The Bifrost - the Rainbow Bridge to Asgard
The bridge between worlds
The Bifrost is a magical rainbow bridge connecting Asgard, the realm of the Aesir clan of gods, with Midgard, the world of men and is guarded by the all-seeing god Heimdall. It is thought that the word bifrost translates to mean “the shaking or trembling rainbow” alluding to the delicate nature of the bridge, just like a real rainbow. During the Viking age, it was believed that the shape of the Milky Way against the clear dark sky was a symbol of the bifrost.
Legend prophesises that during Ragnarok, the giants of Jotunheim will slip past Heimdall’s gaze and commence their assault on Asgard. This prompts Odin and almost all of the Aesir and Vanir gods along with the Valkyries and spirits of the fallen warriors who live in Asgard to ride across the Bifrost back to Midgard where the final battle will be fought. The bridge is destroyed by the giants as they advance towards earth, which is destroyed along with Asgard and the rest of the cosmos but will eventually rise from the sea and begin anew.
