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.
I due Figaro (Mercadante)
The manuscript of "I due Figaro" was discovered in 2009 in Madrid by an Italian musicologist. Two years later, on 24 June 2011, the first production of the opera in modern times was presented at the Ravenna Festival, conducted by Riccardo Muti. The music of this opera, enriched by several dances of Spanish sonority but hampered by a libretto at times weak, was judged "lightweight and brilliant, gracefully written, often refined in the effects of the counterpoint, in the intertwining of the internal voices, in the quality of instrumentation and rhythmic inventiveness". The opera is introduced by the "Sinfonia caratteristica spagnola", a lively ouverture based on typical Spanish dances, that obtained a good success and was also printed as a separate piece.
