In the beginning of things, before there was any world or sun, moon, and stars, there were the giants; for these were the oldest creatures that ever breathed. They lived in Jotunheim, the land of frost and darkness, and their hearts were evil. Next came the gods, the good Æsir, who made earth and sky and sea, and who dwelt in Asgard, above the heavens. Then were created the queer little dwarfs, who lived underground in the caverns of the mountains, working at their mines of metal and precious stones. Last of all, the gods made men to dwell in Midgard, the good world that we know, between which and the glorious home of the Æsir stretched Bifröst, the bridge of rainbows.
