Malachite
Many medicinal virtues were ascribed to malachite. Worn as an amulet, it averted attacks of faintness, prevented hernia, and saved the wearer from danger in falling. In this latter respect similar powers seem to have been admitted in the case of the green malachite as were attributed to the light blue or greenish-blue turquoise. If malachite were reduced to a powder, dissolved in milk and taken as a potion, it cured cardiac pains and colic; mixed with honey, and applied with a linen cloth to a wound, it stanched the flow of blood, and cramps were relieved if this solution were applied to the affected part; lastly, if mixed with wine, it was a cure for virulent ulcers.[[302]]
Powdered malachite was sometimes administered medicinally, with what results we have little definite information; certainly, if not very carefully used, the effect would have been anything but favorable. A friend of De Boot once told the latter that a dose of six grains of powdered malachite acted as a purgative, but the wary doctor confesses that he never ventured to test the efficacy of this prescription.[[303]] In Bavaria, at the present time, mothers and midwives are fond of wearing pieces of malachite set in rings or strung for use as necklaces. These are believed to help the dentition of children and are also thought to bring more clients to the midwives. Amulets of this and other kinds were sold in Bavaria, in the seventeenth century, by wandering students and by gypsies.[[304]]
Median Stone
Of the so-called Median stone we read, in Konrad von Megenberg’s “Buch der Natur,”[[305]] that it had powers of good and evil; “for when dissolved in the milk of a woman who has borne a son, it restores sight to the blind.” It also cured gout and insanity. If, however, anyone were so ill-advised as to dissolve the stone in water and partake of the solution, he would die of hasty consumption; or if he simply bathed his forehead with the liquid, he would be robbed of his sight.
Onyx
A famous medicinal stone was at one time in the Abbey of St. Alban, founded in 793 A.D. by Offa, King of Mercia, in honor of the British protomartyr. In 1010, under Abbot Geoffrey de Gorham, a sumptuous shrine was erected to receive St. Alban’s body; this shrine was principally of silver, and was richly adorned with precious stones, chosen from among those in the treasury of the monastery. The records state that one of these stones “was so large that a man could not grasp it in his hand.” It was believed to give great help to women in childbirth. Hence, it was not set in the shrine, but was left free, so that it might be taken from house to house as required. The size of this stone and the fact that it was not used for ornamentation might have induced the belief that it was one of the singular “eagle-stones,” so celebrated in ancient and medieval times, but it is expressly described as an onyx-gem, the gift of King Ethelred II (968–1016) to the monastery. From the description we learn that on one side of this onyx was cut an image of Esculapius, the god of healing, and on the other that of “a boy bearing a buckler.” As the art of gem-cutting was practically unknown in Europe in the tenth century, this must have been an antique gem, and may have served as a pagan amulet many centuries before it was placed upon the shrine of a Christian saint and used as a Christian amulet.[[306]]
An old manuscript of Matthew Paris[[307]] gives a sketch of the gem from this author’s own hand. As the special power exerted by this talisman was to aid women in their confinements, it was loaned out from time to time to such as were considered worthy of the honor. In one case, however, it came into untrustworthy hands, for the favored lady failed to return the gem when her immediate need of its help had passed, retaining it in her possession until her death, when she bequeathed it to her daughter. During her lifetime the latter appears to have had no prickings of conscience, but on her death-bed, possibly through the exhortations of her confessor, she made provision that the long-lost sardonyx should be returned to the Abbey. It is said to have borne the name Kaadman, which Mr. Thomas Wright regarded as a corruption of cadmeus or cameus, early forms of our “cameo.”[[308]]
Pyrite
In Geneva and in the neighboring regions great virtues are ascribed to a cut and facetted iron (pyrite), very hard, susceptible of a high polish and of resplendent lustre. This is cut to resemble the rose or brilliant form of diamond, and is set in rings, buckles, and other ornaments. In appearance it resembles polished steel and is called pierre de santé, or “health-stone,” for it is believed to grow pale when the health of the wearer is about to fail.[[309]] This substance is known as marcasite and is a bisulphide of iron. In the time of Louis XVI it was largely used for ornamental purposes; at present steel has almost entirely taken its place, although it is still utilized to a limited extent. Many believe that this is the material to which Victor Hugo alludes in his great romance, “Les Miserables,” as having been manufactured by Jean Valjean.
