Siroe re di Persia [Siroe](‘Siroes, King of Persia’)
- Don Neville
Libretto by Pietro Metastasio, first set by Leonardo Vinci (1726, Venice).
Cosroe, King of Persia, has slain Asbite, King of Cambaya, in combat. Emira, Asbite’s daughter, seeks revenge, and enters the court of Cosroe in male attire under the assumed name of Idaspe; only Siroe, elder son of Cosroe and in love with Emira, knows her identity. Meanwhile, Medarse, younger son of Cosroe, has methodically ingratiated himself with his father in order to displace Siroe as heir. Affronted that Cosroe should consider choosing between his sons, Siroe incurs his father’s anger while Medarse gains the promise of the throne. When Siroe refuses to aid Emira’s cause, she spurns his love and spitefully suggests to Laodice, in love with Siroe and loved by Cosroe, that her affections are reciprocated. Outraged when Siroe corrects this fabrication, Laodice informs Cosroe that Siroe is his rival and has attempted to seduce her. This Siroe overhears while concealed in Cosroe’s chambers, where he has left an anonymous note warning the king that his life is in danger; he also overhears Medarse name him as traitor. Siroe reveals his presence, an act that only compounds the accusations against him....
