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".
Le roi s'amuse Le roi s'amuse (] ; literally, "The King Amuses Himself" or "The King Has Fun") is a French play in five acts written by Victor Hugo. First performed on 22 November 1832 but banned by the government after one evening, the play was used for Verdi's 1851 opera "Rigoletto".
