These fabled stag’s tears, though often praised as substitutes for the bezoar, were not believed in by all the early writers, one of them, Rollenhagen, giving expression to a caustic opinion that might do credit to a writer of our own day. Alluding to the many reports of the existence of such “tears,” shed by the animals because of the pains they suffered after indulging in a diet of serpents, he notes that all those who make these statements are careful to place the habitat of these eccentric stags as far away from their own land as possible, always “somewhere in the Orient,” probably at “Nowheretown,” as he adds.[[348]]

Types of cheloniæ (tortoise-stones). Natural concretions. From Aldrovandi’s “Museum metallicum,” Bononiæ, 1648.

The chelonia is said by Pliny to have been the eye of the Indian tortoise. The magicians asserted that this was the most marvellous of all “stones”; for if bathed in honey and then placed in the mouth, when the moon was either full or new, it conferred the power of divination, and this power lasted for one entire day.[[349]] This virtue was not, however, altogether peculiar to the chelonia, for it was shared by several other substances; in each case the stone was to be placed in the mouth, thus coming into more immediate contact with the organs of speech, and stimulating to prophetic utterance. A later writer states that it was the uterine stone from the tortoise that gave the gift of prophecy. That from the head cured headaches and averted lightning, while the stone taken from the liver, if administered in solution, was a remedy for ague.[[350]]

The wild ass was another of the animals that furnished concretions prized for their talismanic and medicinal powers. That taken from the animal’s head cured headache and epilepsy; that from the jaw made the owner indefatigable, so that he yielded to none in battle. It was also a remedy for ague and for the bites of venomous creatures, as well as a marvellously efficacious vermifuge for children.[[351]] Very likely the story of Samson, who wrought such slaughter among the Philistines when armed with the jawbone of an ass, may have suggested the fancy that the concretion from the ass’s jaw would give victory to the wearer.

Chelidonius, or “Swallow-stones.” From “Museum Wormianum,” Lugduni Batavorum, 1655.

Pliny notes the opinion that a stone taken from the body of a young swallow, if worn attached to the human body, helps to strengthen the brain, and he adds that the stone is said to be found in the young bird even when it has just broken the shell.[[352]] According to Thomas de Cantimpré the swallow-stone is a talisman for merchants and tradesmen.[[353]] The merits of the chelidonius, as this stone was called, were fully recognized in Saxon England and are given due prominence in an Anglo-Saxon medical treatise, dating from the first half of the tenth century. When these “swallow-stones” had been obtained they were to be carefully protected from contact with water, earth, or other stones. To secure the best results three of them were to be applied to the person who stood in need of their remedial effects. Not only did they cure headache and eye-smart, but they banished the dreaded nightmare, rendered futile the wiles of goblin visitors, and dissolved all fascinations and enchantments. The seekers after these wonderful stones are stoutly assured that they can only be found in “big nestlings.”[[354]]

The ætites (eagle-stone) is first mentioned by Pliny who states that it was found in the nests of eagles of a certain species, and adds that some called this stone gangites. Fire had no power over it and it was a useful remedy for many diseases. Its special virtue, however, was to prevent abortion, this use being suggested by the character of the stone itself, which “was as though pregnant, for when it was shaken another stone rattled within it, as though in a womb.” The curative virtues of the ætites, like that of the swallow-stone, only existed when the stone was taken from the bird’s nest. This was probably a story told by the vendors of such geodes to enhance the value of their wares, although there may have been some foundation for it in folk-lore.

They are really hollow concretions of an iron stone, containing a piece of loose iron or hardened sand, or a concretion of some kind that rattles, and is called by the Italians bambino or “babe.” Such concretions are found at many places on every continent, many fine ones having been found in Delaware. They vary in size from one to six inches across. The small ones of a hard, smooth exterior that have become polished from wear, are especially valued as charms.[[355]]
