Aeneas, the son of Aphrodite and the mortal Anchises, is one of the most important Trojan warriors. Aeneas has two significant appearances in Homer's Iliad. The first comes in Iliad 5.166-351, where he tries to make a stand against the Greek warrior Diomedes, who is going on a major rampage. Homer says that "Aeneas would have died" if Aphrodite would not have rescued him. So bold was Diomedes that he even attacked and wounded Aphrodite.
Aeneas' next major appearance occurs in Iliad 20. In this book, Apollo inspires a reluctant Aeneas to battle Achilles. When the two warriors encounter one another, Achilles recalls how they had met another time in battle, but that Aeneas was "saved by Zeus and the other gods" (Kline translation). Once again, Achilles was on the verge of getting the best of Aeneas, but the gods again intervene because, as Poseidon notes, "Aeneas is destined to live on". Thus, Poseidon rescues Aeneas and whisks him away from the thick of the battle.
As gcarden498 notes, Aeneas managed to survive the fall of Troy and goes on to become one of the founders of Rome.
Aeneas is the only Trojan to escape from the city of Troy before it was destroyed by the Greeks. His adventures take him to Carthage where Queen Dido falls in love with him. She later committed suicide when Aeneas abandoned her. The epic poem, The Aeneid is devoted to the adventures of Aneas and his founding of Rome.
