What animals to eat and wear.
Hildegard gives some strange advice what animal products to eat and wear. “Sheepskins are good for human wear, because they do not induce pride or lust or pestilence as the skins of certain other animals do.”[423] Pork is not good for either sick or healthy persons to eat, in her opinion, while beef, on account of its intrinsic cold, is not good for a man of cold constitution to eat.[424] On the other hand, she recommends as edible various birds which would strike the modern reader as disgusting.[425]
Insects and reptiles.
Fleas remain underground in winter but come forth to plague mankind when the sun dries the soil in summer. But one may be rid of them by heating some earth until it is quite dry and then scattering it upon the bed.[426] Hildegard also describes a complicated cure for leprosy by use of the earth from an ant-hill.[427] If a man kills a certain venomous snake just after it has skinned itself in the cleft of a rock, and cautiously removes its heart and dries the same in the sun, and then preserves it in a thin metal cover, it will serve as an amulet. Holding it in his hand will render him immune to venom and cheer him up if he becomes gloomy or sorrowful.[428]
Animal compounds.
In the Causae et curae Hildegard combines the virtues of parts of a number of animals into one composite medicine for epilepsy.[429] Four parts of dried mole’s blood are used because the mole sometimes shows himself and sometimes hides, like the epilepsy itself. Two parts of powdered duck’s bill are added because the duck’s strength is in its beak, “and because it touches both pure and impure things with its bill, it is repugnant to this disease which is sudden and silent.” One portion of the powdered claws of a goose, minus the skin and flesh, is added for much the same reason, and the claw of a goose rather than a gander is required because the female bird is the more silent of the two. These constituents are bound together in a cloth, placed for three days near a recent molecast,—for such earth is more wholesome, then are put near ice to cool and then in the sun to dry. Cakes are then to be made with this powder and the livers of some edible animal and bird and a little meal and cummin seed, and eaten for five days. Against diabolical phantasms is recommended a belt made of the skin of a roebuck, which is a pure animal, and of the skin of the helun, which is a brave beast, and hence both are abhorred by evil spirits.[430] The two strips of skin are to be fastened together by four little steel[431] nails, and as each is clasped one repeats the formula, “In the most potent strength of almighty God I adjure you to safeguard me”; only in the second, third, and fourth instance instead of saying “I adjure” (adiuro), the words benedico, constituo, and confirmo are respectively substituted. One should be girded with this belt night and day, and magic words will not harm one.
Magic and astrology closely connected.
We have already encountered more than one instance of observance of the phases of the moon in Hildegard’s medicinal and magical procedure, and have met in one of her formulae a hint that Christ employed astrological election of a favorable conjunction in performing His miracles. Thus as usual the influence of the stars is difficult to separate from other occult virtues of natural substances, and we may complete our survey of Hildegard’s writings by considering her views concerning the celestial bodies and divination of the future.
Astrology and divination condemned.
In the passage of the Scivias to which we have already referred God condemned astrology and divination as well as magic.[432] Mathematici are called “deadly instructors and followers of the Gentiles in unbelief,” and man is reproved for believing that the stars allot his years of life and regulate all human actions, and for cultivating in the place of his Creator mere creatures such as the stars and heavens, which cannot console or help him, or confer either prosperity or happiness. Man should not consult the stars as to the length of his life, which he can neither know beforehand nor alter. He should not seek signs of the future in either stars or fire or birds or any other creature. “The error of augury” is expressly rebuked. Man should abstain not only from worshiping or invoking the devil but from making any inquiries from him, “since if you wish to know more than you should, you will be deceived by the old seducer.”
