Ballet in two acts with choreography and libretto by Saint-Léon, music by Pugni, sets by Despléchin and Thierry, and costumes by Lormier. Premiered 19 Jan. 1849 at the Paris Opera, with Cerrito and Saint-Léon. The ballet is a retelling of the Faustian legend, in which a young violinist Urbain allows the Satanic Doctor Matheus to bewitch his violin so that its beautiful sound will win the heart of his beloved, Hélène. When Matheus comes to claim the violinist's soul, he resists and the ballet ends happily with Urbain delivered from evil and the lovers united. At the ballet's premiere Saint-Léon played the violin as well as dancing the role of Urbain.
