Il Ruggiero

Il Ruggiero (full name: Il Ruggiero ovvero L'eroica gratitudine) is an opera in three acts composed by Johann Adolph Hasse to a libretto by Pietro Metastasio. It was first staged on 16 October 1771 for the wedding of Archduke Ferdinand Karl with Maria Beatrice d'Este in the Teatro Regio Ducale, Milan. It was both Metastasio's last libretto and Hasse's last opera, as well as the thirty-second Metastasio libretto Hasse had set to music.
