All his famous pictures are of date between 1850 and 1864, his earlier work being of comparatively little value. His mother, who survived him, instituted the Troyon prize for animal pictures at the École des Beaux Arts. Troyon's work is fairly well known to the public through a number of large engravings from his pictures. In the Wallace Gallery in London are "Watering Cattle" and "Cattle in Stormy Weather"; in the Glasgow Corporation Gallery is a "Landscape with Cattle"; the Louvre contains his famous "Oxen at Work" and "Returning to the Farm"; while the Metropolitan Museum of Art and other galleries in America contain fine examples of his pictures. His "Vallée de la Toucque, Normandy", is one of his greatest pictures; and at Christie's sale-room in 1902 the single figure of a cow in a landscape of but moderate quality fetched £7350. Émile van Marcke (1827–1891) was his best-known pupil.
