A more accurate image of this strange geometrical plan can be formed by supposing that one is viewing some eccentric oriental alphabet, as intricate as a thicket, against a background of shadows, and the misshapen letters should be welded one to another in apparent confusion, and as at haphazard, now by their angles, again by their extremities.

Sinks and sewers played a great part in the Middle Ages, in the Lower Empire and in the Orient of old. The masses regarded these beds of decomposition, these monstrous cradles of death, with a fear that was almost religious. The vermin ditch of Benares is no less conducive to giddiness than the lions’ ditch of Babylon. Teglath-Phalasar, according to the rabbinical books, swore by the sink of Nineveh. It was from the sewer of Münster that John of Leyden produced his false moon, and it was from the cesspool of Kekscheb that oriental menalchme, Mokanna, the veiled prophet of Khorassan, caused his false sun to emerge.
