be misinterpreted as confirming that, where some of Apple’s developer web pages refer to macOS 16.

But others choose to differ.

Cast your mind back five years to macOS 11 Big Sur, when what had been expected to be macOS 10.16 but was announced as 11.0 instead. That had the potential to upset a lot of code and scripts that had become used to checking the minor but not major version number. Apple foresaw those problems, and devised an ingenious scheme that allowed Big Sur to be simultaneously both 10.16 and 11.0. It’s hardly surprising that has been implemented once again for Tahoe.

Rules

There are two fundamental rules provided by Apple:

  • In compiled languages, the version returned by macOS depends on the SDK which the software has been built against. When built against the 15 SDK or earlier, Tahoe returns 16 for compatibility with previous numbering and all existing apps; when built against the 26.0 SDK, it returns 26.0 for forward compatibility.
  • In scripted languages run within a shell environment, there’s an environmental variable to control the version number given. Set SYSTEM_VERSION_COMPAT=1 and Tahoe returns 16; leave that variable unset, or SYSTEM_VERSION_COMPAT=0, and it returns 26.

AppleScript

Move a script across to Tahoe, and it will be compiled in the 26 environment, so
system version of (system info)
returns 26.0, as will that code inside an AppleScript app built on Tahoe.

Scripts and other languages

One method commonly used to look up the macOS version number is to obtain the string value for the ProductVersion key in /System/Library/CoreServices/SystemVersion.plist. However, depending on the environment of the caller, Tahoe plays tricks with that file, which should return a version of 26.0. If the caller has set SYSTEM_VERSION_COMPAT=1, then the version number returned isn’t obtained from that property list at all, but its companion SystemVersionCompat.plist, which is 16.0.

You can test this at the command line, by entering the two commands
SYSTEM_VERSION_COMPAT=1 cat /System/Library/CoreServices/SystemVersion.plist
and
SYSTEM_VERSION_COMPAT=0 cat /System/Library/CoreServices/SystemVersion.plist

Which is it – 16 or 26?

macOS Tahoe is very definitely, and not just for marketing purposes, macOS 26, but depending on how you ask that question, it could pretend to be 16 if you wish.

Interiors by Design: Barns and cowsheds

Paintings of the interiors of cowsheds and barns haven’t been prominent, but provide a more continuous record than any other type of interior because of their role in genre paintings of every age after the Renaissance. Here are a few.

Gerard ter Borch put the milkmaid and her cow at the centre of this painting, A Maid Milking a Cow in a Barn from about 1652-54. As was universal at that time, milk was collected in a wooden bucket that would have been scrubbed thoroughly before use, but fell far short of modern standards of hygiene. At the upper right is a store of hay to supplement the cows’ diet during the winter.

David Teniers the Younger’s Barn Interior from about the same period shows a milkmaid pouring freshly collected milk into a large earthenware flask, through a muslin filter. This is taking place under the watchful eye of an older woman, probably the head of the domestic staff. Resting against a barrel is a well-worn besom that has seen good work keeping the floor clean.

In Franz Niklaus König’s Farmers, around the House;, or Farmer Family in the Barn from 1798, one of the early hand-cranked threshing machines is shown on the right, as the farmer is winnowing clouds of chaff from the grain it produced. Most barns were built with large openings at each end, to allow natural breezes to blow the chaff away and leave the denser grain in the large, shallow wickerwork trays used for winnowing. The farmer’s wife, two children and dog are keeping him company as he works.

The Shearers (c 1833-35) is the most ambitious of Samuel Palmer’s paintings from the 1830s. This shows the seasonal work of a shearing gang, in a sophisticated composition that draws the gaze to the brilliant and more distant view beyond. The curious collection of tools to the right was the subject of preparatory sketches, and seems to have been carefully composed. However, they have defied any symbolic interpretation, and may just ‘look right’ for a barn at the time.

Albin Egger-Lienz’s Farm in Grafendorf, from 1890, shows deeply rustic conditions on a dilapidated farm in Styria, Austria, as a young woman sits churning butter on a stone platform in a tumbledown barn. This isn’t the right environment for the preparation of food for human consumption.

Nikolai Astrup’s humorous painting of Early Courting from 1904 shows a young couple at the far left engaged in ‘clothed courting’ in the unromantic surroundings of a cowshed in a Norwegian valley. This couple have sought the privacy of the cowshed, out of everyone’s way, but the boyfriend appears unaware that they’re being watched by someone up in the roof. From the apparent direction of gaze of the girlfriend and the blush on her cheeks, she has just noticed the peeping tom or watchful relative. The setting is enhanced by the sunlight pouring through the far window, illuminating two rows of the back-ends of cows. The wood floor between the cows appears to be decorated with small sketches, but those are actually piles of cow dung. And that’s where I’d like to leave it.

macOS Tahoe brings a new disk image format

Disk images have been valuable tools marred by poor performance. In the wrong circumstances, an encrypted sparse image (UDSP) stored on the blazingly fast internal SSD of an Apple silicon Mac may write files no faster than 100 MB/s, typical for a cheap hard drive. One of the important new features introduced in macOS 26 Tahoe is a new disk image format that can achieve near-native speeds: ASIF, documented here.

This has been detailed as a major improvement in lightweight virtualisation, where it promises to overcome the most significant performance limitation of VMs running on Apple silicon Macs. However, ASIF disk images are available for general use, and even work in macOS Sequoia. This article shows what they can do.

Apple provides few technical details, other than stating that the intrinsic structure of ASIF disk images doesn’t depend on the host file system’s capabilities, and their size on the host depends on the size of the data stored in the disk. In other words, they’re a sparse file in APFS, and are flagged as such.

Make an ASIF disk image

Currently, there are only two ways to create one of these new disk images, either in Tahoe’s Disk Utility, or using its diskutil command tool, as in
diskutil image create blank --format ASIF --size 100G --volumeName myVolume imagePath
to create an ASIF image with a maximum capacity of 100 GB with a single APFS volume named myVolume with the path and name imagePath. You can also use a from option to convert an existing disk image to ASIF format.

These are only good for Tahoe, as there’s no support for their creation in Sequoia 15.5 or earlier. Neither is there any access documented for the hdiutil command tool, more normally used to work with disk images, although its general commands should work fine with ASIFs.

Resulting disk images have a UTI type of com.apple.disk-image-sparse, in contrast to RAW (UDIF read-write) images of type com.apple.disk-image-udif, which can be used to distinguish them.

Economy

When first created, a 100 GB ASIF disk image took less than 1 GB disk space, but after extensive use and adding a second volume, its size on disk when empty again ranged between 1.9-3.2 GB. No attempt was made to compact the disk image using hdiutil, and its man page doesn’t make clear whether that’s supported or effective with this type of disk image.

Performance

Read and write performance were measured using Stibium over a total of more than 50 GB in 160 files ranging in size from 2 MB to 2 GB in randomised order. When performed using a 100 GB ASIF image on the 2 TB internal SSD of a MacBook Pro M3 Pro running macOS 26 beta, transfer speeds for unencrypted APFS were 5.8 and 6.6 GB/s read and write. Those fell to 4.8 and 4.6 GB/s when using an APFS encrypted volume in the disk image.

Although there’s currently no way to create an ASIF disk image on a Mac running Sequoia, I compressed the disk image using Apple Archive (aar) to preserve its format and copied it to a Mac mini M4 Pro running macOS 15.5, and repeated the performance tests on its 2 TB internal SSD. Unencrypted APFS there attained 5.5 and 8.3 GB/s read and write.

Use

Apple recommends switching from the previous RAW (UDIF read-write) disk images used for the backing store of VMs to ASIF for their greater efficiency in file transfer between hosts or disks. As the disk image in a VM is created when the VM is first made and installed, this awaits implementation in virtualisers. Because the only access provided at present is the diskutil command tool, apps will need to consider creating an ASIF image where that’s available, in macOS 26 Tahoe.

Although ASIF appears to be supported by Sequoia 15.5, the danger with a VM based on an ASIF image is that it may not be compatible with older versions of macOS. Apple hasn’t yet revealed which of those can mount and use this new format.

Previous tests on different types of disk image demonstrated that, prior to ASIF, the best performance was achieved by sparse bundles. The following table compares those with ASIF.

Allowing for the differences in chips, ASIF is clearly faster than both UDRW read-write and UDSP sparse images, whether plain or encrypted. It’s also likely to be significantly faster than sparse bundles, and has the advantage that it uses a single file for its backing store.

Conclusions

  • Where possible, in macOS 26 Tahoe in particular, VMs should use ASIF disk images rather than RAW/UDRW.
  • Unless a sparse bundle is required (for example when it’s hosted on a different file system such as that in a NAS), ASIF should be first choice for general purpose disk images in Tahoe.
  • It would be preferable for virtualisers to be able to call a proper API rather than a command tool.
  • Keep an eye on C-Command’s DropDMG. I’m sure it will support ASIF disk images soon.

Reading Visual Art: 216 Scales (weighing)

The scales of justice are of ancient origin. In ancient Egypt, the heart of a dead person was weighed against the feather of truth in the judgement of their soul. That transferred to the Greek goddess of justice Dike, who judged using a set of scales, and so into the personification of justice in ancient Rome, Iustitia, and her modern descendant Lady Justice, whose statue is mounted on many courts of law.

This triple allegorical portrait of The Virtues: Justice, Charity, and Prudence (Wisdom) (1664) is one of Elisabetta Sirani’s more complex works. This shows Charity nursing children, Justice brandishing a sword and holding a set of scales, while Prudence draws attention to their own images.

Photographed 2007 by Carol Highsmith (1946–), who explicitly placed the photograph in the public domain, via Wikimedia Commons.

Elihu Vedder’s most prominent and lasting achievements are the murals in the Lobby to the Main Reading Room of the Library of Congress in Washington, DC. Among them, Corrupt Legislation (1896) is an elaborate composition looking at the consequences of poor government. The central figure is more floozy than goddess, holding a set of scales in her left hand. At the right of the painting, and on that left hand, is a lawyer, with an open book labelled The Law. At his feet, banknotes fall out of an urn, there are small sacks of grain, and a small portable ‘safe’. At the left, apparently pleading with the central figure, is a young girl holding any empty distaff and bobbin for spinning. Behind her are shards from a broken pot, and a broken-down wall.

Time, Death and Judgement 1900 by George Frederic Watts 1817-1904

George Frederic Watts’ Time, Death and Judgement (1900) evolved over a series of versions first started around 1870. Surprisingly, he retained the same composition in all of them, and they differ only in small details. The figure of Time is at the left, holding the traditional scythe; unusually, Watts depicts Time as a young and muscular man, rather than the more conventional ‘Father Time’ with white hair and beard. At the right, Death is a young woman, the lap of her dress containing fading flowers. Time and Death are linked by holding hands. Behind, and towering over them, is the figure of Judgement, holding the scales of justice in her left hand, and brandishing a fiery sword.

Although justice is generally taken to be secular, the concept of weighing the souls of the dead has passed down into some paintings of Christian paradise.

This huge painting of Paradise in the Palazzo Ducale in Venice is seven metres (almost twenty-three feet) high and twenty-two metres (over seventy feet) across, and was probably designed by Jacopo Tintoretto and largely entrusted to his son Domenico and their workshop to paint. In conformity with the rules of the commission, its composition focusses on the Coronation of the Virgin, inspired by Dante’s Paradise, as shown in the detail below.

At the top, the Virgin Mary, behind whom is her traditional symbol of the white lily, stands with Jesus Christ, in their matching red and blue robes. Between them is the white dove of the Holy Ghost, and all around are cherubic heads of infant angels. To the right are the scales of justice, also for the weighing of souls.

This reappears three centuries later in Léon Frédéric’s polyptych All Things Die, But All Will Be Resurrected through God’s Love, painted over the period 1893-1918. Three panels at its right represent Heaven, a pastoral landscape densely packed with a multitude of naked mothers and children. A pair of women in priestly clothing stand at the wings. The figure on the right is holding a stone tablet on which a single word appears: LEX (law), and near her children are playing with the scales of justice. Near the woman at the left two children are swinging censers to generate the smoke of burning incense. Above them all is a double rainbow, and floating in the air the figure of Christ, his arms reaching out over still more figures of children, this time clothed in white robes.

Scales occasionally play a part in legendary history, including the siege of Rome by the Gauls. Conditions drove the Romans trapped in the Capitol to make peace with the Gauls besieged in the rest of the city. Rome was to pay the Gauls a thousand pounds of gold, but even there the Gauls cheated the Romans and tampered with the scales. While this was going on, Camillus entered Rome as its appointed leader, and told the Gauls to quit without any gold, as Rome delivered its city with iron instead.

Francesco de’ Rossi shows this in composite form in his fresco of the Attack on the Gauls who Sacked Rome. In the foreground, the Gauls and Romans are still arguing about the weight of gold, as Camillus’ forces start to take possession of the ruins of what had been Rome.

Finally, scales can appear in their everyday role for weighing out produce in shops and markets.

LogUI build 65 introduces a Logarchive Tool

Just before the start of WWDC, I released an update to my log browser LogUI adding support for accessing logarchives. I promised that there was more support for logarchives on its way. LogUI 1.0 build 65 dedicates a whole window to them, in its Logarchive Tool.

There are many situations where you can’t access the active log, and you can’t create a logarchive using the log command tool or a sysdiagnose. These include:

  • When you only have access to the contents of the Mac or device’s storage, particularly in forensics, or following hardware failure.
  • When you want access to the logs in a backup. Time Machine backups normally include full log files, for example.
  • When you don’t have ssh or similar access to a remote Mac.
  • When the log records may be incomplete or damaged.

Provided that you can copy two folders from the hidden /var/db folder on that Mac or device, LogUI can turn those into a browsable logarchive.

Create a logarchive from folders

On your Mac, create a folder somewhere convenient such as ~/Documents. As this method doesn’t use the log command, this can be on an external disk if you wish.

From the source Data volume copy the folders at /var/db/diagnostics and /var/db/uuidtext to your folder, so it looks like this.

Open LogUI, and from its Window menu open its Logarchive Tool. This offers you four tools and two checkboxes. Click on the Create Logarchive tool and first select the folder you created, containing the log folders. Then give the new logarchive a suitable name and save it somewhere convenient.

LogUI should then inform you in its window that creation has completed. As this is performed using undocumented code for an undocumented format, it may not always work correctly. If there are any problems, repeat the same with the Debug checkbox ticked, and it will give you a detailed commentary of what it does, which should help you understand what went wrong.

Getting info about a logarchive

The trickiest part of accessing logarchives is knowing what they contain, more specifically the time periods for which they have log records. LogUI’s Logarchive window provides two aids to provide you with that information, in its Catalogue and Analyse tools.

Catalogue simply lists all the tracev3 files in the logarchive, giving the datestamps each was created and last modified, together with the period between those, and the file size.

Leave that open as you browse that logarchive, to guide your way through its entries.

Analyse goes further, in telling you about the entries in each of the persist tracev3 files in the logarchive. It tells you the most common processes that wrote the entries in each of those files, allowing you to hone in on which are of most interest. If you want to extract that information for analysis in a spreadsheet, tick the CSV checkbox and it will be shown ready to import into your favourite spreadsheet.

Finally, to save the contents of the current window as a text file, click on the Save Text tool at the right.

I have now checked LogUI’s compatibility with the first developer beta of Tahoe, and found and fixed one obscure bug in the Logarchive Tool before this new build. LogUI should now be fully compatible with macOS 14.6 and later, including Tahoe. It’s available now from here: logui165
and from its Product Page.

Enjoy!

Virtualising macOS 26 Tahoe

The golden rule with any pre-release version of macOS is never to install it on a production Mac, one that you rely on for doing anything important to you. Although even developer betas are generally fairly robust and shouldn’t cause data loss, sometimes they can be catastrophic and require putting your Mac into DFU mode and restoring it from scratch.

Rather than compromise and run Tahoe from a bootable external disk, which only reduces the risk, why not run it in a VM, where it should be safely isolated from the rest of your Mac? Provided that you have an Apple silicon Mac running Sequoia 15.5 and a little time, this is easy to set up. Its major disadvantage is that your VM won’t be able to run the great majority of apps in the App Store, as that still isn’t supported in lightweight VMs. But your VM can have full iCloud access, and its Data volume can be protected by FileVault as well.

Before you try installing your VM, you’ll need to install a software enabler. This can be Device Support for macOS 26 beta, available from Apple’s developer site alongside the IPSW image file for Tahoe, or you can install the beta-release of Xcode version 26 instead. If you do neither, when you try to run your Tahoe VM you’ll be warned, and invited to download the enabler, but that isn’t likely to work, leaving you with an unusable VM.

Then download the IPSW file from Apple’s developer site, or via Mr. Macintosh’s link to Apple, install that and run your VM.

I’m grateful to Joe for letting me know an alternative route, by upgrading an existing Sequoia VM. For that you’ll need the full installer, again through Mr. Macintosh’s link, so you can install that in the VM and run it from there.

These should work with all virtualisation apps, including commercial products like Parallels Desktop, and free apps including my own Viable and Vimy, which also appear fully compatible with Tahoe hosts.

Happy virtual Tahoeing!

Modern Stories of Lovis Corinth: 1898-1900

Lovis Corinth didn’t just spend his years in Munich drinking red wine and champagne, but experimented in his painting and evolved his mature style. In 1897, he moved studio within Munich, and started making increasingly frequent visits to Berlin, where he was able to obtain lucrative commissions for portraits. Corinth was among the founding members of the Berlin Secession in 1898, and by 1900 was renting a studio in Berlin. In the autumn of 1901, he closed his studio in Munich and moved fully to Berlin.

He had no shortage of attractive young women, like Ellÿ (1898), to paint, but he pressed on with his campaign to improve his style and technique.

Reclining Nude (1899) is usually considered to mark the peak of Corinth’s nudes, and was painted during one of his visits to Berlin. Its brushwork is so painterly that it has sometimes been mistakenly supposed that it was made well into the twentieth century, but is now securely dated to the end of his time in Munich.

In Max Halbe’s Garden (1899) shows a group of friends in an informal setting, chatting as they eat fruit next to the washing line. Max Halbe (1865-1944) was a German playwright with a growing reputation at the time, and is seen to the right of centre, with his wife at the right.

In addition to single-person portraits, Corinth was commissioned to paint a few group portraits, including this of The Lodge Brothers from 1898-99. He modelled this after Rembrandt’s smaller group portraits, placing the Master of the Lodge in the centre, where his gaunt face stares up to the heavens.

In these last few years in Munich, Corinth worked on a series of two paintings exploring the story of Salome and John the Baptist’s execution. He seems to have started this work with a drawing in 1897, which eventually led to one of his greatest paintings.

The original narrative is biblical, and straightforward: the unnamed daughter of Herodias (subsequently identified as Salome) performed a dance at a birthday feast thrown by King Herod. The dance so pleased Herod that he offered her anything that she wanted, up to half his kingdom. She asked not for riches, but for the head of Saint John the Baptist, the earthly messenger sent to announce the birth and ministry of Jesus Christ. Herod reluctantly agreed, John was beheaded in prison, and his head brought to her on a plate, which the dancer gave to her mother.

A popular story for religious paintings, Corinth decided to paint a scene close to that most commonly chosen, in which John’s head has been brought to Salome on a platter. This contrasts with the choices made by Gustave Moreau almost twenty-five years earlier.

The basic cast and arrangement of figures is the same in each version: the severed head of John the Baptist is at the centre, Salome leaning over and touching it with her right hand. Behind her are two women. The receptacle containing John’s head is itself on the head of a slave, who kneels at the feet of the executioner, who stands holding the bloodied sword in his right hand, facing Salome. To the lower right, three other figures are partly cropped out: the feet of John’s dead body, and another slave bent over them to look at the head of an older man.

Corinth’s first painting of Salome from 1899 shows the dancer dressed as a tart, her breasts hanging loose, her face sneering down at John’s face with contempt as she touches it. The young woman at the top right laughs as she looks towards the left, apparently detached from the gruesome scene in front of her. No gazes meet, thus the figures do not integrate into a whole.

corinthsalome1900
Lovis Corinth (1858–1925), Salome (II) (1900), oil on canvas, 127 × 147 cm, Museum der Bildenden Künste Leipzig, Leipzig. Wikimedia Commons.

His second Salome from the following year is less roughly worked and more finished to show finer detail. Although its figures haven’t moved, subtle changes have transformed the painting and its reading.

Salome has a more neutral facial expression, and is staring intently at the lower abdomen of the executioner. Her right hand is stretching open the left eye of John’s head, which appears to be staring up at her. The executioner and the young woman at the top right are laughing at one another, but the third woman beside her has a serious, almost sad expression, as she stands holding a large peacock fan. Visible at the top of her clothing, directly below her chin, is the small image of a human skull.

Corinth has also added detail to the cropped figures at the lower right. John’s legs are spattered with his blood, and possibly bear wounds or sores from his imprisonment. The two figures there are engaged in eye-to-eye contact, and there is also a profusion of hands there, as the older man appears to be raising John’s right arm.

Lovis Corinth (1858–1925), Salome (II) (detail) (1900), oil on canvas, 127 × 147 cm, Museum der Bildenden Künste Leipzig, Leipzig. Wikimedia Commons.

The chain of gaze here is central to the painting’s narrative: John’s eye stares at Salome, who stares at the executioner’s crotch, who laughs at the young woman at the top right, who laughs back at him. Watching sombre and detached from behind is the figure of death.

Oscar Wilde’s one-act play Salome had been first published in French in 1891, and was soon translated into English and German. Banned from public performance in Britain, it received its premier in Paris in 1896, but wasn’t performed in public in England until 1931. Wilde had been influenced by Gustave Moreau’s paintings of Salome, and in turn influenced both Corinth’s paintings and Richard Strauss’s later opera (1905).

In Salome’s words at the end of Wilde’s play (he calls John the Baptist Jokanaan):
But, wherefore dost thou not look at me Jokanaan? Thine eyes that were so terrible, so full of rage and scorn, are shut now. Wherefore are they shut? Open thine eyes! Lift up thine eyelids, Jokanaan! Wherefore dost thou not look at me? Art thou afraid of me, Jokanaan, that thou wilt not look at me?
If thou hadst looked at me thou hadst loved me. Well I know that thou wouldst have loved me, and the mystery of love is greater that the mystery of death.

At the centre of Wilde’s play is the perversion of lust and desire in Salome, captured so well by Corinth in the chain of gaze.

This second painting was rejected by the Munich Secession, but welcomed by the Berlin Secession. As a result, Corinth was dubbed ‘the painter of flesh’, establishing his reputation and securing his future in Berlin.

macOS 26 Tahoe is coming

As expected, Apple announced the next major version of macOS and its other operating systems, on the opening day of WWDC yesterday. This followed a disarming vision of Craig Federighi sporting a forest of grey hair and racing a Formula 1 car around the roof of Apple Park. Mercifully, that turned out to be a promotion for a new Apple TV+ production titled F1, rather than anything about to happen to macOS. And he didn’t crash.

Previews of each new OS were prefaced by the promise of “big announcements for all of our platforms”, and inevitably opened with plans for Apple Intelligence and Private Cloud Compute. Language support is going to be further extended, and additional new features are going to be announced later during this cycle. Perhaps most important is the news that third-party developers are to be given access to on-device Large Language Models (LLMs) through a Foundation Models Framework. This looks highly accessible, and it will be exciting to see what that enables.

As widely forecast, these new major versions bring a redesign intended to harness the power of Apple silicon, with a look dubbed Liquid Glass. This features layers of translucent controls that adapt to your actions, for example moving out of the way when scrolling. Although this is harmonised across devices, fears that macOS will be ‘dumbed down’ to resemble iOS appear unfounded. Indeed, iPadOS is steadily moving closer to macOS with a more Finder-like Files app, and iPads will at last be able to run background tasks.

Some features of Liquid Glass appear visually stunning, for example when providing 3D effects of depth in lock screen photos. Overall, from the little that has been shown so far, it looks impressive without being obtrusive or irritating. To get the best out of Liquid Glass, apps will need to be rebuilt against the improved API, and their appearance tuned lightly. Some special visual effects may need access to new API features, though.

To get the best out of this new look, icons need to be layered, and adapted for new appearance options including transparent. Apple has provided a new Icon Composer app to support that. Although I doubt whether it will become as popular as ResEdit was in Classic Mac OS, I can see Icon Composer being used more widely than the rest of Xcode.

Hardware support

Surprisingly, four Intel models continue to be supported by Tahoe. The full list given by Apple reads:

  • MacBook Pro 16-inch 2019, and 13-inch 2020 with four Thunderbolt ports,
  • iMac 2020,
  • Mac Pro 2019,
  • all Apple silicon models from 2020 onwards.

Although those Intel models will be able to use many of the new features in Tahoe, they continue to be unable to access any Apple Intelligence.

This means that Tahoe will continue to be a large Universal binary, and could in theory be supported by OCLP, although that’s likely to be more challenging. Apple has stated explicitly that Tahoe will be the last major version of macOS to support Intel Macs.

Version numbering

As rumoured, Apple has changed the numbering of all its OSes, bringing them in synchrony to version 26. This even applies to the new beta-release of Xcode for Tahoe.

Although that might come as a surprise to some code and scripts, because it’s a higher major version number than Sequoia this should present far fewer problems than did macOS 11 Big Sur. You might still like to check anything of yours that does check version numbers to ensure it doesn’t trip up.

Details

In keeping with the redesign, improvements in folder and icon appearance were mentioned early. Easy folder customisation is coming, allowing the standard icon to be enhanced with the superimposition of symbols and emoji, and its colour changed. Icons can be tinted by the user, as well as being layered in Icon Composer.

Continuity features that integrate Macs with devices are being extended with support for Live Activities added to macOS. The Phone app will be added as well, in its improved form from iOS 26.

Shortcuts gains ‘intelligent’ actions, and will have direct access to LLMs in Private Cloud Compute. Spotlight has undergone a major update, but in Global Spotlight features rather than local search. From the Spotlight icon, there will be intelligent actions integrated with Shortcuts, quick keys abbreviations, and it will be contextually aware. To take advantage of these, third-party apps will need to use App Intents.

Games will be integrated into a new Games app, and gain translucent controls.

The powerful GPUs in Macs supported by Tahoe should also become more capable, with the introduction of Metal 4.

Finally, Tahoe is dropping full first run security checks on notarized apps, which should ensure they all launch blazingly fast. Although a few malicious apps have been inadvertently notarized in the past, running XProtect checks on them seem pointless, as the notarization process involves more extensive checks than those performed by XProtect. If malware has managed to sneak past Apple’s checks and become notarized, then nothing in macOS is going to detect it as being malicious.

Release dates

Apple has already released the first developer beta-test version of Tahoe and its sister OSes. The first public beta is promised for July, and full release of macOS 26.0 is due in the fall/autumn.

I’ve already started testing my own apps.

Changing Paintings: 74 The Age of Augustus

With Julius Caesar transformed into a star following his assassination, Ovid ends the last book of his Metamorphoses with praise of the contemporary Emperor Augustus, and expresses his own aspirations to immortality.

Jupiter foretells some of the accomplishments of Caesar’s adopted heir, Augustus, who was then still known as Octavius or Octavian. These include successes in battle, the fall of Cleopatra, Queen of Egypt, and the growth of the Roman Empire. Ovid then looks ahead to Augustus’ own future apotheosis, when he will become a god. Finally, the author wishes for his words to be read throughout the empire, and to live on in fame.

Cleopatra’s legendary beauty has been expressed in paint by several artists, among them Louis Gauffier, whose Cleopatra and Octavian of 1787 shows the young Augustus and Queen Cleopatra conversing under the watchful eye of Julius Caesar’s bust. Cleopatra allied herself with Antony, and was eventually defeated at the Battle of Actium, ending years of civil war in Rome. Antony fell on his sword, and Cleopatra is reputed to have killed herself with the bite of an asp.

It’s Jean-Léon Gérôme who reminds us of the great events that were taking place at the eastern end of the Mediterranean during the reign of Augustus, in The Age of Augustus, the Birth of Christ (c 1852-54). The emperor sits on his throne, overseeing a huge gathering of people from all over the Roman Empire. Grouped in the foreground in a quotation from a traditional nativity is the Holy Family, whose infant son was to transform the empire in the centuries to come. Sadly for Ovid, and even Virgil, Gérôme’s throng doesn’t appear to include distinguished poets from the Augustan age.

Several painters have, though, shown Augustus’ favourite Virgil at the emperor’s court. Jean-Joseph Taillasson’s Virgil reading the Aeneid to Augustus and Octavia from 1787 shows the poet at the left, holding a copy of his Aeneid, reading a passage to the emperor Augustus and his sister Octavia. Augustus has been moved to tears by the passage praising Octavia’s dead son Marcellus, and his sister has swooned in her emotional response.

Ovid was in no position to commit Augustus’ eventual death and apotheosis to verse, but this is shown in an exquisite sardonyx cameo known as The Great Cameo of France from the first century CE. Augustus is here being brought up to the gods at the top of the scene.

Although a fan of Virgil and a minor author in his own right, Augustus wasn’t a strong patron of the arts. Until 8 BCE, his friend Gaius Maecenas acted as cultural advisor to Augustus, and was a major patron of Virgil. Tiepolo’s Maecenas Presenting the Liberal Arts to Emperor Augustus from 1743 shows Maecenas at the left introducing an anachronistic woman painter and other artists to the emperor.

Ovid’s major patron was Marcus Valerius Messalia Corvinus, and is thought to have been friends with poets in the circle of Maecenas. But all this became irrelevant when Ovid offended Augustus, and in 8 CE was banished to Tomis, on the western coast of the Black Sea, at the north-eastern edge of the Roman Empire.

It is perhaps JMW Turner who has best captured this in his Ancient Italy – Ovid Banished from Rome, exhibited in 1838. In a dusk scene more characteristic of Claude Lorrain’s contre-jour riverscapes, Turner gives a thoroughly romantic view of Ovid’s departure by boat from the bank of the Tiber.

Ovid died in Tomis in 17 or 18 CE, and by a quirk of fate his banishment from the city of Rome wasn’t formally revoked until 2017, two millennia later.

But Ovid saw his road to immortality not by apotheosis, rather through his work being read, and living on in the minds of those countless readers. In that, he undoubtedly succeeded: his Metamorphoses and other poems continue to be read, both in their original Latin and in translation into many languages, and depicted in many great paintings.

LogUI build 60 reads iOS, iPadOS, macOS and other logarchives

Until now, LogUI has only been able to access the active log of your Mac, by reading it directly. There are occasions when you can’t do that, or want to preserve the log for future reference. You also can’t browse the log directly on any of Apple’s devices. In these cases, and others, the best solution is to make a logarchive, and browse that instead. I’m delighted to provide an update to LogUI that can browse logarchives, including those created in iOS, iPadOS, and on Apple’s other devices.

What is a logarchive?

A logarchive is an undocumented package containing copies of all the files from the active log at the moment the logarchive was created. They can be opened and browsed by Console, Consolation 3, Ulbow, the log command tool, and now by LogUI. Because they contain all the files that make up the log, they can be large, and typically range in size from about 300 MB to over 1 GB. All the files containing log entries are stored in their original binary tracev3 format, proprietary to Apple, and again undocumented, although that format has been reversed in the past.

Create a logarchive

The easiest way to create a logarchive is to run a sysdiagnose, and that’s the standard way for saving a logarchive on one of Apple’s devices. Methods vary by device, and include:

  • On a Mac, use the System Diagnostics… option in Activity Monitor’s Action tool, or press the Shift, Command, Control, Option and . keys at the same time, or run sudo sysdiagnose -f ~/Documents to save it to your Documents folder.
  • On an iPhone or iPad, press and hold both volume buttons and the side or top button at the same time, for about 2 seconds. This combination may trigger other features, though. The sysdiagnose file will be made available in Settings > Privacy & Security > Analytics & Improvements > Analytics Data, from where you can transfer it to your Mac.

Unpack the .tar.gz archive resulting from that, and you’ll find a system_logs.logarchive inside it.

On a Mac, you can instead use the log collect command to create a logarchive directly. For example,
log collect --output ~/Documents/my.logarchive --last 5m
collects the last 5 minutes of log in the specified logarchive package. macOS security will block you from trying to save that logarchive on an external volume, though.

My free log browser Ulbow uses another method for assembling logarchives, and the next build of LogUI will incorporate that and other tools for working with logarchives.

Browse a logarchive in LogUI

This new build of LogUI has a seventh tool, to Use Logarchive. Click on that and you’ll be prompted to select the logarchive to open and browse.

Because the dates and times used in the logarchive will be different from current clock time, the LogUI window displays red warning text just to the left of the Start time. Set the date and time to a period within the scope of that logarchive, and use the Get Log tool as normal.

The log excerpt shown in the screenshot above is taken from the kernel boot sequence of my iPhone 15 Pro, to demonstrate how this all works.

If you want to return that window to browsing the active log, click on the Use Logarchive tool again, but this time cancel the selection. Other windows will of course continue to browse the active log unless you set them to use a logarchive as well.

Coming soon

Although browsing saved log entries in a logarchive is exactly the same as those of the active log, dates and times can be a pain. If you want to check when log files in a logarchive were written, use the Finder’s contextual menu to show their contents, scroll to the foot of the folders inside, select the Persist folder and check the file creation dates there.

This is made even easier in the forthcoming new build of LogUI, which features a Logarchive Tool to help you navigate logarchives, and learn which date and time ranges are appropriate.

LogUI 1.0 build 60 is now available from here: logui160
and from its Product Page.

I’ll be along with a new build in a few days, once I have tested and documented its Logarchive Tool. In the meantime, I hope you’ll find LogUI useful for studying the first beta-releases of Apple’s new operating systems.

Paintings of the Danish countryside: Zealand 2

This is the second of two articles looking at paintings of the Zealand countryside from the early nineteenth century up to the 1930s. I have reached the start of the twentieth century, and proceed with the landscapes of the two Andersens, Laurits Andersen Ring and Hans Andersen Brendekilde.

Laurits Andersen Ring (1854–1933), By the Village Pond at Baldersbrønde (1911), oil on canvas, 50 x 63 cm, Private collection. Wikimedia Commons.

After LA Ring married Sigrid, daughter of the ceramicist Herman Kähler, the family settled in the village of Baldersbrønde, midway between what’s now the western edge of Copenhagen’s conurbation, and the city of Roskilde, on Zealand. By the Village Pond at Baldersbrønde from 1911 shows this village with its rutted mud track, in early Spring when the pollards are still bare of leaves.

The other painting Andersen of the day was LA Ring’s friend and contemporary originally named Hans Andersen, who adopted the surname of Brendekilde after the village of Brændekilde, on the island of Funen (Fyn), where he was born.

Brendekilde’s A Sower on a Sunny Spring Day at Brendekilde Church from 1914 shows Holme-Olstrup Church, near Næstved on Zealand. The sower, walking over poor soil with abundant stones, has been identified as Ole Frederik Jensen (1870-1953).

LA Ring later moved to the tiny rural island of Enø, linked to Zealand by a bridge at Karrebæksminde.

The Bridge at Karrebæksminde from 1912 must be one of Ring’s most intricately detailed works, showing the bridge connecting the large and populous island of Zealand with tiny Enø. This canal was dug in the early nineteenth century to connect Karrebæk Fjord with the waters of the Baltic, and has a strong tidal stream, as demonstrated here.

By 1911, LA Ring and his family had bought a caravan, which in those days resembled a railway goods wagon and usually weighed several tons. Most had to be towed by a truck or one of the traction engines still used on farms, and were barely mobile. The Artist’s Wife with the Family Caravan (1911) shows his wife Sigrid in a loose-fitting dress, under the shade of a parasol, enjoying a holiday amid sand dunes, somewhere on the Danish Baltic coast.

In the summer of 1913 Ring and his family holidayed again in their caravan. In his View of a Shore with the Artist’s Wagon and Tent at Enö, they are seen on the south-west coast of the island of Enø. They have spilled out into a tent, whose heavy guy ropes are being used to dry washing.

After the start of the First World War, LA Ring retired to a house built for him near the city of Roskilde, in the centre of Zealand. This was ideally situated in what was then the neighbouring village of Sankt Jørgensbjerg. Although generally flat and low country, the land rises to 40 metres (130 feet) above the water of Roskilde Fjord. Ring’s house and environs gave him fine views over the city, country, and the fjord itself to the north, that dominated his paintings during the final eighteen years of his life.

In the winter of 1916 he painted one of his finest landscapes, View of Roskilde from Sankt Jørgensbjerg. It’s a dull grey day, with the snow still lying on the ground. Although distant, the great cathedral dominates from its position at the top of the hill. In seemingly painting every single branch and twig on the barren trees, Ring has brought a fine, rhythmic texture to the foreground that extends right to the skyline. The detail below shows his rich vocabulary of textures in the trees, field, and buildings, which compensate for the muted colours.

One of the last of LA Ring’s landscapes shows this View Over the Roofs at Sankt Jørgensbjerg, Denmark, from 1932. By this time, he was 78, still a superb artist with great precision in his detail of the leafless trees, and in the texture of the thatch. The church behind the trees is that of Sankt Jørgensbjerg, and this view is from the artist’s house.

Last Week on My Mac: The Swiss Army knife of search

The Swiss Army knife has fallen victim to unintended consequences. Once the dream of every schoolboy and pocketed by anyone who went out into the countryside, my small collection of Swiss Army knives and multi-tools now remains indoors and unused. This is the result of strict laws on the carriage of knives in the UK; although not deemed illegal, since 1988 carrying them in a public place has put you at risk of being stopped and searched, and one friend was subjected to that for carrying a mere paint-scraper.

Swiss Army knives have another more sinister danger, that they’re used in preference to dedicated tools. Over the last week or two as I’ve been digging deeper into Spotlight, I can’t help but think how it has turned into the Swiss Army knife of search tools, by compromising its powers for the sake of versatility.

At present, I know of four different Spotlights:

  • Global Spotlight, incorporating local, web, and some in-app search, accessed through the Spotlight tool in the menu bar;
  • Local Spotlight, restricted to searching files in local and some network storage, typically through a Find window in the Finder;
  • Core Spotlight, providing search features within an app, commonly in the contents of an app’s database;
  • Third-Party Local Spotlight, a more limited local search available to third-party apps.

Of those, it’s Global Spotlight that I find most concerning, as it’s the frontline search tool for many if not most who use Macs, and the most flawed of the four. It’s not even the fault of Spotlight, whose 20th birthday we should have celebrated just over a month ago. No, this flaw goes right back to Sherlock, first released in Mac OS 8.5 in 1998.

At that time, few Macs had more than 5 GB of hard disk storage, and local search typically dealt with tens of thousands of files. That was also the first year that Google published its index, estimating that there were about 25 million web pages in all. Apple didn’t have its own web browser to offer, but made Microsoft’s Internet Explorer the default until Safari was released five years later. Merging local and web search into a single app seemed a good idea, and that’s the dangerous precedent set by Sherlock 27 years ago.

The result today only conflates and confuses.

spotlighticloud

In the days of Sherlock, web search was more a journey of discovery, where most search engines ranked pages naïvely according to the number of times the search term appeared on that page. That only changed with the arrival of Google’s patented PageRank algorithm at the end of the twentieth century, and placement of ads didn’t start in earnest until the start of the new millennium, by which time Safari was established as the standard browser in Mac OS X.

Local search was and remains a completely different discipline, with no concept of ranking. As local storage increased relentlessly in capacity, file metadata and contents became increasingly important to its success. Internally local searches have been specified by a logical language of predicates that are directly accessible to remarkably few users, and most of us have come to expect Spotlight’s indexing to handle metadata for us.

The end result challenges the user with negotiating web search engines and dodging their ads using one language, confounded by the behaviour of Siri Suggestions, and hazarding a wild guess as to what might come up in the metadata and content of files. More often than not, we end up with a potpourri that fails on all counts.

As an example, I entered the terms manet painting civil war into Spotlight’s Global Search box and was rewarded with a link to Manet’s painting of The Battle of the Kearsarge and the Alabama from 1864, as I’d hope. But entered into the search box of a Find window, those found anything but, from Plutarch’s Lives to a medical review on Type 2 diabetes. In MarsEdit’s Core Spotlight, though, they found every article I have written for this blog that featured the painting.

Édouard Manet (1832–1883), The Battle of the Kearsarge and the Alabama (1864), oil on canvas, 134 x 127 cm, Philadelphia Museum of Art, Philadelphia, PA. Wikimedia Commons.

To get anything useful from local Spotlight, I had to know one of the ships was the USS Kearsarge, and that unusual word immediately found an image of the painting, but no useful content referring to it. Had I opted to search for the word Alabama instead, I would have been offered 94 hits, ranging from linguistics to the Mueller report into Russian interference in the 2016 US Presidential election. Adding the requirement that the file was an image narrowed the results down to the single image.

Conversely, entering Kearsarge into Global Spotlight offered a neighbourhood in North Conway, New Hampshire, in Maps, information about three different US warships from Siri Knowledge, Wikipedia’s comprehensive disambiguation page, a list of five US warships of that name, and three copies of the image of Manet’s painting without any further information about them.

Spotlight is also set to change with the inevitable addition of AI. Already suggestions are tailored using machine learning, but as far as I’m aware local Spotlight doesn’t yet use any form of AI-enhanced search. Words entered into search boxes and bars aren’t subject to autocorrection, and although Global Spotlight may suggest alternative searches using similar words, if you enter acotyle Spotlight doesn’t dismiss it as a mistake for acolyte. It remains to be seen whether and when local Spotlight switches from Boolean binaries to fuzziness and probability, but at least that will be more akin to the ranking of web pages, and we’ll no longer need to be bilingual.

For the time being, we’re left with a Swiss Army knife, ideal for finding where Apple has hidden Keychain Access, but disappointing when you don’t know exactly what you’re looking for.

Paintings of the Danish countryside: Zealand 1

The island of Zealand (Sjælland) lies between Germany and Scania (Skåne) in southern Sweden, on the south-western edge of the Baltic Sea, and is the most populous of the Danish islands. The capital Copenhagen (København) is on its eastern coast, looking across Øresund, the strait separating it from Malmö in Sweden.

Like most European cities, Copenhagen grew rapidly during the nineteenth century, from a population of just over 100,000 to four times that in 1901. Many of those migrated from the surrounding countryside, where they had farmed the land. This weekend I show paintings of the Zealand countryside from the early nineteenth century up to the 1930s.

Although JC Dahl had been born in Norway, he painted for much of his early career in Copenhagen, and later returned to the Zealand countryside. In 1829, he painted this Winter Landscape at Vordingborg, showing barren trees and snowy fields near the town of Vordingborg, in the south of Zealand. Plenty of sinister crows in the air and on the ground help build the sense of grim foreboding.

Painted in 1856, his Burning Windmill at Stege is an unusual brandje (a painting of fire) following a traditional sub-genre of the Dutch Golden Age. Although completed well before Impressionism, Dahl echoes the red of the flames in the field and trees to the left of the windmill, and even in his signature. Stege is a small town on an island in the south of the Zealand archipelago.

Laurits Andersen adopted his surname Ring from the village where he was born in the south of Zealand. His Young Girl Looking out of a Roof Window (1885) eloquently expresses the feelings of a migrant from the countryside when trapped in a garret amid the grey urban roofscape of Copenhagen.

His painting of Harvest shows his brother cutting what’s most probably rye rather than wheat, as a “monument to the Danish peasant”. He painted this during the summer of 1885, when his brother was working on his farm near Fakse on Zealand.

Erik Henningsen’s painted record of Farmers in the Capital from 1887 is one of the few contemporary accounts of migrants from the country. This family group consists of an older man, the head of household, two younger women, and a young boy. Everyone else is wearing smart leather shoes or boots, but these four are still wearing filthy wooden clogs, with tattered and patched clothing. The two men are carrying a large chest containing the family’s worldly goods, and beside them is their farm dog. The father is speaking to a mounted policeman, presumably asking him for directions to their lodgings. The large brick building in the background is the second version of Copenhagen’s main railway station, opened in 1864, and replaced by the modern station in 1911.

LA Ring’s Mogenstrup Church (1888-89) shows an elderly couple in their tattered Sunday best clothing, slowly making their way home after attending this church near his home village of Ring. The man’s shoes are still polished and his top hat also shiny, but like many country couples these two were no strangers to hunger or deprivation.

In 1891, Ring visited Herman Kähler’s ceramics factory in Næstved in the south of Zealand, and in the adjacent village painted this rural genre work, Conversation in the Countryside, Lille Næstved. It shows a mother with her two young children talking to an older boy, who sits on a doorstep staring at the viewer. Although the mother and family appear clean and fairly well-dressed, the boy’s clothing is worn out and tattered. Running behind them is the small stream that functioned as the dirt road’s main drain. Most of the cottages are small, and thatched, with the chimney of Kähler’s factory in the background.

ringcarlsmindebog

The bog at Carlsminde in Søllerød, Zealand from 1906 is one of LA Ring’s finest landscapes, although perhaps more appropriate for pre-Impressionist painting in the middle of the nineteenth century. It shows a lake in the grounds of a Baroque mansion in Søllerød, to the north of Copenhagen. This estate had been bought by Isak Glückstadt in 1903, who expanded it and had it landscaped around this lake, with its stock of pike and tench. Glückstadt seems to have been eccentric, at one time keeping two Indian elephants here.

Saturday Mac riddles 311

Please don’t post your solutions as comments here: it spoils it for others.

A brief history of local search

Spotlight, the current search feature in macOS, does far more than find locally stored files, but in this brief history I focus on that function, and how it has evolved as Macs have come to keep increasingly large numbers of files.

Until early Macs had enough storage to make this worthwhile, there seemed little need. Although in 1994 there were precious few Macs with hard disks as large as 1 GB, networks could provide considerably more. That year Apple offered its first product in AppleSearch, based on a client-server system running over AppleShare networks, and in its Workgroup Servers in particular. This was a pioneering product that was soon accompanied by a local app, Find File, written by Bill Monk and introduced in System 7.5 that September.

Sherlock

The next step was to implement a similar architecture to AppleSearch on each Mac, with a service that maintained indexes of file metadata and contents, and a client that passed queries to it. This became Sherlock, first released in Mac OS 8.5 in 1998. As access to the web grew, this came to encompass remote search through plug-ins that worked with web search engines.

Those were expanded in Sherlock 2, part of Mac OS 9.0 from 1999 and shown above, and version 3 that came in Mac OS X 10.2 Jaguar in 2002. The latter brought one of the more unseemly conflicts in Apple’s history, when developers at Karelia claimed Sherlock 3 had plagiarised its own product, Watson, which in turn had been modelled on Sherlock. Apple denied that, but the phrase being Sherlocked has passed into the language as a result.

Spotlight

Sherlock remained popular with the introduction of Mac OS X, but was never ported to run native on Intel processors. Instead, Apple replaced it with Spotlight in Mac OS X 10.4 Tiger, in April 2005.

Initially, the Spotlight menu command dropped down a search panel as shown here, rather than opening a window as it does now.

A Finder search window, precursor to the modern Find window, is shown in the lower left of this screenshot taken from Tiger in 2006.

Spotlight was improved again in Mac OS 10.5 Leopard, in 2007. This extended its query language, and brought support for networked Macs that were using file sharing.

This shows a rather grander Finder search window from Mac OS X 10.5 Leopard in 2009.

Search attributes available for use in the search window are shown here in OS X 10.9 Mavericks, in 2014.

Spotlight’s last major redesign came in OS X 10.10 Yosemite, in 2014, when web and local search were merged into Global Spotlight, the search window that opens using the Spotlight icon at the right end of the menu bar. With Global Spotlight came Spotlight (then Siri from macOS Sierra) Suggestions, and they have been accompanied by remote data collection designed to preserve the relative anonymity of the user.

This Finder window in OS X 10.10 Yosemite, in 2015, shows a more complex search in progress.

spotlighticloud

This shows a search in Global Spotlight in macOS 10.12 Sierra, in 2017.

searchkey24

Local Search in the Finder’s Find window can now use a wide variety of attributes, some of which are shown here, in macOS 10.13 High Sierra, in 2018. Below are search bars for several different classes of metadata.

searchkey25

Over the years, Spotlight’s features have become more divided, in part to safeguard privacy, and to deliver similar features from databases. Core Spotlight now provides search features within apps such as Mail and Notes, where local searches lack access.

spotlightsteps1

Spotlight’s indexes are located at the root level of each indexed volume, in the hidden .Spotlight-V100 folder. Those are maintained by mdworker processes relying on mdimporter plugins to provide tailored access for different file types. If an mdimporter fails to provide content data on some or all of the file types it supports, those are missing from that volume’s indexes, and Spotlight search will be unsuccessful. This happened most probably in macOS Catalina 10.15.6, breaking the indexing of content from Rich Text files. That wasn’t fixed until macOS Big Sur 11.3 in April 2021.

Over the last few years, macOS has gained the ability to perform optical character recognition using Live Text, and to analyse and classify images. Text and metadata retrieved by the various services responsible are now included in Spotlight’s indexes. From macOS 13 Ventura in 2022, those services can take prolonged periods working through images and file types like PDF that include images they can process to generate additional content and metadata for indexing.

Those with large collections of eligible files have noticed sustained workloads as a result. Fortunately for those with Apple silicon Macs, those services, like Spotlight’s indexing, run almost exclusively on their Mac’s E cores, so have little or no effect on its ability to run apps. For those with Intel processors, though, this may continue to be troubling.

In less than 30 years, searching Macs has progressed from the basic Find File to Spotlight finding search terms in text recognised in photos, in almost complete silence. Even Spotlight’s 20th birthday passed just over a month ago, on 29 April, without so much as an acknowledgment of its impact.

Modern Stories of Lovis Corinth: 1891-97

By 1890, Lovis Corinth was financially independent, had his own studio in Königsberg, the city near his home village, and was starting to become a successful artist. His Pietà from 1889, which was sadly destroyed in 1945, received an honourable mention at the Paris Salon of 1890; encouraged by that and the greater prospects of working in what was then the arts capital of Germany, he moved to Munich in 1891.

corinthviewfromstudio
Lovis Corinth (1858–1925), View from the Studio, Schwabing (1891), oil on cardboard, 64.5 × 50 cm, Private collection. Wikipedia Commons.

Corinth set up his studio in what was at the time the most bohemian and artistic district of Munich, and painted this quick sketch of the View from the Studio, Schwabing (1891). He realised that his progressive style of painting was at variance with both the Munich Academy and the critics, and in 1892 he took part in the foundation of the Munich Secession to bring change. The following year he co-founded the Free Association (Freie Vereinigung). He also expanded his skills, started etching in 1891, and lithography in 1894.

Much of his painting during his nine years in Munich was experimental, although modern critics accuse him of spending more time drinking copious quantities of red wine and champagne.

He painted this Self-portrait with Skeleton in his Munich studio in 1896, and shows in his face the effects of his high life in Munich.

corinthlargeraven
Lovis Corinth (1858–1925), Landscape with a Large Raven (1893), oil on canvas, 96 × 120 cm, Städelsches Kunstinstitut und Städtische Galerie, Frankfurt. Wikipedia Commons.

In the 1890s he started to take landscape painting more seriously, including this Landscape with a Large Raven painted in the late autumn of 1893. As in Vincent van Gogh’s late landscapes, ravens, crows, and other similar black birds are taken as harbingers of death. In this otherwise deserted countryside, with the winter drawing close, this painting could be read as indicating Corinth’s bleak melancholy. Although he certainly suffered feelings of mortality and had episodes of depression, those aren’t part of the received image of his social life, nor of many of his paintings.

Lovis Corinth (1858–1925), Cemetery in Nidden (1893), oil on canvas, 112 × 148 cm, Neue Pinakothek, Munich. Wikipedia Commons.

This shows the beautiful fishermen’s Cemetery in Nidden (1893) on the Kurische Nehrung, a long sand spit near the southern border of Lithuania, on the shore of the Baltic not far from Königsberg. During the 1890s, Corinth travelled from Munich to visit his home village, and went as far afield as Italy.

corinthinslaughterhouse
Lovis Corinth (1858–1925), In the Slaughterhouse (1893), oil on canvas, 78 × 89 cm, Staatsgalerie Stuttgart, Stuttgart. Wikipedia Commons.

Like some of the Masters before him, most notably Rembrandt, he painted a series of studies In the Slaughterhouse (1893). As the son of a tanner, Corinth was familiar with such scenes.

corinthdeposition
Lovis Corinth (1858–1925), The Deposition (1895), oil on canvas, 95 × 102 cm, Wallraf-Richartz-Museum, Cologne. Wikipedia Commons.

The Deposition (Descent from the Cross) (1895) was one of his major paintings from this time in Munich, and won a gold medal when exhibited in the Glaspalast in Munich that year. It shows the traditional station of the cross commemorating the lowering of the dead body of Christ from the cross, attended by Joseph of Arimathea and Mary Magdalene.

This work is a thoroughly modern approach to its traditional theme, in its framing, composition, and faces. Its close-in cropped view suggests the influence of photography, and the faces shown appear contemporary and not in the least historic. These combine to give it the immediacy of a current event, rather than something that happened almost two millennia ago. Corinth returned to the subject of the Deposition, and the theme of the Crucifixion, in many of his later paintings.

corinthautumnflowers
Lovis Corinth (1858–1925), Autumn Flowers (1895), oil on canvas, 120 × 70 cm, Private collection. Wikipedia Commons.

Autumn Flowers (1895) is a delightful full-figure portrait of a girl, her dress held out in front of her to carry her collection of flowers, which also decorate her hair and the background.

corinthforest

A Forest. Flooding on Lake Starnberg (1896) was one of the landscapes that he painted in the countryside near Dachau, and shows a flooded stand of birch trees at the edge of the lake, probably in the spring.

corinthbacchanale1897
Lovis Corinth (1858–1925), Bacchanale (1896), oil on canvas, 117 × 204 cm, Kunstmuseum Gelsenkirchen, Gelsenkirchen. Wikipedia Commons.

Bacchanale (1896) is the first of his series of paintings of the wild and licentious antics of worshippers of Bacchus. These provided the opportunity for him to compose some of his many studies of nudes into grander paintings, although this one is non-narrative.

corinthbutchers
Lovis Corinth (1858–1925) Butchers in Schäftlarn on the Isar (1897), oil on canvas, 70 × 87 cm, Kunsthalle Bremen, Bremen. Wikipedia Commons.

He returned to the theme of meat and animal carcasses in his Butchers in Schäftlarn on the Isar (1897), painted in this Bavarian town not far from Munich.

corinthfrauleinheck
Lovis Corinth (1858–1925), Fräulein Heck (in a Boat on the Starnberger See) (1897), oil on canvas, 59 × 86 cm, Private collection. Wikipedia Commons.

He painted this portrait of Fräulein Heck (in a Boat on the Starnberger See) (1897) on this picturesque lake near Dachau. This form of portrait, of a woman carrying a parasol in a boat, was popular at the time.

corinthnudewoman1897
Lovis Corinth (1858–1925), Nude Woman (1897), oil on canvas, 100 × 73 cm, Private collection. Wikipedia Commons.

Corinth continued to paint figure studies, such as his Nude Woman (1897), for their value in his more substantial figurative works.

corinthtemptationsaintanthony
Lovis Corinth (1858–1925), The Temptation of Saint Anthony (1897), oil on canvas, 88 × 107 cm, Bayerische Staatsgemäldesammlungen, Munich. Wikipedia Commons.

The Temptation of Saint Anthony (1897) visits another traditional religious theme, well-known for encouraging inventive and sometimes highly imaginative paintings. As with his earlier Deposition, Corinth shows the saint surrounded by modern temptations, in a real style. There’s a wealth of detail here, from the bright eyes of the owl in the top left corner, down to the sinister flick of the snake’s tongue at the lower right, demonstrating the history painter’s eye for detail and Corinth’s own Symbolist leanings in narrative.

corinththewitches
Lovis Corinth (1858–1925), The Witches (1897), oil on canvas, 94 × 120 cm, Private collection. Wikipedia Commons.

The Witches (1897) is more subtle than it looks, as this isn’t a depiction of sensuous rites taking place in a coven. Instead, the women are preparing a younger woman to attend a masked ball. Their subject has just got out of the wooden tub in the foreground, has been dried off, and is about to don the fine clothes laid over the chair at the left, including the black mask.

Although Corinth undoubtedly drank more than his fair share of red wine and champagne while painting in Munich, his technique and style were maturing fast. The best of his paintings from this period are the equal of better-known works from later in his career. The stage was set for his first truly momentous painting.

How to search successfully in Spotlight: Query languages

Although the great majority use GUI search tools provided in the Global Spotlight menu, Finder Find windows, and in-app Core Spotlight, macOS also provides access using query languages. This article takes a brief tour of those available in macOS. As with previous coverage, this doesn’t include third-party utilities such as HoudahSpot that provide their own interface to Spotlight searching, nor alternative search methods.

Search boxes

Search boxes provided by both Global Spotlight and Local Spotlight can accept a simple form of query language, for example
name:"target"*cdw
which also works with filename:, and performs the equivalent of the Matches operator in a Find window. These use English terms for the attributes to be used, like name and filename, including some of those listed here for Core Spotlight. However, limited information is available and this doesn’t appear to be extensive enough to use at scale. Operators available are also limited within those listed for Core Spotlight.

Modifiers available in current macOS include

  • c for case-insensitivity,
  • d to ignore diacritics such as accents,
  • w to match on word boundaries, as marked by space, underscore _, hyphen – and changes of case used in CamelCase.

The asterisk * can be used as a wildcard to match substrings, and the backslash \ acts as an escape character, for example \" meaning a ” literal. In theory, simple predicates can be combined using && as AND, and || as OR.

In practice, getting these to work is tricky, and rarely worth the effort of trying.

Raw queries

One of the least-used attributes available in search bars in the Find window enables the use of what are termed raw queries. Confusingly, these use different names for attributes, such as kMDItemDisplayName instead of name. Otherwise these are more reliable than those used in search boxes. For example, when searching for the string target,
kMDItemDisplayName = "*target*"
is the equivalent of Contains, and
kMDItemDisplayName = "target*"w
appears functionally identical to Matches.

These appear to be an option of last resort, and need documentation.

mdfind

This command tool provides the most complete access to the central Spotlight Query Language, which defies abbreviation to SQL. In addition, it also supports a direct form that searches for matching file names only, using
mdfind -name "target"
to find the word target in filenames.

Unfortunately, although Spotlight Query Strings are predicates, they aren’t the same as NSPredicates used elsewhere within macOS. One of the most obvious differences is that Spotlight’s modifiers are appended to the value, not the operator, as they are when using search predicates in the log command, for example.

Query strings take the general form
attribute operator value[modifiers]
where

  • attribute is a kMD… name defined as a metadata attribute key,
  • operator can take a formal version such as ==, or may be abbreviated to just =, which appear to be identical in effect,
  • value can be a string containing wildcards or escapes, or those detailed for special cases such as numbers and dates,
  • modifiers include those given above.

Simple examples are
mdfind "kMDItemDisplayName = '*target*'"
or
mdfind "kMDItemDisplayName == '*target*'"

Apple’s current list of common metadata attribute keys is given here. Otherwise, documentation is old if not ancient, and there are obvious differences from current Spotlight and mdfind, such as the expanded list of modifiers.

File metadata queries are explained here, with an apparently duplicated version here. File metadata attributes are documented here, and a general account of predicates is here.

Saved Search Queries

On the face of it, one way to become familiar with and to develop query strings for use in mdfind might be to set them up in a Find window, save that and use the query string within it for your own. Although this can be helpful, queries in saved search files often use attributes not accessible to mdfind. For example, entering the string target in the search box setting a search bar to Kind is Image All is represented by the query
(((** = "target*"cdw)) && (_kMDItemGroupId = 13))
where the second attribute is an internal form of kMDItemKind.

However, this quickly runs into difficulties, as values of _kMDItemGroupId don’t appear to be documented, and substituting that with an alternative such as
kMDItemKind = "public.image"
fails silently.

Conclusions

  • Spotlight query strings take several forms, none of them well-documented.
  • Queries provided in Saved Search are of limited use, and are only likely to confuse.
  • For occasional use, they are usually frustrating.
  • For frequent use, third-party alternatives are more consistent and much better documented.

Interiors by Design: Church

Until well into the twentieth century, many of the people across Europe and North America spent time in church. For most communities, a local church was its centre, where everyone underwent their rites of passage from christening to funeral. Church registers recorded those events, and are now a rich source of information for genealogists and historians. Relatively few painters seem to have recorded the interiors of churches, though. Here are some examples.

frithmarriageprincewales
William Powell Frith (1819–1909), Marriage of the Prince of Wales, 10 March 1863 (1865), oil, further details not known. Wikimedia Commons.

Royal weddings were full of pageantry, as shown in William Frith’s painting of the Marriage of the Prince of Wales, 10 March 1863, completed in 1865. This took place under the watchful eye of the groom’s mother, Queen Victoria (on the balcony at the upper right), who seems to be attracting as much attention as the wedding in progress below her. The groom was to become King Edward VII on the death of the Queen; his bride was Alexandra of Denmark, who was only eighteen at the time. The ceremony took place in Saint George’s Chapel in Windsor Castle, which must be one of the grandest chapels in Britain.

fortunyspanishwedding
Marià Fortuny (1838–1874), The Spanish Wedding (1870), oil on wood, 60 x 93.5 cm, Museu Nacional d’Art de Catalunya, Barcelona, Spain. Wikimedia Commons.

Marià Fortuny painted this intricately detailed view of a contrasting Spanish Wedding in 1870. The scene is the interior of a sacristy, where a wedding party is going through the administrative procedures of the marriage ceremony. The groom is bent over a table, signing a document, while the bride behind him (holding a fan) is talking to her mother. The rest of the wedding party waits patiently, but a woman at the back of the small group turns towards a penitent, who stands to the right of the group. He carries an effigy of the soul burning in flames, hardly appropriate for the occasion.

Elizabeth Nourse (1859–1938), The Church of Saint Francis of Assisi (1890), oil on canvas, 47 x 61 cm, Private collection. The Athenaeum.

Elizabeth Nourse was born into a Catholic family, and appears to have remained a devout believer all her life. In 1890 she seems to have visited central Italy, where she painted the superb frescoes in the Papal Basilica of Saint Francis of Assisi, in The Church of Saint Francis of Assisi.

helleusaintdenis
Paul César Helleu (1859–1927), The Interior of the Abbey Church of Saint Denis (c 1891), oil on canvas, dimensions not known, The Isabella Stewart Gardner Museum, Boston, MA. The Athenaeum.

Paul César Helleu’s Interior of the Basilica of Saint-Denis (c 1891) is an example of his interest in churches and their stained glass, which included Reims Cathedral. The Basilica of Saint-Denis was the burial place for almost every French king between the tenth and eighteenth centuries, and now lies within the north of the city of Paris, although Saint-Denis was formerly its own city. The window shown is that of the north transept, featuring the tree of Jesse; a south transept rose shows the Creation.

It was the Norwegian painter Harriet Backer who took greatest interest in church interiors.

backerinngangskoner
Harriet Backer (1845–1932), Inngangskoner (Churching) (1892), media not known, 90.5 x 112.5 cm, Private collection. Wikimedia Commons.

Backer’s Churching (1892) shows a traditional ceremony in which a woman who has just completed the confinement following the birth of her child is received back at church, where she gives thanks for the survival of her baby and herself, and prays for their continuing health. This is believed to show the sacristy to the left of the altar in Tanum Kirke, in Bærum, Norway.

Harriet Backer (1845–1932), Barnedåp i Tanum Kirke (Christening in Tanum Church) (1892), oil on canvas, 109 x 142 cm, Nasjonalgalleriet, Oslo. Wikimedia Commons.

The next event in the life of mother and baby is shown in Backer’s Christening in Tanum Church (1892), one of her most sophisticated and greatest paintings which must be among the finest paintings in Post-Impressionism.

This looks both outward and inward. The left of the canvas takes the eye deep, through the heavy wooden church door to the outside world, where a mother is bringing her child in for infant baptism. The rich green light of that outside world colours that door and inner wood panelling, and the floorboards and perspective projection bring the baptismal party in. At the right, two women are sat in an enclosed stall waiting for the arrival of the baptismal party. One has turned and partly opened the door to their stall in her effort to look out and see the party enter church.

backeruvdal
Harriet Backer (1845–1932), Uvdal Stave Church (1909), media not known, 115 x 135 cm, location not known. Wikimedia Commons.

Of the many later paintings she made of church interiors, the finest must be Uvdal Stave Church (1909). Stave churches were once numerous throughout Europe, but are now only common in rural Norway. Their construction is based on high internal posts (staves) giving them a characteristic tall, peaked appearance. Uvdal is a particularly good example, dating from around 1168. As with many old churches, its interior has been extensively painted and decorated, and this has been allowed to remain, unlike many painted churches in Britain which suffered removal of all such decoration.

Backer’s richly-coloured view of the interior of the church is lit from windows behind its pulpit, throwing the brightest light on the altar. The walls and ceiling are covered with images and decorations, which she sketches in, manipulating the level of detail to control their distraction. Slightly to the left of centre the main stave is decorated with rich blues, divides the canvas, but affords us the view up to the brightly lit altar. To the left of the stave a woman, dressed in her Sunday finest, sits reading outside the stalls.

Colin Campbell Cooper (1856–1937), The Interior of Lincoln Cathedral (c 1905), other details not known. Wikimedia Commons.

Known now for his pioneering paintings of New York skyscrapers, Colin Campbell Cooper also visited Britain and painted The Interior of Lincoln Cathedral in about 1905. This shows the area of the organ in this English cathedral dating from 1088. The organ shown had only recently been installed by the classical organ-builder Henry Willis. Cooper captures particularly well the lofty and distinctive vaulted ceiling and incoming shafts of light.

Léon Augustin Lhermitte (1844–1925), The Prayer, the Church of Saint-Bonnet (before 1920), pastel on stretched paper, 49.8 × 57.5 cm, location not known. Wikimedia Commons.

Léon Augustin Lhermitte had painted a few religious works earlier in his career, but his late pastel of The Prayer, the Church of Saint-Bonnet (before 1920) is probably the most moving. Odilon Redon and other contemporary pastellists also depicted stained glass windows to great effect.

rochegrosseinteriorofthecathedral
Georges Rochegrosse (1859–1938), Interior of the Cathedral of Reims in Flames (1915), oil on canvas, 100 x 73 cm, Musée des beaux-arts, Reims, France. By G.Garitan, via Wikimedia Commons.

At the start of the First World War, the cathedral of Notre-Dame de Reims, where the Kings of France were once crowned, had been commissioned as a hospital and demilitarised. German shells hit the cathedral during opening engagements on 20 September 1914, setting alight scaffolding, and destroying some of the stonework. The fire spread through woodwork, melting the lead on the roof, and destroying the bishop’s palace. The French accused the Germans of the deliberate destruction of part of its national and cultural heritage.

Georges Rochegrosse’s Interior of the Cathedral of Reims in Flames (1915) casts this in a curious combination of the physical reality of the shattered masonry and fire, the ancient glory of the cathedral’s stained glass, and an Arthurian figure (possibly the Madonna herself) reaching up to seek divine intervention.

LogUI build 58 reads and writes JSON, and more

Until now, LogUI has largely been an interactive log browser, and only able to export log excerpts in Rich Text format. This new build adds three tools to greatly increase its usefulness, as it can now write log excerpts in JSON format, open saved files, and filter out unwanted log entries. To give a simple example, this screenshot shows a log extract that has been reduced to entries made only by LaunchServices, converted from JSON to CSV, and imported into Numbers.

There are three new tools in LogUI’s toolbar.

From the left:

  • Get Log fetches and displays log entries specified by the current log settings, as before.
  • Read JSON opens a dialog for you select a LogUI JSON file, and loads its log entries into the window, replacing its current contents.
  • Gloss opens the Gloss window with message text from selected log entries, enabling you to use Writing Tools and other aids, as before.
  • Reduce applies the current search to current log entries. This removes all entries that are excluded by that search, so reducing the number of log entries. If you want to keep a copy of the unreduced log, save it as a JSON file before reduction.
  • Save JSON opens a dialog for you to save the current log records to a new LogUI JSON file. This has the type co.eclecticlight.loguilog, and the extension .logui, and can be used as a regular JSON export with other apps capable of importing JSON format.
  • Save RTF saves the current log excerpt as a Rich Text Format file, using the same colour conventions, as before.

You can now filter log entries in several ways, one at a time or all together:

  • You can apply a predicate to determine which log entries are fetched in the first place, perhaps limiting them to one or two subsystems.
  • You can search for subsystems, sender or process names, or contents of messages in the search box.
  • When you have filtered the displayed log entries to those that you want, you can reduce the excerpt to include just those, and save that excerpt.
  • You can then open the saved, reduced excerpt and use further searches to navigate and analyse those entries.

As we’ve recently been discussing different types of Spotlight search, I should perhaps explain that LogUI’s search isn’t word-based, simply finds matching sequences of characters, and doesn’t support regex or wild card search. If you search for the characters arb, then it will find them in the words nearby and arbitrary, but not in arabesque.

There are two current limitations with these new JSON documents. If you double-click one, LogUI should launch automatically and will then open a new window, but won’t load that document into the window, as that part of its internal wiring isn’t yet complete. The same also happens if you try dropping a document onto the app. I did hope to have drag and drop working in this release, but the resulting code proved too complex for the Swift compiler in Xcode to negotiate, so that will also wait for a future build.

LogUI 1.0 build 58 is now available from here: logui158
and from its Product Page.

This is likely to be the last update for a couple of weeks, as I expect I’ll be immersed in WWDC and its fallout for much of the next fortnight. My outstanding tasks are:

  • complete the predicate editor in Settings;
  • add support for opening documents from the Finder;
  • add drag and drop support.

I’m also thinking about additional search/filter support, and whether a more compact binary document format might be a worthwhile alternative for large log excerpts.

As ever, I value your comments and suggestions.

Reading Visual Art: 215 Wrestling

Long before its commercialisation as entertainment, wrestling was an important form of hand-to-hand combat, developed into a sport by the ancient Greeks, and a feature of Spartan military training and classical games, the origin of the Olympics. Although never a popular theme for paintings, wrestling has narrative significance, as shown in this small selection of examples.

In ancient myth, Achelous and the hero Hercules (Heracles) engaged in a wrestling match, during which Achelous transformed himself into a bull, Hercules wrenched one of his horns off, and that became the cornucopia, horn of plenty.

Cornelis Cornelisz. van Haarlem’s painting of Hercules and Achelous, probably from around 1590, shows a late stage in their wrestling, with Achelous the bull brought to the ground by Hercules, who is here trying to twist his horns off.

Guido Reni’s Hercules and Achelous (1617-21) opts for a more conventional wrestling match, with Achelous still in human form.

Noël Coypel (1628–1707), Hercules Fighting Achelous (c 1667-69), oil on canvas, 211 × 211 cm, Palais des Beaux-Arts de Lille, Lille, France. Wikimedia Commons.

Noël Coypel, father of the better-known history painter Antoine Coypel, painted Hercules Fighting Achelous in about 1667-69. This too opts to show the pair during the first phase of their fight. In addition to wearing his lionskin, Hercules wields his fearsome club, although Ovid doesn’t refer to its use on this occasion.

Another ancient narrative involving wrestling is told in the Old Testament book of Genesis, chapter 32 verses 22-31, when Jacob is on his journey to Canaan:

And he rose up that night, and took his two wives, and his two womenservants, and his eleven sons, and passed over the ford Jabbok. And he took them, and sent them over the brook, and sent over that he had.

And Jacob was left alone; and there wrestled a man with him until the breaking of the day. And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob’s thigh was out of joint, as he wrestled with him. And he said, “Let me go, for the day breaketh.” And he said, “I will not let thee go, except thou bless me.” And he said unto him, “What is thy name?” And he said, “Jacob.”

And he said, “Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed.” And Jacob asked him, and said, “Tell me, I pray thee, thy name.” And he said, “Wherefore is it that thou dost ask after my name?” And he blessed him there.

And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved. And as he passed over Peniel the sun rose upon him, and he halted upon his thigh.

Eugène Delacroix’s large and magnificent painting of Jacob Wrestling with the Angel (1854-61) shows the moment the stranger touches Jacob on the tendon of his thigh and renders him helpless (detail below). To the right are flocks of sheep with Jacob’s shepherds driving them on horses and camels.

Jacob and the Angel (1874-78) is Gustave Moreau’s finished oil painting showing the young Jacob wrestling heroically with the invisible power that is God, the angel standing nonchalantly by.

The other well-known story of wrestling in ancient times is that of Samson and the lion. When he was young, Samson fell in love with a Philistine woman. Despite the objections of his parents, he decided to marry her, and travelled to make his proposal. On that journey, he was attacked by a lion, which he wrestled with, and tore apart, thanks to the strength given him by God. He told no one about that episode, and when he was on his way to his wedding, he came across the carcass of that lion. In its body was a bees’ nest containing honey. This inspired the line ‘out of strength came forth sweetness’, long used as a motto on tins of golden syrup.

During Samson’s wedding feast, he posed his thirty Philistine groomsmen a riddle based on his encounters with that lion: Out of the eater came something to eat. Out of the strong came something sweet. They failed to guess the answer, which Samson only revealed after they had threatened him, and his bride had begged him to do so.

Franz von Stuck’s Samson (1891) is meticulously labelled, and shows the immensely strong Israelite warrior fighting with the huge lion.

During the nineteenth century, folk and Greco-Roman wrestling developed into a sport popular enough by the time of the first modern Olympic Games in 1896 to qualify for inclusion there.

Gustave Courbet’s Wrestlers from 1853 shows two well-muscled men grappling with one another to the entertainment of distant crowds. Unusually for his figurative paintings of the time, Courbet makes it clear that the wrestlers were painted in the studio and appear almost pasted into the setting, without integration of their shadows, for example, and his perspective looks slightly askew.

Frédéric Bazille started painting Summer Scene, also known as Bathers, during the summer of 1869 when he was on holiday in Montpellier. He had already made a series of compositional studies, from as early as February that year, but when he was working on the canvas, he didn’t find it easy going, and complained of headaches and other pains.

He eventually opted for a composition based on strong diagonals, with the bathers in the foreground in shade, while the two wrestlers in the distance are lit by sunshine. The landscape background was painted from the hot green mixture of grass with birch and pine trees, typical of the banks of the River Lez, near Montpellier. He completed this painting in early 1870, and it was accepted for the Salon of that year, where it was well-received by the critics.

Twenty years later, the Naturalist Émile Friant painted The Fight, or Wrestling, (1889), in a rural scene from near Nancy, France. A group of boys have gathered by a small river, and look ready to enter the water. Two are in the foreground, on the opposite bank, engaged in a fight. They are strained over, as one holds the other in a wrestling lock, with their legs spread wide apart and tensed.

Prepare your Mac for safe disposal

In the next few months, many of us will replace our Macs, and pass on our old ones to relatives, purchasers, or for recycling. This article explains how best to prepare your Mac so that you don’t unintentionally give away anything sensitive to its next owner, or lose anything in the process.

Back up and sign out

Your first steps should ensure that your Mac doesn’t take with it anything that you might miss. That means making at least one full backup, and ensuring you have stored additional copies of important documents in archives.

One store you might forget are its keychains, that could contain old passwords that you might need to recover in the future. While you’re most likely keeping current passwords in the keychain shared in iCloud, older ones might remain, particularly in your old Mac’s login keychain. That should be in its backup, but keeping another copy is wise, and will include any security certificates you might not have used recently.

Next come third-party apps and subscriptions that need to be signed out or transferred. Check carefully through the Applications folder to ensure that you haven’t forgotten any that are still valid. Among those is the need to deauthorise your old Mac for Apple media, something you should do using one of its media apps such as Music or TV, or iTunes if it’s running an older version of macOS.

If it’s an Intel Mac and its firmware password has been enabled, start it up in Recovery and disable that before going any further.

T2 and Apple silicon

If it’s an Intel Mac with a T2 chip, or an Apple silicon Mac, your task is almost complete, as all that’s required now is to Erase All Content and Settings (EACAS).

There is one important exception to this, if you added any more containers or volumes to its internal storage. They aren’t protected by FileVault and the Secure Enclave, so need to be erased separately before using EACAS. This is most secure if those extra volumes or containers were also encrypted, but as you’re about to use EACAS, that should make it well nigh impossible for anyone to piece together the remains of your extra volumes on its SSD.

Start EACAS from System Settings > General > Transfer or Reset > Erase All Content and Settings…. In older versions of macOS that still use System Preferences, open them and it’s offered as a command in the app menu there. Once that’s done, all that remains is to remove that Mac from your account in the Apple Account pane on another Mac or device.

eacas

EACAS handles all the signing out that’s required, and disables Find My Mac and Activation Lock for you. But most importantly it ensures that no one can access the contents of its Data volume, by destroying the encryption keys used to encrypt that volume. Without those keys, it’s practically impossible for anyone to break that encryption and recover any of the protected data.

If your old Mac is going for recycling, you might like to open it up and physically destroy its internal storage, just to be safe.

Intel Macs without T2

EACAS is only available in Macs with T2 or Apple silicon chips. If your Mac doesn’t have either of those you’ll need to perform each step manually, going through

  1. disable Find My Mac and Activation Lock
  2. sign out of iCloud
  3. sign out of iMessage
  4. reset NVRAM
  5. unpair all Bluetooth devices
  6. erase the Mac and, if you’re passing it on to someone else, install macOS
  7. remove that Mac from your account in Apple ID settings.

The biggest challenge is how to erase its storage securely. If it’s going for recycling, you can open it up and physically disrupt its storage, but when you’re passing that Mac on you obviously can’t do that.

If its internal storage is a hard disk, or Fusion Drive, the traditional solution is to perform a Secure Erase using Disk Utility. However, Apple has removed that from Sequoia, so you’ll need to create an external bootable disk with Sonoma or earlier to enable you to do that.

Secure Erase neither works nor is it wise when trying to clean an internal SSD, though. The most practical solution is to turn FileVault on, leave the Mac to complete encrypting the whole of its Data volume, then start it up from an external bootable disk and erase the internal SSD from there.

.AppleSetupDone

In the past, some have recommended deleting the .AppleSetupDone file in /var/db/, which then caused the Setup Assistant to launch when that Mac was next started up, to create a new local user. For a Mac that’s going to be used by someone else, this has never been a wise move, and Apple has stopped that from working in macOS Sonoma 14.0 and later. It’s far better to use EACAS to reset that Mac, then Setup Assistant will run when it next starts up.

Checklist

  • Back up
  • Make additional copies of important documents, keychain(s)
  • Sign out from or transfer third-party apps
  • Deauthorise for Apple media
  • Disable firmware password (Intel)
  • Delete any extra containers or volumes if they’ve been created on internal storage.
  • Erase All Content and Settings (T2, Apple silicon), or manual list above
  • Remove from Apple Account
  • Physically destroy internal storage (if recycling).

Modern Stories of Lovis Corinth: 1880-90

Almost a century ago, on 17 July 1925, one of the greatest German painters of modern times died. From the early 1880s until then, Lovis Corinth painted prolifically in every genre from classical myths to landscapes. At the height of his career in December 1911 he almost died as the result of a major stroke, but with the devoted support of his wife he learned to paint again. In this series I look at a selection of his paintings, and how they changed over the course of more than forty years.

He was born Franz Heinrich Louis Corinth in the village of Tapiau, in what was then the northern part of East Prussia, and is now the town of Gvardeysk near Kaliningrad, Russia. He was schooled in the city of Königsberg (now Kaliningrad), and soon resolved to be an artist. He started attending the Academy of Fine Arts in Königsberg in 1876, where he decided that he wanted to be a history painter, and concentrated on painting the figure.

On the advice of his teachers in Königsberg, Corinth moved to Munich in the spring of 1880, where he initially studied with Franz von Defregger. At that time, Munich almost rivalled Paris as a progressive centre for the arts, and had been the preference of William Merritt Chase, who had left Munich only two years previously. Corinth learned both traditional and modern techniques of oil painting in the studio of Ludwig von Löfftz, where he concentrated on painting from life.

Even his earliest figures, such as his Crucified Thief from 1883, were powerful, and showed influence from the Dutch Masters.

Like William Merritt Chase, Corinth was particularly fond of the work of Van Dyck and Frans Hals, as revealed in his portrait of Laughing Girl (1883).

Black Othello (1884) was probably his first success, and was exhibited to acclaim in Königsberg. That same year another of his paintings won a bronze medal in London, and was exhibited at the Salon in Paris the following year.

Corinth completed his training in Munich in 1884, and moved to Antwerp for a few months, before he settled in Paris that autumn. There he enrolled in the Académie Julian, where he studied under Bouguereau and Robert-Fleury, and concentrated on female nudes and building his repertoire of mythological scenes. He was influenced by the 1885 retrospective exhibition of the works of Jules Bastien-Lepage, who had died suddenly in 1884, and that aided a move towards greater naturalism.

Examples of his paintings from life from his time in Paris include his study of a Nude Girl (1886) above, and below of a Sitting Female Nude from the same year.

In 1886 he visited Germany, and painted some landscapes and portraits en plein air on the Baltic coast near Kiel. When he returned to Paris that autumn, he was becoming increasingly frustrated by his inability to achieve success at the Salon. He only had two paintings accepted there, in 1885 and 1887, and neither had achieved critical success or a medal. He left Paris, and joined the Nasser Lappen (‘Wet Rags’) group in Berlin for a while, trying to progress his history painting. It was then that he painted his first self-portrait.

In 1888, he returned to Königsberg, adopted the name of Lovis Corinth, and started to find form at last. Woman Reading shows his early style maturing well, with its subtle use of light.

His father, who had been a successful tanner, fell ill, prompting Corinth’s sensitive painting of his final illness in Father, Franz Heinrich Corinth, in Hospital (1888). After his father died early the following year, Corinth became financially independent, and set up a proper studio in Königsberg at last.

He painted portraits, including this of Franz Lilienthal (1889), another East Prussian student at the Académie Julian. That same year he was inspired by an exhibition of the work of contemporary German painters including von Lenbach, Böcklin and von Uhde, as a result of which he finally obtained an honourable mention at the Salon in 1890.

That year he painted one of his most accomplished early portraits, Innocentia (1890), and made his first attempts at a history painting of a popular narrative.

Corinth painted two versions of Susanna Bathing (Susanna and the Elders) in 1890: that above, now in the Museum Folkwang, and that below, thought to be in a private collection.

The story of Susanna (or Shoshana) and the Elders is told in the Old Testament book of Daniel, chapter 13, and centres on voyeurism, blackmail, and justice. Susanna was a beautiful married woman who was bathing in her garden one afternoon, having dismissed her servants. Two lustful elders spied on her, and as she returned to her house they stopped her, and threatened that, unless she agreed to have sex with them, they would claim that she had met her lover in the garden. Being virtuous, Susanna refused their blackmail, and was promptly arrested, charged with promiscuity, and awaited her execution.

The young prophet Daniel interrupted the process, demanding that the elders should be properly questioned before such a severe penalty was applied. When questioned individually, the two elders gave different accounts, most notably in the type of tree under which Susanna allegedly met her lover. The accusations were thus revealed to be false, Susanna was acquitted of the charge, and the two elders were executed instead.

From the early Renaissance, this has been a popular story in painting, almost universally depicted as a nude bather being spied on by two nasty old men. As narrative, this is weak, as the crux is the conflicting evidence of the elders, which is much harder to paint, and is usually just an excuse to paint a female nude with some gratuitous anti-semitism.

Corinth shows what had become a fairly traditional version, in which Susanna is seen in the flesh but not under any tree in the garden: she is instead being spied on from behind a curtain, with only one of the two elders clearly visible.

Of his two versions, that in the Museum Folkwang appears the less finished, but both emphasise Susanna’s nakedness with her clothes, and add refinements by way of her discarded jewellery and a flower from her hair. Her figure reflects the effort that Corinth had put into life studies, and makes his simple composition successful.
