The small province of Commagene between Syria and Cappadocia with its capital Samosata (Samsat) remained a dependent kingdom in the hands of the already-named Seleucid Antiochus;( 21) to him too were assigned the important fortress of Seleucia (near Biradjik) commanding the more southern passage of the Euphrates, and the adjoining tracts on the left bank of that river; and thus care was taken that the two chief passages of the Euphrates with a corresponding territory on the eastern bank were left in the hands of two dynasts wholly dependent on Rome.

Alongside of the kings of Cappadocia and Commagene, and in real power far superior to them, the new king Deiotarus ruled in Asia Minor.

One of the tetrarchs of the Celtic stock of the Tolistobogii settled round Pessinus, and summoned by Lucullus and Pompeius to render military service with the other small Roman clients, Deiotarus had in these campaigns so brilliantly proved his trustworthiness and his energy as contrasted with all the indolent Orientals that the Roman generals conferred upon him, in addition to his Galatian heritage and his possessions in the rich country between Amisus and the mouth of the Halys, the eastern half of the former Pontic empire with the maritime towns of Pharnacia and Trapezus and the Pontic Armenia as far as the frontier of Colchis and the Greater Armenia, to form the kingdom of Lesser Armenia.

Soon afterwards he increased his already considerable territory by the country of the Celtic Trocmi, whose tetrarch he dispossessed.

Thus the petty feudatory became one of the most powerful dynasts of Asia Minor, to whom might be entrusted the guardianship of an important part of the frontier of the empire.
Princes and Chiefs Vassals of lesser importance were, the other numerous Galatian tetrarchs, one of whom, Bogodiatarus prince of the Trocmi, was on account of his tried valour in the Mithradatic war presented by Pompeius with the formerly Pontic frontier-town of Mithradatium; Attalus prince of Paphlagonia, who traced back his lineage to the old ruling house of the Pylaemenids; Aristarchus and other petty lords in the Colchian territory; Tarcondimotus who ruled in eastern Cilicia in the mountain-valleys of the Amanus; Ptolemaeus son of Mennaeus who continued to rule in Chalcis on the Libanus; Aretas king of the Nabataeans as lord of Damascus; lastly, the Arabic emirs in the countries on either side of the Euphrates, Abgarus in Osrhoene, whom the Romans endeavoured in every way to draw over to their interest with the view of using him as an advanced post against the Parthians, Sampsiceramus in Hemesa, Alchaudonius the Rhambaean, and another emir in Bostra.
Priestly Princes To these fell to be added the spiritual lords who in the east frequently ruled over land and people like secular dynasts, and whose authority firmly established in that native home of fanaticism the Romans prudently refrained from disturbing, as they refrained from even robbing the temples of their treasures: the high-priest of the Goddess Mother in Pessinus; the two high-priests of the goddess Ma in the Cappadocian Comana (on the upper Sarus) and in the Pontic city of the same name (Gumenek near Tocat), both lords who were in their countries inferior only to the king in power, and each of whom even at a much later period possessed extensive estates with special jurisdiction and about six thousand temple-slaves--Archelaus, son of the general of that name who passed over from Mithradates to the Romans, was invested by Pompeius with the Pontic high-priesthood--the high-priest of the Venasian Zeus in the Cappadocian district of Morimene, whose revenues amounted annually to 3600 pounds (15 talents); the "archpriest and lord" of that territory in Cilicia Trachea, where Teucer the son of Ajax had founded a temple to Zeus, over which his descendants presided by virtue of hereditary right; the "arch-priest and lord of the people" of the Jews, to whom Pompeius, after having razed the walls of the capital and the royal treasuries and strongholds in the land, gave back the presidency of the nation with a serious admonition to keep the peace and no longer to aim at conquests.
Urban Communities Alongside of these secular and spiritual potentates stood the urban communities.
