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.
Semirâma Semirâma is an opera in three acts by Ottorino Respighi to a libretto by Alessandro Cerè based on Voltaire's 1748 play "Sémiramis", the same subject used for Rossini's Semiramide. "Semirâma" premiered on 20 November 1910 at the Teatro Comunale in Bologna. The première obtained a great success, with several calls for the composer and the singers.
