Zygii

The Zygii (Greek: Ζυγοί/Zygoi) or Zygians, were described by Strabo as a nation to the north of Colchis. He wrote:

And on the sea lies the Asiatic side of the Bosporus, or the Syndic territory. After this latter, one comes to the Achaei and the Zygii and the Heniochi, and also the Cercetae and the Macropogones. 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. (Strabo, Geographica 11.2)

William Smith observes that "they were partly nomad shepherds, partly brigands and pirates, for which latter vocation they had ships specially adapted". They inhabited the region known as Zyx, which is on the northern slopes of the Caucasus east of Elbrus. To the east were the Avars, and to the west were the Circassians. 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).
