Adelson e Salvini

Adelson e Salvini (Adelson and Salvini) is a three act opera semiseria composed by Vincenzo Bellini from a libretto by Andrea Leone Tottola. The opera was based on the 1772 novel Épreuves du Sentiment by François-Thomas-Marie de Baculard d'Arnaud, and it draws on a previously performed play by Prospère Delamare.
Bellini's first opera was written as his final project at the Naples San Sebastiano Conservatory, when the composer was 23 years old. It was the custom at the Conservatory to introduce promising students to the public with a dramatic work. Bellini styled his project an opera semiseria and it was first performed at the Teatro del Conservatorio di San Sebastiano in Naples on 12 February 1825. Various revisions were undertaking "with a view to professional staging", but it was never performed.
