TEARUS(Plin. Nat. 4.11. s. 18; Τέαρος, Hdt. 4.90), now Teare, Deara, or Dere, a river in the SE. of Thrace, flowing in a SW. direction, until it joins the Contadesdos, their united waters falling into the Agrianes, one of the principal eastern tributaries of the Hebrus. Herodotus (l. c.) states that the sources of the Tearus are equidistant from Heraeum on the Propontis and Apollonia on the Euxine; that they are thirty-eight in number; and that, though they all issue from the same rock, some of them are cold, others warm. Their waters had the reputation, among the neighbouring people, of being pre-eminently medicinal, especially in cases of itch or mange (ψώρη). On his march towards the Danube, Darius halted his army for three days at the sources of the Tearus, and erected a pillar there, with an inscription commemorative of their virtues, and of his own.
