Driving out of my development this morning, I came to a stop sign and when I looked to my right, saw this huge arching rainbow. It looks like it is stemming from a lake, less than a mile from my house. Driving to work, which is about a mile and a half from another lake, I found the other half of the rainbow stemming from that lake.
Rainbows appear in many mythologies across space and time. Generally, they are seen as amiable, a sign from a deity. In Norse myths, the Bifrost Bridge is the connection between Asgard and Midgard, patrolled by Heimdall. Likewise, in Greco-Roman mythology it is a path made by Iris between Earth and Heaven.
In Chinese mythology, the rainbow was a slit in the sky sealed by goddess Nüwa using stones of five different colours.
In Hindu religion, the rainbow is called Indradhanush, meaning “the bow of Indra, the god of lightning, thunder and rain”. Another Indian mythology says the rainbow is the bow of Rama, the incarnation of Vishnu. Likewise, in mythology of Arabian Peninsula, the rainbow, called Qaus Quzaħ in Arabic, is the war bow of the god Quzaħ.
In Armenian mythology the rainbow is a belt of Tir, a Sun god.
Celtic lore gives us the leprechaun’s secret hiding place for his pot of gold: usually at the end of the rainbow. This place is ultimately impossible to reach.
The god from Abrahamic myths put a rainbow in the sky after he drowned the world in an apocalyptic flood as his promise to Noah to never again destroy the earth with water.
In the Dreamtime of Australian Aboriginal mythology, the rainbow snake is the deity governing water.
Some cultures see rainbows as malicious omens. In Amazonian cultures, rainbows have long been associated with malign spirits that cause harm, such as miscarriages.
Thanks to Wikipedia for helping me with some of the research.
