His elder brother, Emmanuel Antoine Joseph Ansiaux (1761-1800), worked in politics and law, a pathway the younger Ansiaux was to have taken before turning to art.[1][2][3]
His works, taken from sacred and profane history, and poetical subjects, are numerous, and place him among the best artists of the French school in the 19th century. He also painted portraits of several distinguished persons, ministers, and generals of Napoleon I.
He was known for working in the Romantic-inspired Troubadour style of French historical painting. The Grove Dictionary of Art criticized his works done in this style, calling them "very uneven" and "often laborious."[4]
