Rossini's one-act farsa, L'inganno felice (The Happy Deception), with a libretto by Giuseppe Foppa, was first performed at the Teatro San Mois? in Venice on 8th January 1812. Isabella, the wronged and banished wife of Duke Bertrando, long supposed dead, has in fact been rescued from the sea by the villager Tarabotto. The Duke, with his wicked confidant Ormondo and the latter's henchman Batone, comes to the village, where the duplicity of the villains is revealed. The opera, among Rossini's earlier works, is set in a mining village. Foppa also provided the libretto for Rossini's La scala di seta (The Silken Ladder) and Il Signor Bruschino, and, with less success, for Sigismondo.
After an introductory passage, the overture launches into a livelier melody and material that includes characteristic dramatic elements. The second theme of the Allegro is taken from the Sinfonia in D of 1808, and the overture was used again for Ciro in Babilonia, staged in Ferrara in March of the same year.
