Yet vain indeed was the struggle of Cimbri and Teutones, of Marsian and Samnite, of the Pontic king and his allies in Asia and in Europe. Rome came forth from her threefold trial the undoubted mistress of all. On no corner of Mediterranean soil was there any power left that could really dispute her will. The first century before and after our æra sufficed to gather in the spoil. Enemies and allies, independent and dependent, were to be changed into subjects; kingdoms were to sink to provinces; and, if some cities once more than sceptred still kept the forms of freedom, yet chains did in truth clank over them when the Senate and People of an independent commonwealth dared only to pass such decrees as might suit the pleasure of the nearest proconsul. Of Rome’s two great rival leaders, one was to spread her dominion to the Euphrates, the other to the Channel and the Northern Sea. The Syria of Gnæus Pompeius became Rome’s richest province; but the land of old Damascus and younger Antioch could never become a Roman land. The Gaul of Gaius Cæsar became a Roman land indeed, the abiding home of Roman life and Roman culture, the land that had the praises of its cities sung by Ausonius of Bordeaux and its whole life painted for us in full by the pencil of Sidonius of Auvergne. And above all things the possession of Syria and Gaul gave Rome a new position and laid on her new duties. One aspect of the second century before our æra is that the barbarian powers of the East are again threatening. The work of Alexander and Seleukos seems half undone. Rome had weakened the arms of their successors without taking their calling on her own shoulders. As it was with the pirates, so it was with the Parthians; so it was even with the barbarians to the north of Macedonia. During the time when the Greek commonwealths and kingdoms had ceased to be really independent, but when they had not yet formally sunk to the state of Roman provinces, neither of these frontiers of the civilized world was effectually guarded. The second century before Christ was therefore a great age of barbarian advance. Again, as Mommsen puts it, the world had two lords. A power grew up on the eastern border, before which the Macedonian kings of Syria gave way, and against which Rome herself could do little more than hold her own. That Sulla was the first Roman who had direct dealings with the Parthians marks the course of things. Parthia was waxing mighty while Rome was weakening the kingdoms which might have checked the growth of Parthia. The new barbarian power lived for three hundred years after Sulla’s day to be the equal rival of Rome, in whose strife with Rome both sides could boast of victories and momentary conquests, while neither could boast of any lasting weakening of its rival. And a day came when the Parthians, who had come within the range of Greek influences, whose kings boasted themselves as φιλέλληνες, had to give way to more vigorous champions
