Orontea is an opera in a prologue and three acts by the Italian composer Antonio Cesti with a libretto by Giacinto Andrea Cicognini (revised by Giovanni Filippo Apolloni).

It was revived more than 17 times before 1700,[1] including in Genoa, Rome, Florence, Turin, Milan, Bologna, Venice, Palermo, Naples, Hannover.

Modern performances started in 1961 at the Piccola Scala [it] in Milan with Teresa Berganza and Carlo Cava [de], Bruno Bartoletti conducting.

[4][5] A new staging has been included in the 2023/2024 season of the Teatro alla Scala in Milan, conducted by Giovanni Antonini, directed by Robert Carsen and Stéphanie d'Oustrac in the title role.

Giacinta, disguised as the boy "Ismero", arrives at Orontea's court and explains she was behind the ambush of Alidoro, having been sent to kill him by the Queen of Phoenicia.
