Its magnitude was 480 furlongs, or sixty miles, in compass. It was built in an exact square of fifteen miles on each side, and was surrounded by a brick wall eighty-seven feet thick and 350 feet high, on which were 250 towers, or, according to some writers, 316. The top of the wall was wide enough to allow six chariots to drive abreast. The materials for building the wall were dug from a vast ditch or moat, which was also walled up with brickwork and then filled with water from the River Euphrates. This moat was just outside of the walls, and surrounded the city as another strong defence.
The city had 100 brass gates, one at the end of each of its fifty streets. The streets were 150 feet wide and ran at right angles through the city, thus forming 676 great squares. Herodotus says besides this there was yet another wall which ran around within, not much inferior to the other, yet narrower, and the city was divided into two equal parts by the River Euphrates, over which was a bridge, and at each end of the bridge was a palace. These palaces had communication with each other by a subterranean passage.
To prevent the city from suffering from an overflow of the river during the summer months, immense embankments were raised on either side, with canals to turn the flood waters of the Tigris. On the western side of the city an artificial lake was excavated forty miles square, or 160 miles in circumference, and dug out, according to Megasthenes, seventy-five feet deep, into which the river was turned when any repairs were to be made, or for a surplus of water, in case the river should be cut off from them.
Near to the old palace stood the Tower of Babel. This prodigious pile consisted of eight towers, each seventy-five feet high, rising one upon another, with an outside winding staircase to its summit, which, with its chapel on the top, reached a height of 660 feet. On this summit is where the chapel of Belus was erected, which contained probably the most expensive furniture of any in the world. One golden image forty feet high was valued at $17,500,000, and the whole of the sacred utensils were reckoned to be worth $200,000,000. There are still other wonderful things mentioned. One, the subterraneous banqueting rooms, which were made under the River Euphrates and were constructed entirely of brass; and then, as one of the seven wonders of the world, were the famous hanging gardens; they were 400 feet square and were raised 350 feet high, one terrace above the other, and were ascended by a staircase ten feet wide. The terraces were supported by large vaultings resting upon curb-shaped pillars and were hollow and filled with earth, to allow trees of the largest size to be planted, the whole being constructed of baked bricks and asphalt. The entire structure was strengthened and bound together by a wall twenty-two feet in thickness. The level of the terrace was covered with large stones, over which was a bed of rushes, then a thick layer of asphalt, next two courses of bricks likewise cemented with asphalt, and finally plates of lead to prevent leakage, the earth being heaped on the platform and terrace and large trees planted. The whole had the appearance from a distance of woods overhanging mountains.
The great work is affirmed to have been effected by Nebuchadnezzar to gratify his wife, Anytis, daughter of Astyages, who retained strong predilection for the hills and groves which abounded in her native Media.
Babylon flourished for nearly 200 years in this scale of grandeur, during which idolatry, pride, cruelty, and every abomination prevailed among all ranks of the people, when God, by His prophet, pronounced its utter ruin, which was accordingly accomplished, commencing with Cyrus taking the city, after a siege of two years, in the year 588 Before Christ, to emancipate the Jews, as foretold by the prophets. By successive overthrows this once "Glory of the Chaldees' Excellency," this "Lady of Kingdoms," has become a "desolation" without an inhabitant, and its temple a vast heap of rubbish.
The ancient Tower of Babel is now a mound of oblong form, the total circumference of which is 2,286 feet. At the eastern side it is cloven by a deep furrow and is not more than fifty or sixty feet high, but on the western side it rises in a conical figure to the elevation of 198 feet, and on its summit is a solid pile of brick thirty-seven feet in height and twenty-eight in breadth, diminishing in thickness to the top, which is broken and irregular and rent by large fissures extending through a third of its height; it is perforated with small holes.
The fire-burnt bricks of which it is built have inscriptions on them, and so excellent is the cement, which appears to be lime mortar, that it is nearly impossible to extract one whole. The other parts of the summit of this hill are occupied by immense fragments of brickwork of no determinate figure, tumbled together and converted into solid vitrified masses, as if they had undergone the action of the fiercest fire, or had been blown up by gunpowder, the layers of brick being perfectly discernible. These ruins surely proclaim the divinity of the Scriptures. Layard says the discoveries amongst the ruins of ancient Babylon were far less numerous and important than could have been anticipated. No sculptures or inscribed slabs, the paneling of the walls of palaces, appear to exist beneath them, as in those of Nineveh. Scarcely a detached figure in stone, or a solitary tablet, has been dug out of the vast heaps of rubbish. "Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground." (Isaiah xxi. 9.)
The complete absence of such remains is to be explained by the nature of the materials used in the erection of even the most costly edifices of Babylon. In the vicinity there were no quarries of alabaster, or of limestone, such as existed near Nineveh. The city was built in the midst of an alluvial country, far removed from the hills. The deposits of the mighty rivers which have gradually formed the Mesopotamian plains consist of a rich clay. Consequently stone for building purposes could only be obtained from a distance. The black basalt, a favorite material amongst the Babylonians for carving detached figures, and for architectural ornaments, as appears from fragments found amongst the ruins, came from the Kurdish Mountains, or from the north of Mesopotamia.
The Babylonians were content to avail themselves of the building materials which they found on the spot. With the tenacious mud of their alluvial plains, mixed with chopped straw, they made bricks, whilst bitumen and other substances collected from the immediate neighborhood furnished them with an excellent cement. A knowledge of the art of manufacturing glaze, and colors, enabled them to cover their bricks with a rich enamel, thereby rendering them equally ornamental for the exterior and interior of their edifices. The walls of their palaces and temples were also coated, as we learn from several passages in the Bible, with mortar and plaster, which, judging from their cement, must have been of very fine quality. The fingers of a man's hand wrote the words of condemnation of the Babylonian empire "upon the plaster of the king's palace." Upon those walls were painted historical and religious subjects, and various ornaments, and, according to Diodorus Siculus, the bricks were enameled with the figures of men and animals. Images of stone were no doubt introduced into the buildings. We learn from the Bible that figures of the gods in this material, as well as in metal, were kept in the Babylonian temples. But such sculptures were not common, otherwise more remains of them must have been discovered in the ruins. The great inscription of Nebuchadnezzar, engraved on a black stone, and divided into ten columns, in the museum formed by the East India Company, appears to contain some interesting details as to the mode of construction and architecture of the Babylonian palaces and temples.
