Loadstone
We have the authority of Plato (Ion, 533 D) for the statement that the word magnetis was first applied to the loadstone by the tragic poet Euripides (480-405 B.C.), the more usual name being “the Heraclean stone.” These designations refer to two places in Lydia, Magnesia and Herakleia, where the mineral was found.[120] Pliny states, on the authority of Nicander, that a certain Magnes, a shepherd, discovered the mineral on Mount Ida, while pasturing his flock, because the nails of his shoes clung to a piece of it.[121]
We are told by Pliny that Ptolemy Philadelphus (309-247 B.C.), planning to erect a temple in honor of his sister and wife Arsinoë, called in the aid of Chirocrates, an Alexandrian architect. The latter engaged to place therein an iron statue of Arsinoë which should appear to hang in mid-air without support. However, both the Egyptian king and his architect died before the design could be realized.[122] This story of an image held in suspense by means of powerful magnets set in the floor and roof, and sometimes also in the walls of a temple, is repeated in a variety of forms by early writers. Of course, there was no real foundation for such tales, as the thing is altogether impracticable.
The Roman poet Claudian (fifth century A.D.) relates that the priests of a certain temple, in order to offer a dramatic spectacle to the eyes of the worshippers, caused two statues to be executed,—one of Mars in iron, and another of Venus in loadstone. At a special festival these statues were placed near to each other, and the loadstone drew the iron to itself. Claudian vividly describes this:
The priests prepare a marriage feast.
Behold a marvel! Instant to her arms
Her eager husband Cythereia charms;
And ever mindful of her ancient fires,
With amorous breath his martial breast inspires;
Lifts the loved weight, close round his helmet twines
Her loving arms, and close embraces joins,
Drawn by the mystic influence from afar.
Flies to the wedded gem the God of War.
The Magnet weds the Steel: the sacred rites
Nature attends, and th’ heavenly pair unites.[123]
There was current as early as the fourth century a curious belief that a piece of loadstone, if placed beneath the pillow of a sleeping wife, would act as a touchstone of her virtue. This first appears in the Alexandrian poem “Lithica,” and it has been thus quaintly Englished by a fourteenth century translator:
Also magnes is in lyke wyse as adamas; yf it be sett under the heed of a chaste wyfe, it makyth her sodenly to beclyppe [embrace] her husbonde; & yf she be a spowse breker, she shall meve her oute of the bed sodenly by drede of fantasy.[124]
The same writer attempts an explanation of the popular fancy that when powdered loadstone was thrown upon coals in the four corners of a house, the inmates would feel as though the house were falling down; of this he says: “That seemynge is by mevynge [moving] that comyth by tornynge of the brayn.”[125]
In classical writings the fascination exercised by a very beautiful woman is sometimes likened to the attractive power of the loadstone, as notably by Lucian,[126] who says that if such a woman looks at a man she draws him to her, and leads him whither she will, just as the loadstone draws the iron. To the same idea is probably due the fact that in several languages the name given to the loadstone indicates that its peculiar power was conceived to be a manifestation of the sympathy or love of one mineral substance for another. This is commonly believed to be the sense in which we should understand the French designation aimant, namely, as the participle of the verb aimer, “to love”; however, some etymologists prefer to derive the word from adamas, sometimes used in Low Latin for the loadstone, although properly signifying the diamond. It is certainly worthy of note that in two such dissimilar languages as Sanskrit and Chinese, the influence of this idea appears in the names given to the loadstone. In Sanskrit the word is chumbaka or “the kisser,” and in Chinese t’ su shi, or “the loving-stone.” Chin T’sang Khi, a Chinese author of the eighth century, wrote that “the loadstone attracts iron just as does a tender mother when she calls her children to her.”[127]
A rich growth of Mohammedan legends grew up about the exploits of Alexander the Great, a striking example being given on another page, and in one of them it is related that the Greek world-conqueror provided his soldiers with loadstones as a defence against the wiles of the jinns, or evil spirits; the loadstone, as well as magnetized iron, being regarded as a sure defence against enchantments and all the machinations of malignant spirits.[128]
In the East Indies it is said that a king should have a seat of loadstone at his coronation; probably because the magnetic influence of the stone was supposed to attract power, favor, and gifts to the sovereign. But it is not only in the Orient that magnetite is prized for its talismanic powers, for even in some parts of our own land this belief is still prevalent. Large quantities of loadstone are found at Magnet Cove, Arkansas, and it is estimated that from one to three tons are sold annually to the negroes to be used in the Voodoo ceremonies as conjuring stones. The material has been found in land used for farming purposes, and many pieces have been turned up in ploughing for corn; these vary from the size of a pea to masses weighing from ten to twenty pounds. They occur in a reddish-brown, sticky soil; their surface is smooth and brown and they have the appearance of water-worn pebbles. In July, 1887, an interesting case was tried in Macon, Georgia, where a negro woman sued a conjuror to recover five dollars which she had paid him for a piece of loadstone to serve as a charm to bring back her wandering husband. As the market value of this mineral was only seventy-five cents a pound, and the piece was very small, weighing but a few ounces, the judge ordered that the money should be refunded.[129]
