Il Bajazet

Bajazet (Italian pronunciation: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.
Bajazet is a pasticcio. It was a common practice during Vivaldi's time for composers to borrow and adapt arias from other composers with their own works for an opera. Vivaldi himself composed the arias for the good characters (Bajazet, Asteria and Idaspe) and mostly used existing arias from other composers for the villains (Tamerlano, Irene, Andronico) in this opera. Some of the arias are reused from previous Vivaldi operas. The table below lists the origin of some of the arias used in Bajazet.
