To the idolatrous Arabs one of the most ancient universal objects of worship was that Black Stone, still kept in the building called Caabah, at Mecca. Diodorus Siculus mentions this Caabah in a way not to be mistaken, as the oldest, most honored temple in his time; that is, some half-century before our Era. Silvestre de Sacy says there is some likelihood that the Black Stone is an aerolite. In that case, some man might _see_ it fall out of Heaven! It stands now beside the Well Zemzem; the Caabah is built over both. A Well is in all places a beautiful affecting object, gushing out like life from the hard earth;--still more so in those hot dry countries, where it is the first condition of being. The Well Zemzem has its name from the bubbling sound of the waters, _zem-zem_; they think it is the Well which Hagar found with her little Ishmael in the wilderness: the aerolite and it have been sacred now, and had a Caabah over them, for thousands of years. A curious object, that Caabah! There it stands at this hour, in the black cloth-covering the Sultan sends it yearly; "twenty-seven cubits high;" with circuit, with double circuit of pillars, with festoon-rows of lamps and quaint ornaments: the lamps will be lighted again _this_ night,--to glitter again under the stars. An authentic fragment of the oldest Past. It is the _Keblah_ of all Moslem: from Delhi all onwards to Morocco, the eyes of innumerable praying men are turned towards it, five times, this day and all days: one of the notablest centres in the Habitation of Men.
