in Ancient Geography, a colony from Lavinium, in Latium, fifteen miles south-east from Rome, established by Ascanius, the son of Æneas, at the foot of the Mons Albanus. It was called Alb, from a white sow found by Æneas, which farrowed thirty white pigs on that spot; which circumstance was interpreted to portend the building of a city there in thirty years after. (Propertius.) The epithet Longa was added on account of its length. It was the royal residence till the building of Rome, as was foretold by Anchises, (Virgil); was destroyed by Tullius Hostilius, all but the fane or temple; and the inhabitants were transplanted to Rome. (Strabo.)
