The horse-shoe is a product of the artisan’s skill by the aid of fire.
This element has in all ages been considered the great purifier, and a powerful foe to evil spirits.[111]
The Chaldeans venerated fire and esteemed it a deity, and among primitive nations everywhere it has ever been held sacred. The Persians had fire-temples, called Pyræa, devoted solely to the preservation of the holy fire.[112]
In the “Rig-Veda,” the principal sacred book of the Hindus, the crackling of burning fagots was listened to as the voice of the gods, and the same superstition prevails still among the natives of Borneo.[113]
In a fragment of the writings of Menander Protector, a Greek historian of the sixth century, it is related that when an embassy sent by the Emperor Justin reached Sogdiana, the ancient Bokhara, it was met by a party of Turks, who proceeded to exorcise their baggage by beating drums and ringing bells over it. They then ran around the baggage, bearing aloft flaming leaves, meantime, by their gestures and movements, seeking to repel evil spirits; after which some of the party themselves passed through fire as a means of purification.[114]
Fire is especially potent against nocturnal demons, and also against the evil spirits which cause disease in cattle. Hence the utility of the ancient “need-fires,” produced by the friction of two pieces of wood, which were thought to be an antidote against the murrain and epizoötics generally,—a custom until recently in vogue in the Scottish Highlands, and formerly practiced in many other regions.
The midsummer fires kindled on Saint John’s Eve, in accordance with an ancient British custom, were regarded as purifiers of the air. Moreover, the whole area of ground illuminated by these fires was reckoned to be freed from sorcery for a year, and, by leaping through the flames, both men and cattle were insured safety against demons for a like period.[115]
In Ireland it was customary for people to run through the streets on Saint John’s Eve carrying long poles, upon which were tied flaming bundles of straw, in order to purify the air, for at that time all kinds of mischievous imps, hobgoblins, and devils were abroad, intent on working injury to human beings.[116]
Midsummer fires were still lighted in Ireland in the latter half of the nineteenth century, a survival of pagan fire-worship. In many countries people gathered about the bonfires, while children leaped through the flames, and live coals were carried into the cornfields as an antidote to blight.[117]
Sometimes the remaining ashes were scattered over the neighboring fields, in order to protect the crops from ravaging vermin or insects; and in Sweden the smoke of need-fires was reputed to stimulate the growth of fruit-trees, and to impart luck to fishing-nets hung up in it.[118]
