TREVENTUM or TEREVENTUM( Eth. Treventinas, Plin.; but inscriptions have Terventinas and Tereventinas: Trivento), a town of Samnium, in the country of the Pentri, situated on the right bank of the Trinius ( Trigno), not far from the frontiers of the Frentani. Its name is not noticed in history, but Pliny mentions it among the municipal towns of Samnium in his time: and we learn from the Liber Coloniarum that it received a Roman colony, apparently under the Triumvirate (Plin. Nat. 3.14. s. 17; Lib. Colon. p. 238). It is there spoken of as having been thrice besieged ( ager ejus . . . post tertiam obsidionem adsignatus est), probably during the Social War and the civil wars that followed; but we have no other account of these sieges; and the name is not elsewhere mentioned. But from existing remains, as well as inscriptions, it appears to have been a place of considerable importance, as well as of municipal rank. The modern Trivento, which is still the see of a bishop and the capital of the surrounding district, stands on a hill above the river Trigno, but the ruins of ancient buildings and fragments of masonry are scattered to a considerable extent through the valley below it. (Romnanelli, vol. 2. p. 473.) The inscriptions which have been discovered there are given by Mommsen ( Inscr. R. N. pp. 269, 270).
