Do the operas Don Carlos and Pomone have the same number of acts?
Pomone (opera) Pomone ("Pomona") is a pastoral opera in a prologue and five acts by Robert Cambert with a libretto by Pierre Perrin. It has been described as "effectively the first French opera." It was first performed in Paris at the Jeu de Paume de la Bouteille theatre belonging to Cambert and Perrin's Académie d'Opéra on 3 March 1671. The production had ballets choreographed by Des Brosses and sets and machinery designed by Alexandre de Rieux, marquis de Sourdéac. The novelty of the work drew large audiences and the opera enjoyed 146 performances over the eight months of its run. The score of "Pomone" has only partially survived.
L'écume des jours (opera) L'écume des jours (English: "The Foam of Days") is an opera in three acts (14 scenes) by the Russian composer Edison Denisov. The French (also German and Russian) text is by the composer based on the novel of the same title by Boris Vian. It was composed in 1981.
