 Sidyma was mentioned in the 1st century BC by Alexander Polyhistor, and later by Pliny the Elder, Stephanus of Byzantium, the Synecdemus, and the "Notitiae Episcopatuum".Its extant remains are of the time of the Roman Empire, when it was an unimportant but flourishing city, and no Lycian inscriptions have been discovered there and there are no Lycian rock tombs, but its name seems to indicate an earlier origin.Above the present ruins, which lie in a valley, is a wall that may indicate the existence on the hill of a city of which no traces remain.
