CALETRA an ancient city of Etruria, which appears to have ceased to exist at a very early period, but had left its name to a tract of territory called after it the Caletranus ager.(Plin. Nat. 3.5. s. 8.) The situation of this may be inferred from Livy, who tells us that the Roman colony of SATURNIA(in the valley of the Albeyna) was established in agro Caletrano,but he does not allude to the city itself (39.55).
