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.
Lucia di Lammermoor
Lucia di Lammermoor is a "dramma tragico" (tragic opera) in three acts by Gaetano Donizetti. Salvadore Cammarano wrote the Italian-language libretto loosely based upon Sir Walter Scott's historical novel "The Bride of Lammermoor".
