By the first century BCE some sort of coherence was reached by constructing a complicated family tree, which linked Aeneas and Romulus, and at the ‘right’ dates: Aeneas became seen as the founder not of Rome but of Lavinium; his son Ascanius was said to have founded Alba Longa – the city from which Romulus and Remus were later cast out before they founded Rome; and a shadowy and, even by Roman standards, flagrantly fictional dynasty of Alban kings was constructed to bridge the gap between Ascanius and the magic date of 753 BCE. This is the version that Livy endorses.
