Barbara. However, Annina identifies this "wife" for the Duke as the masked Ciboletta. The Duke goes along with Ciboletta's pretence, as he recalls the serenade he had sung to Barbara at previous carnival times. Delacqua pushes the supposed Barbara forward to put his own case for the position of the Duke's steward, but Ciboletta instead asks for a place for Pappacoda as the Duke's personal cook, and the Duke is only too ready to oblige her. Delacqua departs to join Barbara in Murano, leaving the Duke to take supper with Annina and Ciboletta.

As the Duke courts the two ladies, Caramello and Pappacoda repeatedly interrupt. The cook gives a timely discourse on his culinary arts before the senators' wives arrive seeking the Duke's attention.

Fanfares announce the start of the grand Carnival procession, in which all sections of Venetian life are represented and, when it is over, the pigeons of St. Mark's flutter down into the square. Delacqua has returned, distressed by the discovery that Barbara is not in Murano and, when she appears with Enrico, the young man reassures Delacqua with a story of how he has rescued his aunt Barbara from an impostor gondolier. The Duke is decidedly less interested in Barbara when he discovers that she
