Norse cosmology

Norse cosmology is the account of the universe and its laws by the ancient North Germanic peoples. The topic encompasses concepts from Norse mythology, such as notions of time and space, cosmogony, personifications, anthropogeny, and eschatology. Like other aspects of Norse mythology, these concepts are primarily recorded in the Poetic Edda, a collection of poems compiled in the 13th century, and the Prose Edda, authored by Icelander Snorri Sturluson in the 13th century, who drew from earlier traditional sources. Together these sources depict an image of Nine Worlds around a cosmic tree, Yggdrasil.
