Antoine-Jean Gros in 1792 for the grand prix. Around this time, however, on the recommendation of the École des Beaux Arts, he was employed on the execution of portraits of the members of the National Convention, but disturbed by the development of the Revolution, Gros left France in 1793 for Italy.
He supported himself at Genoa by the same means, producing a great quantity of miniatures and fixés. He visited Florence, but returned to Genoa where he made the acquaintance of Joséphine de Beauharnais. He followed her to Milan, where he was well received by her husband, Napoleon Bonaparte.
On 15 November 1796, Gros was present with the army near Arcola when Bonaparte planted the French tricolor on the bridge. Gros seized on this incident, and showed by his treatment of it (entitled Bonaparte at the pont d'Arcole) that he had found his vocation. Bonaparte at once gave him the post of inspecteur aux revues, which enabled him to follow the army, and in 1797 nominated him to the commission charged with selecting the spoils which should enrich the Louvre.
In 1799, having escaped from the besieged city of Genoa, Gros made his way to Paris, and in the beginning of 1801 took up his quarters in the Capucins. His esquisse of the Battle of Nazareth (now in the Musée de Nantes) gained the prize offered in 1802 by the consuls, but was not carried out, owing it is said to the jealousy of Jean-Andoche Junot felt by Napoleon; but he indemnified Gros by commissioning him to paint his own visit to the pest-house of Jaffa. Les Pestiférés de Jaffa (Louvre) was followed by The Battle of Aboukir, 1806 (Versailles), and The Battle of Eylau, 1808 (Louvre). According to the Encyclopædia Britannica Eleventh Edition, "these three subjects – the popular leader facing the pestilence unmoved, challenging the splendid instant of victory, heart-sick with the bitter cost of a hard-won field – gave Gros his chief title to fame."
Britannica further remarks that as long as the military element remained bound up with French national life, Gros received from it a fresh and energetic inspiration which carried him to the very heart of the events which he depicted; but as the army and its general separated from the people, Gros, called on to illustrate episodes representative only of the fulfilment of personal ambition, ceased to find the nourishment necessary to his genius, and the defect of his artistic position became evident. Trained in the sect of the Classicists, he was shackled by their rules, even when by his naturalistic treatment of types, and appeal to picturesque effect in color and tone, he seemed to run counter to them.
At the Salon of 1804, Gros debuted his painting Bonaparte Visiting the Plague Victims of Jaffa. The painting launched his career as a successful painter. It depicts Bonaparte in Jaffa visiting soldiers infected with the bubonic plague. He is portrayed reaching out to one of the sick, unfazed by the illness.
While Bonaparte did actually visit the pesthouse, later, as his army prepared to withdraw from Syria, he ordered the poisoning (with laudanum) of about fifty of his plague-infected men. The painting was commissioned as damage control when word spread of his actions. The painting is in the neoclassical style, though it shows elements such as the lighting and a taste for the exotic that are precursors to the upcoming Romantic ideals.
