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.
The Last Savage The Last Savage is an opera in three acts by composer Gian Carlo Menotti. Menotti wrote his own libretto, originally in the Italian language ("L'ultimo selvaggio"). The opera was translated into French ("Le dernier sauvage") by Jean-Pierre Marty for the work's first (private) performance at the Opéra-Comique in Paris on 21 October 1963, followed the next day by the public premiere. George Mead translated the work into English for the opera's American premiere at the Metropolitan Opera the following year.
