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.
Figaro chain
The name of the chain was widely used by Italian chainmakers inspired by the operas "The Barber of Seville" (by Gioachino Rossini) and "The Marriage of Figaro" (by Wolfgang Amadeus Mozart). These operas were based on the plays "The Barber of Seville" and "The Marriage of Figaro" by Pierre Beaumarchais.
