The ancient Egyptians, whose religion of boundless antiquity is pre-eminent in the old world for its passionate earnestness, its purity, and lofty idealism certainly held that some diseases were due to the action of evil spirits or demons, who in exceptional circumstances had the power of entering human bodies and of vexing them in proportion to the opportunities consciously or unconsciously given to their malign natures and influences. Moreover, the Egyptians were regarded as being supremely gifted in the art of curing the diseases caused by demoniacal possession, and one noteworthy instance of this was inscribed upon a stele and set up in the temple of the god Khonsu at Thebes so that all men might learn his might and his glory.[1] When King Rameses II was in Mesopotamia the various princes made him many offerings of gold and gems, and amongst other came the Prince of Bekhten, who brought his daughter, the fairest maiden of that land. When the king saw he loved her and bestowed upon her the title of “Royal spouse, chief lady, Rā-neferu” (the beauties of Ra, the Sun-god), and taking her back to Egypt he married her with great pomp and hallowed solemnity. In the fifteenth year of the king’s reign there arrived at his court an ambassador from the Prince of Bekhten, bearing rich presents and beseeching him “on behalf of the lady Bent-ent-resht, the younger sister of the royal spouse Rā-neferu, for, behold, an evil disease hath laid hold upon her body,” “wherefore,” said the envoy, “I beseech thy Majesty to send a physician[2] to see her.” Rameses ordered the books of the “double house of life” to be brought and the wise men to choose from their number one who might be sent to Bekhten. They selected the sage Tehuti-em-heb, who in company with the ambassador forthwith departed on their journey, and when they had arrived the Egyptian priest soon found the lady Bent-ent-resht was possessed of a demon or spirit over which he was powerless. Wellnigh in despair the Prince of Bekhten sent again to the king begging him to dispatch even a god to his help.
