Primitive ideas about life and existence are neither congruous with our concepts nor diametrically opposed to our science and psychology. The belief in souls does not include personification of natural objects, but on the other hand it does not exclude the possibility that Sun and Earth may assume a human-like appearance. In Scandinavia, nature is peopled by powers in human shape. Up from the earth and out from the hills elf and dwarf peer forth, a host of giants bellow from the mountains, from the sea answer Ran's daughters, those enticing and hardhearted wave-maidens, with their cruel mother, and at home in the hall of the deep sits venerable Ægir. Over the heavens go sun and moon; some indeed declare that the two drive in chariots with steeds harnessed to their carts; the sun is chased by two wolves eager to swallow its shining body. Of the sun and the moon it is said, both that they were given and taken in marriage, and that they have left offspring.
