As it became the fashion in the later times of the Republic to claim a divine origin for the most distinguished of the Roman gentes, it was contended that Iulus, the mythical ancestor of the race, was the same as Ascanius, the son of Aeneas, and founder of Alba Longa. Aeneas was, in turn, the son of Venus and Anchises. In order to prove the identity of Ascanius and Iulus, recourse was had to etymology, some specimens of which the reader curious in such matters will find in Servius. Other traditions held that Iulus was the son of Aeneas by his Trojan wife, Creusa, while Ascanius was the son of Aeneas and Lavinia, daughter of Latinus.
