Tarsius
Τάρσιος
Tarsius (Τάρσιος), a river of Mysia in the neighbourhood of the town of Zeleia, which had its source in Mount Temnus, and flowed in a northeastern direction through the lake of Miletopolis, and, issuing from it, continued its north-eastern course till it joined the Macestus. (Strab. xiii. p. p. 587.) Strabo indeed states that the river flowed in numerous windings not far from Zeleia; but he can scarcely mean any other river than the one now bearing the name Balikesri, and which the Turks still call Tarza. Hamilton (Researches, vol. ii. p. 106) identifies it with the Kara Su or Kara Dere Su, which flows into Lake Maniyas.
