Strabo Geography 12.3.38

[38] There remain to be described the parts of the Pontus which lie between this country and the countries of the Amisenians and Sinopeans, which latter extend towards Cappadocia and Galatia and Paphlagonia. Now after the territory of the Amisenians, and extending to the Halys River, is Phazemonitis, which Pompey named Neapolitis, proclaiming the settlement at the village Phazemon a city and calling it Neapolis. ¹ The northern side of this country is bounded by Gazelonitis and the country of the Amisenians; the western by the Halys River; the eastern by Phanaroea; and the remaining side by my country, that of the Amaseians, which is by far the largest and best of all. Now the part of Phazemonitis towards Phanaroea is covered by a lake which is like a sea in size, is called Stephane, abounds in fish, and has all round it abundant pastures of all kinds. On its shores lies a strong fortress, Icizari, now deserted; and, near by, a royal palace, now in ruins. The remainder of the country is in general bare of trees and productive of grain. Above the country of the Amaseians are situated the hot springs of the Phazemonitae, which are extremely good for the health, and also Sagylium, with a strong hold situated on a high steep mountain that runs up into a sharp peak. Sagylium also has an abundant reservoir of water, which is now in neglect, although it was useful to the kings for many purposes. Here Arsaces, one of the sons of Pharnaces, who was playing the dynast and attempting a revolution without permission from any of the prefects, was captured and slain. ² He was captured, however, not by force, although the stronghold was taken by Polemon and Lycomedes, both of them kings, but by starvation, for he fled up into the mountain without provisions, being shut out from the plains, and he also found the wells of the reservoir choked up by huge rocks; for this had been done by order of Pompey, who ordered that the garrisons be pulled down and not be left useful to those who wished to flee up to them for the sake of robberies. Now it was in this way that Pompey arranged Phazemonitis for administrative purposes, but the later rulers distributed also ³ this country among kings.
