The Casmonates were an ancient Ligurian people of Cisalpine Italy, known only from a single mention by Pliny the Elder.
Name The Casmonates are attested only by Pliny the Elder, among the peoples he names as the 'most renowned Ligurians' (Ligurum celeberrimi).Pliny the Elder. Naturalis Historia, 3:47.
The name is formed with the suffix -ati- and could presuppose a place-name *Casmona. The comparison with Latin Camena (from an earlier Casmena) and with Casmilla would point to an Etruscan origin.
Geography The Realencyclopädie (1899) placed the Casmonates on the northern slope of the Apennines, but noted that they cannot be precisely located.
Pliny mentions them between the Caburriates (in modern Cavour) and the Velleiates (near modern Lugagnano Val d'Arda).
