Le Villi is an opera-ballet in two acts that marked Giacomo Puccini's debut in the world of opera. It was first staged at Teatro dal Verme in Milan in 1884. Librettist Ferdinando Fontana based the story on the ancient legend of the Willis, fantastic creatures representing the souls of young women who were the victims of love.
Anna and Roberto are engaged, but during a trip the man is seduced by a woman and his fianc?e dies of heartbreak. Roberto, who is by then abandoned and left penniless, is haunted by remorse and attacked by the revengeful fairies and Anna's ghost.
All the elements of the more mature Puccini are already recognizable: the characters of Anna and Roberto anticipate the "love victim" and the "man without qualities" archetypes of his later operas, whereas some of the composer's touches of harmony and aria structure foresee his future success.
