For centuries before Mohammed’s time the Kaaba at Mecca had been a famous sanctuary and a religious centre for the nomadic Arabs. It is stated that there were 360 idols in the temple, a number which suggests a connection with the year of 360 days in use among the Arabs. The most celebrated of these idols bore the name of Hobal, and was the figure of a man cut out of red agate. There was a tradition to the effect that this idol had been brought from Belka in Syria. As one of the hands was broken off, the Koreish, the Arab tribe having charge of the Kaaba, repaired this defect by attaching a golden hand, in which were held seven arrows, plain shafts without heads or feathers, similar to the arrows used for divination by the Arabs. For some occult reason the agate was supposed to exercise a certain control over meteorological phenomena, for in Persia it was believed to ward off tempests, while prayers for rain in time of drought were made to this agate image of the Kaaba.[158] [Illustration: _LE TEMPLE DE LA MECQUE_ THE KAABA AT MECCA The letter A indicates the place where the Black Stone is inserted in the wall of the building. From “Histoire générale des cérémonies religieuses de tous les peuples du monde,” by Abbé Banier and Abbé Mascrier, Paris, 1741. ] Much has been written regarding the Black Stone, but perhaps the most satisfactory description is that given by Burckhardt, who writes:[159] At the Northeast corner of the Kaabah, near the door, is the famous “Black Stone”; it forms part of the sharp angle of the building at from four to five feet above the ground. It is an irregular oval, about seven inches in diameter, with an undulated surface, composed of about a dozen smaller stones of different sizes and shapes, well joined together with a small quantity of cement, and perfectly smooth; it looks as if the whole had been broken into many pieces by a violent blow, and then united again. It is very difficult to determine accurately the quality of this stone, which has been worn to its present surface by the millions of touches and kisses it has received. It appears to me like lava, containing several small extraneous particles of a whitish and of a yellowish substance. Its color is now a deep reddish-brown, approaching to black.
