“ The Kubbet-es-Sakhra, or Dome of the Rock, at Jerusalem, is only a shrine erected over the sacred rock, so that the title often ascribed to it as “the mosque of Omar” is misleading. The mosque of the Omayyads in Damascus was built by the Caliph Walid in A.D. 705 on the foundations of the basilican church of St John: its plan differs therefore from the normal type in that its arcades run east and west, and the transept in the centre becomes the prayer chamber. ”
