Latium and Campania together comprise Region I, of which Latium is divided into Latium Vetus or Antiquus and Latium Adiectum or Novum.It included the Hernican cities of Anagnia, Ferentinum, Aletrium, and Verulae, a group of mountain strongholds on the north side of the valley of the Trerus (Sacco); together with the Volscian cities on the south of the same valley, and in that of the Liris, the whole of which, with the exception of its extreme upper end, was included in the Volscian territory.Here were situated Signia, Frusino, Fabrateria, Fregellae, Sora, Arpinum, Atina, Aquinum, Casinum, and Interamna; Anxur (Terracina) was the only seaport that properly belonged to the Volscians, the coast from there to the mouth of the Liris being included in the territory of the Aurunci, or Ausones as they were termed by Greek writers, who possessed the maritime towns of Fundi, Formiae, Caieta, and Minturnae, together with Suessa in the interior, which had replaced their more ancient capital of Aurunca.
