Superstition has ordained that certain stones should cure certain evils: the blood-stone was of very general efficacy, it was claimed, and the opal, when folded in a bay leaf, had the power of rendering the owner invisible. Some stones, especially the turquoise, turned pale or became deeper in hue according to the state of the owner's health; the owner of a diamond was invincible; the possession of an agate made a man amiable, and eloquent. Whoever wore an amethyst was proof against intoxication, while a jacynth superinduced sleep in cases of insomnia. Bed linen was often embroidered, and set with bits of jacynth, and there is even a record of diamonds having been used in the decoration of sheets! Another entertaining instance of credulity was the use of "cramp rings." These were rings blessed by the queen, and supposed to cure all manner of cramps, just as the king's touch was supposed to cure scrofula. When a queen died, the demand for these rings became a panic: no more could be produced, until a new queen was crowned. After the beheading of Anne Boleyn, Husee writes to his patroness: "Your ladyship shall receive of this bearer nine cramp rings of silver. John Williams says he never had so few of gold as this year!"
A stone engraved with the figure of a hare was believed to be valuable in exorcising the devil. That of a dog preserved the owner from "dropsy or pestilence;" a versatile ring indeed! An old French book speaks of an engraved stone with the image of Pegasus being particularly healthful for warriors; it was said to give them "boldness and swiftness in flight." These two virtues sound a trifle incompatible!
The turquoise was supposed to be especially sympathetic. According to Dr. Donne:
"A compassionate turquoise, that cloth tell
By looking pale, the owner is not well,"
must have been a very sensitive stone.
There was a physician in the fourth century who was famous for his cures of colic and biliousness by means of an iron ring engraved with an exorcism requesting the bile to go and take possession of a bird! There was also a superstition that fits could be cured by a ring made of "sacrament money." The sufferer was obliged to stand at the church door, begging a penny from every unmarried man who passed in or out; this was given to a silversmith, who exchanged it at the cathedral for "sacrament money," out of which he made a ring. If this ring was worn by the afflicted person, the seizures were said to cease.
The superstition concerning the jewel in the toad's head was a strangely persistent one: it is difficult to imagine what real foundation there could ever have been for the idea. An old writer gives directions for getting this stone, which the toad in his life time seems to have guarded most carefully. "A rare good way to get the stone out of a toad," he says, "is to put a... toad... into an earthen pot: put the same into an ant's hillocke, and cover the same with earth, which toad... the ants will eat, so that the bones... and stone will be left in the pot." Boethius once stayed up all night watching a toad in the hope that it might relinquish its treasure; but he complained that nothing resulted "to gratify the great pangs of his whole night's restlessness."
An old Irish legend says that "the stone Adamant in the land of India grows no colder in any wind or snow or ice; there is no heat in it under burning sods" (this is such an Hibernian touch! The peat fuel was the Celtic idea of a heating system), "nothing is broken from it by striking of axes and hammers; there is one thing only breaks that stone, the blood of the Lamb at the Mass; and every king that has taken that stone in his right hand before going into battle, has always gained the victory." There is also a superstition regarding the stone Hibien, which is said to flame like a fiery candle in the darkness, "it spills out poison before it in a vessel; every snake that comes near to it or crosses it dies on the moment." Another stone revered in Irish legend is the Stone of Istien, which is found "in the brains of dragons after their deaths," and a still more capable jewel seems to be the Stone of Fanes, within which it is claimed that the sun, moon, and twelve stars are to be seen. "In the hearts of the dragons it is always found that make their journey under the sea. No one having it in his hand can tell any lie until he has put it from him; no race or army could bring it into a house where there is one that has made way with his father. At the hour of matins it gives out sweet music that there is not the like of under heaven."
Bartholomew, the mediæval scientist, tells narratives of the magical action of the sapphire. "The sapphire is a precious stone," he says, "and is blue in colour, most like to heaven in fair weather and clear, and is best among precious stones, and most apt and able to fingers of kings. And if thou put an addercop in a box, and hold a very sapphire of India at the mouth of the box any while, by virtue thereof the addercop is overcome and dieth, as it were suddenly. And this same I have seen proved oft in many and divers places." Possibly the fact that the addercop is so infrequent an invader of our modern life accounts for the fact that we are left inert upon reading so surprising a statement; or possibly our incredulity dominates our awe.
The art of the lapidary, or science of glyptics, is a most interesting study, and it would be a mistake not to consider it for a few moments on its technical side. It is very ancient as an art. In Ecclesiasticus the wise Son of Sirach alludes to craftsmen "that cut and grave seals, and are diligent to make great variety, and give themselves to counterfeit imagery, and watch to finish a work."
