Julus

Ascanius (/əˈskeɪniəs/) (said to have reigned 1176-1138 BC) a legendary king of Alba Longa and is the son of the Trojan hero Aeneas and Creusa, daughter of Priam. He is a character in Roman mythology, and has a divine lineage, being the son of Aeneas, who is the son of the goddess Venus and the hero Anchises, a relative of the king Priam; thus Ascanius has divine ascendents by both parents, being descendant of god Jupiter, his wife Juno and Dardanus. He is also an ancestor of Romulus, Remus and the Gens Julia. Together with his father, he is a major character in Virgil's Aeneid, and he is depicted as one of the founders of the Roman race.

In Greek and Roman mythology, Ascanius was the son of the Trojan prince Aeneas and Creusa, daughter of Priam. After the Trojan War, as the city burned, Aeneas escaped to Latium in Italy, taking his father Anchises and his child Ascanius with him, though Creusa died during the escape.
