Cosi Fan Tutte.

Officers Ferrando and Guglielmo are certain that their lovers Dorabella and Fiordiligi are faithful to them, but the cynical Don Alfonso challenges them to a bet that the women will be unfaithful given the chance. The officers thus pretend to go off to war, and return in disguise as Albanian strangers, to woo Dorabella and Fiordiligi incognito. The ladies are initially frosty, but soon warm to their new suitors, spurred on by their maid Despina. Performed at the La Scala Theatre in Milan.
