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'Olimpiade (Pergolesi) L'Olimpiade is an opera in the form of a dramma per musica in three acts by the Italian composer Giovanni Battista Pergolesi. Pergolesi took the text, with a few modifications, from the libretto of the same name by Pietro Metastasio. The opera first appeared during the Carnival season of 1735 at the in Rome and "came to be probably the most admired" of the more than 50 musical settings of Metastasio’s drama.
