Neither Napoleon nor his wife Joséphine were faithful during their marriage, but she failed to produce the heir that the Emperor wanted. In 1809, he informed her that he had to find a wife who could provide an heir, and they divorced the following January. Pierre-Paul Prud’hon went on to paint her successor Marie-Louise of Austria as well.

Following his marriage to the eighteen year-old Marie-Louise of Austria, the new Empress became pregnant, and on 20 March 1811 gave birth to their son, who was soon made King of Rome. That year, Prud’hon painted this Portrait of the King of Rome, setting him asleep in a glade with a waterfall behind. Prud’hon was also involved in decorating a crib for the infant.

Meanwhile, the Emperor’s youngest sister Caroline had married one of Napoleon’s most brilliant cavalry officers who succeeded Joseph Bonaparte (the emperor’s older brother) as King of Naples. Élisabeth Louise Vigée Le Brun, known best for her brilliant pastel paintings, used oils for this portrait of Caroline Murat, Queen of Naples, with her Daughter Letizia in 1807.

Napoleon had continued leading French forces from his success at the Battle of Austerlitz in Austria in 1805, through Eastern Europe, then in Spain in 1808, where he installed his older brother Joseph as king. However, the French invasion of Russia in the summer of 1812 proved a disaster.

Ary Scheffer’s account of The Retreat of Napoleon’s Army from Russia in 1812 (1826) shows this march of death starting from Moscow in the middle of October 1812, which took until the middle of December to clear Russian territory. In the appalling winter weather, Napoleon’s Grande Armée is claimed to have shrunk from 100,000 to around 22,000.

The tide had turned. The following year Napoleon was decisively defeated at Leipzig, France was invaded, he was forced to abdicate in April 1814, and was exiled to the island of Elba, in the Mediterranean between Corsica and Tuscany. He escaped and returned to France, where he and his forces were defeated at the Battle of Waterloo in 1815. He was finally sent to the island of Saint Helena in the South Atlantic, where he died in 1821.

JMW Turner’s War. The Exile and the Rock Limpet from 1842 shows an imagined moment from Napoleon’s exile on the British island of Saint Helena, no doubt inspired by the return of the emperor’s ashes for state burial in France in 1840. In the background is one of the British sentries stationed on this remote island to guard the former emperor. Napoleon is bowing slightly to a tiny limpet on a rock, a symbol of the futility of war. The sunset behind forms the sea of blood resulting from Napoleon’s many battles across Europe.

Michel Ney (1769-1815) was a leading military commander during the French Revolutionary and Napoleonic Wars, and was made a Marshal of France by Napoleon. Following Napoleon’s defeat and exile in the summer of 1815, Ney was arrested, and tried for treason by the Chamber of Peers. He was found guilty, and executed by firing squad near the Luxembourg Gardens in Paris on 7 December 1815. He refused a blindfold, and was allowed to give the command to fire upon himself.

Jean-Léon Gérôme’s Death of Marshal Ney (1868) uses a similar narrative approach to Gérôme’s earlier paintings of the murder of Caesar, in showing a moment after the climax of the story. Ney’s body is abandoned, slumped and lifeless on the muddy ground, his top hat apart at the right edge of the canvas. Behind where he stood but a few moments ago there are half a dozen bullet impact marks on the wall, as the firing squad is being marched off, to the left and into the distance.

For a few brief weeks after Napoleon’s abdication, he tried to make his son the King of Rome his successor, as Napoleon II.

His cousin Louis Napoleon Bonaparte had been born in the Tuileries Palace in Paris. After Napoleon I had been sent to Saint Helena, the rest of the emperor’s family were dispersed elsewhere. Louis Napoleon joined the Swiss Army, developed political aspirations, and in 1836 led an attempted coup from Strasbourg. After a period of exile in London, he attempted a second coup in 1840 that quickly turned into a fiasco. He escaped from prison in 1846, fled to London, only to return to Paris after the French Revolution of 1848. He then gained a place in the National Assembly, where he campaigned successfully for election as President of France. He staged a further coup in December 1851, and won a referendum enabling him to proclaim himself Napoleon III, Emperor of the French, on 2 December 1852.

Gérôme articulated Napoleon III’s aspirations for empire in his elaborate and formal painting of the Reception of Siamese Ambassadors by Napoleon III (1864), depicting a grand reception held at Fontainebleau on 27 June 1861. Gérôme had attended in the role of semi-official court painter (commissioned by the State), made sketches of some of the key figures, and was further aided by photographs made by Nadar. He also included himself, and the older artist Ernest Meissonier (1815-1891), in the painting: I believe that they are both at the back, at the far left.

Cabanel’s life-sized full-length portrait of the Emperor Napoleon III from about 1865 proved controversial, as many felt that his image of their emperor should have greater grandeur. Some critics even accused Cabanel of making him look like a hotel manager or waiter, and I can see their point. The Empress Eugénie and Napoleon’s family had no such qualms, though: Cabanel’s painting was hung in the Tuileries Palace, and when the Second Empire collapsed, and the empress fled to Britain, she took this painting with her into exile.

Napoleon III clearly lacked his uncle’s flair for military leadership, and declaration of war against Prussia on 19 July 1870 led to a series of disastrous defeats ending with the Battle of Sedan, a fortified French city in the Ardennes. The French Army surrendered to the Prussians and Napoleon III became a prisoner of war.

Emil Hünten’s undated Welcome of Empress Eugénie by Prussian Soldiers shows an event that never occurred. When the Empress was told of her husband’s surrender to the Prussians at the Battle of Sedan, she is reported to have said: “No! An Emperor does not capitulate! He is dead!… They are trying to hide it from me. Why didn’t he kill himself! Doesn’t he know he has dishonored himself?!” With hostile crowds forming outside her Tuileries Palace, she slipped out to find sanctuary in the company of her American dentist, then fled to England by yacht on 7 September 1870. She was later joined by the former emperor, and the couple lived at Chislehurst in Kent.

Perhaps the most lasting memorial to these French emperors is the Suez Canal. During Napoleon’s Egyptian campaign in 1798, he had engineers and others search for an ancient canal running north from the Red Sea. In 1804, the new Emperor considered constructing a canal to connect the south-eastern Mediterranean with the Red Sea. Early in the reign of Napoleon III, Ferdinand de Lesseps obtained a concession to construct the canal that Napoleon I had dreamed of. The Suez Canal was officially opened on 17 November 1869, with both the Empress Eugénie of France and the Crown Prince of Prussia present as guests.

Painted by the great marine artist Ivan Aivazovsky shortly after that official opening in 1869, Suez Canal shows a convoy of ships passing through in an unearthly light. Within a year the Second Empire had fallen, but Napoleon’s canal went on.

In this second article looking at how difficult it is to depict the purpose or intent of an inanimate object, specifically here a poisonous liquid, I show some more classical history paintings before ending with modern retellings of Arthurian legend.

The jury of the Prix de Rome chose another grim subject for 1805, the suicide of the great Athenian statesman Demosthenes, who had incited the Athenians to seek independence from the Macedonian Empire. He escaped to a sanctuary on the island of Kalaureia (modern Poros), where he was discovered by the Macedonians. To avoid capture, he drank poison from a reed pen.

Felix Boisselier shows Demosthenes looking up at a statue of Poseidon, clinging onto the altar as he weakens. His pen has fallen to the ground, and his left arm is outstretched towards Archias as he approaches to arrest him.

When the jury again chose the suicide of Demosthenes as the subject in 1879, Alfred-Henri Bramtot’s successful painting shows Demosthenes’ limp body being supported from falling in front of the altar, with Archias angry and frustrated at the far right. The altar tripod is at the left edge, and the orator’s pen and writing materials are behind it.

Without knowing this story in detail, you’d spend a long time guessing that it was the original poison pen.

Last in this succession of suicides set as subjects for the Prix de Rome is that for 1887, the suicide of Themistocles. Henri-Camille Danger recreates the moment of great drama as Themistocles, visibly aged, raises a goblet ready to drink to his death. Although the goblet is of obvious significance, there’s little to suggest that it’s about to end the life of Themistocles.

Just a couple of years before his death in 1889, Alexandre Cabanel found a tragic heroine in Cleopatra Testing Poisons on Condemned Prisoners (1887). Known for her ruthless pursuit of power and her alleged beauty, Cleopatra spent much of her life as co-ruler of Egypt with one of her brothers, including Ptolemy XIV. A few months after the assassination of Julius Caesar in Rome, in 44 BCE, Cleopatra had returned to Egypt, where she had her brother killed by poison, making her co-ruler her son by Caesar, Caesarion. It’s likely that this painting refers to an apocryphal story that Cleopatra had candidate poisons tested out on prisoners to help her select the one to be used to kill her younger brother. The clues are here, if you know what you’re looking for.

In Arthurian legend, King Mark and Sir Tristram fell out over their love for another knight’s wife. The king then devised a way to destroy Tristram, by sending him to Ireland to bring La Beale Isode back for Mark to marry. The Queen of Ireland sent Tristram back with her daughter and her lady-in-waiting. As they were sailing back to Cornwall, Tristram and Isode drank together from a golden flask containing a potion that ensured their love for one another would never end, setting up the love triangle.

Isolda with the Love Potion (1870) is one of Frederick Sandys’ late Pre-Raphaelite or Aesthetic paintings, and shows as femme fatale Isolde of the legend and Wagner’s opera Tristan and Isolde. The opera had only received its première five years earlier, although its next production didn’t occur until 1874. In the operatic version, the couple drink what they believe is a poisonous potion, which instead of killing them both, makes them fall in relentless love with one another. Sandys shows only Isolde, the cup of poison in her right hand, looking into the distance. The floral language, red roses in particular, is symbolic of love.

Herbert James Draper’s Tristan and Isolde from 1901 shows the couple on the deck of the ship as they return to Cornwall. The golden goblet is empty as he looks in desperation into her half-closed eyes. Behind them the crew are rowing through the choppy waters.

John Duncan’s ornate tempera painting of Tristan and Isolde from 1912 shows them holding a crystal glass in their hands, staring into one another’s eyes just before they drink, although by now it’s impossible to tell whether they think the potion will kill them, or make them fall in love.

Koloman Moser’s Tristan and Isolde from about 1915 shows Isolde persuading Tristan to drink the potion, as his sword rests at their feet.

In his painting of the couple from 1916, John William Waterhouse gives a faithful pictorial account of them drinking the potion from a golden chalice, while on the ship carrying them back to King Mark. Is it poison, though? Without knowing the literary reference, I doubt whether we’d ever guess.
