"A perfect medicine for bodies that be sick Of all infirmities to be relieved; This heleth nature and prolongeth lyfe eke." Probably no one would claim that the phenomena now grouped under the head of hypnotism were unknown before the end of the sixteenth century. They are as old as man, yes, probably older, since we know that some of the same phenomena apply to animals. But the claim might well be made that while isolated facts of this kind were well known, especially in the East, no scientific collaboration and explanation were attempted until this time. As with all other departments of science, we may trace a gradual development. Astrology of old taught the influence of the stars upon men, which doctrine was accepted by the great physician Theophrastus Paracelsus (1490-1541). This, however, was only part of his belief: the human body was endowed with a double magnetism; one portion attracted to itself the planets and was nourished by them, the result of which was the mental powers; the other portion attracted and disintegrated the elements, from which process resulted the body. He also claimed that the magnetic virtue of healthy persons attracted the enfeebled magnetism of the sick. With this theory of animal magnetism, it was only natural that he should value the use of the magnet very highly in the cure of diseases. This dual theory of magnetic cures, that of the magnetic influence of men on men and of the magnet on man, was prevalent for over a century, and found its latest exponent in Mesmer. Following Paracelsus, Glocenius, Burgrave, Helinotius, Robert Fludd, and Kircher believed that the magnet represented the universal principle by which all natural phenomena might be explained. This principle, existing as it did in the human body, was an important factor in health and disease. The great chemist Von Helmont (1577-1644) taught more precisely that a power resided in man by which he could magnetically affect others, and thereby cure the sick who were most influenced by it. He published a work on the effects of magnetism on the human frame.
