That in these statements I do not exaggerate, hear what Tacitus says: "The holy ceremonies of religion were violated; adultery reigning without control; the adjacent islands filled with exiles; rocks and desert places stained with clandestine murders, and Rome itself a theatre of horrors, where nobility of descent and splendour of fortune marked men out for destruction; where the vigour of mind that aimed at civil dignities, and the modesty that declined them, were offences without distinction; where virtue was a crime that led to certain ruin; where the guilt of informers and the wages of their iniquity were alike detestable; where the sacerdotal order, the consular dignity, the government of provinces, and even the cabinet of the prince, were seized by that execrable race as their lawful prey; where nothing was sacred, nothing safe from the hand of rapacity; where slaves were suborned, or by their own malevolence excited against their masters; where freemen betrayed their patrons, and he who had lived without an enemy died by the treachery of a friend." [Sidenote: Effects in the provinces. Free trade.] [Sidenote: Intellectual advancements.] But, though these were the consequences of the concentration of power and wealth in the city of Rome, it was otherwise in the expanse of the empire. The effect of Roman domination was the cessation of all the little wars that had heretofore been waged between adjacent peoples. They exchanged independence for peace. Moreover, and this, in the end, was of the utmost importance to them all, unrestricted commerce ensued, direct trade arising between all parts of the empire. The Mediterranean nations were brought closer to each other, and became common inheritors of such knowledge as was then in the world. Arts, sciences, improved agriculture, spread among them; the most distant countries could boast of noble roads, aqueducts, bridges, and great works of engineering. In barbarous places, the legions that were intended as garrisons proved to be foci of civilization. For the provinces, even the wickedness of Rome was not without some good. From one quarter corn had to be brought; from another, clothing; from another, luxuries; and Italy had to pay for it all in coin. She had nothing to export in return. By this there was a tendency to equalization of wealth in all parts of the empire, and a perpetual movement of money. Nor was the advantage altogether material; there were conjoined intellectual results of no little value. Superstition and the amazing credulity of the old times disappeared. In the first Punic War, Africa was looked upon as a land of monsters; it had serpents large enough to stop armies, it had headless men. Sicily had its Cyclops, giants, enchantresses; golden apples grew in Spain; the mouth of Hell was on the shores of the Euxine. The marches of the legions and the voyages of merchants made all these phantasms vanish. [Sidenote: Disappearance of the Roman ethnical element.]
