The Vandals, who, in the course of twenty years, wandered from the Elbe to the Atlas, were not a nation, not an army, not even a tribe, but a motley horde of northern barbarians, ruined provincials, and escaped slaves--a rabble whom Cæsar’s legions would have scattered like chaff, had they been as many as the sands of the shore; and yet when Genseric routed Boniface and sacked Carthage, in 439, he led barely fifty thousand fighting men. CHAPTER II THE MIDDLE AGE Probably the appreciation of the Roman monetary standard culminated during the invasion of the Huns toward the middle of the fifth century. In the reign of Valentinian III. gold sold for eighteen times its weight of silver, and Valentinian’s final catastrophe was the murder of Aëtius in 454, with whose life the last spark of vitality at the heart of Roman centralization died. The rise of Ricimer and the accession of Odoacer, mark the successive steps by which Italy receded into barbarism, and, in the time of Theoderic the Ostrogoth, she had become a primitive, decentralized community, whose poverty and sluggishness protected her from African and Asiatic competition. The Ostrogoths subdued Italy in 493, and by that date the barbarians had overrun the whole civilized world west of the Adriatic, causing the demand for money to sustain a consolidated society to cease, the volume of trade to shrink, the market for eastern wares to contract, and gold to accumulate at the centre of exchanges. As gold accumulated, its value fell, and during the first years of the sixth century it stood at a ratio to silver of less than fifteen to one, a decline of eighteen per cent.[69] As prices correspondingly rose, the pressure on the peasantry relaxed, prosperity at Constantinople returned, and the collapse of the Western Empire may have prolonged the life of the European population of the Eastern for above one hundred and fifty years. The city which Constantine planted in 324 on the shore of the Bosphorus, was in reality a horde of Roman capitalists washed to the confines of Asia by the current of foreign exchanges; and these emigrants carried with them, to a land of mixed Greek and barbarian blood, their language and their customs. For many years these monied potentates ruled their new country absolutely. All that legislation could do for them was done. They even annexed rations to their estates, to be supplied at the public cost, to help their children maintain their palaces. As long as prices fell, nothing availed; the aristocracy grew poorer day by day. Their property lay generally in land, and the same stringency which wasted Italy and Gaul operated, though perhaps less acutely, upon the Danubian peasantry also. By the middle of the fifth century the country was exhausted and at the mercy of the Huns.
