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.
Vito Frazzi
Frazzi composed symphonic, choral and chamber music, and a number of operas. "Re Lear" was written between 1922 and 1928, but not performed until 1939; it is loosely based on Shakespeare's "King Lear". "Don Chisciotte", to Frazzi's own libretto derived from the "Don Quijote" of Cervantes and the "Vida de Don Quijote y Sancho" of Miguel de Unamuno, was composed between 1940 and 1950 and received its première at the Teatro Comunale of Florence on 28 April 1952. It consists of six scenes which may be performed either separately or together; a supplement to it, "Le nozze di Camaccio" ("the marriage of Camaccio"), though published, has apparently not been performed. Frazzi destroyed the score of his opera "L’ottava moglie di Barbablù" ("Bluebeard's eighth wife") after its première at the Teatro della Pergola in Florence in January 1940; the work is unpublished.
