Thence had come all the vast schemes such as the cyclopean quays and the mere ministries struggling to outvie the Colosseum; and thence had come all the new districts of gigantic houses which had sprouted like towns around the ancient city.

It was not only on the castle fields, but at the Porta San Giovanni, the Porta San Lorenzo, the Villa Ludovisi, and on the heights of the Viminal and the Esquiline that unfinished, empty districts were already crumbling amidst the weeds of their deserted streets.

After two thousand years of prodigious fertility the soil really seemed to be exhausted.

Even as in very old fruit gardens newly planted plum and cherry trees wither and die, so the new walls, no doubt, found no life in that old dust of Rome, impoverished by the immemorial growth of so many temples, circuses, arches, basilicas, and churches.

And thus the modern houses, which men had sought to render fruitful, the useless, over-huge houses, swollen with hereditary ambition, had been unable to attain maturity, and remained there sterile like dry bushes on a plot of land exhausted by over-cultivation.
