Ciro riconosciutoCiro riconosciuto is an opera libretto in three acts by Pietro Metastasio, dating to around 1736.SettingsIt has only been set less than thirty times and was performed for the first time on 28 August 1736 at festivities in Vienna for the birthday of Elisabeth Christine, wife of Charles VI, Holy Roman Emperor. At that performance it was set to music by Antonio Caldara. A second setting, by Niccolò Jommelli for Venice, in 1749, was highly esteemed by Metastasio himself, as was the version by Johann Adolph Hasse for Dresden, 1751, in which Hasse's wife Faustina Bordoni played Mandane. Gioacchino Cocchi composed a setting for a London premiere in 1759 - it was considered the composer's best Italian opera. A German translation of the libretto appeared in 1772 under the title of Der erkannte Cyrus in the fourth volume of Johann Anton Koch's unfinished complete edition of Metastasio's works.
