I puritani

(The Puritans) is an opera in three acts by Vincenzo Bellini, although it was originally written with two acts and changed to three acts on the advice of Gioachino Rossini with whom the young composer had become friendly. The music was set to a libretto by Count Carlo Pepoli, an Italian émigré poet who Bellini had met at a salon run by the exile Princess Belgiojoso, which became a meeting place for many Italian revolutionaries.
