It was premiered by the Prague Italian opera at the National Theater (of Bohemia), now called the Estates Theatre, on 29 October 1787. Da Ponte's libretto was billed as a "dramma giocoso", a common designation of its time that denotes a mixing of serious and comic action.

The genre developed in the Neapolitan opera tradition, mainly through the work of the playwright Carlo Goldoni in Venice.

Composers Baldassare Galuppi, Niccolò Piccinni, and Joseph Haydn set Goldoni's texts to music.  - Lorenzo Da Ponte (10 March 174917 August 1838) was an Italian, later American opera librettist, poet and Roman Catholic priest.
