(M302) This suspicion is confirmed when we examine the evils for which the bonfires and torches were supposed to provide a remedy. Foremost, perhaps, among these evils we may reckon the diseases of cattle; and of all the ills that witches are believed to work there is probably none which is so constantly insisted on as the harm they do to the herds, particularly by stealing the milk from the cows.(861) Now it is significant that the need-fire, which may perhaps be regarded as the parent of the periodic fire-festivals, is kindled above all as a remedy for a murrain or other disease of cattle; and the circumstance suggests, what on general grounds seems probable, that the custom of kindling the need-fire goes back to a time when the ancestors of the European peoples subsisted chiefly on the products of their herds, and when agriculture as yet played a subordinate part in their lives. Witches and wolves are the two great foes still dreaded by the herdsman in many parts of Europe;(862) and we need not wonder that he should resort to fire as a powerful means of banning them both. Among Slavonic peoples it appears that the foes whom the need-fire is designed to combat are not so much living witches as vampyres and other evil spirits,(863) and the ceremony, as we saw, aims rather at repelling these baleful beings than at actually consuming them in the flames. But for our present purpose these distinctions are immaterial. The important thing to observe is that among the Slavs the need-fire, which is probably the original of all the ceremonial fires now under consideration, is not a sun-charm, but clearly and unmistakably nothing but a means of protecting man and beast against the attacks of maleficent creatures, whom the peasant thinks to burn or scare by the heat of the fire, just as he might burn or scare wild animals.
(M303) Again, the bonfires are often supposed to protect the fields against hail(864) and the homestead against thunder and lightning.(865) But both hail and thunderstorms are frequently thought to be caused by witches;(866) hence the fire which bans the witches necessarily serves at the same time as a talisman against hail, thunder, and lightning. Further, brands taken from the bonfires are commonly kept in the houses to guard them against conflagration;(867) and though this may perhaps be done on the principle of homoeopathic magic, one fire being thought to act as a preventive of another, it is also possible that the intention may be to keep witch-incendiaries at bay. Again, people leap over the bonfires as a preventive of colic,(868) and look at the flames steadily in order to preserve their eyes in good health;(869) and both colic and sore eyes are in Germany, and probably elsewhere, set down to the machinations of witches.(870) Once more, to leap over the Midsummer fires or to circumambulate them is thought to prevent a person from feeling pains in his back at reaping;(871) and in Germany such pains are called "witch-shots" and ascribed to witchcraft.(872)
