La straniera is an opera in two acts with music by Vincenzo Bellini to an Italian libretto by Felice Romani, based on the novel L'Étrangère by Charles-Victor Prévot, vicomte d'Arlincourt, although writer Herbert Weinstock also adds that it is "more likely [based on] a dramatization of [that novel] in Italian by Giovan Carlo, barone di Cosenza" since he then quotes a letter from Bellini to his friend Francesco Florimo in which he says that Romani "certainly will not follow the play" [suggesting then that they were aware of its existence.] Wikipedia
