After the death of Alexander the Great, when the kingdoms of the East were divided amongst his successors, because none of the Macedonians would condescend to accept of the kingdom of the Parthians, it was delivered to Stasanor, a foreign ally. And afterwards, when the Macedonians were involved in a civil war, they, with the rest of the nations of upper Asia, followed Eumenes; and when he was defeated, they went over to Antigonus. After him, they were under Nicator Seleucus; and soon after, under Antiochus and his successors; from whose grandson Seleucus they first revolted in the First Punic War, when L. Manlius Vulso and M. Atilius Regulus were consuls. The divisions of the two brothers, Seleucus and Antiochus, procured them an immunity for this revolt, who during their contentions to wrest the sceptre out of one another’s hands, neglected to pursue the revolters. At the same time Theodotus too, the governor of the thousand cities of Bactria, revolted, and commanded himself to be called king; which example all the Eastern nations soon followed, and shook off the Macedonian yoke.
There was, at this time, one Arsaces, a man of tried valour, though of uncertain extraction. He, being accustomed to live by robbery and plunder, having heard that Seleucus had been overthrown by the Gauls in Asia, fearing the king no longer, entered the country of the Parthians with a band of robbers, defeated and killed Andragoras his lieutenant, and seized the government of the whole country. Not long after, he likewise made himself master of Hyrcania; and being now in possession of two kingdoms, he raised a great army, for fear of Seleucus and Theodotus king of the Bactrians. But being soon delivered from his fears by the death of Theodotus, he made peace and entered into an alliance with his son, who was likewise named Theodotus: and not long after, engaging with King Seleucus, who came to punish the revolters, he had a victory; and this day the Parthians observe ever since with great solemnity, as the commencement of their liberty.
Some new disturbances obliging Seleucus to return into Asia, some respite was by this means given to Arsaces, who took this opportunity to establish the Parthian government, levy soldiers, fortify castles, and secure the fidelity of his cities. He built a city too, called Dara, upon the mountain Zapaortenon; which was so situated that no city could be stronger or pleasanter. For it was so environed with rough rocks on all sides, that it needed no garrison to defend it; and so fertile was the adjacent soil, that it was abundantly furnished with all necessaries by its own riches. Then there were in such plenty woods and fountains, that there was never any scarcity of water; and it had vast store of game. Thus Arsaces, having at once acquired and established a kingdom, was no less memorable among the Parthians than Cyrus among the Persians, Alexander among the Macedonians, or Romulus among the Romans; and he died in a good old age. To his memory the Parthians paid this honour, that from him they called all their kings by the name of Arsaces. His son and successor in the kingdom, who was Arsaces by name, fought with great bravery against Antiochus the son of Seleucus, who came against him with a hundred thousand foot and twenty thousand horse; and at last made an alliance with him. The third king of the Parthians was Priapatius; but he too was named Arsaces; for, as was said above, they called all their kings by that name, as the Romans do theirs Cæsar and Augustus. He died, after he had reigned fifteen years, leaving two sons, Mithridates and Phraates, the elder of whom, Phraates, being according to the custom of this nation heir of the kingdom, subdued by his arms the Mardians, a strong nation, and died not long after, leaving several sons behind him, whom he passed by, and left his kingdom to his brother Mithridates, a man of uncommon abilities; judging that more was due to the name of king than that of father; and that he ought to prefer the interest of his country to the grandeur of his children.
