This was comparatively easy, after the work that had already been performed. All the gods set to work catching sparks from Muspelheim, and there was great rivalry as to which one should collect most. Some of the sparks were scattered through the sky as stars, but the brightest ones were put aside and kept for a greater purposes. When enough had been gathered, the gods made from the whitely glowing ones the moon; from the fiery red and golden ones, the sun. These lights they placed in chariots, to which were harnessed swift, tireless steeds; but it was evident to all that the steeds could not be trusted to take the chariots across the sky unguided. Feeling that they could not spare two of their own number for this work, the gods chose Sol (sun) and Mani (moon), the daughter and son of a giant, who had named his children after the new lights because of their beauty. The young drivers were given instructions as to just the hours when they must begin their journeys across the sky, as to how rapidly they must drive, and as to the paths they must take; and never did the gods find reason to be dissatisfied with the work of Sol and Mani. Then two more chariots were made. To one was harnessed a black horse, named Hrimfaxi, whose mane dropped hoarfrost and whose bit scattered dew; while to the other was fastened the beautiful silver-white steed Skinfaxi, from whose shining mane beams of light were shed through all the earth. The giantess Night was entrusted with the first of these chariots, while the young god Day was made the driver of the other. Each was told to drive about the earth once each twenty-four hours. The gods could make all these beautiful things, but they could not keep the giants from making ugly and evil things; and so there were two fierce wolves, set on by the giants, who constantly chased the sun and moon across the sky, attempting to catch and devour them. Occasionally one of these wolves would overtake his prey, and would start to swallow it, thus producing what was known on earth as an eclipse. But always, in some way or other, they were frightened away before the light of the heavens was utterly destroyed. When the gods had expressed their pleasure in all that had so far been done, Odin said, "Where shall we fix our own dwelling? Beyond the earth, beyond the ocean, live the giants; but neither on the earth, nor in the earth, nor above the earth s there any living thing." "You mistake, Father Odin," cried one of his sons. "If you but look down, you will see that within the earth are many living things."
