Droit du seigneur
In Mozart's "The Marriage of Figaro", which premiered in 1786 with a libretto by Lorenzo Da Ponte, the comic plot revolves around the successful efforts of the young bride and groom, Figaro and Susanna, to block the efforts of the unfaithful Count Almaviva to seduce Susanna. To achieve his aim, the frustrated Count threatens to reinstitute "droit du seigneur". It was based on a play by Pierre Beaumarchais.
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.
