With the fall of Babylon, the sceptre of dominion, borne for so many years by Semitic princes, was given into the hands of the Aryan peoples, who were destined, from this time forward, to shape the course of events, and control the affairs of civilization. THE GREAT EDIFICES OF BABYLON.--The deep impression which Babylon produced upon the early Greek travellers was made chiefly by her vast architectural works,--her temples, palaces, elevated gardens, and great walls. The Hanging Gardens of Nebuchadnezzar and the walls of the city were reckoned among the wonders of the world. [Illustration: BIRS-NIMRUD. (Ruins of the great Temple of the Seven Spheres, near Babylon.)] The Babylonians, like their predecessors the Chaldæans, accorded to the sacred edifice the place of pre-eminence among their architectural works. Sacred architecture in the time of Nebuchadnezzar had changed but little from the early Chaldæan models (see p. 44); save that the temples were now larger and more splendid, being made, in the language of the inscriptions, "to shine like the sun." The celebrated Temple of the Seven Spheres, at Borsippa, a suburb of Babylon, may serve as a representative of the later Babylonian temples. This structure was a vast pyramid, rising in seven consecutive stages, or platforms, to a height of over one hundred and fifty feet. Each of the stages was dedicated to one of the seven planets, or spheres. (The sun and moon were reckoned as planets.) The stages sacred to the sun and moon were covered respectively with plates of gold and silver. The chapel, or shrine proper, surmounted the uppermost stage. An inscribed cylinder discovered under the corner of one of the stages (the Babylonians always buried records beneath the corners of their public edifices), informs us that this temple was a restoration by Nebuchadnezzar of a very ancient one, which in his day had become, from "extreme old age," a heap of rubbish. This edifice in its decay has left one of the grandest and most impressive ruins in all the East. The Babylonian palaces and palace-mounds, in all essential features, were like those of the Assyrians, already described. The so-called Hanging Gardens excited the greatest admiration of the ancient Greek visitors to Babylon. They were constructed by Nebuchadnezzar, to please his wife Amytis, who, tired of the monotony of the Babylonian plains, longed for the mountain scenery of her native Media. The gardens were probably built somewhat in the form of the tower- temples, the successive stages being covered with earth, and beautified with rare plants and trees, so as to simulate the appearance of a mountain rising in cultivated terraces towards the sky.
