The Arab sources call the pass Darb maghārat al-kuḥl or al-kudjuk; the Byzantine sources either name it "Andrassos" (Ἀνδρασσός) after a nearby fortress or refer to it as the "defile called Kylindros" (Κύλινδρος).[27][28] The location has been long disputed: Schlumberger placed it in the eastern Taurus range;[29]William Mitchell Ramsay suggested identifying Andrassos with Adrasus in Isauria (modern Balabolu on Mount Adras Dağı[30]) and Kylindros with Kelenderis in Cilicia, but this was rejected by Ernst Honigmann [de] and Marius Canard as it would have placed Sayf al-Dawla's flight route by the Byzantine stronghold of Seleucia, as well as having to pass by Tarsus, whereas it is clearly stated that he fled to Syria by way of al-Massissa (Mopsuestia), further east of Tarsus;[31] Honigmann suggested identifying Andrassos with the pass still known in the early 20th century as al-Kussuk, near Çayhan,[31] but later rejected his own hypothesis, as well as that of Canard identifying it with Ince Mağara on the left bank of the Saros River.[32] The issue remains unresolved,. Themodern editors of the Tabula Imperii Byzantini [de] volume for Cappadocia consider Kylindros as an unidentified location that "must be sought on a route from Ariaratheia via Kukusos to Mopsuestia".[33]
