Bajazet (Italian pronunciation: [bad͡ʒaˈzeːt]; also called Il Tamerlano ) is an Italian opera composed by Antonio Vivaldi in 1735. Its libretto was written by Agostino Piovene. It was premiered in Verona, during the Carnival season of that year. This opera (catalog number RV 703) is presented in 3 acts, with a three-movement sinfonia as an introduction. The story is about the fate of Bajazet (known as Beyazid I) after being captured by Tamerlane (Timur Lenk). The famous aria, "Sposa son disprezzata" is from this opera.
