The heathen Northmen believed in the existence of a race of dwarfish artisans, who were skilled in the working of metals, and who fashioned implements of warfare in their subterranean workshops. These dwarfs were also thought to inhabit isolated rocks; and according to a popular notion, if a man chanced to encounter one of them, and quickly threw a piece of steel between him and his habitation, he could thereby prevent the dwarf from returning home, and could exact of him whatever he desired.[61]
Among French Canadians, fireflies are viewed with superstitious eyes as luminous imps of evil, and iron and steel are the most potent safeguards against them; a knife or needle stuck into the nearest fence is thought to amply protect the belated wayfarer against these insects, for they will either do themselves injury upon the former, or will become so exhausted in endeavoring to pass through the needle’s eye as to render them temporarily harmless.[62] Such waifs and strays of popular credulity may seem most trivial, yet they serve to illustrate the ancient and widely diffused belief in the traditional qualities ascribed to certain metals.
One widely prevalent theory ascribed to iron a meteoric origin, but the different nations of antiquity were wont to attribute its discovery or invention to some favorite deity or mythological personage; Osiris was thus honored by the Egyptians, Vulcan by the Romans, and Wodan or Odin by the Teutons.
In early times the employment of iron in the arts was much restricted by reason of its dull exterior and brittleness. There existed, moreover, among the Romans a certain religious prejudice against the metal, whose use in many ceremonies was wholly proscribed. This prejudice appears to have been due to the fact that iron weapons were held jointly responsible with those who wielded them for the shedding of human blood; inasmuch as swords, knives, battle-axes, lance and spear points, and other implements of war were made of iron.[63]
Those mythical demons of Oriental lands known as the Jinn are believed to be exorcised by the mere name of iron;[64] and Arabs when overtaken by a simoom in the desert endeavor to charm away these spirits of evil by crying, “Iron, iron!”[65]
The Jinn being legendary creatures of the Stone Age, the comparatively modern metal is supposed to be obnoxious to them. In Scandinavia and in northern countries generally, iron is a historic charm against the wiles of sorcerers.
The Chinese sometimes wear outside of their clothing a piece of an old iron plough-point as a charm;[66] and they have also a custom of driving long iron nails in certain kinds of trees to exorcise some particularly dangerous female demons which haunt them.[67] The ancient Irish were wont to hang crooked horse-shoe nails about the necks of their children as charms;[68] and in Teutonic folk-lore we find the venerable superstition that a horse-shoe nail found by chance and driven into the fireplace will effect the restoration of stolen property to the owner. In Ireland, at the present time, iron is held to be a sacred and luck-bringing metal which thieves hesitate to steal.[69]
A Celtic legend says that the name Iron-land or Ireland originated as follows: The Emerald Isle was formerly altogether submerged, except during a brief period every seventh year, and at such times repeated attempts were made by foreigners to land on its soil, but without success, as the advancing waves always swallowed up the bold invaders. Finally a heavenly revelation declared that the island could only be rescued from the sea by throwing a piece of iron upon it during its brief appearance above the waters. Profiting by the information thus vouchsafed, a daring adventurer cast his sword upon the land at the time indicated, thereby dissolving the spell, and Ireland has ever since remained above the water. On account of this tradition the finding of iron is always accounted lucky by the Irish; and when the treasure-trove has the form of a horse-shoe, it is nailed up over the house door. Thus iron is believed to have reclaimed Ireland from the sea, and the talismanic symbol of its reclamation is the iron horse-shoe.[70]
Once upon a time—so runs a tradition of the Ukraine, the border region between Russia and Poland—some men found a piece of iron. After having in vain attempted to eat it, they tried to soften it by boiling it in water; then they roasted it, and afterwards beat it with stones. While thus engaged, the Devil, who had been watching them, inquired, “What are you making there?” and the men replied, “A hammer with which to beat the Devil.” Thereupon Satan asked where they had obtained the requisite sand; and from that time men understood that sand was essential for the use of iron-workers; and thus began the manufacture of iron implements.[71]
