Of the jasper, De Boot relates,[[289]] from his own experience, that for checking hemorrhages the red variety is the most effective, and, in this connection, he describes the case of a young woman in Prague, who had suffered for six years from hemorrhages. Many different remedies had been tried without avail, and when De Boot was called in to attend the case, he advised the woman to wear a red jasper. As soon as this stone was attached to her person the hemorrhage ceased. After wearing the jasper for some time, the woman thought she could safely lay it aside, but whenever she did so the hemorrhage returned after a longer or shorter interval, while it always ceased immediately she resumed wearing the stone. This seemed to prove conclusively that it checked the flow of blood. Eventually the woman was so effectively cured that she was able to give up wearing the stone. Green jasper, if worn attached to the neck so as to touch the gastric region, was, according to De Boot, a cure for all diseases of the stomach. The same writer alludes to the belief that the virtue of this stone was enhanced if it were engraved with the image of a scorpion while the sun was entering the constellation Scorpio, but he rejects this belief as entirely superstitious and futile, while admitting that, to obtain the best results, the jasper should always be set in silver.
Pear-shaped pieces of red jasper seem to have been more especially favored for use as amulets. Italian amulets of to-day show this, and Bellucci finds that the form is chosen as representing a drop of blood, and thus aiding, by sympathetic magic, in the cure of hemorrhages or wounds, and preventing the infliction of the latter. Sometimes such amulets of red jasper are attached to the bed-post by a red ribbon. In the case of a particularly valued amulet of this type, Bellucci was informed by the peasant owner that it owed its great virtue to having been blessed by the parish priest. Thus the traditional power of a pagan amulet received the sanction of the church and the object was associated with purely Christian amulets.[[290]]
Jet
Jet, the gagates of the ancients, was said to have been first found in the river Gagates in Lycia, whence its name was derived. Galen, the greatest physician of ancient times, reports, however, that he searched in vain for this river, although he sailed in a small vessel along the whole coast of Lycia, so that he might closely observe it. Still, he did not give up his search for the material, even when he failed to find its reputed source, and in Cælo-Syria, on a hill on the eastern shore of the Dead Sea, he came across certain black, crustaceous stones, which emitted a slender flame when placed in the fire. These must have been small masses of bitumen, and, according to Galen, they were used for chronic swellings of the knee-joint “which are difficult to cure.”[[291]]
The fumes of jet are mentioned as a remedy for the pest in one of the earliest Greek medical treatises, written by Nicander, who flourished in the second century B.C. He declares that the most virulent pestilence could be driven away if the bedrooms were fumigated with the smoke of the slow-burning jet.[[292]] The plague was called the black plague and naturally the aid of a black substance was sought to cure it.
For Pliny, jet was endowed with many medicinal virtues. Its fumes were a cure for hysteria and were said to reveal the presence of a latent tendency to epilepsy; connected with this in some way was the curious belief, repeated by later authors with certain variations, that these fumes could also be used as a test of virginity. When powdered and mixed with wine, jet relieved the pains of those suffering from toothache, and if the powder were combined with wax, a salve was produced that gave very beneficial results in cases of scrofula.[[293]] Even as a toilet preparation jet was recommended for use, and a most excellent dentifrice is said to have been made from it. In this connection jet was credited with tonic as well as cleansing properties, as is shown by the words of Bartholomæus Anglicus, who declares that this material was especially beneficial for “feeble teeth and waggyng,” since it strengthened them and made them firm.[[294]]
The delusions and hallucinations of melancholic subjects were believed to be put to flight by the power of jet, either in its solid form or when reduced to a solution. The fact that this material was often used for the beads of rosaries was thought to have some connection with its supposed virtues, since the bad dreams or dreadful hallucinations sometimes accompanying melancholia were designated as “demons,” and thus the prayers counted off on jet beads might be supposed to have the greater power to banish the devil and his black angels. The old writer who cites these particulars about jet, adds that there was to be found in the river Nile a black stone the size of a bean, at sight of which dogs would stop barking, and which also drove away evil spirits. Here we have another among many instances of the curious blending of the doctrines of sympathy and antipathy, the black stone repelling the imps of darkness and nullifying the spells of the Black Art.[[295]]
Lapis Armenus
The lapis Armenus was well known to the Arabs under the name hajer Armeny, and their medical writers describe it quite accurately and distinguish it from the somewhat similar lapis lazuli, with which it was often confused in ancient times. Ibn Beithar states that if properly prepared it would not provoke nausea, as was otherwise the case. It was said to cause a very abundant evacuation of bile and must have been regarded as an efficient remedy for the bilious disorders so general in warm climates.[[296]]
A “blue amulet” against vertigo, melancholia and epilepsy could be made up of the following ingredients: shavings from an elk’s horn and from a human skull, to be reduced to a fine powder, the excrement of a peacock, white agate, lapis lazuli or lapis Armenus, of which enough was to be used to give the required sky-blue tint. The whole mass was then to be softened by the addition of gum tragacanth, and formed into heart-shaped tablets, which were to be dried out in the air, and then smoothed on a turning-lathe. These amulets were to be worn attached to the neck or the arm, sometimes they were enclosed in a little receptacle of silver or of red sandal-wood and suspended from the neck.[[297]]
