Wherefore he immediately killed his father, thinking he would never die. He likewise killed all his thirty brothers. Neither did his cruelty stop there: for finding he was hated by the nobility for his daily barbarities, he ordered his son, who was almost grown up to the years of maturity, to be slain; that there might none be left to be proclaimed king. Antony made war upon him with sixteen very able legions, because he had furnished assistance against him and Cæsar; but being sadly mauled in several battles, he fled from Parthia. This victory making Phraates insupportably insolent and cruel, he was forced by his people into banishment. After he had for a long time wearied the neighbouring states, and at last the Scythians too, with his importunity, he was restored to his kingdom by a powerful assistance from the Scythians. In his absence, the Parthians had made one Tiridates their king, who hearing of the approach of the Scythians, fled with a great body of his friends to Cæsar, at that time waging war with Spain, bringing the youngest son of Phraates as hostage to Cæsar, whom being negligently guarded he had stolen away. Upon this news, Phraates immediately sent ambassadors to Cæsar, and demanded that his son, together with his vassal Tiridates, should be sent back to him.
Cæsar, having given audience to the ambassadors of Phraates and heard the reasons of Tiridates, who desired to be restored to his crown, declaring that the kingdom of Parthia would be in a manner subject to the Romans if he held it from them, said that he would neither surrender Tiridates to the Parthians, nor give assistance to Tiridates against the Parthians. However, that he might not seem to refuse them everything they demanded, he sent Phraates his son to him, without any ransom, and ordered a handsome maintenance for Tiridates, so long as he had a mind to continue amongst the Romans. After this, the Spanish War being ended, when he came into Syria to settle the state of the East, Phraates was afraid that he might have some designs upon Parthia. Wherefore the prisoners who had been taken at the defeat of Crassus and Antony were gathered together, and they, together with the military standards either of them had lost, were sent back to Augustus. Nor was this all, but the sons and grandsons of Phraates were likewise delivered as hostages to Augustus. And thus Augustus did more by the terror of his name than any other general could have done by his arms.[b]
Modern Accounts of Parthia
This is the history of the Parthians as given by Justin in his abridgement of the lost work of Trogus Pompeius. Later investigations and criticism have thrown a little light on various portions of the history, and from the point where Justin grows briefest other Roman historians took up the chronicles of the Parthians with avid interest. The study of coins has also been of invaluable aid. It has seemed better to give Justin’s account in its original fluency without interpolating criticisms here and there. Now, however, we must make a brief presentation of Parthian history from the start in a modern view.[a]
THE PARTHIAN EMPIRE
[261-241 B.C.]
Hellenism made no deep impression on Iran as on the West, nor did the loose-jointed empire attain to anything higher than a Hellenistic reproduction of the kingdom of the Achæmenians. Even in the fragmentary records that we possess we hear from the first of rebellions little favourable to consolidation of the realm; Seleucus, like Alexander, still had an army of Macedonians and Persians together, while the later Seleucids, at least in their western wars, used natives sparingly and only as bowmen, slingers, or the like, and preferred for these services the wild desert and mountain tribes of Iran.
Under the weak Antiochus II northeastern Iran was lost to the empire. While the Seleucids were busy elsewhere, probably in the long war with Ptolemy Philadelphus, which occupied Antiochus’ later years, Diodotus, viceroy of Bactria, took the title of king. The new kingdom included Sogdiana and Margiana from the first, while the rest of the East, with a single exception scarcely noticed at the time, adhered to the Seleucids. Now the formation of a strong local kingdom, heartily supported by the Greek colonies and likely to control the neighbouring nomads and strictly to protect its own frontiers, was by no means agreeable to the chief of the desert tribes who, like the modern Turkomans, had been wont to pillage the settled lands and raise blackmail with little hindrance from the weak and distant central authority at Antioch. Accordingly two brothers, Arsaces and Tiridates—whose tribe, the Parnians, a subdivision of the Dahæ, had hitherto pastured their flocks in Bactria on the banks of the Ochus—moved west into Seleucid territory near Parthia. An insult offered to the younger brother by the satrap Pherecles moved them to revolt; Pherecles was slain, and Parthia freed from the Macedonians.
