In an anniversary discourse delivered before the New York Academy of Medicine, November 7, 1855, Dr. John Watson remarked that the numbers and pretensions of the illegitimate sons of Esculapius were as great in ancient as in modern times. And they were quite as wont to receive the patronage of the upper classes. The Emperor Nero thus favored the shrewd Lydian practitioner, Thessalus, who maintained that all learning was without value.
And if we may believe the statements of Pliny and Galen, the Roman quacks equalled, if they did not exceed, in ignorance and arrogance, the vast horde of handicraftsmen, bone-setters, herniotomists, lithotomists, abortionists, and poison-venders, who overran Southern Europe throughout the Middle Ages.
The inhabitants of ancient Chaldea, in common with many primitive peoples of later times, cherished the belief that all diseases were caused by demons. Medicine was merely a branch of Magic, and the chief healing agents were exorcisms, incantations, and enchanted beverages. There were, properly speaking, no physicians. Sometimes, wrote François Lenormant, in "Chaldean Magic," disease was regarded as an effect of the wickedness of different demons, and sometimes it appears to have been considered as the work of a distinct malevolent being, who exercised his power upon man.
According to the old Shamanic belief, which was the primeval religion of all mankind, every physical ailment is caused by a little devil which enters the body and can be expelled therefrom only by means of magic.
Abundant traces of this doctrine, says Charles Godfrey Leland in "Gipsy Sorcery," appear in our highest civilization and religion among people who gravely attribute every evil to the Devil, instead of to the unavoidable antagonisms of nature. "If," continues this writer, "a pen drops from our fingers, or a penny rolls from our grasp, the former, of course, falls on our new white dress, while the latter, nine times out of ten, goes directly to the nearest grating, crack or rat-hole."
In the religion of the ancient Copts, the Devil was believed to have inherited from his ancestors all the power attributed by ignorance and superstition to certain superior beings. He it was who originated all diseases, and by a singular contradiction, he likewise cured them, either directly or through the agency of the magicians and quacks who followed in his train.[206:1]
According to a widespread doctrine of antiquity, innumerable demons were ever active in endeavoring to inflict diseases upon the bodies of human beings.
No medical practitioner, however skilful, could successfully cope with these supernatural beings. Their evil designs could be checked only by experts in occult science. It has been said that whoever humors the credulity of man, is sure to prosper. The modern quack exemplifies this. "The Devil, the Christian successor of the ancient evil spirit, has exerted a great influence on the medical views of all classes of people. He and his successors were considered 'the disturbers of the peace' in the health of humanity. The Devil was able to influence each individual organ in a manner most disagreeable to the owner of the same."[206:2] Although the hideous portrayals of the Evil One, with horns, hoofs, pitchfork, and tail, appealed strongly to the imagination, they were wholly fanciful. If Satan were to appear in human form, as for example in the guise of a charlatan (says William Ramsey in "The Depths of Satan," 1889), we might expect him to assume the appearance, dress and demeanor of a gentleman.
Indeed, although the idea of the embodiment of evil is naturally repellent, a study of the Devil's personality, as represented in theology, romance, and popular tradition, reveals much that is interesting. In the rôle of a medical pretender, however, he deserves no more sympathy than any other quack.
In England, says William George Black, in "Folk-Medicine," the Devil has long represented much of the paganism still existing, and seems to have been regarded almost as the head of the medical profession. He has enjoyed the reputation of being able to inflict and cure diseases, not only those of his own production, but also natural diseases, since he knows their origin and causes better than physicians can. For, wrote the learned Dutch practitioner and demonologist, Johann Wier (1515-1588), physicians being younger than the Devil, must necessarily have had less experience.
