The story of 'La Sonnambula' is rather foolish, but it suited Bellini's idyllic style, and the work is perhaps the happiest example of his _naif_ charm. Amina, a rustic damsel, betrothed to Elvino, is a confirmed somnambulist, and her nocturnal peregrinations have given the village in which she dwells the reputation of being haunted by a spectre. One night, Amina, while walking in her sleep, enters the chamber in the inn where Rodolfo, the young lord of the village, happens to be located. There she is discovered by Lisa, the landlady, to the scandal of the neighbourhood and the shame of her lover Elvino, who casts her from him and at once makes over his affections to the landlady. Amina's sorrow and despair make her more restless than ever, and the following night she is seen walking out of a window of the mill in which she lives, and crossing the stream by a frail bridge which totters beneath her weight. Providence guards her steps, and she reaches solid earth in safety, where Elvino is waiting to receive her, fully convinced of her innocence. Bellini's music is quite the reverse of dramatic, but the melodies throughout 'La Sonnambula' are graceful and tender, and in the closing scene he rises to real pathos. In 'Norma' Bellini had the advantage of treating a libretto of great power and beauty, the work of the poet Romani, a tragedy which, both in sentiment and diction, contrasts very strongly with the ungrammatical balderdash which composers are so often called upon to set to music. Norma, the high priestess of the Druids, forgetting her faith and the traditions of her race, has secretly wedded Pollio, a Roman general, and borne him two children. In spite of the sacrifices which she has made for his sake, he proves faithless, and seduces Adalgisa, one of the virgins of the temple, who has consented to abandon her people and her country and to fly with him to Rome. Before leaving her home, Adalgisa, ignorant of the connection between Norma and Pollio, reveals her secret to the priestess, and begs for absolution from her vows. At the news of her husband's faithlessness Norma's fury breaks forth, and her indignation is equalled by that of Adalgisa, who is furious at finding herself the mere plaything of a profligate. Pollio, maddened by passion, endeavours to tear Adalgisa from the altar of the temple, but is checked by Norma, who strikes the sacred shield and calls the Druids to arms. Pollio, now a prisoner, is brought before her for judgment, and she gives him a last choice, to renounce Adalgisa or to die. He refuses to give up his love, whereupon Norma, in a passion of self-sacrifice, tears the sacred wreath from her own brow and declares herself the guilty one. Pollio is touched by her magnanimity, and together they ascend the funeral pyre, in its flames to be cleansed from earthly sin.
