Pietro Antonio Domenico Trapassi, better known by his pseudonym of Pietro Metastasio (3 January 1698 – 12 April 1782), was an Italian poet and librettist, considered the most important writer of opera seria libretti.
Pietro Metastasio was an Italian poet and librettist, considered the most important writer of opera seria libretti. At the age of thirty-two, he was appointed court composer to Emperor Charles VI of Vienna. There he met his lifelong friend and companion Nicolo Martines.
Metastasio resided with the Martines family for the entire rest of his life (from about 1734 to 1782). His presence would prove crucial to Nicolo’s daughter, Marianne's career. Marianna Martines was an Austrian singer, pianist and composer of the classical period.
The Martines family lived in rooms in a large building on the Michaelerplatz, "a stately building still standing in the Kohlmarkt."
In 1755 the Countess Althann died, and Metastasio was reduced to the society which gathered round him in the bourgeois house of the Martinez. He sank rapidly into the habits of old age; and, though he lived till the year 1782, he was very inactive. He bequeathed his whole fortune of some 130,000 florins to the six children of his friend Nicolo Martines or von Martinez. He had survived all his Italian relatives.
