The ancient name of the river is the Thermodon, and the surrounding region was the
Pontus.[4] In antiquity, its mouth was about "three plethra" wide (ca. 300 feet[5]), and it was navigable.[1][6] The river, said by
Strabo to have "its many sources near Phanaroea... [in] many streams" (which is not true; perhaps he was thinking of the Iris), was "very often noticed by ancient writers", and its mouth was near the town of
Themiscyra.[1] Starting with
Dionysius Periegetes, in his Periegesis of the World, the Thermodon is often confused with the
Iris River (modern Yeşilırmak), which is much larger, flows through
Phanaroea, and carries much more sediment.[7]
