# Antigono (Mysliveček)

Antigono is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček composed to a libretto by the Italian poet Metastasio first produced in 1744 with music of Johann Adolf Hasse. This opera (and all the rest of Mysliveček's operas) belong to the serious type in Italian language referred to as opera seria. For a performance in the 1780s, it would only be expected that a libretto by Metastasio would be abbreviated and altered to suit contemporary operatic taste. The cuts and changes in the text made for the performance of Mysliveček's version are not attributable.

## Performance history

Antigono was the composer's last opera, first performed at the Teatro delle Dame in Rome on 5 April 1780 at a time when he was deathly ill with syphilis—he had only a few months more to live. He did have the pleasure to enjoy one last successful operatic production before he became completely incapacitated; the production did redeem the failures associated with the operas Armida and Il Medonte that were performed during the early part of the year.
No score survives for Mysliveček's last opera, but some of the arias are known from their inclusion in collections copied throughout Europe. The most successful of these was the rondò "Ho perduto il mio tesoro," which was disseminated in music prints and manuscripts well into the 19th century. It was particularly popular in England—and was even published in Philadelphia in the late 1790s. All of the performers in the production were male, since women were prohibited from appearing on stage in Roman theaters until Pius VII was elevated to the Holy See in the year 1800. Some also appeared in Il Medonte a few months earlier. The most distinguished cast members were the tenor Giovanni Ansani, a close professional associate of the composer, and the castrato Pietro Benedetti, the original interpreter of the rondò "Ho perduto il mio tesoro."

## Plot

The Egyptian princess Berenice is betrothed to the Macedonian King Antigono, but is actually in love with his banished son Demetrio. Antigono's daughter Ismene loves Alessandro, king of Epirus, who is the enemy of Macedonia. The opera portrays a violent struggle between Antigono and Alessandro. Typical for opera plots in the genre of opera seria, identities and the emotional relations between the characters become confused, and there is intense competition for love partners. Everything is resolved through the forgiveness of King Antigono at the end, with Berenice allowed to marry Demetrio.
