Which opera has more acts, Le prophète or La scala di seta?
La scala di seta La scala di seta (The Silken Ladder or Die seidene Leiter) is an operatic "farsa comica" in one act by Gioachino Rossini to a libretto by Giuseppe Maria Foppa. It was first performed in Venice, Italy, at the Teatro San Moisè on 9 May 1812. The overture has been frequently recorded and continues to be featured in the modern concert repertoire.
La mort d'Abel La mort d'Abel ("The Death of Abel") is an opera by the French composer Rodolphe Kreutzer. The libretto, by François-Benoît Hoffman, deals with the Biblical story of Cain and Abel. It was first performed in a three-act version at the Salle Montansier by the Académie Impériale de Musique (the Paris Opéra) on 23 March 1810 under the title "Abel". A revival at the Salle Le Peletier in 1823, in which the second act was cut, impressed the young Hector Berlioz.
