Le roman d'Elvire is an opéra comique in three acts composed by Ambroise Thomas to a libretto by Alexandre Dumas (père) and Adolphe de Leuven. Also performed under the title Fantaisie de marquise, it was premiered on 4 February 1860 by the Théâtre Impérial de l'Opéra-Comique at the second Salle Favart theatre. Set in 17th-century Palermo, the opera blends elements of realism and fairy tale in its story of a young libertine who discovers that the wealthy old woman he thought he had married is actually the young and beautiful one whom he had jilted.[1]
