We are told that in Tartary, each native makes the iron he needs, just as every household would make its own bread. The furnace is a very small affair, not holding more than three pounds of ore. This is filled with ore and charcoal. The bellows are used, and after the charcoal is all burned out, the result is a small piece of spongy iron, which needs only repeated heating and hammering to be made serviceable.

Starting with solar creation myths, this volume explores ancient ideology surrounding the sun and moon, solar mythology, and solar folklore. An extended analysis of sun worship around the world leads to accounts of sun-catcher myths and solar festivals. Solar omens, traditions, and superstitions are discussed at length, along with the solar significance of burial customs and emblematic and symbolic forms of the sun. The book concludes with a look at the sun in light of scientific discovery.
