The Virtues of Precious Stones

The following passage from the "Faithful Lapidary" of Thomas Nicols, (Nicols, "Faithful Lapidary," London, 1659.) who wrote in the middle of the seventeenth century, illustrates the prevailing opinion in England at that time as to the virtues of precious stones:

"Perfectionem effectus contineri in causa. But it cannot truly be so spoken of gemms and pretious stones, the effects of which, by Lapidists are said to be, the making of men rich and eloquent, to preserve men from thunder and lightning, from plagues and diseases, to move dreams, to procure sleep, to foretell things to come, to make men wise, to strengthen memory, to procure honours, to hinder fascinations and witchcrafts, to hinder slothfulness, to put courage into men, to keep men chaste, to increase friendship, to hinder difference and dissention, and to make men invisible, as is feigned by the Poet concerning Gyges ring, and affirmed by Albertus and others concerning the ophthalmius lapis, and many other strange things are affirmed of them and ascribed to them, which are contrary to the nature of gemms, and which they as they are materiall, mixt, inanimate bodies neither know nor can effect, by the properties and faculties of their own constitutions: because they being naturall causes, can produce none other but naturall effects, such as are all the ordinary effects of gemms: that is, such effects as flow from their elementary matter, from their temper, form and essence; such as are the operations of hot and cold, and of all the first qualities, and all such accidents as do arise from the commixtion of the first qualities: such as are hardnesse, heavinesse, thicknesse, colour, and tast. These all are the naturall faculties of gemms, and these are the known effects of the union of their matter, and of the operation of the first qualities one upon another."

The long-continued concentration of vision on an object tends to produce a partial paralysis of certain functions of the brain. This effect may be noted in the helplessness of a bird when its gaze is fixed upon the glittering eyes of a serpent, or in the unwilling obedience yielded by a lion or some other wild animal when forced to look into the intent eyes of its trainer. In the same way those who gaze for a long time and without interruption on a crystal or glass ball, on an opal, a moonstone, a sapphire, or a cat's-eye, may become partially hypnotized or even fall into a profound sleep. The condition induced, whether it be that of semi-trance, of hypnotism, or simply due to the imaginative workings of the brain, is believed to give an insight into the future. This hypnotic effect is probably caused by some gleam or point of light in the stone, attracting and fixing the beholder's gaze. The moonstone, the star sapphire, and the cat's-eye are all gems which possess a moving light, a moving line, or three crossed lines, and they are believed by the Orientals to be gems of good luck. Indeed, it is supposed in the East that a living spirit dwells within these stones, a spirit potent for good.

Superstitious fancies bear the same relation to truth that the shadow of a form does to the form itself. We know that the shadow has no substantial existence, and yet we know equally well that it is cast by some real body; in the same way we may be sure that, however foolish a superstition may appear to be, it has some foundation in fact. Indeed, superstition is associated with the highest attribute of the human mind,--imagination. The realities about us gain much of their charm from sentiment, and all that is great in art and literature owes its being to the transforming energy of pure imagination. Morbid imagination, on the other hand, distorts and degrades the impressions it receives and produces only unlovely or ignoble forms and ideas.
