Do the operas Don Carlos and Pomone have the same number of acts?
Don Carlos Don Carlos is a five-act grand opera composed by Giuseppe Verdi to a French-language libretto by Joseph Méry and Camille du Locle, based on the dramatic play "Don Carlos, Infant von Spanien" ("Don Carlos, Infante of Spain") by Friedrich Schiller. The opera is usually performed in an Italian translation. In addition, it has been noted by David Kimball that the Fontainebleau scene and auto da fé "were the most substantial of several incidents borrowed from a contemporary play on Philip II by Eugène Cormon".
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.
