Rainbows in culture

The rainbow has been a favorite component of art and religion throughout history.

The rainbow has found a place in the mythological systems of many cultures. It is sometimes personified as a deity, such as the Greco-Roman messenger goddess Iris, or the Aboriginal Australian Rainbow Serpent.

In Albanian folk beliefs the rainbow is regarded as the belt of the goddess Prende, and oral legend has it that anyone who jumps over the rainbow changes their sex.^[1]

In other cultures it may represent a bridge or an archer's bow. In Judaism and Christianity, the rainbow is associated with God's protection, as it is described in the Book of Genesis (9:11–17) as a sign of the covenant between God and man.

Rainbows are generally described as very colourful and peaceful. The rainbow occurs often in paintings.^[2] Frequently these have a symbolic or programmatic significance (for example, Albrecht Dürer's Melancholia I). In particular, the rainbow appears regularly in religious art (for example, Joseph Anton Koch's Noah's Thank Offering). Romantic landscape painters such as J. M. W. Turner and John Constable were more concerned with recording fleeting effects of light (for example, Constable's Salisbury Cathedral from the Meadows). Other notable examples appear in work by Hans Memling, Caspar David Friedrich, and Peter Paul Rubens.

In contemporary visual art, the rainbow often appears as well, notably in Peter Coffin's Untitled (Rainbow), 2005,^[3] and in Ugo Rondinone's Hell, Yes!, 2001.^[4] Like many other cultural references to the rainbow, these either emphasize the possible sublimity of the natural world or the cheerfulness, joy, and celebration often culturally associated with a profusion of colors.

In 2012, American artist, Michael Jones McKean created a large-scale artwork, The Rainbow.^[5] The project created, impart, a fully sustainable prismatic rainbow using thousands of gallons of pressurized harvested rainwater, at times stretching several city blocks in size.^[6]

In heraldry the rainbow proper consists of 4 bands of colour (Or, Gules, Vert, Argent) with the ends resting on clouds.^[7] Generalised examples in coat of arms include those of the towns of Regen and Pfreimd, both in Bavaria, Germany; of Bouffémont, France; and of the 69th Infantry Regiment (New York) of the United States Army National Guard.

The rainbow inspires metaphor and simile. Virginia Woolf in To the Lighthouse highlights the transience of life and Man's mortality through Mrs Ramsey's thought: "it was all as ephemeral as a rainbow".

Wordsworth's 1802 poem "My Heart Leaps Up" begins:

My heart leaps up when I behold
A rainbow in the sky:
So was it when my life began;
So is it now I am a man;
So be it when I shall grow old,
Or let me die!...

The Newtonian deconstruction of the rainbow is said to have provoked John Keats to lament in his 1820 poem "Lamia":

Do not all charms fly
At the mere touch of cold philosophy?
There was an awful rainbow once in heaven:
We know her woof, her texture; she is given
In the dull catalogue of common things.
Philosophy will clip an Angel's wings,
Conquer all mysteries by rule and line,
Empty the haunted air, and gnomed mine –
Unweave a rainbow

In contrast to this is Richard Dawkins; talking about his 1998 book Unweaving the Rainbow: Science, Delusion and the Appetite for Wonder, wrote:

My title is from Keats, who believed that Newton had destroyed all the poetry of the rainbow by reducing it to the prismatic colours. Keats could hardly have been more wrong, and my aim is to guide all who are tempted by a similar view, towards the opposite conclusion. Science is, or ought to be, the inspiration for great poetry.

Rainbow flags tend to be used as a sign of a new era, of hope, or of social change. Rainbow flags have been used in many places over the centuries: in the German Peasants' War in the 16th century, as a symbol of the Cooperative movement; as a symbol of peace, especially in Italy; to represent the Tawantin Suyu, or Inca territory, mainly in Peru and Bolivia;^[8] by some Druze communities in the Middle east; by the Jewish Autonomous Oblast; to represent the International Order of the Rainbow for Girls since the early 1920s, and as a modified symbol of gay pride and LGBT social movements since the 1970s.^[9][10] In the 1990s, Archbishop Desmond Tutu and President Nelson Mandela described the newly democratic South Africa as the "rainbow nation", also alluding to its diversity and multiculturalism.
