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.
La journée aux aventures La journée aux aventures ("The Day of Adventures") is an opera by the French composer Étienne Méhul. It takes the form of an "opéra comique" in three acts. It was first performed at the Opéra-Comique, Paris on 16 November 1816. The libretto is by Pierre-David-Augustin Chapelle and Louis Mezières-Miot. This was the last of the composer's works to be premiered in his lifetime and was a great success; it enjoyed 66 performances before the end of 1817 and helped remedy the financial problems of the Opéra-Comique. It was revived to acclaim in a German translation in Berlin in December 1839.
