After a brief return to subterranean burial in the time of Damasus the practice fell rapidly into disuse, and after A. D. 410 scarcely a single certain example can be found. In that fatal year the blast of the Gothic trumpet, startling the ear of midnight[229] in the streets of Rome, proclaimed its capture by the hosts of the stern Alaric. Amid the social and civil commotions that accompanied the breaking up of the empire, there was neither time nor means to adorn the sepulchres of the saints, and the Catacombs fell into inevitable neglect and decay. Of this year not a single sepulchral inscription remains, a striking indication of the anarchy and confusion prevailing, when even the customary honours were not paid to the dead. Like a mighty deluge sweeping away and overwhelming the art and 135 civilization of the South, came the invasion of the barbarous hordes of the North; yet like a deluge fertilizing and enriching the soil, and leaving germs of future fruitfulness behind. Having conquered the world with its arms and corrupted it with its vices, the mighty fabric of the Roman empire lost internal strength and cohesion, and began to crumble to pieces. The secret causes of its dissolution had long been stealthily at work, and its fall at last was utter and complete. Thrice in the space of three years (A. D. 408, 409, 410) Rome was besieged by the hosts of Alaric, and, in vain purchasing respite by a costly ransom, she was at last given up as a prey to the bold, eager, and greedy savagery of the North. The pillage of the world, accumulated during a thousand years of conquest, left, however, little pretext for violating the resting-places of the dead. As the rude soldiery gloated with hungry eyes on the lavish gold and silver, the precious jewels and sumptuous vestments on every side, they recked little for mere works of art, and many a porphyry vase and priceless statue was wantonly shivered by barbarian battle-axe. Nevertheless, the conqueror respected the basilicas of the apostles and the sacred vessels of their shrines, declaring that he made not war upon the saints.[230] But succeeding conquerors were less scrupulous or more rapacious. Five times in the course of the fifth century, and as often in the sixth, the Eternal City, “that was almighty named,” was besieged by her implacable foes. The churches were plundered of the massy plate and other treasures, and even the dim crypts of the Catacombs echoed the 136 clanging tread of the armed soldiery as with sacrilegious hands they stripped the shrines of the saints of their costly adorning, and rifled the graves of the dead in search for hidden treasure.[231] Each successive invasion to which Rome was exposed renewed these scenes of desecration and robbery. The Huns, the Goths, the Lombards, and, later, the Normans and Saracens, were rivals in spoliation and destruction.
