Armour, either in the form of plates of metal or chain mail with its many interlocked rings, is the primary attribute and symbol of the warrior. As such, several of the classical deities are often depicted wearing armour.

Peter Paul Rubens painted The Triumph of Victory in about 1614 for the Antwerp Guild of St George, its organisation of archers. Mars in his short suit of black armour dominates, his bloody sword resting on the thigh of Victoria, the personification of victory. She reaches over to place a wreath of oak or laurel on Mars, and holds a staff in her left hand. At the right, Mars is being passed the bundle of crossbow bolts that make up the attribute of Concord. Under the feet of Mars are the bodies of Rebellion, in the foreground, who still holds his torch, and Discord, on whose cheek a snake is crawling. The bound figure resting against the left knee of Mars is Barbarism.

Jacob Jordaens’ finished version of an original sketch by Rubens now known as The Golden Apple of Discord (1633) shows the wedding feast of the deities where Eris (Discord) makes her gift of the golden apple to set up the Judgement of Paris, leading to the Trojan War. At the left, Athena/Minerva, wearing her plumed helmet and a suit of ornate plate armour, reaches forward for that apple.

Just to confuse, the Roman goddess of war, Bellona (Greek Enyo), is also shown in or with armour by convention.

Peter Paul Rubens’ undated Portrait of Marie de’ Medici as Bellona shows her in the midst of cannon, arms and armour, with an exuberantly decorated helmet, a sceptre and a statue of a winged woman.

Armour inevitably plays a role in some of the events reported during the war against Troy. After his close friend Patroclus had been killed while wearing the armour of Achilles, he demanded a fresh suit made by Vulcan/Hephaestus before he would return to engage in battle.

Anthony van Dyck’s Thetis Receiving the Weapons of Achilles from Hephaestus from about 1630-32 shows the scene when Thetis is collecting her son’s new armour from Hephaestus, at the left.

Benjamin West’s Thetis Bringing the Armour to Achilles from 1804 shows the Greek warrior being presented with the armour and helmet by his mother Thetis.

When Achilles is killed in battle, in accordance with warrior tradition, his armour was handed on to the next in line, who could have been either Ajax or Odysseus.

Leonaert Bramer’s small painting on copper of The Quarrel between Ajax and Odysseus was made between about 1625-30. The pair stand in their armour, next to tents pitched at the foot of Troy’s mighty walls. At their feet is the armour of Achilles, and all around them are Greek warriors, some in exotic dress to suggest more distant origins.

Armour also leaked through into Christian religious paintings.

Lucas Cranach the Younger sets The Conversion of Saul (1549) in mediaeval northern Europe, with Paul and his party riding knightly chargers in their armour. Paul’s horse has fallen to the ground, with Paul still in the saddle rather than prostrate on the ground. Paul holds his hands up and looks to the heavens, where the figure of Christ is seen in a break in the clouds at the top left corner.

It was the young French martyr Joan of Arc, though, who is most often depicted wearing armour.

JAD Ingres painted Joan of Arc at the Coronation of Charles VII, in Reims Cathedral (1854). She stands close to the crown, resplendent in full armour and holding a standard, the two-pointed oriflamme embroidered for her by the women of Orléans, in her right hand.

The second scene in Jules Eugène Lenepveu’s Joan of Arc Murals (1886-90) shows Joan leading the French forces against the English, who were laying siege to the French city of Orléans. There had been controversy in Joan’s trial as to whether she had used weapons against the English; Lenepveu hedges here, showing her holding a sword in her right hand, but brandishing the Dauphin’s standard to rally the French, in the role that she described of herself. She’s wearing a suit of plate armour, which she was provided with in preparation for this operation. As this would have been designed to fit a man, this was part of the case against her for ‘cross-dressing’ in men’s clothes.

Lovis Corinth is one of several major painters who acquired themselves a suit of armour. This featured in two symbolic paintings made before and after the First World War.

When war broke out on 28 July 1914, Lovis Corinth and most of the other artists in Berlin shared an enthusiastic patriotism that initially gave them a buoyant optimism. He expressed this openly in his In Defence of Weapons from 1915.

Armour Parts in the Studio is Corinth’s summary of Germany’s defeat in 1918. The suit of armour is now empty, broken apart, and cast on the floor of his studio.

Blue pigments used in painting include some of the oldest used by man, and others that led the change to modern synthetic pigments driven by the arrival of chemistry in the eighteenth century. This weekend I look at two examples, today the queen of pigments, ultramarine, and tomorrow the first synthetic chemical, Prussian blue.

Originally made by crushing and grinding the semi-precious stone lapis lazuli, the cost of ultramarine has exceeded that of gold. Seen in paintings, it produces a rich slightly reddish blue which stands the test of time, as distinctive and effective today as when it was first used. And its use has a history of unmasking fakes and forgeries.

The sole source of lapis lazuli in Europe and the West were quarries in Badakshan, described by Marco Polo and now in Afghanistan. It appears that wall paintings made around 507-554 CE adjacent to the great Buddahs of Bamiyan were the first to have used the mineral as a pigment. It was then used in early Persian miniatures, and in early Chinese and Indian paintings too. Tragically, these wall paintings in Bamiyan, Afghanistan, were damaged by the Taliban in 2001 when the two statues were destroyed, and their restoration has made little progress since.

The powdered pigment had made its way, first along the Silk Road, then by sea, to traders in Venice by about 1300. By the Renaissance, it was established as one of the most important and precious of all the pigments used in European art.

Because of its beauty and high cost, ultramarine blue was used for the robes of Jesus Christ and the Virgin Mary. Duccio’s panels from the Maestà Predella, including this of The Healing of the Man born Blind, show this tradition in its earliest years, around 1307-11. As a pigment, it proved practical in egg tempera as here, and in oils, watercolour, and fresco.

Ultramarine blue has been found in the van Eyck brothers’ Ghent Altarpiece from about 1432 (above), and particularly in its most famous panel, The Mystic Lamb, below.

Sandro Botticelli’s early tempera on panel painting Adoration of the Kings from about 1470, apparently made with Filippino Lippi, shows two different blue colours and purple. He painted the purple with an opaque underpainting of lead white tinted with a red lake derived from madder, to create pink. That was then glazed with quite coarse particles of ultramarine blue, so the pigment was thinly dispersed.

Peter Paul Rubens used ultramarine blue widely in his magnificent triptych now in Antwerp Cathedral. In its centre panel, Descent from the Cross (1612-14), it has been found combined with indigo and other pigments.

In van Dyck’s Charity from 1627-8, its most obvious use is in the blue cape, where ultramarine blue was painted over indigo, applied as both a tint and as a glaze over the top.

Visit any of the larger galleries with substantial collections of paintings made before 1700, and you will see works with drapery that I can only describe as arresting in the brilliance of their ultramarine blue. One stunning example in the National Gallery in London is Sassoferrato’s The Virgin in Prayer from 1640-50. The Virgin’s cloak looks as if it was painted only yesterday, and that colour makes you stop in your tracks and draws you into the painting, like no other pigment can.

Given its importance, and limited supply, considerable effort was devoted to ensuring that natural ultramarine blue was of the highest quality, and alternative sources were sought. Deposits in the Chilean Andes, and near Lake Baikal in Siberia, weren’t developed until the nineteenth century, and attempts to make synthetic ultramarine proved unsuccessful until 1828, when Jean Baptiste Guimet was awarded a prize of six thousand francs for his discovery. Almost simultaneously, C G Gmelin of Tübingen discovered a slightly different method.

Commercial production had started by 1830, and it became known as French ultramarine, to distinguish it from the natural pigment. Although almost identical in colour and performance, there are significant differences between natural and synthetic ultramarine when tested in the laboratory. This has enabled the examination of paintings to determine the source of their pigment, and has brought some surprises. These most often relate to later overpainting during restoration. For example, two areas of much later painting have been discovered in the van Eycks’ Ghent Altarpiece.

Examination of Édouard Manet’s Corner of a Café-Concert, from 1878-80, has shown that he used synthetic ultramarine in its blue passages, for example.

Pierre-Auguste Renoir’s The Umbrellas, from about 1881-86, uses synthetic ultramarine in a methodical fashion. The first stage in its painting used only cobalt blue, but in its second stage synthetic ultramarine was applied extensively.

Vincent van Gogh’s A Wheatfield, with Cypresses (1889) contains synthetic ultramarine in its deepest blues, and in some areas of green, although it’s unusual to find ultramarine mixed to form green. Before synthetic pigment became available, this would have been far too expensive a way of making any significant amount of green, but once much cheaper pigment came onto the market, that became more feasible, if still unusual.

The ability to distinguish synthetic ultramarine, which didn’t exist before about 1828, and the natural pigment has proved important in detecting some forgeries. Only the most ignorant would attempt to pass off a painting made with synthetic ultramarine as being very old, but a few fakes fell at that hurdle.

Han van Meegeren was far too knowledgeable and cunning to be caught so easily. He used natural ultramarine, for example when he sold The Men at Emmaus (1937) to the Museum Boijmans Van Beuningen as a Vermeer. What no one knew at the time was that his ultramarine looked genuine, but had been contaminated with a small amount of cobalt blue, which wasn’t discovered until 1803-04, and was first used as a pigment in 1806.

In 1960, the modern artist Yves Klein worked with the paint supplier Edouard Adam to ‘invent’ a paint he termed International Klein Blue (IKB). Although its formulation is a secret, it’s almost entirely synthetic ultramarine blue pigment in a polyvinyl acetate binder.

Like all the best queens, ultramarine blue has an unnerving habit of revealing the truth.
