Strabo Geography 12.3.41

[41] After Pompeiupolis comes the remainder of the interior of Paphlagonia, extending westwards as far as Bithynia. This country, small though it is, was governed by several rulers a little before my time, but, the family of kings having died out, it is now in possession of the Romans. At any rate, they give to the country that borders on Bithynia ¹ the names “Timonitis,” “the country of Gezatorix,” and also “Marmolitis,” “Sanisene,” and “ Potamia. There was also a Cimiatene, in which was Cimiata, a strong fortress situated at the foot of the mountainous country of the Olgassys. This was used by Mithridates, surnamed Ctistes, ² as a base of operations when he established himself as lord of Pontus; and his descendants preserved the succession down to Eupator. The last to reign over Paphlagonia was Deïotarus, the son of Castor, surnamed Philadelphus, who possessed Gangra, the royal residence of Morzeüs, which was at the same time a small town and a fortress.

[41] Next to Pompeiopolis is the remainder of the inland parts of Paphlagonia as far as Bithynia towards the west. This tract, although small in extent, was governed, a little before our time, by several princes, but their race is extinct; at present it is in possession of the Romans. The parts bordering upon Bithynia are called Timonitis; the country of Gezatorix, Marmolitis, Sanisene, and Potamia. There was also a Cimiatene, in which was Cimiata, a strong fortress situated at the foot of the mountainous range of the Olgassys. Mithridates, surnamed Ctistes, (or the Founder,) made it his head-quarters when engaged in the conquest of Pontus, and his successors kept possession of it to the time of Mithridates Eupator. The last king of Paphlagonia was Deïotarus, ¹ son of Castor, and surnamed Philadelphus, who possessed Gangra, ² containing the palace of Morzeus, a small town, and a fortress.
