(Θήχης; Thḗchēs). Mountain ridge in the east of the northern Anatolian peripheral mountain chain (Xen. An. 4,7,21; Diod. Sic. 14,29,3: τὸ Χήνιον ὄρος/tò Chḗnion óros). It was from here that the 'Ten Thousand' of Xenophon's Anábasis on their retreat after the battle of Cunaxa (in the autumn of 401 BC), saw the sea again for the first time (here: the Black Sea; Pontos Euxeinos). The T. can probably be located in the area of the Zigana Pass (Zigana Geçidi, 2025 m elevation).
