Short answers, pulled from the story.
Aeneas was a Trojan hero born from the union of the goddess Aphrodite and the mortal prince Anchises. His name derived from the Greek word for terrible, reflecting the sorrow of his divine mother who foresaw the grief of loving a mortal man.
Aeneas escaped the burning city of Troy by carrying his father Anchises on his back after Zeus struck Anchises lame with a thunderbolt. This act of carrying his father through the flames became the defining image of his piety and duty.
Aeneas entered into a year-long affair with Queen Dido, also known as Elissa, before being compelled to leave by the messenger god Mercury. Dido committed suicide by stabbing herself with the sword Aeneas had given her, which sealed the fate of two great civilizations and created an enmity that culminated in the Punic Wars.
Jupiter agreed to make Aeneas immortal after Venus asked for his son's deification, and the river god Numicus cleansed Aeneas of all his mortal parts. Venus anointed him with ambrosia and nectar, and Aeneas was recognized as the god Jupiter Indiges worshipped by the Roman people.
In the Middle Ages, Aeneas was reinterpreted in new ways such as in the Prose Edda where Snorri Sturlason told of a Trojan named Munon who fathered a son identical to Thor. The 12th-century French Roman d'Enéas addressed Aeneas's sexuality while later accounts by Guido delle Colonne suggested his departure from Troy was a reward for treason.
