Surviving Destroyed or barely existing The Zygii (Ancient Greek: Ζυγοί, Zygoí) or Zygians were described by Strabo as a nation to the north of Colchis.

And above these are situated the narrow passes of the Phtheirophagi (Phthirophagi); and after the Heniochi the Colchian country, which lies at the foot of the Caucasian, or Moschian, Mountains.

To the north was Sarmatian territory, and to the south lay the part of Colchis inhabited by the Svans (Soanes of Strabo and Pliny the Elder).

Initially, Zyx (Italian: Sychia, Georgian: ჯიქეთი, Jiqeti) in Greek literature referred to a people inhabiting the area between Gagra and Tuapse, who later expanded up to the estuary of the Kuban and the neighbouring region of historical Tmutarakan.

[2] This tribe also features in several ancient and medieval works, notably in Pliny (Zichoi), Constantine VII Porphyrogennetos, medieval Georgian chroniclers (Georgian: ჯიქები, Jikebi), Marco Polo, and Johannes de Galonifontibus, who, in his Libellus de notitia orbis, speaks of "Zikia or Circassia" and their language, perhaps the earliest reference to the Northwest Caucasian languages.
