Which opera, if any, between La scala di seta and The Barber of Seville is performed in fewer acts ?
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.
Achille et Polyxène Achille et Polyxène ("Achilles and Polyxena") is a tragédie lyrique containing a prologue and five acts based on Virgil's "Aeneid" with a French libretto by Jean Galbert de Campistron. The opera's overture and first act were composed by Jean-Baptiste Lully, who died from a conducting injury before he could complete the score. The prologue and the remaining acts are the work of his pupil Pascal Collasse who finished the work, eight months after Lully's death on March 22, 1687. The opera was first performed on November 7, 1687, by the Paris Opera at the Théâtre du Palais-Royal in Paris.
