The Lyon School is a term for a group of French artists which gathered around Paul Chenavard. It was founded by Pierre Revoil, one of the representatives of the Troubadour style. It included Victor Orsel, Louis Janmot and Hippolyte Flandrin, and was nicknamed "the prison of painting" by Charles Baudelaire. It was principally inspired by philosophical-moral and religious themes, and as a current was closely related to the British Pre-Raphaelite painters and poets.
