Lucia di Lammermoor is an opera (original name: "dramma lirico") in two parts and three acts by Gaetano Donizetti. The premiere took place on September 26, 1835 at the Teatro San Carlo in Naples. A French version revised by Donizetti premiered at the Théâtre de la Renaissance in Paris on August 6, 1839. The libretto was written by Salvadore Cammarano, based on the novel The Bride of Lammermoor by Walter Scott. The opera is about two lovers from the two warring noble families Ashton and Ravenswood, who are only united in death. Donizetti's work is considered to be one of the high points of the Belcanto era and the ideal type of romantic opera with Lucia's mad scene (Il dolce suono) as the high point.
