Aeneidos Liber Quartus [The Aeneid] recap

After hearing Aeneas recount Troy's fall and his wanderings, Dido falls helplessly in love with him. Anna encourages the match, while Juno engineers a storm during a hunt that leaves the pair together in a cave; Dido treats their union as a marriage. As the lovers neglect their public duties, the rejected Iarbas appeals to Jupiter. Mercury then orders Aeneas to remember his destiny in Italy. Aeneas prepares to leave, insisting that divine command gives him no choice. Dido's appeals, accusations, and attempt to use Anna as an intermediary cannot change his mind. After the Trojans sail, Dido curses Aeneas and calls for lasting enmity between their descendants. She climbs a pyre built around his abandoned possessions and kills herself with his sword, while the unsuspecting Anna reaches her too late.

Previously in the Aeneid: the Trojan prince Aeneas escaped the destruction of Troy carrying responsibility for his surviving people and for a destiny that will lead to a new homeland in Italy. Hostile Juno drove his fleet off course to North Africa, where Dido, the widowed founder and queen of Carthage, welcomed the Trojans. At a feast, Aeneas recounted Troy's fall and his subsequent travels. Venus arranged for Dido to be struck by love for her son, leaving the queen emotionally exposed as the fourth book begins.

Dido confesses to Anna that her love for Aeneas has shaken her vow to remain faithful to her dead husband, Sychaeus. Anna urges her to embrace the match. During a hunt, Juno sends a storm that drives Dido and Aeneas into the same cave; Dido thereafter regards their union as a marriage, and both leaders neglect the work of their peoples. Iarbas, a rejected suitor, appeals to Jupiter, who sends Mercury to remind Aeneas of his promised future in Italy. Aeneas orders secret preparations to sail. Dido discovers them and pleads with him, but he maintains that he must obey the gods. Neither her direct appeal nor Anna's mediation changes his decision. After ominous signs and a tormented night, Dido has Anna build a pyre under the pretense of destroying reminders of Aeneas. The Trojans depart before dawn. Dido curses Aeneas and invokes permanent hostility between their descendants, then kills herself on the pyre with his sword. Anna arrives in horror, and Iris, sent by Juno, finally releases Dido's spirit from her suffering.

Aeneas secretly readies his fleet, then resists Dido's pleas and leaves Carthage under cover of night. Dido curses him and his descendants, asking for enduring hatred between their peoples. She mounts the pyre that Anna believed was intended for a ritual to end her love, takes Aeneas's sword, and kills herself. Anna arrives too late and holds her dying sister. Because Dido's death comes before its appointed time, her spirit struggles to depart until Juno sends Iris to release it. The book closes with the Trojan ships at sea and the queen of Carthage dead, turning the failed union into both a personal catastrophe and a legendary origin for future conflict between Carthage and Rome.
