[2] At an early age he attracted attention for the perceived sensationalism in his art, although for a time his powerful brush dwelled with particular delight on scenes of bloodshed, such as the Murder in the Seraglio (1868) and the Death of Ravana, King of Lanka at the Toulouse Museum.

The Musée d'Orsay has his Cain fleeing before Jehovah's Curse; and for the Mairie of the fourth arrondissement of Paris he executed in grisaille a series of panels: Birth, Death, Marriage, War, etc.

Among his students with whom he was unsuccessful on this point were, for instance: Henri de Toulouse-Lautrec, Louis Anquetin, Eugène Boch, Paul Tampier, Émile Bernard and Vincent van Gogh.

Other students included Alphonse Osbert, Marius Borgeaud, Theodor Pallady, Chaïm Soutine and the Australian painter John Russell.

Despite his moment of glory as a Beaux-Arts professor he was almost forgotten by 1924 when he was run over by a taxi outside his studio, and is barely remembered today save as the teacher of pupils more illustrious than himself.
