Stones of Healing: Martius

The so-called "doctrine of signatures" treated of the marks set by nature upon certain objects to denote their usefulness in the cure of diseases affecting different parts of the body, or their power to neutralize the effects of the bites of certain animals or reptiles. Of this theory Martius says that the "signatures" are not to be sought in a fanciful resemblance to the form of the objects with the diseased parts of the human body, but rather in the color, odor, taste, composition, etc., of the objects. (Martius, "Unterricht von der Magiae Naturali, Leipzig, 1717, p. 290.) Medieval medical literature has no more interesting example than the treatise entitled "Thesaurus Pauperum," or the "Poor-man's Treasury," written by Petrus Hispanus, who later reigned for a brief period as pope under the name of John XXI (1276-1277). The birthplace of the author was Lisbon in Portugal, and he studied for some time at the University of Paris, where his learning earned him high praise. Prior to his election as pope, he served for a time as first physician to Pope Gregory X (1271-1276). Most of the remedies prescribed in this little treatise are naturally such as had long been popular among the peasantry, and the ingredients of which could easily be secured; vegetable growths, plants, herbs and flowers, and certain parts of the more common animals, served here, as in Pliny's day and earlier still, as those most highly favored. Of the comparatively few mineral substances whose use is recommended may be noted the red variety of chelidonius or "swallow stone," for the cure of epilepsy; the powder of the "iris" (probably an iridescent variety of quartz) was also a cure for epileptics. Then we find, strange to say, a recommendation of such costly remedial agencies as emerald and sapphire, either of which if touched on the eye would heal diseases of that organ. Cold stones placed on the temples and tightly bound on were said to arrest bleeding from the nose, and coral was a great help in syncope. For stone in the bladder two mineral substances, "humus" and "songie," are warmly recommended (the former can scarcely be held to signify mere "soil"), as are also "stones found in the gizzards of cocks" (the alectorius) and those from the bladders of hogs. All these were to be reduced to powder, dissolved in liquid, and taken in the form of potions. The use of stones and coral rather as amulets or talismans than as remedies is occasionally mentioned. Thus the loadstone, if worn, is said to remove discord between man and woman; coral, if kept in the house, destroyed all evil influences, and if a woman wore touching her skin a concretion taken from the stomach of a she-goat that had not had young, this woman would never bear a child.

The curious old medical treatise in verse called the "Schola Salernitana," was translated into English by Sir James Harington in 1607. The following lines give advice that is as appropriate to the conditions of our own age as to those of any other:

Use three physitians still, first doctor Quiet, Next doctor Merry-man and doctor Dyet.

Whether with or without intention, the translator has omitted to render the qualification given in the original: "Si tibi deficiant medici" (if other doctors are lacking).

The terrible plague known as the Black Death is said to have claimed 13,000,000 victims in Europe in the years 1347 and 1348. A contemporary, Olivier de la Haye, in a poem describing this fearful visitation, gives a number of recipes used, or to be used as remedies. In one of these there appear as ingredients pearls, jargoons, emeralds and coral, one-sixth of a drachm of each of these materials entering into the composition of the prescription. The symptoms of this form of the plague, as described by the old writers, are said to resemble closely those of the disease that was prevalent not long ago in some parts of Asia, especially in northern China and Manchuria.
