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.
The Abduction of Figaro
The Abduction of Figaro is a comic opera, described as "A Simply Grand Opera by P. D. Q. Bach," which is actually the work of composer Peter Schickele. It is a parody of opera in general, and the title is a play on two operas by Wolfgang Amadeus Mozart: "The Abduction from the Seraglio" and "The Marriage of Figaro". Those two operas, "Così fan tutte", and "Don Giovanni", as well as Gilbert and Sullivan's "The Pirates of Penzance" are among the core inspirations for the piece.
