Page "Bifröst" Paragraph 1

In Norse mythology, Bifröst ( or sometimes Bilröst ) is a burning rainbow bridge that reaches between Midgard ( the world ) and Asgard, the realm of the gods.

The bridge is attested as Bilröst in the Poetic Edda ; compiled in the 13th century from earlier traditional sources, and as Bifröst in the Prose Edda ; written in the 13th century by Snorri Sturluson, and in the poetry of skalds.

Both the Poetic Edda and the Prose Edda alternately refer to the bridge as Asbrú ( Old Norse " Æsir's bridge ").
