In Book VI of Vergil's Aeneid, which deals with Aeneas' journey to the underworld, how does Dido respond to Aeneas?

In Book 6 of Vergil's Aeneid, when Aeneas sees Dido in the underworld, she remains silent, turns away from him, and returns to the spirit of her first husband, Sychaeus, who was murdered in Sidon.

Dido ignoring Aeneas in the underworld is meant to recall Ajax's ignoring of Odysseus in their underworld encounter in Book 11 of Homer's Odyssey. Both Dido and Ajax ended up killing themselves because of their anger at Aeneas and Odysseus, respectively.

It is also interesting that both Dido and Ajax kill themselves with swords. Typically, the women of mythology hang themselves. In Sophocles' Ajax, Greek Ajax kills himself with a sword he received as a gift from the Trojan Hector. In Aeneid 4, Sidonian Dido kills herself with a sword that she received from Trojan Aeneas.
