Chadisia (Ancient Greek: Χαδισία), also Chadisius or Chadisios (Χαδίσιος), was a town of ancient Pontus, not far from the coast on a river of the same name.[1][2]Hecataeus, quoted by Stephanus of Byzantium, speaks of Chadisia as a city of the Leucosyri, that is, of the group the Persians called the Cappadocians; and he says, "the plain Themiscyra extends from Chadisia to the Thermodon." Menippus, in his Periplus of the two Ponti, also quoted by Stephanus, says: "from the Lycastus to the village and river Chadisius is 150 stadia, and from the Chadisius to the river Iris 100 stadia."[1]
