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.
Marino Faliero (opera)
Marino Faliero (or "Marin Faliero") is a "tragedia lirica", or tragic opera, in three acts by Gaetano Donizetti. Giovanni Emanuele Bidéra wrote the Italian libretto, with revisions by Agostino Ruffini, after Casimir Delavigne's play. It is inspired by Lord Byron's drama "Marino Faliero" (1820) and based on the life of Marino Faliero ("c."1285-1355), the Venetian Doge.
