Un ballo in maschera
ACT I
Scene i
The governor’s mansion
Riccardo, the governor of Boston, is giving an audience. Oscar, his page, brings him the list of guests invited to a masked ball. Riccardo is overjoyed to see included the name of Amelia, the wife of his secretary Renato, with whom - despite his conscience¬- he is in love. The faithful Renato tells him of a plot against his life but Riccardo brushes the warning aside. A judge arrives with papers to sign, banishing a fortune-teller named Ulrica for her evil influence. Oscar intercedes for her. Riccardo, for a lark, suggests that they all go in disguise to the dwellings of the sorceress and test her powers. The conspirators, Samuel and Tom, fall in with the scheme, seeing in it an opportunity to carry out their plot against Riccardo.
Scene ii
Ulrica's place
Riccardo enters disguised as a fisherman. Without his knowledge, Amelia also comes to consult the fortune-teller. Concealed, Riccardo hears Amelia ask for a magic potion, which will uproot her love to Riccardo from her heart. Ulrica tells her of such a herb which can only be gathered at midnight in the place where the gallows stand. When Amelia leaves, Riccardo asks to have his fortune told. Ulrica tells him he will die by the hand of the friend who will next shake his hand. Renato enters. Riccardo goes forward and grasps his hand. He tells Ulrica this is the hand of his most trusted friend.
