TRAENS or TRAÏS (Τράειςor Τράενς,—εντος : Trionto), a river of Bruttium celebrated for the sanguinary defeat of the Sybarites on its banks by their rivals the Crotoniats, which led to the destruction of the city of Sybaris, B.C. 510. (Iambl. Vit. Pyth. § 260.) It is singular that the banks of a stream which had been the scene of such a catastrophe should be again selected by the remnant of the Sybarites who were expelled from the new colony of Thurii shortly after its foundation [THURII] for the site of their settlement. They, however, did not remain long, being expelled and put to the sword by the neighbouring barbarians, whom Diodorus by a remarkable anachronism calls Bruttians, apparently within a few years of their establishment. (Diod. 12.22.) The name of the river is not found in any of the geographers, but there can be little doubt of its being the one still called the Trionto, which falls into the gulf of Tarentum a few miles E. of Rossano, and gives name also to an adjoining headland, the Capo di Trionto.
