Isis
ὁ Ἴσις
Isis (ὁ Ἴσις), a navigable river on the east coast of the Euxine between the Acinasis and Mogrus, from each of which its distance amounted to 90 stadia, while its mouth was 180 stadia south of that of the Phasis. (Arrian, Peripl. p. 7; Plin. Nat. 6.4; Scylax, p. 32, where the common reading Ἴρις has been corrected by Gail.) This river is believed to be the modern Tshorok.
