When reading a book about the rise of a particular style of painting, you don’t expect lessons in political history, but while reading The Judgement of Paris, I learned much about nineteenth century France and its political dramas, of which I had formely known extremely little.  The to-ings and fro-ings of artistic style and taste in nineteenth century France were, France being France, a very political matter.  You can’t properly understand the paintings without understanding the politicians who, for their various political reasons, were trying to encourage or to discourage them, and who either inspired artists or failed to inspire them.

Hence passages in this book like this one (pp.62-65), which describes the rise to supreme power in France of Napoleon III.

Charles-Louis-Napoleon Bonaparte had been born in Paris on April 20, 1808, in a mansion in the Rue Cerutti (now the Rue Laffitte). His was a dizzying genealogy. His mother was Hortense de Beauharnais, the daughter of the Empress Josephine and the stepdaughter of Napoleon. His father, at least on paper, was Louis Bonaparte, Napoleon’s brother and the King of Holland from 1806 until his abdication in 1810. However, the marriage between Louis and Hortense was so unhappy ("Never was there so gloomy a ceremony,” wrote Louis of his own wedding) that the child’s true paternity was the object of much speculation. Candidates ranged from an admiral in charge of the Dutch navy, to various equerries and chamberlains, and even to Napoleon himself, who was rumoured to have nourished a soft spot for his stepdaughter.

The child, known as Louis-Napoleon, was so feeble at birth that he was bathed in wine and then wrapped in cotton wool. For several years thereafter, disappointed at having given birth to a boy, Hortense dressed him as a girl, an inauspicious start in life for someone whose horoscope proclaimed that he would wear the imperial crown of France. Still, greatness was impressed upon the child from an early age. An imperial decree gave him, at the age of two, the title of “Prince Louis-Napoleon,” and he received regular visits from his uncle the Emperor. One of his most vivid early memories, indeed, was of Napoleon picking him up by his head.

After Waterloo, the young prince, then aged seven, was exiled with his mother to a castle in Switzerland, where they were put under the surveillance of the British, French, Austrian, Russian and Prussian ambassadors. This exile was to last for many years, during which time the sickly child became a vigorous young man who fought by the side of Italian revolutionaries in Rome and conducted multiple love affairs in Switzerland. In London, working in the British Museum, he penned a political treatise, Ideas of Napoleonism, which he published in 1839. These musings were no idle occupation, for in 1832 the possibility of the young prince fulfilling the prediction of his horoscope and seizing the French throne had unexpectedly presented itself. Napoleon’s only legitimate son, the Duc de Reichstadt - the so-called Napoleon II - died of tuberculosis in Vienna, leaving Louis-Napoleon as the dynastic heir. He duly set about making plans to oust King Louis-Philippe, but an unsuccessful coup attempt in 1836 ended with his arrest, imprisonment and then another exile as he was sent to America aboard a French warship. In New York City he proved a great social success, meeting Washington Irving and impressing the locals with his wax-tipped moustache, a sight virtually unknown in America.

Four years later, in August 1840, Louis-Napoleon made a second attempt to reclaim what he regarded as his birthright. By this time he was living in London, in a mansion in Carlton Gardens staffed by seventeen fervent Bonapartists. In a daring bit of bluff, he and his band of fifty-six conspirators - his domestic servants among them - donned military uniforms, chartered a Thames pleasure boat named the Edinburgh Castle, and made for the French coast. On board were nine horses, two carriages, several crates of wine, and a tame vulture bought at Gravesend to improvise as an eagle, the totem of the Bonaparte family. This ragtag expeditionary force landed at Boulogne-sur-Mer but beat a hasty retreat when the presence on French soil of the Bonaparte heir failed to incite a popular uprising against the King. When the landing craft capsized in the Channel, the invasion ended with Louis-Napoleon clinging to a buoy and awaiting his rescue, which came in the form of the French National Guard. Fished from the waves, he was arrested and then sentenced to life imprisonment in the fortress at Ham, a medieval chateau in northern France. There he spent the next six years. His confinement does not seem to have been onerous, since he found opportunities to author a treatise on sugar beets, hatch a scheme to dig a canal across Nicaragua, and carry on a liaison with a ginger-haired laundress named Alexandrine Vergeot, who ironed the uniforms of the prison’s officers and lived in the gatekeeper’s house. He gave her lessons in grammar and spelling; she returned the favour with two children, both of whom: confusingly, were named Alexandre-Louis.

Louis-Napoleon escaped from Ham in 1846 by donning the uniform of a workman and casually strolling through the front gate with a plank of wood balanced on his shoulder. He then returned to England, where he served briefly as a special constable at the Marlborough Street police station and dallied with his latest mistress, Lizzie Howard, the daughter of a Brighton bootmaker. Soon, however, Louis-Napoleon’s destiny drew nigh. His chance came in 1848, the “Year of Revolution,” when an economic downturn and widespread crop failures, combined with demands for more liberal governments, triggered riots and revolutions across much of Europe. In February, following pitched battles in the streets of Paris, King Louis-Philippe abdicated his throne, fleeing to England as his Bonapartist rival crossed the Channel in the opposite direction. In December of that year, with a majority of four million votes, Louis-Napoleon was elected President of the Second Republic, and the former prisoner of Ham found himself enjoying the splendours of the Élysée Palace. Three years later, anticipating the end of his four-year term as President, he consolidated and increased his powers in a bloody coup d’état. In an operation code-named “Rubicon,” he dissolved the Constituent Assembly, imprisoned many of his opponents (including Adolphe Thiers), and sent the army into the streets of Paris, where 400 people were killed in violent skirmishes. One year later, on December 2, 1852, he proclaimed himself Emperor Napoleon III.

The Second Empire was one of the gaudiest and most vainglorious eras in the history of France. The years since Louis-Napoleon came to power had witnessed unprecedented economic expansion and commercial prosperity. Industry flourished, foreign trade tripled, household incomes increased by more than fifty per cent, and credit grew with the establishment of new financial institutions. Grand projects were undertaken, such as the building of the new sewers and boulevards in Paris and the laying of thousands of miles of railway and telegraph lines. Louis-Napoleon was making the country live up to his vision of “Napoleonism,” which, he had written, “is not an idea of war, but a social, industrial, commercial and humanitarian idea.” Louis-Napoleon may have disliked wars, but he had nonetheless involved France in the Crimean War, which ended in 1856, and in the war against Austria in Lombardy in 1859. The year 1859 also witnessed French military expeditions to Syria and Cochin-China, in the latter of which the Emperor’s troops occupied the capital, Saigon. In the following year, French troops invaded Peking and burned the Summer Palace.

His swashbuckling career notwithstanding, Napoleon III was a less than prepossessing character. He looked, to Théophile Gautier, like “a ringmaster who has been sacked for getting drunk,” while one of his generals claimed he had the appearance of a “melancholy parrot.” The urbane aristocrat Charles Greville, meeting him in London, found him “vulgar-looking, without the slightest resemblance to his imperial uncle.” In fact, the only thing that he seemed to have shared with Napoleon was a short stature: he was only 5 feet 5 inches tall. A reserved and thoughtful man with a waxed moustache, a pointed beard and hooded eyes, he possessed an air of inscrutability. It was said that he knew five languages and could be silent in all of them. Prince Richard von Metternich, the Austrian ambassador, called him the “Sphinx of the Tuileries.” But most of his opponents were guilty of underestimating his abilities, and by the 1860s he had become, as an English newspaper admitted, “the foremost man of all this world.”
