Vernet was born to Carle Vernet, another famous painter, who was himself a son of Claude Joseph Vernet. He was born in the Paris Louvre, while his parents were staying there during the French Revolution. Vernet quickly developed a disdain for the high-minded seriousness of academic French art influenced by Classicism, and decided to paint subjects taken mostly from contemporary culture. Therefore, he began depicting the French soldier in a more familiar, vernacular manner rather than in an idealized, Davidian fashion. Some of his paintings that represent French soldiers in a more direct, less idealizing style, include Dog of the Regiment, Trumpeter's Horse, and Death of Poniatowski.
