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 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.
