Artaserse is an opera in three acts by the Czech composer Josef Mysliveček, set to a popular libretto (or dramma per musica) by Metastasio that was originally performed in 1730. It was customary to alter the Metastasian text considerably for operas in the 1770s, but this one mainly adheres to the original Metastasian text, albeit with the placement of some scenes re-arranged and some scenes omitted. All of Mysliveček's operas are of the serious type in Italian referred to as opera seria. Performance history The opera was first performed at the Teatro San Carlo in Naples on 13 August 1774, the birthday of queen Maria Carolina of Naples. Mysliveček received the commission on the strength of his opera Romolo ed Ersilia, which was performed on the queen's birthday the year before. Artaserse was also successful and helped the composer secure commissions for the operas Demofoonte and Ezio at the court of Naples the next year. Roles Synopsis Eighteenth-century Italian operas in serious style are almost always set in a distant or legendary past and are built around historical, pseudo-historical, or mythological characters. The main character of Metastasio's Artaserse is based on the life of king Artaxerxes I of Persia, a ruler of the fifth century B.C., son of Xerxes I.

As the young lovers express their love for each other and their despair at Arbace's banishment, Artabano arrives carrying a bloody sword. His fury at Serse's treatment of his son and his desire for Arbace to become King have led him to assassinate Serse. Artabano confesses the murder to Arbace and exchanges his bloody sword for that of Arbace. Artaserse, the King's younger son, arrives with his guards. Artabano tells him of his father's death and accuses Artaserse's older brother Dario of the murder, "Who but he at dead of night could penetrate the palace? Who approach the royal bed? Nay, more, his royal ambition..." Artaserse commands Artabano to avenge his father's death by killing Dario. Later in the garden, Artaxerxes expresses his love to Semira, the daughter of Artabano and sister of Arbace. In the King's palace, the execution of
