Editing Norma (opera) (section)

==== ''Scene 1: The grove of the druids'' ====

Oroveso leads the druids in a procession in the forest to pray for victory against the invading Romans: (Oroveso and druids: "Ite sul colle, o druidi" / "Go into the hills, Druids"). The druids pray that Norma will come and have the courage to broker peace with the Romans: (Druids and Oroveso: "Dell'aura tua profetica" / "With thy prophetic aura, imbue her, O terrible God".) All leave to go to the temple.

Pollione and Flavio enter. Although Norma has secretly broken her vows in order to love him and has borne him two children, Pollione tells Flavio that he no longer loves Norma, having fallen in love with the priestess Adalgisa. But he expresses some remorse, describing his dream in which Adalgisa was beside him at the altar of Venus and a huge storm arose: (Pollione, aria: "Meco all'altar di Venere" / "With me at the altar in Rome was Adalgisa dressed in white, veiled all in white.") The storm presaged disaster for both Norma and himself: "Thus does Norma punish her faithless lover," he declares. They hear the trumpets sounding to announce Norma's arrival. Flavio urges his friend to leave, but Pollione stands firm, proclaiming that he will confront Norma and the druids with a superior power and overthrow their altars: (Cabaletta: "Me protegge, me difende" / "I am protected and defended")

As Norma leads the druids and priestesses, the crowd proclaims: "Norma viene" / "Norma is coming" and, as Oroveso awaits her, they describe her dress and manner. All kneel as she approaches. "The time is not ripe for our revenge", she declares, stating that Rome will perish one day by being worn down. Then, with the mistletoe in hand, she approaches the altar with a plea to the moon (the "Chaste Goddess"): ([[cavatina]]: "Casta diva" / "Chaste goddess"). She pleads that the goddess shed upon earth the peace that she has created in heaven. She calls for all to complete the rites and then clear the uninitiated from the grove. To herself, she declares that she cannot hurt Pollione, but desires that things return to where they used to be: (Cabaletta: "Ah! bello a me ritorna" / "Return to me, O beautiful one"). The assembled crowd accepts her cautious approach, and all leave the grove.

''Later that night: The Temple of [[Irminsul]] in the grove''

Adalgisa prays at the temple, remembering with some sorrow how she became involved with Pollione. He enters, telling her that she prays to a cruel god and is not trying to invoke the god of love. As she appears to reject him, he declares (Aria: "Va crudele" /"Go, O cruel one") but he is convinced that he cannot leave her. He is distraught, and she doesn't show she is equally torn, until the moment he declares that he must return to Rome the following day. He begs Adalgisa to go with him: (Duet: Pollione, then Adalgisa, then together: "Vieni in Roma" / "Come to Rome"). She resists him, but finally agrees that they will leave together the following day.
