Among the Lushai-Kuki of Assam, Pathian the creator, a quasi-supreme and benevolent being, was acquainted with, but is not definitely stated to have been the author of, witchcraft. It was taught by his daughter, as a ransom for her life, to Vahrika, who had caught her stealing water from his private supply. Vahrika is described as “something like” Pathian--a purely mythological figure. He in turn taught it all to others.[140.3] In Japan, Jimmu {141} Tennō, the deified legendary founder of the empire, is said to have first taught the use of magical formulæ; while the gods Ohonamochi and Sukunabikona are credited with the invention of medicine and magic.[141.1] The ancient Egyptians held Thoth, the god of writing and guardian of law, “to have written the most sacred books and formulas with his own hand, and therein to have set down his knowledge of magic, in which art Isis was his only rival. His pre-eminence in magic naturally led to his becoming the god of medicine, for magic was fully as important to the medical practitioners of the Nile Valley as knowledge of remedies.”[141.2] In other words, medicine was not yet separated from magic, the physician was a sorcerer, who may have been versed in simples, but whose practice was essentially mysterious and derived its effect rather from what we call supernatural than natural modes of action. Hence to recognize Thoth as god of medicine was equivalent to recognizing him as god of magic, a character peculiarly suitable to a god of letters.
