Rainbows in mythology

The rainbow has been a favorite component of mythology throughout history among many cultures around the world.

Abrahamic traditions see it as a covenant with God to preserve the world from a second flood.

Whether as a bridge to the heavens, messenger, archer's bow, or serpent, the rainbow has served as a symbol for millennia.

There are myriad beliefs in a complex diversity with several repeated themes.
