Horses that, feeding on the grassy hills, tread upon moonwort with their hollow heels, though lately shod, at night go barefoot home, their maister musing where their shoes become. O moonwort! tell me where thou hid’st the smith, hammer and pinchers, thou unshodd’st them with.
The horse-shoe has sometimes been identified with the cross, and has been supposed to derive its amuletic power from a fancied resemblance to the sacred Christian symbol. But inasmuch as it is difficult to find any marked similarity in form between the crescent and the cross, this theory does not appear to warrant serious consideration.
VI. IRON AS A PROTECTIVE CHARM
Some writers have maintained that the luck associated with the horse-shoe is due chiefly to the metal, irrespective of its shape, as iron and steel are traditional charms against malevolent spirits and goblins. In their view, a horse-shoe is simply a piece of iron of graceful shape and convenient form, commonly pierced with seven nail-holes (a mystic number), and therefore an altogether suitable talisman to be affixed to the door of dwelling or stable in conformity with a venerable custom sanctioned by centuries of usage. Of the antiquity of the belief in the supernatural properties of iron there can be no doubt.
Among the ancient Gauls this metal was thought to be consecrated to the Evil Principle, and, according to a fragment of the writings of the Egyptian historian Manetho (about 275 B. C.), iron was called in Egypt the bone of Typhon, or Devil’s bone, for Typhon in the Egyptian mythology was the personification of evil.[58]
Pliny, in his “Natural History,” states that iron coffin-nails affixed to the lintel of the door render the inmates of the dwelling secure from the visitations of nocturnal prowling spirits.
According to the same author, iron has valuable attributes as a preservative against harmful witchcrafts and sorceries, and may thus be used with advantage both by adults and children. For this purpose it was only necessary to trace a circle about one’s self with a piece of the metal, or thrice to swing a sword around one’s body. Moreover, gentle proddings with a sword wherewith a man has been wounded were reputed to alleviate divers aches and pains, and even iron-rust had its own healing powers:—
If a horse be shod with shoes made from a sword wherewith a man has been slain, he will be most swift and fleet, and never, though never so hard rode, tire.[59]
The time-honored belief in the magical power of iron and steel is shown in many traditions of the North.
A young herdswoman was once tending cattle in a forest of Vermaland in Sweden; and the weather being cold and wet, she carried along her tinder-box with flint and steel, as is customary in that country. Presently along came a giantess carrying a casket, which she asked the girl to keep while she went away to invite some friends to attend her daughter’s marriage. Quite thoughtlessly the girl laid her fire-steel on the casket, and when the giantess returned for the property she could not touch it, for steel is repellant to trolls, both great and small. So the herdswoman carried home the treasure-box, which was found to contain a golden crown and other valuables.[60]
