Pasquariello is reluctantly keeping watch before the house of the Commandant, when Don Giovanni rushes out, and strives to free himself from Donna Anna, who snatches the mask from his face and calls her father to help; he appears and falls in combat, a terzet for the men closing the introduction [there is no overture]. After some little talk, Don Giovanni flies with Pasquariello. Donna Anna hastens in with her betrothed Duca Ottavio, and finds to her horror the corpse of her father [accompanied recitative]; more composedly she acquaints him with Don Giovanni's villany, and declares her intention of retiring to a nunnery until Ottavio shall have discovered and punished the murderer [air],[126] to which he consents sorrowfully [air]. Don Giovanni, waiting for Donna Eximena in a casino, converses with Pasquariello, when Donna Elvira enters in travelling guise; she has been deceived and deserted by Don Giovanni in Burgos, and has followed him hither [air]. They recognise each other, Don Giovanni refers her to Pasquariello for the motives of his departure, and goes out. Pasquariello gives her the list of his master's mistresses [air]; she vows to gain justice or be avenged. Don Giovanni enters in loving converse with Eximena, and satisfies her jealous doubts of his fidelity [air]. A peasant couple, Biagio and Maturina, are celebrating their wedding [chorus and tarantella]. Pasquariello pays court to the bride, but on the entrance of Don Giovanni retires; and Don Giovanni treats the bridegroom so rudely that he finally goes off in dudgeon [air]. Don Giovanni befools Maturina by flattery and a promise of marriage. Two scenes are wanting here (14 and 15). Biagio enters in jealous mood, but is appeased by Maturina [scena and rondo]. Eximena questions Pasquariello concerning his master, and rejoices to learn that he is constant to her [air]. Don Giovanni is besieged with questions by Donna Elvira, Eximena, and Maturina all at once, and satisfies each in turn by assuring her that love for him has turned the brains of the other two.[127] Duca Ottavio is discovered in the mausoleum adding the inscription to the statue which the Commandant had erected to himself in his lifetime. Don Giovanni enters with Pasquariello to view the monument, and obliges the latter to invite the statue [duet]. The cook Lanterna attends Don Giovanni; Elvira comes and meets him returning with Pasquariello; she exhorts him earnestly to repent, but he scornfully refuses, whereupon she leaves him
