Charles-Caius Renoux (born in Paris,1795; died in Paris, 14 March, 1846) was a French painter, lithographer, and illustrator. He first achieved success with paintings of medieval churches, particularly the ruins of cloisters and monasteries destroyed during the French Revolution, works for which he is still best known. Renoux also painted landscapes, large-scale battle scenes, and historical subjects, works which uniquely prepared him for the final phase of his career, the creation of spectacular dioramas, the “moving pictures” of the era. He also taught at the École des Beaux-Arts in Paris; his notable students included Narcisse Berchère and Hector Hanoteau.
