Bifrost in Odinism is the bridge leading from the realm of humans, Midgard, to the realm of the gods, Asgard, which the gods travel daily to hold their councils and pass judgements at the (Well of Urd) under the shade of the tree Yggdrasill.
The bridge itself is the rainbow and its guardian is the god Heimdallr, whose hall of Himinbjorg is located at the upper end of the bridge. The red color was the flaming fire, which served as a defense against the giants. The bridge is destroyed at the end of the world, Ragnarok. It was built by the Æsir.
Much of what we know concerning Bifröst comes from Snorri Sturluson (quoted below), but mention of it is also made in the Poetic Edda. For example, in Grímnismál, stanza 29 mentions Thor crossing over rivers (such as the Körmt and Örmt and the "Kerlaugs twain") which boil from the fire of Bifröst each day on his way to the judgement place at Yggdrasil, and later in stanza 44 it is named as the best of bridges in a list of the foremost of things (including Yggdrasil of trees, Sleipnir of horses, etc.). In Fáfnismál, stanza 15 (as well as Snorri) indicates that it will collapse when ridden upon by the fire giants during the destruction of Ragnarök.
Some scholars argue that Bifröst may have originally represented the Milky Way and was reinterpreted by Snorri as a rainbow when confronted with variations in terminology.
The Prose EddaEdit
- Then said Gangleri: "What is the way to heaven from earth?"
- Then Hárr answered, and laughed aloud: "Now, that is not wisely asked; has it not been told thee, that the gods made a bridge from earth to heaven, called Bifröst? Thou must have seen it; it may be that ye call it 'rainbow.' It is of three colors, and very strong, and made with cunning and with more magic art than other works of craftsmanship. But strong as it is, yet must it be broken, when the sons of Múspell shall go forth harrying and ride it, and swim their horses over great rivers; thus they shall proceed."
- Then said Gangleri: "To my thinking the gods did not build the bridge honestly, seeing that it could be broken, and they able to make it as they would."
- Then Hárr replied : "The gods are not deserving of reproof because of this work of skill: a good bridge is Bifröst, but nothing in this world is of such nature that it may be relied on when the sons of Múspell go a-harrying." -
