Are both Savitri and Le devin du village considered operas?
Le devin du village The Village Soothsayer (French: "Le devin du village") is a one-act French opera (intermède) by Jean-Jacques Rousseau, who also wrote the libretto. It was the first work in the repertory of the Académie Royale de Musique for which the text and music were by the same author.
La naissance de la lyre La naissance de la lyre ("The Birth of the Lyre") is an opera (styled a "conte lyrique") in one act by the French composer Albert Roussel. The libretto, by Théodore Reinach, is based on the satyr play "Ichneutae" by Sophocles. It was first performed at the Paris Opéra on 1 July 1925 with choreography by Bronislava Nijinska.
