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".
Pimmalione Pimmalione ("Pygmalion") is an opera in one act by Luigi Cherubini, first performed at the Théâtre des Tuileries, Paris on 30 November 1809. The libretto is an adaptation by Stefano Vestris of Antonio Simone Sografi's Italian translation of the text Jean-Jacques Rousseau wrote for his "scène lyrique" "Pygmalion" (1770). It is based on the Classical legend of the sculptor Pygmalion.
