Hallucination may also be produced by artificial means, and there are evidences afforded by the confessions of those tried for lycanthropy, that these artificial means were employed by them. I refer to the salve so frequently mentioned in witch and were-wolf trials. The following passage is from the charming _Golden Ass of Apuleius_; it proves that salves were extensively used by witches for the purpose of transformation, even in his day:—
“Fotis showed me a crack in the door, and bade me look through it, upon which I looked and saw Pamphile first divest herself of all her garments, and then, having unlocked a chest, take from it several little boxes, and open one of the latter, which contained a certain ointment. Rubbing this ointment a good while previously between the palms of her hands, she anointed her whole body, from the very nails of her toes to the hair on the crown of her head, and when she was anointed all over, she whispered many magic words to a lamp, as if she were talking to it. Then she began to move her arms, first with tremulous jerks, and afterwards by a gentle undulating motion, till a glittering, downy surface by degrees overspread her body, feathers and strong quills burst forth suddenly, her nose became a hard crooked beak, her toes changed to curved talons, and Pamphile was no longer Pamphile, but it was an owl I saw before me. And now, uttering a harsh, querulous scream, leaping from the ground by little and little, in order to try her powers, and presently poising herself aloft on her pinions, she stretched forth her wings on either Side to their full extent, and flew straight away.
“Having now been actually a witness of the performance of the magical art, and of the metamorphosis of Pamphile, I remained for some time in a stupefied state of astonishment. . . . At last, after I had rubbed my eyes some time, had recovered a little from the amazement and abstraction of mind, and begun to feel a consciousness of the reality of things about me, I took hold of the hand of Fotis and said,—‘Sweet damsel, bring me, I beseech thee, a portion of the ointment with which thy mistress hath just now anointed, and when thou hast made me a bird, I will be thy slave, and even wait upon thee like a winged Cupid.’ Accordingly she crept gently into the apartment, quickly returned with the box of ointment, hastily placed it in my hands, and then immediately departed.
