An ancient Arab temple, a small square structure in the grand mosque of Mecca, with a mysterious black stone, probably an aerolite, built in it, on which all pilgrims who visit the shrine imprint a kiss; "the Keblah of all Moslem, the eyes of innumerable praying men being turned towards it from all the quarters of the compass five times a day."
