Pliny occasionally speaks in a vague general way of his citations from the _magi_ concerning the virtues of parts of animals as lies or nonsense or “portentous,” but he does not specifically criticize their procedure any more than he did their methods of employing herbs, and he does not criticize their promised results as much as he did before. Indeed, as we have already indicated, the object in a majority of cases is purely medicinal. The purpose of others is pastoral or agricultural, such as preventing goats from straying or causing swine to follow you.[252] The blood of the basilisk, however, is said to procure answers to petitions made to the powerful and prayers addressed to the gods, and to act as a safeguard against poison or sorcery (_veneficiorum amuleta_).[253] Invincibility is promised the wearer of the head and tail of a dragon, hairs from a lion’s forehead, a lion’s marrow, the foam of a winning horse, a dog’s claw bound in deer-skin, and the muscles alternately of a deer and a gazelle.[254] A woman will tell secrets in her sleep if the heart of an owl is applied to her right breast, and power of divination is gained by eating the still palpitating heart of a mole.[255] [Sidenote: The _magi_ on stones.] In the case of stones the names are again, as in the case of herbs, of little significance for us.[256] The accompanying ritual is slight. There are one or two suspensions from the neck or elsewhere by such means as a lion’s mane—the hair of the hyena will not do at all—nor the hair of the cynocephalus and swallows’ feathers.[257] There is some use of incantations with the stones, a setting of iron for one stone, burial of another beneath a tree that it may not dull the axe, and placing another on the tongue after rinsing the mouth with honey at certain days and hours of the moon in order to acquire the gift of divination.[258] Indeed, the results promised are all marvelous. The stones benefit public speakers, admit to the presence of royalty, counteract fascination and sorcery, avert hail, thunderbolts, storms, locusts, and scorpions; chill boiling water, produce family discord, render athletes invincible, quench anger and violence, make one invisible, evoke images of the gods and shades from the infernal regions.
