His personal experience.
We have already said that Alexander is no mere compiler but embodies the results of his own observation and experience during a long period of travel and medical practice. He frequently asserts that he has tested this or that for himself, or that the prescription in question has been “approved by long use and experience,”[2376] so that it is not surprising that we find the name Alexander still associated with medical “experiments” in manuscripts dating from the twelfth to fifteenth centuries.[2377] One of his cures for epilepsy he learned “from a rustic in Tuscany” (Thuscia?) but afterwards often employed with success himself.[2378] “It is a marvelous and exceptional medicine which you will communicate to no one,” concludes Alexander, a rather surprising prohibition in view of the fact that it was a popular remedy to begin with. Folk-lore, however, is often supposed to be kept secret. Another general rule which holds true in Alexander’s case is that these empirical remedies are apt to be the most superstitious, and conversely that marvels are apt to be supported by solemn assurance of their experimental testing.
Extent of his superstition.
Two centuries ago Milward wrote of Alexander of Tralles, “But there is another objection to our author’s character which I cannot pretend to say much in defence of, and that is, his being addicted to charms and amulets. It is very surprising that one who discovers so much judgment in other matters should show so much weakness in this.”[2379] Alexander certainly devotes more space to superstition relatively to the length of his book than Aëtius does and also is hospitable to a wider range of more or less magical notions and practices. One notices, however, in his book that the treatment of certain diseases, such as epilepsy, colic, gout, and quartan fever, is more likely to involve magical and astrological procedure than that of other ailments such as earache and disorder of the spleen. This is also apt to be the case with other ancient and medieval medical works. But it is doubtful if the distinction can be sharply drawn that magic was resorted to more in those diseases which seemed most mysterious and incurable.
Physica.
The chief circumstance which renders some parts of Alexander’s work more superstitious than others is that he sometimes, after concluding the usual medical description of the disease and prescriptions for it, adds a list of what he calls physical or natural medicines (φυσικά), which are for the most part ligatures and suspensions but involve also the employment of incantations and engraved images or characters. Apparently he calls these remedies physica, because they supposedly act by some peculiar property or occult virtue of the substance which is bound on or suspended and constitute a sort of natural magic. Alexander explains that “since some cannot observe a diet nor endure medicine, they compel us in the case of gout to employ physical remedies and ligatures; and in order that the well-trained physician may be instructed in every side of his art and able to help all sick persons in every way, I come to this subject.”[2380] This rather apologetic tone and the fact that he separates the physica from his other remedies show that he regards them as not quite on the same level with normal medical procedure. He goes on to say, however, that although there are many of these “physical” remedies which are efficacious, he will write down only those proved true by long use. In discussing fevers he again justifies the inclusion of physica in much the same way and says that those now mentioned were learned by him during a long-extended practice and experience.[2381] It is to be noted that some of these chapters on physical ligatures do not appear in the Latin version in three books, at least as it was printed in 1504.
Occult virtue of substances applied externally.
One ligature which is “quite celebrated and approved by many” and which instantly lessens the pain of ulcers in the feet, makes use of muscles from a wild ass, a wild boar, and a stork, binding the right muscles about the patient’s right foot and the left muscles about the left foot. Some persons, however, do not intertwine the muscles of the stork with the others but put them separately into the skin of a sea-calf. Also they take care to bind the other muscles about the patient’s feet when the moon is in the west or in a sterile sign and approaching Saturn. Others bind on the tendons and claws of a vulture, or the feet of a hare who should remain alive.[2382] Alexander seems to regard the carcass of the ass as especially remedial in the case of epilepsy. In Spain he learned to use the skull of an ass reduced to ashes and he recommends employing the forehead and brain of an ass as amulets.[2383] A suspension for quartan fever consists of a live beetle firmly fastened on the outside of a red linen cloth and hung about the neck. “This is true and often tested by experience,” Alexander assures us. Also excellent for this purpose are hairs from a goat’s cheek or a green lizard combined with clippings of the patient’s finger nails and toe nails. It is confirmed by the testimony of all “natural” physicians that the blood qui primus a virgine fuerit excretus is naturally hostile to quartan fever. Even if the girl is not chaste, the blood will be efficacious, if applied to the patient’s right hand or arm.[2384] Alexander knew a man who treated quartan fever by giving an undergarment of the patient to a woman in childbirth to wear, after which the patient wore it again and was cured “miraculously by some antipathy and occult influence.”[2385]
Other things used as ligatures and in amulets.
The materials employed in Alexander’s therapeutics are sometimes those which we associate especially with magic arts, such as the hair and nail-parings already mentioned. Against epilepsy he employs nails from a cross or wrecked ship, or the blood-stained shirt of a gladiator or criminal who has been slain. The nails are bound to the patient’s arm; the shirt is burned and the patient given the ashes in wine seven times. The use of a nail from a cross is a method ascribed to Asclepiades. Other materials recommended by Alexander against gout and epilepsy include the herb night-shade, the stones magnet and aetites, blood of a swallow and urine of a boy, chameleons in varied forms, and the stones found in dissected swallows of which we have heard before and shall hear yet again. For Alexander these stones are black and white, but he states that they are not found in all young swallows but are said to appear only in the first-born, so that one often has to dissect a great many birds before one finds any. In these passages on Physica Alexander cites such authors of magical reputation as Ostanes and Democritus, and tells how the latter suffered in youth from epilepsy until an oracle from Delphi instructed him to make use of the worms in goats’ brains. When a goat sneezes violently, some of these worms are expelled into his nostrils, whence they should be carefully extracted in a cloth without allowing them to touch the ground. Either one or three of them should then be worn about the epileptic’s neck wrapped in the thin skin of a black sheep.[2386]
