About Superstitions and the History of Toad Stones

While some believed that the toad-stone was vomited by the animal, others held that it constituted a part of the toad's head. That this was the popular belief in Shakespeare's time is shown by the well-known lines in his "As You Like It" (Act II, sc. 1):

Which like the toad, ugly and venomous,

Wears yet a precious jewel in his head.

De Boot, whose treatise was published about the time that Shakespeare wrote these lines, gives the following account of the result of his efforts to obtain a toad-stone according to the prescribed method:

I remember that, when a boy, I took an old toad and set it upon a red cloth that I might secure a toadstone; for they say that it will not give up its stone unless it sits upon a red cloth. However, although I watched the toad for a whole night, it did not eject anything, and from this time I became convinced all the tales concerning this stone were merely fond imaginings.

A stone called simply the "Indian Stone," and said to be light and porous, is noted by pseudo-Aristotle, and to it is attributed the power to relieve those suffering from dropsy, by drawing the water to itself. If weighed after having been applied to the patient, the stone was found to have increased in weight in proportion to the amount of water absorbed, and when it was placed in the sun, water of a yellowish hue exuded, until, finally, the stone resumed its original appearance and weight. Another and perhaps earlier authority gives the name "toad-stone" to this material.

The toad-stone was not only an antidote for poisons, but was also thought to give warning of their presence by becoming very hot. To fully profit by this strange quality, the wearer of such a stone was advised to have it so set in a ring that it would touch the skin; in this way he would be sure to have timely notice, if any poisoned food or drink were offered to him. The writer who mentions this adds the following tale of the discovery of a toad-stone:

A clerk once found a toad which had a round knob on its head, wherefore he thought that there must be a toad-stone. So he took up the toad and tied it firmly in the sleeve of his coat. When he returned from the fields and searched for the toad he found it not, although the sleeve of his coat was tightly bound below and he could not discover any opening through which the creature could have passed. This shows us that it is a great help to prisoners in jail.

Another early authority, Thomas de Cantimpre, says of the toad-stone:

If one take the stone from a living and still quivering toad a little eye can be seen in the substance; but if it be taken from a toad that has been some time dead, the poison of the creature will have already destroyed this little eye and spoiled the stone.

If the toad-stone be swallowed at meal-time it passes through the system and carries off all impurities. Here the substance may have been one of many concretionary materials,--bauxite, impure pearls, concretionary limestone, stalagmite, or even the eye-stones from the crawfish; indeed, any material, white or gray, that had a semblance to a toad color, and was then sold by the vendor of charm stones as coming from a toad's head.

The great Erasmus (1465-1536) made a pilgrimage to the famous shrine of the Virgin in the church at Walsingham, in Kent. In his description of what he saw there he expressly notes a wonderful toad-stone:

At the feet of the Virgin is a gem for which there is as yet no Latin or Greek name. The French have named it after the toad [crapaudine], because it represents so perfectly the figure of a toad that no art could do this so well. The miracle is all the greater that the stone is so small, and that the exterior surface has not the form of a toad, the image showing through it as though inclosed within.

As we see, the stone of Erasmus contained the form or image of a toad. This was not usually the case with the concretions that bore this name, and it appears probable that the "crapaudine" of the shrine at Walsingham owed its peculiarity rather to art than to nature. A rather farfetched explanation of the origin of these substances is given by Ambrosianus, who relates that, in order to investigate the quality and character of toad-stones, he killed a number of toads and took out their brains. Although these were not hard when extracted, they became, in time, as hard as stones.

A toad-stone which appeared to represent the form of this animal was preserved as an heirloom in the Lemnian family. It exceeded the size of a walnut and was often seen to dissipate the swelling caused by the bite of a venomous creature in any part of the body, if it were rubbed quickly over the swelling. It, therefore, seemed to possess the same quality as was attributed to the animal from which it was taken, namely, to draw out and annul all poisons. If any neighbor of the Lemnian family were bitten by a mouse, a spider, a dormouse, a wasp, a beetle, or any such creature, he soon sought the aid of this stone.

We have noted De Boot's unsuccessful attempt to secure a toad-stone, but he does not seem to have used the orthodox method for obtaining it. According to one authority, the creature should be placed in a cage covered with a red cloth and then set in the hot sunshine for several days, until thirst forced the poor toad to eject his precious stone, which was to be removed as soon as possible lest it should be swallowed again. Another method proposed is so cruel that it is a comfort to know that the whole matter is little more than a fanciful conceit. In this case, the toad was to be enclosed in a pot with many perforations, and the vessel with its unlucky inmate was then to be placed in an ant-hill and left there until nothing remained of the toad except his bones and the coveted stone. It is quite probable that any stone found in an ant-hill after this procedure would be termed a "toad-stone," since the toad was put away in order to find one. In some instances they may have been bony concretions from the head of the toad, or even pebbles that the toad had swallowed.
