Several of the Latin cities, including Tibur and Praeneste, were situated on the terrace-like underfalls of these mountains, 2 while Cora, Norba and Setia were placed in like manner on the slopes of the Volscian mountains (Monti Lepini), a rugged and lofty limestone range, which runs parallel to the main mass of the Apennines, being separated from them, however, by the valley of the Trerus (Sacco), and forms a continuous barrier from there to Terra.cina.
Satricum, on the other hand, was certainly south of the Alban Hills, between Velitrae and Antium; while Cora, Norba and Setia (all of which retain their ancient names with little modification) crowned the rocky heights which form advanced posts from the Volscian mountains towards the Pontine Marshes.
Other cities of the Latin league had already (according to the traditional dates) received Latin colonies - Velitrae (494 B.C.), Norba (492), Ardea (442), Labici (418), Circei (393), Satricum (385), Setia (382).
There must too have been a road, along the line of the later Via Appia, to Bovillae, Aricia, Lanuvium and Velitrae, going thence to Cora, Norba and Setia along the foot of the Volscian Mountains; while nameless roads, which can still be traced, led direct from Rome to Satricum and to Lavinium.
It is doubtful, however, if Alcantara marks the site of any Roman town, though archaeologists have sometimes identified it either with Norba Caesarea or with Interamnium.
