Petrosellini was born in Corneto,
Papal State (now
Tarquinia,
Lazio) and spent most of life in Rome at the Papal Court where he held the title of "
Abate". He was also a member of several
accademie (learned societies), most notably the
Accademia degli Arcadi for whom he wrote under the pseudonym "Enisildo Prosindio". Amongst his most well-known libretti is Paisiello's
Il barbiere di Siviglia.
La finta giardiniera, set by
Pasquale Anfossi in 1774 and
Wolfgang Amadeus Mozart in 1775, has been ascribed to him, but it is questionable whether it is in his style. He also wrote several libretti for
Domenico Cimarosa and
Pasquale Anfossi. One of his last works was the libretto for Cimarosa's
I nemici generosi which premiered at the
Teatro Valle in 1795. Petrosellini died in Rome in 1799. ==References==
