NABUCCO

Act I

For I have set my face against this city for evil, and not for good, saith the Lord: it shall be given into the hand of the king of Babylon, and he shall burn it with fire. (Jeremiah 21:10)

Jerusalem. The Hebrews pray for aid in the temple of Solomon as Nabucco, King of Babylon, advances on the city. The High Priest Zaccaria arrives with Nabucco's daughter Fenena, who is being held captive by the Hebrews. He reassures his people that the Almighty will not abandon them. Ismaele and Fenena, who had fallen in love with each other during the period of the Babylonian captivity, remain alone together. He had escaped with help from the girl, who then followed him to Jerusalem. Their discussion is interrupted by the appearance of Abigaille, Fenena's half-sister. She too is in love with Ismaele, whose people she will deliver from Nabucco if only he will reciprocate her feelings, but the youth rejects her offer. The Hebrews retreat to the sanctuary as Nabucco leads his troops into the temple, where Zaccaria threatens to kill Fenena. Ismaele disarms the high priest and hands Fenena over to Nabucco, who orders that the holy edifice be destroyed.

Act II

Behold, the whirlwind of the Lord goeth forth with fury, a continuing whirlwind: it shall fall with pain upon the head of the wicked. (Jeremiah 30:23)

Babylon. In Nabucco's absence, Fenena is serving as regent. Abigaille learns that she is descended from slaves. Calculating that Fenena will soon be ruling over Babylon at Ismaele's side, she swears revenge against her sister and father. Fenena releases the Hebrew captives. The High Priest of Baal declares this to be treason and places Abigaille on the throne, spreading the rumour that Nabucco has died. Zaccaria prays for the Babylonians to give up idolatry. Fenena converts to Judaism. Abigaille and the High Priest of Baal seize her, and the new ruler is about to coronate herself when Nabucco enters. He takes the crown away from her and declares that he is not only a king, he is also God. After he is suddenly struck down by a vengeful bolt of lightning, the victorious Abigaille takes the crown for herself.

Act III

Therefore the wild beasts of the desert with the wild beasts of the islands shall dwell there, and the owls shall dwell therein: and it shall be no more inhabited for ever; neither shall it be dwelt in from generation to generation. (Jeremiah 50:39)

In the hanging gardens of Babylon, Abigaille is being exalted by her court. The High Priest of Baal is urging for the Hebrews to be executed, but before the Queen can order this, the still raving Nabucco appears. Abigaille tricks him into delivering the death sentence, which also applies to Fenena. To no avail, Nabucco pleads for his child's life. On the banks of the Euphrates, the Hebrew captives dream of returning home. Zaccaria prophesies their liberation and the downfall of Babylon.

Act IV

Declare ye among the nations, and publish, and set up a standard; publish, and conceal not: say, Babylon is taken, Baal is confounded, Merodach is broken in pieces; her idols are confounded, her images are broken in pieces. (Jeremiah 50:2)

From his prison cell, Nabucco watches as the Hebrews, together with Fenena, are led in for execution. In his despair, he prays to the God of Israel for forgiveness, vowing that he and his people will take up the Jewish faith. His mind suddenly unclouded, he assembles his troops and leads them to regain the throne and save his daughter's life. Fenena is praying for forgiveness in heaven when Nabucco rushes in and halts the execution. Repenting of her deed, Abigaille poisons herself and begs God for forgiveness. Nabucco converts to Judaism, grants the captives their freedom and sends them on their way home to rebuild the temple. Jews and Babylonians together praise the Lord.
