Griselda (Vivaldi)

The opera uses a revised version of the 1701 Italian libretto by Apostolo Zeno that was based on Giovanni Boccaccio's The Decameron (X, 10, "The Patient Griselda").

Pinchgut Opera (Sydney) staged four performances November–December 2011 in the City Recital Hall and in Rio de Janeiro Municipal Theatre in June 2012 in concert form with Francesconi, Franco, Nardotto, Bitar, Christensson and Faria conducted by Marco Pace.

Now, after the recent birth of a son has led to another rebellion from the Thessalians against Griselda as a queen, Gualtiero is forced to dismiss her and promises to take a new wife.

Costanza sings of her torn affections (betrothed to Gualtiero but in love with Roberto) in the coloratura aria Agitata da due venti.

Griselda returns to her home in the countryside where she is pursued by the villainous courtier Ottone, who is completely besotted with her and has surreptitiously fomented the popular uprisings in order to derail her marriage.
