Mozart and Da Ponte use the theme of "fiancée swapping", which dates back to the 13th century; notable earlier versions are found in Boccaccio's Decameron and Shakespeare's play Cymbeline. Elements from Shakespeare's The Taming of the Shrew are also present. Furthermore, it incorporates elements of the myth of Procris as found in Ovid's Metamorphoses, vii.[10]  Place: Naples  Time: the 18th century

Così fan tutte

Singspiel in three acts by Wolfgang Amadeus Mozart. The German libretto is by Gottlieb Stephanie, based on Christoph Friedrich Bretzner's Belmont und Constanze, oder Die Entführung aus dem Serail. The plot concerns the attempt of the hero Belmonte, assisted by his servant Pedrillo, to rescue his beloved Konstanze from the seraglio of Pasha Selim. The work premiered on 16 July 1782 at the Vienna Burgtheater, with the composer conducting.

The Abduction from the Seraglio

Two years prior to the opening scene, the nobleman Florestan has exposed or attempted to expose certain crimes of the nobleman Pizarro. In revenge, Pizarro has secretly imprisoned Florestan in the prison over which Pizarro is governor. The jailer of the prison, Rocco, has a daughter, Marzelline, and a servant (or assistant), Jaquino. Florestan's wife, Leonore, came to Rocco's door dressed as a boy seeking employment, and Rocco hired her. On orders, Rocco has been giving Florestan diminishing rations until he is nearly starved to death. Place: A Spanish state prison, a few miles from Seville Time: Late 18th century
