The Marriage of Figaro (play)
The play formed the basis for an opera with a libretto by Lorenzo Da Ponte and music by Mozart, also called "The Marriage of Figaro" (1786). In 1799, another opera based on the same play, "La pazza giornata, ovvero Il matrimonio di Figaro", was produced in Venice with libretto by Gaetano Rossi and music by Marcos Portugal.
Ortensio Mauro
(Bartolomeo) Ortensio Mauro (1632/33 – 1725) was an Italian writer and librettist.
He was born in 1632 or 1633 in Padua, where he studied literature at the university. He entered the service of the family of the Elector of Hanover in Germany as Italian secretary and eventually became attached to the court of Sophia, Electress of Hanover. Mauro wrote poetry, occasionally served the royal family as a diplomat and wrote the libretti for eight operas by fellow Italian, composer Agostino Steffani including "Henrico Leone", an opera written to inaugurate the new court theatre in Hanover in 1689.
His opera "La superbia d'Alessandro" was the basis for the libretto of George Frederic Handel's opera "Alessandro".
