Nine hundred and fifty yards from the side of the river, and about a mile to the north of what is called the palace, stands the most remarkable ruin of the eastern division. This is called Mukallibè, a word signifying "overturned." This was visited, in 1616, by Della Valle, who determined it to be the tower of Belus; and this opinion has been adopted, erroneously, by Rennell and other writers. It is of an oblong shape, irregular in its height and the measurement of its sides, which face the cardinal points; the northern side being two hundred yards in length; the southern side, two hundred and nineteen; the eastern, one hundred and eighty-two; and the western, one hundred and thirty-six. The elevation of the highest angle, one hundred and forty-one feet. This mound is a solid mass. Near its summit appears a low wall, with interruptions, built of unburnt bricks, laid in clay mortar of great thickness, having a layer of reeds between every layer of bricks. On the north side are vestiges of a similar wall. The south-west angle, which is the highest point, terminates in a turret; or, rather, heaps of rubbish, in digging into which, layers of broken burnt brick, cemented with mortar, are discovered, and whole bricks, with inscriptions on them, are here and there found. The whole is covered with innumerable fragments of brick, pottery, pebbles, bitumen, vitrified scoria, and even shells, bits of glass, and mother-of-pearl! When Mr. Rich saw all these, he inquired of the Turk, that acted as guide, how he imagined the glass and mother-of-pearl came there?--"They were brought here by the deluge," answered the Turk. In describing this mound, Major Keppell says, that he found it full of large holes. "We entered one of them, and found them strewed with the carcases and skeletons of animals recently killed. The ordure of wild beasts was so strong, that prudence got the better of curiosity; for we had no doubt as to the savage nature of the inhabitants. Our guides, indeed, told us, that all the ruins abounded in lions and other wild beasts." Mr. Rich found, also, quantities of porcupine quills; and most of the cavities, he says, are peopled with bats and owls. The pile on the Mujelibé is called Haroot and Maroot, by the Arabs; and they believe that, near the foot of the pyramid, there still exists, though invisible to mankind, a well, in which those two wicked angels were condemned by the Almighty to be suspended by the heels until the end of the world, as a punishment for their vanity and presumption.[130]
