The details of the rites and the full forms of incantation are in general extremely difficult to obtain. The witches themselves are always reticent on such points, and I have known one plead, by way of excuse for her apparent discourtesy in withholding information, that the virtue of magic was diminished in proportion as the knowledge of it was disseminated. One cure, however,--a cure for headache--will sufficiently illustrate the principle on which the healing art among the common-folk generally proceeds. This cure is based upon the assumption that the tense and bruised feeling of a bad headache is due to the presence of some demon within the skull, and that the room which he occupies must have been provided by distention of the head,--which will therefore measure more in circumference while it aches than when the demon has been exorcised. This is demonstrated in the course of the cure. The witch takes a handkerchief and measures with it the patient’s head. Doubling back the six or eight inches of the handkerchief that remain over, she puts in the fold three cloves of garlic, three grains of salt, or some other article of magical virtue, and ties a knot. Then waving the handkerchief about the patient’s head, she recites her form of exorcism,--but usually in a tone so low and mumbling that the bystanders cannot catch the words. The exorcism being finished, she again measures the head, and this time the knot, which marks the previous measurement, is found to overlap, by two or three inches it may be, the other end of the kerchief,--a sure sign that the intruding demon has been expelled and that the head having returned to its natural dimensions will no longer ache[30]. The exact words of the incantation which should accompany this rite I could not obtain; but I make little doubt that in substance they would differ little from a Macedonian formula recently published:-- ‘For megrim and headache: ‘Write on a piece of paper:--God of Abraham, God of Isaac, God of Jacob, loose the demon of the megrim from the head of Thy servant. I charge thee, unclean spirit which ever sittest in the head of man, take thy pain and depart from the head: from half-head, membrane, and vertebra, from the servant of God, So-and-so. Stand we fairly, stand we with fear of God. Amen[31].’ In this instance we have the formula but not, it seems, the rite which should accompany it; for the mere act of committing the words to paper is hardly likely to be deemed sufficient. Probably the paper would be laid under the pillow at night, or, as I have known in other cases, would be burnt, and its ashes taken as a sedative powder.
