Faliscans

Falisci (Ancient Greek: Φαλίσκοι) is the ancient Roman exonym for an Italic people who lived in what is now northern Lazio, on the Etruscan side of the Tiber River. They spoke an Italic language, Faliscan, closely akin to Latin. Originally a sovereign state, politically and socially they supported the Etruscans, joining the Etruscan League. This conviction and affiliation led to their ultimate near destruction and total subjugation by Rome.

Only one instance of their own endonym has been found to date: an inscription from Falerii Novi from the late 2nd century AD refers to the falesce quei in Sardinia sunt, "the Faliscans who are in Sardinia", where falesce is the nominative plural case. An Etruscan inscription calls them the feluskeś. The Latin cannot be far different from the original name. The -sc- suffix is "distinctive of the Italic ethnonyms".

The Falisci resided in a region called by the Romans the Ager Faliscus, "Faliscan Country", located on the right bank of the Tiber River between and including Grotta Porciosa in the north and Capena in the south. To the west, the corners of the roughly square area were on the slopes of the Monti Sabatini in the south and the Monti Cimini in the north. Pollen samples from Lake Bracciano, Lake Monterosi and Lake Vico reveal that the montane forests, formed by oaks, were very dense until the 2nd century BC.

The arable land was contained within an enclosure of volcanic highlands and the Tiber River. The northern border of the enclosure went along the ridge of the Monti Cimini, the southern along the ridge connecting the Monti Sabatini and Monte Soratte, the westen along the highlands connecting the two large volcanic lakes. The inner slopes are drained by streams pointing at the Tiber, which collect into converging canyons and finally into the canyon of the Treia River, which empties into the Tiber. These streams required an extensive network of bridges.
