The power which the witch was supposed to possess of transporting herself from place to place, and which those self-deluded wretches themselves believed; and the orgies of the witch-sabbath, which were again and again deposed to, were hallucinations due to a form of insanity—for we may so call it—prevailing at the period, which was determined by the nature of the superstitious beliefs entertained. The real character of this superstition is well shown by an incident which is recorded by Jung-Stilling.

He writes:—"I am acquainted with a tale, for the truth of which I can vouch, because it is taken from the official documents of an old witch-process. An old woman was imprisoned, put to the torture, and confessed all that witches are generally charged with. Amongst others, she also denounced a neighbour of hers, who had been with her on the Blocksberg, the preceding Walpurgis night. This woman was called, and asked if it were true what the prisoner said of her? On which she stated that, on Walpurgis eve she had called upon this woman, because she had something to say to her. On entering her kitchen, she found the prisoner busy in preparing a decoction of herbs. On asking her what she was boiling, she said, with a smiling and mysterious mien, "Wilt thou go with me to the Brocken?" From curiosity, and in order to ascertain what there was in the matter, she answered, "Yes: I should like to go well enough." On which the prisoner chattered some time about the feast, and the dance, and the enormous goat. She then drank of the decoction, and offered it to her, saying: "There, take a hearty drink of it, that thou mayest be able to ride through the air:" she likewise put the pot to her mouth, and made as if she drank of it, but did not taste a drop. During this, the prisoner had put a pitchfork between her legs, and placed herself upon the hearth; that she soon sunk down, and began to sleep and snore: after having looked on for some time, she was at length tired of it, and went home.

The next morning, the prisoner came to her, and said, "Well, how dost thou like being at the Brocken? Sith, there were glorious doings." On which she had laughed heartily, and told her that she had not drunk of the potion, and that she, the prisoner, had not been at the Brocken, but had slept with her pitchfork upon the hearth. That the woman, on this, became angry, and said to her, that she ought not to deny having been at the Brocken, and having danced and kissed the goat."[66]

Gassendi relates an experiment to the same effect. He anointed some peasants with a pomade made of belladonna or opium, persuading them that the operation would convey them to the witch-sabbath. After a profound sleep, they awoke, and told how they had been present at the sabbath, and the pleasures they had enjoyed.

Stupifying and intoxicating drugs were, in all probability, freely used by sorcerers, and in the ancient mysteries, and to their use is to be attributed many of the illusions and hallucinations which are familiar in the details of the practice of the occult sciences.

Jung-Stilling quotes a singularly interesting example of a method of practising one of the most important processes of magic; and an examination of it satisfactory shows the manner in which some of the most striking of the deceptions of that art were brought about, and how it happened that the professor, as well as the student, was equally deluded.

In Eckhartshausen's "Key to Magic" there is an account of a young Scotsman "who, though he meddled not with the conjuration of spirits, and such like charlatanry, had learned, however, a remarkable piece of art from a Jew, which he communicated also to Eckhartshausen, and made the experiment with him,—which is surprising, and worthy of perusal. He that wishes to raise and see any particular spirit, must prepare himself for it, for some days together, both spiritually and physically. There are also particular and remarkable requisites and relations necessary betwixt such a spirit and the person who wishes to see it—relations which cannot otherwise be explained, than on the ground of the intervention of some secret influence from the invisible world. After all these precautions, a vapour is produced in a room, from certain materials which Eckhartshausen, with propriety, does not divulge, on account of the dangerous abuse which might be made of it, which visibly forms itself into a figure which bears a resemblance to that which the person wishes to see. In this there is no question of any magic-lantern or optical artifice; but the vapour really forms a human figure, similar to that which the individual desires to behold. I will now insert the conclusion of the story in Eckhartshausen's own words:—

"Some time after the departure of the stranger, that is, the Scotsman, I made the experiment for one of my friends. He saw as I did, and had the same sensations.

"The observations that we made were these. As soon as the ingredients were thrown into the chafing-dish, a whitish body forms itself, that seems to hover above the chafing-dish, as large as life.
