Act I
Scene i: A room in Don Magnifico’s tumbledown house
As her two spoilt step-sisters, Clorinda and Tisbe, are locked in one of their habitual quarrels, Cenerentola (Angelina) is busy with the household chores. She sings of a king who was wise enough to discern the goodness and innocence of his bride to be. Alidoro, Don Ramiro's tutor, arrives disguised as a beggar. The two sisters mock him and try to drive him out of the house, while Cenerentola offers him food and drink. Courtiers announce the imminent arrival of the Prince, Don Ramiro, who is to escort Magnifico's daughters to a ball at the palace, during which the Prince will choose a bride.
The tumult arouses Magnifico, who proceeds to relate a strange dream, which he believes presages royal connections for his daughters and himself. Prince Ramiro enters disguised as his valet Dandini, for Alidoro has indicated to him that the woman worthy of being his bride is one of the Magnifico household. Cenerentola's shock at the unexpected presence of a young stranger in the house causes her to drop the dishes she had been holding. The Prince's eyes meet Cenerentola's, and they immediately fall in love.
The "Prince" (Dandini in disguise) arrives, and the two sisters leave for the ball. Prince Ramiro and Dandini overhear Cenerentola pleading in vain with her father to allow her to attend the ball as well. Magnifico ruthlessly insults her while fawning on the Prince and his valet. Alidoro arrives and announces that he has information of a third daughter in the household, but Magnifico says that she is in fact dead.
Alidoro, disguised once again as a beggar, arrives to escort Cenerentola to the ball. He consoles her, saying that the Good Lord will not allow innocence to be downtrodden.
Scene ii: A room in Don Ramiro’s palace
"Prince" Dandini offers Magnifico the position of court vintner after the latter has sampled thirty barrels of wine with no apparent difficulty. Dandini and the Prince are mystified by Alidoro's idea that one of the sisters would be a worthy bride for the Prince. Clorinda and Tisbe spot the “Prince”, and he offers them his “valet” as a husband. They are outraged, but their attention is soon diverted to a girl strangely resembling Cenerentola, who arrives accompanied by Alidoro. Dandini calls the company in to dinner. As the curtain descends confusion reigns supreme.
