Aeneas has been rowed through the Straits of Messina, avoiding the rock pinnacle that Scylla had been transformed into. From there he heads north-west until he meets a fierce northerly storm that blows him and his crew south to the city of Carthage, on the Libyan coast. Ovid breezes through what takes Virgil almost a whole book in the Aeneid, in a brief summary of the affair between Aeneas and Dido, Queen of Carthage. This ends with him abandoning her to fall upon the sword he had given her, and her body to be consumed on her funeral pyre.

Pierre-Narcisse Guérin’s Aeneas tells Dido the misfortunes of the City of Troy, painted in about 1815, is probably the standard work showing the beginnings of their romance. Unfortunately it doesn’t give any clues to its tragic outcome.

In about 1875, when Paul Cézanne was still experimenting with narrative genres, he first drew a compositional study, then painted Aeneas Meeting Dido at Carthage. The queen is at the left, surrounded by her court. The warrior figure of Aeneas stands to the right of centre, and to the right of him is the shrouded spectre of Aeneas’ wife, Creusa, who had been abandoned by Aeneas as the family fled the burning city of Troy.

Normally titled The Death of Dido, Tiepolo’s painting from 1757-70 shows an odd composite scene in which Aeneas, packed and ready to sail with his ship, watches on as Dido suffers the agony of their separation, lying on the bed of her funeral pyre. A portentous puff of black smoke has just risen to the left, although it’s surely far too early for anyone to think of setting the timbers alight.

Dido’s spectacular death is shown best in what is perhaps Henry Fuseli’s most conventional history painting, known simply as Dido (1781). Dido has just been abandoned by Aeneas, has mounted her funeral pyre, and is on the couch on which she and Aeneas made love. She then falls on the sword Aeneas had given her, and that rests, covered with her blood, beside her, its tip pointing up towards her right breast. Her sister Anna rushes in to embrace her during her dying moments, and Jupiter sends Iris (shown above, wielding a golden sickle) to release Dido’s spirit from her body. Already smoke seems to be rising up from the pyre, confirming visually to Aeneas that she has killed herself, as he sails away from Carthage.

After a close call with the Sirens, Aeneas reaches the land of the Cercopes, who had been transformed into apes by Jupiter because of their treachery. The ship continues to the north-west along the coast of Italy, passing Naples.

This has been shown only by those like Antonio Tempesta who engraved for illustrated editions of the Metamorphoses. Tempesta’s Jupiter Changing the Cercopians into Monkeys from around 1600 shows Jupiter at the right, accompanied as ever by his huge eagle, with the transformed monkeys.

Once past Naples, Aeneas and his crew land at Cumae to visit the Sibyl there in her cave. He needs her assistance to go to the underworld to speak to the ghost of his father Anchises. The Sibyl reassures Aeneas that he will achieve his goals, and to that end she takes him to Proserpine’s sacred glade. Finding a golden bough there, she tells Aeneas to break that from the tree. The two of them travel to the underworld bearing that golden bough, make contact with the ghost of Anchises, and return safely.

During their walk back, Aeneas thanks the Sibyl for her help and guidance, and offers to build a temple to her, assuming she is a goddess. The Sibyl points out that she is no goddess, and explains how she had once been offered immortality if she were to let the god Apollo take her virginity. When Apollo had invited her to wish for anything, she had pointed to a pile of sand, and asked to live as many years as there were grains, but forgot to wish for eternal youth to accompany that.

Apollo offered her eternal youth as well, but she declined and remained a virgin. After seven hundred years, with another three hundred still to go, she is well into old age, infirm, and steadily vanishing as her body wastes away until only her voice will remain. With that, the pair reach Cumae, and Aeneas sets sail.

This is depicted in one of Claude Lorrain’s most wonderful coastal landscapes, his Coast View with Apollo and the Cumaean Sibyl from about 1645-49. Although their figures are small, Apollo on the left is holding his lyre in his left arm, trying to persuade the seated Sibyl, to the right, to let him take her virginity. Around them are the ruins of classical buildings and a stand of tall trees, as the land drops away to an idealised view of the coast of Italy. In the small bay immediately below them are some ships, which may be a forward reference to Aeneas’ future visit, although that would have been seven centuries later according to the Sibyl’s account.

JMW Turner didn’t tackle the first part of this story until 1823, when he painted The Bay of Baiae, with Apollo and the Sibyl. His view appears to have been loosely based on Claude’s, but is set at Baiae, in the Bay of Naples. Apollo is again on the left, with his lyre, but the dark-haired Sibyl has adopted an odd kneeling position. She is holding some sand in the palm of her right hand, asking Apollo to grant her as many years of life as there are grains.

When Claude was painting his coastal view, François Perrier was painting a more conventional figurative account of Aeneas and the Cumaean Sibyl (c 1646). Aeneas, stood to the left of the incense burner, appears to be offering to burn incense in honour of the Sibyl, who stands at the right in front of her cave, and is just about to tell him her life-story. Behind Aeneas is a queue of people, including a king, bearing gifts and waiting to consult with the Sibyl. At the top left corner is a temple, and in the clouds above it the god Apollo, I believe.

JMW Turner’s first version of this later scene is thought to have been his first mythological painting, in about 1798. This second version, Lake Avernus: Aeneas and the Cumaean Sybil, dates from 1814 or 1815, and is both an improvement on the original and in better condition. True to the spirit of Claude’s landscape, this too is a mythological landscape showing the beautiful setting of Lake Avernus, near Pozzuoli, to the west of the city of Naples. In the distance are Baiae and the cliffs of Cape Miseno. The Sibyl, who doesn’t show her years, holds aloft a golden sprig rather than a bough, and Aeneas stands with his back to the viewer, as if he too is enjoying the view.

Turner’s last account is The Golden Bough, exhibited in 1834. It shows well how much his style had changed, although it retains compositional features from his earlier paintings. The Sibyl stands on the left, radiant in white light, and holding aloft a more substantial golden branch, with the golden sickle used to cut that branch, in her right hand. Down towards Lake Avernus are the Fates, dancing around a white glow. A couple of female companions of the Sibyl rest under the tree, but Aeneas is nowhere to be seen, although he might be in the middle of the Fates, perhaps. In the right foreground is a snake, a symbol of the underworld.

The most famous French person, born a Corsican of Italian origin, who died on the British South Atlantic island of Saint Helena, was the Emperor Napoleon I. His life, battles, wives and descendants have been painted repeatedly by some of the great artists of the nineteenth century, from Girodet to JMW Turner. This weekend I show a few of those images of greatness and downfall.

Napoleon Bonaparte rose rapidly through the French army following the French Revolution of 1789, until he became its commander for the campaign against Austria and Italy in 1796.

About a century later, Georges Clairin’s painting of Napoleon’s Troops in Front of San Marco, Venice provides a biased gloss on the fall of the Venetian Republic to Napoleon Bonaparte in 1797. The French occupation around 4 June may itself have been relatively peaceful, but by the end of July had been declared a siege, with the arrest and imprisonment of many Venetians. Later in the year, the French plundered the city of many of its artworks, something that Clairin seems to have overlooked.

As a national hero, Napoleon and his army travelled on to invade Egypt and Syria in 1798.

In 1806, Napoleon commissioned Pierre-Narcisse Guérin to paint for the Gallery of Diana in the Tuileries Palace. The result was Napoleon Bonaparte Pardoning the Rebels at Cairo, 23rd October 1798, completed in 1808.

Napoleon had taken the French army into Egypt in 1798, and conquered Alexandria and Cairo. On 21 October, the citizens of Cairo organised an uprising, and murdered the French commander and Napoleon’s aide-de-camp. The French fought back with artillery, then the cavalry fought their way back into the city, forcing the rebels out into the desert, or into the Great Mosque. Napoleon brought his artillery to bear on the mosque, following which his troops stormed the building, killing or wounding over five thousand. With control restored over Cairo, the leaders of the revolt were hunted down and executed. Following this, the city was taxed heavily in punishment, and put under military rule.

Guérin’s painting shows a very different event, in which Napoleon is engaged in open discourse with the rebels. However, the presence of French cavalry behind the Egyptians, and the action taking place at the far right, suggests the truth behind this ‘pardon’.

In 1810, Girodet painted the only reasonably accurate account of The Revolt of Cairo of 21 October 1798 and Napoleon’s massacre of the city’s residents. Most were killed when French cannons fired at the Al-Azhar Mosque where they were seeking refuge. This is a late oil sketch for the finished painting.

Léon Cogniet was also called to document Napoleon’s empire, painting his Bonaparte’s 1798 Egyptian Expedition (1835) on a ceiling in the Louvre Palace, as an explanation of how so many Egyptian artefacts came to be in Paris, ironically now on display in that same building.

Jean-Léon Gérôme made several paintings showing Napoleon in Egypt, including this highly detailed and intricate version of General Bonaparte and his Staff in Egypt from 1867.

In November 1799, Napoleon used these military victories to engineer a coup and became First Consul of the French Republic.

In early 1800, Napoleon made moves to reinforce French troops in Italy, so they could repossess territory lost to the Austrians in recent years. Leading his Reserve Army, he crossed the Alps via the Great St Bernard Pass in May, and his troops fought their first battle at Montebello on 9 June. Paul Delaroche was commissioned to paint a faithful account of this. His Napoleon Crossing the Alps from 1850 does at least sit the First Consul astride a mule, the only mount capable of carrying him in these conditions, but it’s still a good way from the truth. Napoleon’s face is bare, his left hand uncovered and resting on the pommel of his saddle, and he’s wearing a thin cloak and thin riding breeches.

In 1803, Napoleon sold the French territory of Louisiana to the United States, and at the end of the following year crowned himself Emperor of the French, giving him near-absolute power.

Among the paintings of François Flameng showing the Napoleonic period, one of the most striking is this scene of Napoleon Hunting in the Forest of Fontainebleau, in which the pack is closing in on a cornered stag as the sun sets.

At about this time, Pierre-Paul Prud’hon’s paintings became appreciated by the emperor’s court, and Napoleon himself. He was thus commissioned to paint the Empress Joséphine. Marie Josèphe Rose Tascher de La Pagerie, as she was before marrying the Emperor in late 1804, must have been forty-one or forty-two years old at the time of Prud’hon’s commission, and a widow with two children. Most unconventionally, it must have been agreed that she wouldn’t be portrayed in her official role of Empress.

Prud’hon’s black chalk Study for a Portrait of Empress Joséphine, from 1805, perhaps shows the original concept of the Empress in her role as patron of the arts, complete with a lyre, reclining on the coast, against a background of trees.

His finished painting of The Empress Joséphine (c 1805) dispenses with the lyre and seats her on a stone bench in woodland, looking pensive if not slightly wistful.

But Joséphine failed to become pregnant by Napoleon, and four years later he informed her that he had to find a wife who could provide him with an heir.
