Æneas
In Greco-Roman mythology, the son of Anchises by the goddess Aphrodite (Roman Venus). He was a member of the Trojan royal family and, according to Virgil, made his way to Italy after the fall of Troy, and became the ruler of Rome (and an ancestor of the Emperor Augustus).
Both Nennius and Geoffrey of Monmouth make him the ancestor of Brutus, the first king of Britain. Dryden names him as Arthur’s ancestor in King Arthur.
