In the Kaaba, the most ancient and remarkable building of the great Mosque at Mecca, is preserved a miraculous stone with the print of Abraham's feet impressed upon it. It is said, by Mohammedan tradition, to be the identical stone which served the patriarch as a scaffold when he helped Ishmael to rebuild the Kaaba, which had been originally constructed by Seth, and was afterwards destroyed by the Deluge. While Abraham stood upon this stone, it rose and sank with him as he built the walls of the sacred edifice. The relic is said to be a fragment of the same gray Mecca stone of which the whole building is constructed,--in this respect differing from the famous black stone brought to Abraham and Ishmael by the angel Gabriel, and built into the north-east corner of the exterior wall of the Kaaba, which is said by scientific men to be either a meteorite or fragment of volcanic basalt. It is popularly supposed to have been originally a jacinth of dazzling whiteness, but to have been made black as ink by the touch of sinful man, and that it can only recover its original purity and brilliancy at the day of judgment. The millions of kisses and touches impressed by the faithful have worn the surface considerably; but in addition to this, traces of cup-shaped hollows have been observed on it. There can be no doubt that both these relics associated with Abraham are of high antiquity, and may have belonged to the prehistoric worship which marked Mecca as a sacred site, long before the followers of the Prophet had set up their shrine there. In the sacred Mosque of Hebron, built over the cave of Machpelah, is pointed out a footprint of the ordinary size on a slab of stone, variously called that of Adam or of Mohammed. It is said to have been brought from Mecca some six hundred years ago, and is enclosed in a recess at the back of the shrine of Abraham, where it is placed on a sort of shelf about three feet above the floor. On the margin of the tank, in the court of the ruined mosque at Baalbec, there are shown four giant footmarks, which are supposed to have been impressed by some patriarch or prophet, but are more likely to have been connected with the ancient religion of Canaan, which lingered here to the latest days of Roman paganism. In the great Druse shrine of Neby Schaib near Hattin there is a square block of limestone in the centre of which is a piece of alabaster containing the imprint of a human foot of natural size, with the toes very clearly defined. The Druses reverently kiss this impression, asserting that the rock exudes moisture, and that it is never dry. There is a split in the rock across the centre of the footprint, which they account for by saying that when the prophet stepped here he split the rock with his tread. In Damascus there was at one time a sacred building called the Mosque of the Holy Foot, in which there was a stone having upon it the print of the feet of Moses.
