Nicator (312-208 B.C.), until the Mithridates again gained control up to 63 B.C., when upon the final dissolution of their empire, Pontus, under the Romans, entered upon a new period of life. From that time there was sent there by them annually a special governor until in 46 B.C. Polemon from Tralles in Phrygia was established as king of Pontus from Bosporus to Colchis. Many of the coast cities which had been the allies of the Romans during the wars waged by them from 89-63 B.C. against Mithridates VII, called Eupator, and among them Trapezus, were, however, still left autonomous. The Polemoniac Empire lasted till 63 A.D., when Nero made Pontus a Roman province. After a short period of decline Trapezus rose again in the time of Julian in 333. It had accepted Christianity from the first apostle, Andrew, who came there from Samsun in 34 A.D. and transmitted it to the surrounding peoples. Its first bishop was Eugeneos, known as the patron and protector of the city, who endured martyrdom in 216 under the reign of Diocletian (a Byzantine church, still existing, preserves his name). He was succeeded by a long line of bishops who honored the Church. In fact, some of them participated in Ecumenical Synods. In the time of the great Constantine, Trapezus continued to be a provincial city under a pro-consul, as also in the time of Justinian (6th century). As such it belonged, along with Cerasus, to Polemoniac Pontus, the capital of which was then Neocæsarea. From then up to the time of Leo the Isaurian, unfortunately, we know nothing about it, but in the time of the Isaurians it appears as a starting point for political and warlike operations undertaken against the Persians, the Turcomans and the Arabs, having become the metropolis of the large and important “thema” (district) of Chaldia, while it was, at the same time, and even before the time of the Isaurians, a home of learning, as the Siracene Ananias, a trustworthy Armenian writer of the 7th century, testifies.
