Which opera has more acts, Le prophète or La scala di seta?
Le prophète Le prophète ("The Prophet") is a grand opera in five acts by Giacomo Meyerbeer. The French-language libretto was by Eugène Scribe and Émile Deschamps, after passages from the "Essay on the Manners and Spirit of Nations" by Voltaire. The plot is based on the life of John of Leiden, Anabaptist leader and self-proclaimed "King of Münster" in the 16th century.
Artaserse (Hasse) Artaserse is an opera ("dramma per musica") in three acts composed by Johann Adolph Hasse to an Italian libretto adapted from that by Metastasio by Giovanni Boldini. It premiered at the Teatro di San Giovanni Grisostomo in Venice on 11 February 1730, shortly after the libretto's first setting by Leonardo Vinci premiered in Rome 6 days earlier. Metastasio's libretto, "Artaserse", has been used in more than 90 works. Hasse himself would later re-work the score for performances at the Opernhaus am Zwinger in Dresden (1740) and the Teatro di San Carlo in Naples (1760).
