Numbers in Germanic paganism in the context of Blót

In Norse mythology, Ask and Embla (Old Norse: Askr ok Embla)—man and woman respectively—were the first two humans, created by the gods. The pair are attested in both the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, composed in the 13th century. In both sources, three gods, one of whom is Odin, find Ask and Embla and bestow upon them various corporeal and spiritual gifts. A number of theories have been proposed to explain the two figures, and there are occasional references to them in popular culture.

In Norse mythology, Mímisbrunnr (Old Norse "Mímir's wellspring") is a spring or well associated with the being Mímir, located beneath the world tree Yggdrasil. Mímisbrunnr is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. The wellspring is located beneath one of three roots of the world tree Yggdrasil, a root that passes into the Jötunheimr where the primordial plane of Ginnungagap once existed. In addition, the Prose Edda relates that the water of the wellspring contains much wisdom, and that Odin sacrificed one of his eyes to the wellspring in exchange for a drink. In the Prose Edda, Mímisbrunnr is mentioned as one of three wellsprings existing beneath three roots of Yggdrasil, the other two being Hvergelmir, located beneath a root in Niflheim, and Urðarbrunnr.

Urðarbrunnr (Old Norse "Wellspring of Urðr"; either referring to a Germanic concept of fate—urðr—or the norn named Urðr) is a spring or well in Norse mythology. Urðarbrunnr is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, the wellspring lies beneath the world tree Yggdrasil, and is associated with a trio of norns (Urðr, Verðandi, and Skuld). In the Prose Edda, Urðarbrunnr is cited as one of three wellsprings existing beneath three roots of Yggdrasil that reach into three distant, different lands; the other two wellsprings being Hvergelmir, located beneath a root in Niflheim, and Mímisbrunnr, located beneath a root near the home of the frost jötnar. Scholarly theory and speculation surrounds the wellspring.
