The drawing above is a representation of the Norse conception of the universe as an enormous tree around which is the Earth. At the root of the tree are the world of the Dead, that of the gods, and that of the giants.

Bifrost

Bifrost, the rainbow, was the bridge leading from the Earth, called Midgard, to Asgard, the home of the gods.

Only the gods could cross this bridge, which was guarded by the god Heimdall. This bridge has also been associated with the Milky Way.

It was said that during the very last battle between good and evil, Bifrost shattered from the weight of the monsters.
