These final cities are _wholly_ intellect. Their houses are no longer, as those of the Ionic and the Baroque were, derivatives of the old peasant’s house, whence the Culture took its spring into history. They are, generally speaking, no longer houses in which Vesta and Janus, Lares and Penates, have any sort of footing, but mere premises which have been fashioned, not by blood but by requirements, not by feeling but by the spirit of commercial enterprise. So long as the hearth has a pious meaning as the actual and genuine centre of a family, the old relation to the land is not wholly extinct. But when _that_, too, follows the rest into oblivion, and the mass of tenants and bed-occupiers in the sea of houses leads a vagrant existence from shelter to shelter like the hunters and pastors of the “pre-” time, then the intellectual nomad is completely developed. This city is a world, is _the_ world. Only as a whole, as a human dwelling-place, has it meaning, the houses being merely the stones of which it is assembled. Now the old mature cities with their Gothic nucleus of cathedral, town-halls, and high-gabled streets, with their old walls, towers, and gates, ringed about by the Baroque growth of brighter and more elegant patricians’ houses, palaces, and hall-churches, begin to overflow in all directions in formless masses, to eat into the decaying country-side with their multiplied barrack-tenements and utility buildings, and to destroy the noble aspect of the old time by clearances and rebuildings. Looking down from one of the old towers upon the sea of houses, we perceive in this petrification of a historic being the exact epoch that marks the end of organic growth and the beginning of an inorganic and therefore unrestrained process of massing without limit. And now, too, appears that artificial, mathematical, utterly land-alien product of a pure intellectual satisfaction in the appropriate, the city of the city-architect. In all Civilizations alike, these cities aim at the chessboard form, which is the symbol of soullessness. Regular rectangle-blocks astounded Herodotus in Babylon and Cortez in Tenochtitlan. In the Classical world the series of “abstract” cities begins with Thurii, which was “planned” by Hippodamus of Miletus in 441. Priene, whose chessboard scheme entirely ignores the ups and downs of the site, Rhodes, and Alexandria follow, and become in turn models for innumerable provincial cities of the Imperial Age. The Islamic architects laid out Baghdad from 762, and the giant city of Samarra a century later, according to plan.[144] In the West-European and American world the lay-out of Washington in 1791 is the first big example.[145] There can be no doubt that the world-cities of the Han period in China and the Maurya dynasty in India possessed this same geometrical pattern. Even now the world-cities of the Western Civilization are far from having reached the peak of their development. I see, long after A.D.
