The Prose Edda is an Old Norse work of literature written in Iceland in the early 13th century. The cosmology of Norse mythology has “nine homeworlds” or “nine realms”, unified by the world tree Yggdrasil. Mapping the nine worlds escapes precision because the Poetic Edda often alludes vaguely. The Norse creation myth tells how everything came into existence in the gap between fire and ice, and how the gods shaped the homeworld of humans.
