Nabucco, Giuseppe Verdi

ACT I. In the Temple of Solomon in Jerusalem, the Israelites bewail their fate: Nabucco (Nebuchadnezzar), king of Assyria, has attacked them with his hordes and is desecrating the city. As they offer prayers, Zaccaria (Zacharius), their high priest, enters with his sister, Anna, and Nabucco's daughter, Fenena, whom the Jews hold hostage. He counsels his people to be steadfast, as peace is within their reach, and reassures them that the Lord will not forsake them. Ismaele, nephew of the king of Jerusalem and leader of the military, comes in with soldiers to say Nabucco is sweeping all before him. Zaccaria hopes for a miracle and turns Fenena over to Ismaele for safekeeping. When the others leave, following a hymn, we learn that Ismaele and Fenena are in love, having met in Babylon when he served there as ambassador. Even then they had a difficult time, because her jealous sister, Abigaille, loved Ismaele too. As they talk, Abigaille bursts in wearing warrior garb and leading a band of Assyrians (disguised as Hebrew soldiers) to occupy the temple. She greets Ismaele with scorn, then privately tells him he can save his people and earn a new kingdom if he returns her love. Saying he cannot, he offers to forfeit his life for his people, while Fenena prays to the God of Israel to shield Ismaele. The Hebrew crowd reappears, frightened because Nabucco is approaching. As the conqueror enters the temple, Zaccaria confronts him, denouncing his blasphemous arrogance and threatening to stab Fenena. But Ismaele holds back Zaccaria's blow and delivers Fenena to her father. As Zaccaria and the other Jews revile Ismaele, Nabucco orders the temple looted and burned.

ACT II. In Nabucco's palace in Babylon, Abigaille has found a parchment that could cause her ruin, since it certifies that she is not Nabucco's daughter but the child of slaves. She swears vengeance on Nabucco and his appointed heiress, Fenena, but wistfully reflects that the love she felt for Ismaele could have changed her life. The High Priest of Baal comes to say that Fenena has freed the Hebrew prisoners. As a result of her treason, the religious authorities have decided to offer Abigaille the throne instead, telling the people that their king has fallen in battle. She rejoices that the daughter of slaves will now have everyone at her feet. Elsewhere in the palace, Zaccaria prays for the ability to persuade the Assyrians to put aside their false idols. He will begin by converting Fenena, whose apartment he enters. Two Levites, sent for by Zaccaria, appear and are surpised to meet the outcast Ismaele. As they upbraid him, Zaccaria, accompanied by Fenena and Anna, pardons Ismaele, for he saved a fellow Hebrew-the newly converted Fenena. The aged palace adviser Abdallo rushes in to tell Fenena about the reports of the king's death and to warn that her life is in danger. Before she can escape, the High Priest of Baal, followed by Abigaille and the Assyrian populace, proclaims Abigaille ruler and pronounces a death sentence on the Hebrews. When Abigaille demands the royal scepter, Fenena refuses to yield it. At that moment, to the astonishment of all, Nabucco enters, takes the crown and places it on his own head. Everyone quakes in dread before the irate monarch, who announces he is not only king but god, having overthrown both Baal and Jehovah. As he tries to force Zaccaria and Fenena to prostrate themselves, lightning strikes him and knocks the crown from his head; it also renders him insane. Abigaille retrieves the crown.

ACT III. In the Hanging Gardens of Babylon, the High Priest of Baal and the populace hail Abigaille as ruler. The High Priest presses her to put the Israelites to death, but before she can sign the warrant, the disheveled Nabucco wanders in, hoping to sit once more on his throne. Abigaille dismisses the others and explains to Nabucco that she is serving as regent, since he is not well enough to rule; she gives him the warrant, hoping to trick him into ordering his own daughter's death. When she taunts him for lack of resolution, he signs. Then Nabucco remembers: what of Fenena? She too will die, retorts Abigaille. When Nabucco tries to find in his garments the document proving that Abigaille is an impostor, she confronts him with it and tears it to bits. Nabucco calls the guards but learns they are no longer his servants: their job is to keep him locked up. Reduced to pleading with Abigaille for Fenena's life, he meets with stony adamancy. By the banks of the Euphrates, the Hebrews are resting from forced labor. Their thoughts ascend "on golden wings" to their lost homeland. Zaccaria predicts they will overcome captivity and obliterate Babylon with the Lord's help.

ACT IV. In his royal apartment, Nabucco awakens from a troubled sleep to hear voices outside calling Fenena's name. He goes to the window and sees her being led to execution. Trying the door, he remembers he is a prisoner. Desperate, he kneels to pray to the God of the Hebrews for forgiveness, pledging to convert himself and his people. His reason returns, and when Abdallo and soldiers come to see why he is trying to force the door, he convinces them that he is his old self again. Crying for a sword, he rallies his followers to regain the throne. In the Hanging Gardens, executioners stand ready to do away with Zaccaria and his flock. The old man hails Fenena as a martyr, and she asks the Lord to receive her into heaven, but Nabucco arrives and orders the statue of Baal destroyed. As if by supernatural powers, it falls of its own accord. Abigaille takes poison and confesses her crimes, urging that Ismaele and Fenena be reunited; dying, she prays to the God of Israel to pardon her. Nabucco tells the Israelites to return to their native land and rebuild their temple, declaring that he himself now serves Jehovah. The crowd acknowledges a miracle and renders praises to God.
