Pliny even says that the Egyptians examined the bodies after death, to ascertain the nature of the diseases of which they had died; and we can readily believe that a people so far advanced in civilization and the principles of medicine as to assign to each physician his peculiar branch, would have resorted to this effectual method of acquiring knowledge and experience.
It is evident that the medical science of the Egyptians was sought and appreciated even in foreign countries; and we learn from Herodotus, that Cyrus and Darius both sent to Egypt for medical men. In later times, too, they continued to be celebrated for their skill; Ammianus says it was enough for a doctor to say he had studied in Egypt to recommend him; and Pliny mentions medical men going from Egypt to Rome. But though their physicians are often noticed by ancient writers, the only indication of medical attendance appears to be in the paintings of Beni Hassan; and even there it is uncertain whether a doctor, or a barber, be represented.
Their doctors probably felt the pulse; as Plutarch shows they did at Rome, from this saying of Tiberius, "a man after he has passed his thirtieth year, who puts forth his hand to a physician, is ridiculous;" whence our proverb of "a fool or a physician after forty."
Diodorus tells us, that dreams were regarded in Egypt with religious reverence, and the prayers of the devout were often rewarded by the gods, with an indication of the remedy their sufferings required; and magic, charms, and various supernatural agencies, were often resorted to by the credulous; who "sought to the idols, and to the charmers, and to them that had familiar spirits, and to the wizards."
Origen also says, that when any part of the body was afflicted with disease, they invoked the demon to whom it was supposed to belong, in order to obtain a cure.
In cases of great moment oracles were consulted; and a Greek papyrus found in Egypt mentions divination "through a boy with a lamp, a bowl, and a pit;" which resembles the pretended power of the modern magicians of Egypt. The same also notices the mode of discovering theft, and obtaining any wish; and though it is supposed to be of the 2d century, the practices it alludes to are doubtless from an old Egyptian source; and other similar papyri contain recipes for obtaining good fortune and various benefits, or for causing misfortunes to an enemy.
Some suppose the Egyptians had even recourse to animal magnetism, and that dreams indicating cures were the result of this influence; and (though the subjects erroneously supposed to represent it apply to a very different act) it is not impossible that they may have discovered the mode of exercising this art, and that it may have been connected with the strange scenes recorded at the initiation into the mysteries. If really known, such a power would scarcely have been neglected; and it would have been easy to obtain thereby an ascendency over the minds of a superstitious people.
Indeed, the readiness of man at all times to astonish on the one hand, and to court the marvelous on the other, is abundantly proved by present and past experience. That the nervous system may be worked upon by it to such a degree that a state either of extreme irritability, or of sleep and coma, may be induced, in the latter case paralyzing the senses so as to become deadened to pain, is certain; and a highly sensitive temperament may exhibit phenomena beyond the reach of explanation; but it requires very little experience to know that we are wonderfully affected by far more ordinary causes; for the nerves may be acted upon to such an extent by having as we commonly term it "our teeth set on edge," that the mere filing a saw would suffice to drive any one mad, if unable to escape from its unceasing discord. What is this but an effect upon the nerves? and what more could be desired to prove the power of any agency? And the world would owe a debt of gratitude to the professors of animal magnetism, if, instead of making it, as some do, a mere exhibition to display a power, and astonish the beholders, they would continue the efforts already begun, for discovering all the beneficial uses to which it is capable of being applied.
We might then rejoice that, as astrology led to the more useful knowledge of astronomy, this influence enabled us to comprehend our nervous system, on which so many conditions of health depend, and with which we are so imperfectly acquainted.
The cure of diseases was also attributed by the Egyptians to Exvotos offered in the temples. They consisted of various kinds. Some persons promised a certain sum for the maintenance of the sacred animals; or whatever might propitiate the deity; and after the cure had been effected, they frequently suspended a model of the restored part in the temple; and ears, eyes, distorted arms, and other members, were dedicated as memorials of their gratitude and superstition.
