Which opera has more acts, Der Rosenkavalier or Manon?
Der Rosenkavalier Der Rosenkavalier (The Knight of the Rose or The Rose-Bearer), Op. 59, is a comic opera in three acts by Richard Strauss to an original German libretto by Hugo von Hofmannsthal. It is loosely adapted from the novel "Les amours du chevalier de Faublas" by Louvet de Couvrai and Molière’s comedy "Monsieur de Pourceaugnac". It was first performed at the Königliches Opernhaus in Dresden on 26 January 1911 under the direction of Max Reinhardt, Ernst von Schuch conducting. Until the premiere the working title was "Ochs von Lerchenau". (The choice of the name Ochs is not accidental, for in German Ochs means ox, which depicts the character of the Baron throughout the opera.)
Nitétis Nitétis is an opera by the French composer Charles-Louis Mion, first performed at the Académie Royale de Musique (the Paris Opera) on 11 April 1741. It takes the form of a "tragédie en musique" in a prologue and five acts. The libretto, by Jean-Louis-Ignace de La Serre, Sieur d'Anglade, is based on the mythological history of Ancient Egypt. The work was a failure at its premiere.
