Pierre Beaumarchais
In 1786, Wolfgang Amadeus Mozart composed an opera, "Le Nozze di Figaro", based on "The Marriage of Figaro", with a libretto by Lorenzo Da Ponte based on the play. Several composers including Paisiello in 1782 wrote operas based on "The Barber of Seville". Rossini's 1816 version is his most successful work and still often performed. In 1966, Darius Milhaud composed an opera, "La mère coupable", based on "The Guilty Mother".
The Marriage of Figaro
"The Marriage of Figaro" continues the plot of "The Barber of Seville" several years later, and recounts a single "day of madness" () in the palace of Count Almaviva near Seville, Spain. Rosina is now the Countess; Dr. Bartolo is seeking revenge against Figaro for thwarting his plans to marry Rosina himself; and Count Almaviva has degenerated from the romantic youth of "Barber" into a scheming, bullying, skirt-chasing baritone. Having gratefully given Figaro a job as head of his servant-staff, he is now persistently trying to exercise his "droit du seigneur" – his right to bed a servant girl on her wedding night – with Figaro's bride-to-be, Susanna, who is the Countess's maid. He keeps finding excuses to delay the civil part of the wedding of his two servants, which is arranged for this very day. Figaro, Susanna, and the Countess conspire to embarrass the Count and expose his scheming. He retaliates by trying to compel Figaro legally to marry a woman old enough to be his mother, but it turns out at the last minute that she really is his mother. Through Figaro's and Susanna's clever manipulations, the Count's love for his Countess is finally restored.
