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.
Ortensio Mauro
(Bartolomeo) Ortensio Mauro (1632/33 – 1725) was an Italian writer and librettist.
He was born in 1632 or 1633 in Padua, where he studied literature at the university. He entered the service of the family of the Elector of Hanover in Germany as Italian secretary and eventually became attached to the court of Sophia, Electress of Hanover. Mauro wrote poetry, occasionally served the royal family as a diplomat and wrote the libretti for eight operas by fellow Italian, composer Agostino Steffani including "Henrico Leone", an opera written to inaugurate the new court theatre in Hanover in 1689.
His opera "La superbia d'Alessandro" was the basis for the libretto of George Frederic Handel's opera "Alessandro".
