Maometto II
During the Turkish siege of Negroponte, Venetian commander Erisso and the noble Calbo urge the city to resist. Erisso’s daughter Anna reveals that she fell in love with a man called Uberto, who turns out to be Maometto, the sultan leading the siege. Maometto releases Erisso and Calbo after Anna threatens suicide, then takes her to his tent and urges her to become his queen. Anna refuses, gives him back his seal of authority and asks her father to marry her to Calbo. After the Venetians defeat Maometto, he returns seeking the seal. Anna says she has married Calbo and stabs herself at her mother’s tomb.
