Nomentum was a few miles farther north, between the Apennines and the Tiber, and close to the Sabine frontier.
But by far the most important of these extinct cities was Alba, on the lake to which it gave its name, which was, according to universally received tradition, the parent of Rome, as well as of numerous other cities within the limits of Latium, including Gabii, Fidenae, Collatia, Nomentum and other well-known towns.
To this period would also belong the Via Ficulensis, leading to Ficulea, and afterwards prolonged to Nomentum, and the Via Collatina, which led to Collatia.
We find that while the later (long distance) roads bear as a rule the name of their constructor, all the short distance roads on the left bank of the Tiber bear the names of towns which belonged to the league - Nomentum, Tibur, Praeneste, Labici, Ardea, Laurentumwhile Ficulea and Collatia do not appear.
Nomentum received the civitas sine suffragio after the last war of the Latins against Rome (338 B.C.); in its municipal constitution the chief magistrate even in imperial times bore the title of dictator.
