Omar Khayyam
(See Assassins.) Onimancy, or the observation of the angel Uriel, is thus performed. Upon the nails of the right hand of an unpolluted boy or a young virgin, or the palm of the hand, is put some oil of olives, or what is better, oil of walnuts mingled with tallow or blacking. If money or things hidden in the earth be sought, the face of the child must be turned towards the east. If crime be inquired into, or the knowledge of a person out of affection, towards the south; for robbery towards the west, and for murder towards the south. Then the child must repeat the seventy-two verses of the Psalms, which the Hebrew kabalists collected for the Urim and Thummim. These will be found in the third book of Reuclin on the kabalistical art, and in a treatise de verbo mirifico. In each of these verses occurs the venerable name of four letters, and the three lettered name of the seventy-two angels, which are referred to the inquisitive name Schemhammaphoras, which was hidden in the folds of the lining of the tippet of the high priest. When the curious student has done thus much, Saunders assures him that he "shall see wonders," but he omits to specify what these wonders are. Chiromancers give the name Onyomancy to the inspection of the natural signs on the nails.
