Truentus
Τρουεντῖνος
Truentus or TRUENTINUS (Τρουεντῖνος: Tronto), a considerable river of Picenum, which rises in the Apennines above Amatrice, flows under the walls of Ascoli (Asculum), and falls into the Adriatic about 5 miles S. of S. Benedetto. It gave name to a town which was situated at its mouth, and is called by Pliny Truentum, but more commonly CASTRUM TRUENTINUM Though one of the most considerable of the rivers of Picenum, the Truentus has very much the character of a mountain torrent, and is only navigable for about 5 miles near its mouth. (Strab. v. p.241; Plin. Nat. 3.13. s. 18; Mel. 2.4.6; Ptol. 3.1.21.)
