'The Sheîkh of the Saadîch-derwishes rides to the chief Sheîkh of all the derwishes of Egypt, El Bekri. On the way thither, a great number of these holy folk, and others, too, who fancy themselves not a whit behind-hand in piety, throw themselves flat on the ground, with their faces downward, and so that the feet of one lie close to the head of the next; over this living carpet the sheîkh rides on his horse, which is led on each side by an attendant, in order to compel the animal to the unnatural march. Each body receives two treads of the horse; most of them jump up again without hurt, but whoever suffers serious, or as it occasionally happens, mortal injury, has the additional ignominy to bear of not having pronounced, or not being able to pronounce, the proper prayers and magical charms that alone could save him.' 'What a fearful barbarous worship' (the Sikr, in which the derwishes dance until exhausted, howling 'No God but Allah') 'which the astounded multitude, great and small, gentle and simple, gaze upon seriously, and with stupid respect, and in which it not unfrequently takes a part! The invoked deity is manifestly much less an object of reverence than the fanatic saints who invoke him; for mad, idiotic, or other psychologically-diseased persons are very generally looked upon as holy by the Mohammedans, and treated with great respect. It is the demoniacal, incomprehensibly-acting, and therefore fearfully-observed, power of nature that the natural man always reveres when he perceives it, because he is sensible of some connection between it and his intellectual power, without being able to command it; first in the mighty elements, then in the wondrous but obscure law-governed instincts of animals, and at last in the yet more overpowering ecstatical or generally abnormal mental condition of his own race.' The right answer to the enigma of the Sphinx is Man. But this creature prostrating himself under the Sheîkh's horse, or under the invisible Sheîkh called Allah, and ascribing sanctity to the half-witted, is not Man at all. Those hard-worked slaves who escaped into the wilderness, and set up for worship an anthropomorphic Supreme Will, and sought their promised milk and honey in this world alone, carried with them the only force that could rightly answer the Sphinx. Their Allah or Elohim they heard say,--'Why howlest thou to me? Go forward.' Somewhat more significant than his usual jests was that cartoon of Punch which represented the Sphinx with relaxed face smiling recognition on the most eminent of contemporary Israelites returning to the land of his race's ancient bondage, to buy the Suez Canal. The Suez Canal half answers the Sphinx; when man has subdued the Great Desert to a sea, the solution will be complete, and the Sphinx may cast herself into it.
