followed by
another cavatina of almost equal beauty and tenderness ("Ah! bello a
me ritorna"). In the next scene Adalgisa, retiring from the sacred
rites, sings of her love for Pollione, and as she closes is met by the
proconsul, who once more urges her to fly to Rome with him. The duet
between them is one of great power and beauty, and contains a
strikingly passionate number for the tenor ("Va, crudele"). Oppressed
by her conscience, she reveals her fatal promise to Norma, and
implores absolution from her vows. Norma yields to her entreaties, but
when she inquires the name and country of her lover, and Adalgisa
points to Pollione as he enters Norma's sanctuary, all the priestess's
love turns to wrath. In this scene the duet, "Perdoni e ti compiango,"
is one of exceeding loveliness and peculiarly melodious tenderness.
The act closes with a terzetto of great power ("O! di qual sei tu"),
in which both the priestess and Adalgisa furiously denounce the
faithless Pollione. In the midst of their imprecations the sound of
the sacred shield is heard calling Norma to the rites.

The second act opens in Norma's dwelling, and discovers her children
asleep on a couch. Norma enters with the purpose of killing them, but
the maternal instinct overcomes her vengeful thought that they are
Pollione's children. Adalgisa appears, and Norma announces her
intention to place her children in the Virgin's hands, and send her
and them to Pollione while she expiates her offence on the funeral
pyre. Adalgisa pleads with her not to abandon Pollione, who will
return to her repentant; and the most effective number in the opera
ensues,--the grand duet containing two of Bellini's most beautiful
inspirations, the "Deh! con te li prendi," and the familiar "Mira, O
Norma," whose strains have gone round the world and awakened universal
delight. Pollione, maddened by his passion for Adalgisa, impiously
attempts to tear her from the altar in the temple of Irminsul,
whereupon Norma enters the temple and strikes the sacred shield,
summoning the Druids. They meet, and she declares the meaning of the
signal is war, slaughter, and destruction. She chants a magnificent
hymn ("Guerra, guerra"), which is full of the very fury of battle.
Pollione, who has been intercepted in the temple, is brought before
her. Love is still stronger than resentment with her. In a very
dramatic scena ("In mia mano alfin tu sei") she informs him he is in
her power, but she will let him
