This revolution in the relations of the peoples in the interior of Asia is the turning-point in the history of antiquity. The tide of national movement, which had hitherto poured from the west to the east and had found in Alexander the Great its last and highest expression, was followed by the ebb. On the establishment of the Parthian state not only were such Hellenic elements, as may still perhaps have been preserved in Bactria and on the Indus, lost, but western Iran also relapsed into the track which had been abandoned for centuries but was not yet obliterated. The Roman senate sacrificed the first essential result of the policy of Alexander, and thereby paved the way for that retrograde movement, whose last offshoots ended in the Alhambra of Granada and in the great Mosque of Constantinople. So long as the country from Ragae and Persepolis to the Mediterranean obeyed the king of Antioch, the power of Rome extended to the border of the great desert; the Parthian state could never take its place among the dependencies of the Mediterranean empire, not because it was so very powerful, but because it had its centre far from the coast, in the interior of Asia. Since the time of Alexander the world had obeyed the Occidentals alone, and the east seemed to be for these merely what America and Australia afterwards became for the Europeans; with Mithradates I the east re-entered the sphere of political movement. The world had again two masters. Maritime Relations Piracy It remains that we glance at the maritime relations of this period; although there is hardly anything else to be said, than that there no longer existed anywhere a naval power. Carthage was annihilated; the war-fleet of Syria was destroyed in accordance with the treaty; the war-marine of Egypt, once so powerful, was under its present indolent rulers in deep decay. The minor states, and particularly the mercantile cities, had doubtless some armed transports; but these were not even adequate for the task--so difficult in the Mediterranean--of repressing piracy. This task necessarily devolved on Rome as the leading power in the Mediterranean. While a century previously the Romans had come forward in this matter with especial and salutary decision, and had in particular introduced their supremacy in the east by a maritime police energetically handled for the general good,(40) the complete nullity of this police at the very beginning of this period as distinctly betokens the fearfully rapid decline of the aristocratic government. Rome no longer possessed a fleet of her own; she was content to make requisitions for ships, when it seemed necessary, from the maritime towns of Italy, Asia Minor, and elsewhere. The consequence naturally was, that buccaneering became organized and consolidated. Something, perhaps, though not enough, was done towards its suppression, so far as the direct power of the Romans extended, in the Adriatic and Tyrrhene seas.
