Between Pelléas et Mélisande and Riders to the Sea, which one has more acts?
Riders to the Sea (opera) Riders to the Sea is a short one-act opera by Ralph Vaughan Williams, based on the play of the same name by John Millington Synge. The composer completed the score in 1927, but it was not premiered until 1 December 1937, at the Royal College of Music, London. The opera remained largely the province of students and amateurs until it entered the repertoire of Sadler's Wells in 1953.
Vénus et Adonis Vénus et Adonis is an opera ("tragédie en musique") in a prologue and 5 acts composed by Henri Desmarets to a libretto by Jean-Baptiste Rousseau. Based on the story of Venus and Adonis in Book X of Ovid's "Metamorphoses", it was first performed by the Académie Royale de Musique at the Théâtre du Palais-Royal in Paris on 28 July 1697 with Marie Le Rochois and Louis Gaulard Dumesny in the title roles. Desmarets staged a major revival of the work with a new prologue at the court of Leopold, Duke of Lorraine in 1707. During the composer's lifetime, it was performed in Germany, Belgium, and France, but then fell into obscurity. Its first staging in modern times took place at the Opéra de Nancy on 28 April 2006.
