The review of the nations from the Danube to the Nile has exposed on every side the weakness of the Romans; and our wonder is reasonably excited that they should presume to enlarge an empire, whose ancient limits they were incapable of defending. But the wars, the conquests, and the triumphs of Justinian are the feeble and pernicious efforts of old age, which exhaust the remains of strength and accelerate the decay of the powers of life. He exulted in the glorious act of restoring Africa and Italy to the republic; but the calamities which followed the departure of Belisarius betrayed the impotence of the conqueror and accomplished the ruin of those unfortunate countries. From his new acquisitions, Justinian expected that his avarice, as well as pride, should be richly gratified. A rapacious minister of the finances closely pursued the footsteps of Belisarius; and as the old registers of tribute had been burned by the Vandals, he indulged his fancy in a liberal calculation and arbitrary assessment of the wealth of Africa. The increase of taxes, which were drawn away by a distant sovereign, and a general resumption of the patrimony or crown lands soon dispelled the intoxication of the public joy; but the emperor was insensible to the modest complaints of the people, till he was awakened and alarmed by the clamours of military discontent. Many of the Roman soldiers had married the widows and daughters of the Vandals. As their own, by the double right of conquest and inheritance, they claimed the estates which Genseric had assigned to his victorious troops. They heard with disdain the cold and selfish representations of their officers that the liberality of Justinian had raised them from a savage or servile condition; that they were already enriched by the spoils of Africa, the treasure, the slaves, and the movables of the vanquished barbarians; and that the ancient and lawful patrimony of the emperors would be applied only to the support of that government on which their own safety and reward must ultimately depend. The mutiny was secretly inflamed by a thousand soldiers, for the most part Heruli, who had imbibed the doctrines and were instigated by the clergy of the Arian sect; and the cause of perjury and rebellion was sanctified by the dispensing powers of fanaticism. The Arians deplored the ruin of their church, triumphant above a century in Africa; and they were justly provoked by the laws of the conqueror, which interdicted the baptism of their children and the exercise of all religious worship. Of the Vandals chosen by Belisarius, the far greater part, in the honours of the eastern service, forgot their country and religion. But a generous band of four hundred obliged the mariners, when they were in sight of the isle of Lesbos, to alter their course; they touched on Peloponnesus, ran ashore on a desert coast of Africa, and boldly erected on Mount Aurasius the standard of independence and revolt.
