It may be conjectured that in their general plan the Babylonian palaces and temples resembled those of Assyria. We know that the arts, the religion, the customs, and the laws of the two kindred people were nearly identical. They spoke, also, the same language, and used, very nearly, the same written characters. One appears to have borrowed from the other; and, without attempting to decide the question of priority of independent existence as a nation and of civilisation, it can be admitted that they had to a certain extent a common origin, and that they maintained for many centuries an intimate connection. We find no remains of columns at Babylon, as none have been found at Nineveh. If such architectural ornaments were used, they must have been either of wood or of brick. The massy pillars, with Egyptian-like capitals, usually chosen by artists for the restoration of Belshazzar's palaces and temples, are the mere creations of fancy, and are not warranted by any existing remains whatever. The Babylonian column more probably resembled, in form and proportions, that of Nineveh and Persepolis. It may have been a modification of the Assyrian which afterwards gave birth to the Persian, for it was through Babylon that the arts appear to have penetrated partly, if not entirely, into Persia. Although the building materials thus used in the great edifices of Babylon may seem extremely mean when compared with those employed in the stupendous palace temples of Egypt, and even in the less massive edifices of Assyria, yet the Babylonians appear to have raised, with them alone, structures which excited the wonder and admiration of the most famous travellers of antiquity. The profuse use of color, and the taste displayed in its combination, and in the ornamental designs, together with the solidity and vastness of the immense substructure upon which the buildings proudly stood, may have chiefly contributed to produce this effect upon the minds of strangers. The palaces and temples, like those of Nineveh, were erected upon lofty platforms of brickwork. The origin of Assyrian architecture, which I have elsewhere described,[216] was especially that of Babylon. The bricks, as in Assyria, were either simply baked in the sun, or were burnt in the kiln. The latter are of more than one shape and quality. Some are square; others are oblong.[217] Those from the Birs Nimroud are generally of a dark red color, whilst those from the Mujelibé are mostly of a light yellow. Specimens have been frequently brought to this country, and are to be found in many public and private collections. The Babylonian inscribed bricks long excited the curiosity of the learned, and gave rise to a variety of ingenious speculations as to their use and meaning. By some they were believed to be public documents; others saw in the writing dedications to the gods, or registers of gifts to temples. The question has now been entirely set at rest by the discovery made by Dr.
