After Sidene one comes to Pharnacia, a fortified town; and afterwards to Trapezus, a Greek city, to which the voyage from Amisus is about two thousand two hundred stadia. Then from here the voyage to Phasis is approximately one thousand four hundred stadia, so that the distance from Hieron1
to Phasis is, all told, about eight thousand stadia, or slightly more or less. As one sails along this seaboard from Amisus, one comes first to the Heracleian Cape, and then to another cape called Jasonium, and to Genetes, and then to a town called Cytorus,2
from the inhabitants of which Pharnacia was settled, and then to Ischopolis, now in ruins, and then to a gulf, on which are both Cerasus and Hermonassa, moderate-sized settlements, and then, near Hermonassa, to Trapezus, and then to Colchis. Somewhere in this neighborhood is also a settlement called Zygopolis. Now I have already described3
Colchis and the coast which lies above it.
