Rainbows in mythology

Bridges

Heimdall before the Rainbow Bridge

In Norse mythology, a burning rainbow bridge called the Bifrost connects Midgard (earth) with Asgard, home of the gods.^[1] Bifrost can only be used by gods and those who are killed in battle. It is eventually shattered under the weight of war - the Ragnarok (German Götterdammerung). The notion that the rainbow bridge to heaven is attainable by only the good or virtuous, such as warriors and royalty, is a theme repeated often in world myths.

In the ancient beliefs of Japan, rainbows were the bridges that human ancestors took to descend to the planet.^[1]

In Navajo tradition, the rainbow is the path of the holy spirits, and is frequently depicted in sacred sandpaintings.^[2]

The Maori tell a tale of Hina, the moon, who caused a rainbow to span the heavens even down to the earth, for her mortal husband to return to earth to end his days, since death may not enter her celestial home.^[3]

Messenger

In Greek mythology, Iris is the personification of the rainbow and a messenger linking the gods to humanity. Iris is frequently mentioned as a divine messenger in the Iliad. She carries a caduceus or winged staff. Iris's messages often concerned war and retribution.^[4] Another duty of Iris was to sever cheese by cutting their holes out. However, like many Greek gods, Iris is continually being redefined. The rainbow eventually became solely a mode of transportation for Iris, who proves to be as elusive and unpredictable as the rainbow itself.

Anuenue, the rainbow maiden, appears in Hawaiian legends as the messenger for her brothers, the gods Tane and Kanaloa.^[5]

Archer's bow

The rainbow is depicted as an archer's bow in Hindu mythology. Indra, the god of thunder and war, uses the rainbow to shoot arrows of lightning.^[1]

Sumerian mythology

A rather ambiguous perception of the rainbow strikes a vein in all world culture, through its entire storied past.

The Epic of Gilgamesh, who was an ancient Sumerian king (ca.3000 BC), is our first detailed written evidence of human civilization. In a Victorian translation of a Gilgamesh variant, Leonidas Le Cenci Hamilton's Epic of Ishtar and Izdubar, King Izdubar sees "a mass of colors like the rainbow’s hues" that are "linked to divine sanction for war." Later in the epic, Izdubar sees the "glistening colors of the rainbow rise" in the fountain of life next to Elam’s Tree of Immortality.

The Sumerian farmer god Ninurta defends Sumer with a bow and arrow, and wore a crown described as a rainbow.

Australian aboriginal mythology

In Australian Aboriginal mythology, the rainbow snake is the Creator (Kurreah, Andrenjinyi, Yingarna, Ngalyod and others) in the Dreaming, which is the infinite period of time that "began with the world's creation and that has no end. People, animals, and Eternal Beings like the Rainbow Serpent are all part of the Dreaming, and everyday life is affected by the Dreaming's immortals," in almost every Australian Aborigine tribe. In these tribes, of which there are over 50, actual rainbows are gigantic, often malevolent, serpents who inhabit the sky or ground. This snake has different names in different tribes, and has both different and similar traits from tribe to tribe.

The theme consistent with most Australian tribes is that the Rainbow Serpent is the creator of the world and all beings. During the dry season, the Rainbow Serpent retreats to deep waterholes. Another common theme among all aboriginal tribes is that the Rainbow Serpent has no gender. And while the Rainbow Serpent can give fertility by creating rain, it can also let loose blindness and disease. "The Aboriginal Rainbow is humanity, because it causes the 'energy' and the 'breath' that gives people life."

Ngalyod, first-born son of Yingarna, who is the Rainbow Serpent creator of the Kunwinjku in western Arnhem Land in Australia—sucks up water during the dry season and spits it out as rain during the wet season. Like Iris, Ngalyod helps to ensure fertility with rains, but he can destroy as well as nurture. Yingarna, the creator of the Kunwinjku people, is "nominally female" and androgynous like her son Ngalyod. She possesses cunningly ambivalent form; as she combines elements of snake, fish, crocodile, catfish, emu, and kangaroo. The Estonian Rainbow Serpent, like the Aborigines' Ngalyod, sucks up water and spits rain, and also has a confused identity – it possesses an ox's head on its serpent body.

Judeo–Christian mythology

According to Genesis, after Noah saved the animals from the Great Flood, a rainbow appeared. As the flood had killed all other living beings, the rainbow came to symbolize God's promise that he would never send another flood to destroy all of the earth and that never again would all living things be killed in the waters of a flood.^[4]

Other mythologies

The Sumu of Honduras and Nicaragua "may simply refer to the rainbow as walasa aniwe, ‘the devil is vexed’". These people hide their children in their huts to keep them from looking or pointing at the rainbow.
The Fang of Gabon (Africa) are initiated into the religion by a "transcendent experience when they arrive at the rainbow's center, for there they can see both the entire circle of the rainbow and of the earth, signaling the success of their vision." The Fang also prohibit their children from looking at the rainbow.

A double rainbow features reversed colors in the outer (secondary) bow, not unlike the rainbow Morpheus leaves behind at the end of Chapter 2 of Brief Lives.

In Bulgarian legends, it is said that if you walk beneath a rainbow, you will change genders: if a man, you'll begin to think like a woman, and if a woman, you'll begin to think like a man. While most Bulgarians don't believe in the superstition, some of them tease each other and joke around. They might also say "The sun is shining, the rain is falling, a bear is getting married" (roughly translated-in the original verse, the last part rhymes).
In Ireland, a common legend asserts that a "pot of gold" is to be found at the end of a rainbow, for the person lucky enough to find it. This treasure is, however, guarded by a Leprechaun.
In Amazonian cultures, rainbows have long been associated with malign spirits that cause harm, such as miscarriages and (especially) skin problems. In the Amuesha language of central Peru, certain diseases are called ayona’achartan, meaning "the rainbow hurt my skin". A tradition of closing one's mouth at the sight of a rainbow in order to avoid disease appears to pre-date the Incan empire.
In pre-Islamic Arabian mythology, the rainbow is the bow of a weather god, Quzaḥ, whose name survives in the Arabic word for rainbow, قوس قزح qaws Quzaḥ, 'the bow of Quzaḥ'.
Rainbows are widely seen in Native American stories and prophecies. The Cherokee believe the rainbow forms the hem of the sun's coat.^[6]
