Leporello is discovered keeping impatient watch for his master, who soon appears, pursued by Donna Anna, and vainly striving to break loose from her. Her cries for help bring the Commendatore, her father, who challenges the insolent intruder to fight, and falls by Don Giovanni's sword, to the consternation of the latter and of Leporello. Neither scorn nor mockery are expressed in the words, "Ah! gia cade il sciagurato," and the music is as far from such sentiments as the words. Da Ponte has sagaciously shown traits of natural human sentiment in Don Giovanni, and Mozart has not let these escape him. But he has no time to waste in regrets; he takes to flight, and immediately after Donna Anna returns with her affianced lover, Don Ottavio; she swoons at sight of the corpse, and as soon as she returns to herself makes Don Ottavio swear vengeance on the murderer. Don Giovanni, deaf to Leporello's reproaches, is confiding to him that he is in pursuit of a new adventure,[135] when a lady enters. This is Donna Elvira, whom he has deceived and deserted in Burgos, and who has followed him to claim his promise of marriage; he approaches her, and is consternated on seeing who she is. She overwhelms him with reproaches, and he refers her to Leporello for explanations and excuses, taking the opportunity of slipping away himself; Leporello, for her consolation, displays a list of his master's love intrigues, which he carries about with him. Enraged at this fresh insult, she resolves to sacrifice her love for her unfaithful lover to her thirst for vengeance. Masetto and Zerlina, with their village friends, are celebrating their wedding in the neighbourhood of Don Giovanni's casino, whither he has repaired by preconcerted arrangement. Zerlina's fresh loveliness attracts him; and, making acquaintance with the bridal party, he invites them all into his casino, but soon drives out Masetto, whose jealousy he has excited; and is on the point of winning Zerlina by his flattery and declarations of love when Elvira steps between them, warns Zerlina, and (spite of Don Giovanni's whispered protestation that she is a poor maniac in love with him and mad with jealousy) carries off the peasant maiden.[136] To Don Giovanni, thus left alone, enter Donna Anna and Ottavio, who greet him as a friend of the family, and claim his {DA PONTE'S LIBRETTO.} (163)
