"Rainbows the Mythology and the Magic" A rainbow can be classified as an extraordinary and attractive natural phenomenon that has fascinated humans throughout the ages. There have been numerous observations of rainbows and many different definitions passed out through the cultures. Descriptions such as " A rainbow is seven colors in the sky. It is a phenomenon which makes its appearance when it is raining at the same time when the sun is shining. " (Irwin, 32) have been transmitted verbally through cultures. There are many different aspects to a rainbow; from the technical issues such as the refraction of light, to the mythology which includes the Irish stories of leprechauns.
All of these combine to make the rainbow one of the most significantly symbolic shapes of the ages. The science behind the rainbow is very simple. A rainbow is simply an arc of concentric colored bands that develops when sunlight interacts with raindrops. Sunlight is refracted as it enters a raindrop, which causes the different wavelengths of visible light to separate.
Longer wavelengths of light such as red are bent the least while shorter wavelengths of violet and blue are bent the most. (Parkhurst, 58) Much can also be said about the angles of the sun as it hits the different raindrops. If the angle between the refracted light and the normal (which forms a perpendicular angle to the surface) if the drop of the surface is greater then the critical angle, about 48 degrees, then the light will reflect off the back of the raindrop. If the angle is smaller then 48 degrees then the light will simply pass on through. The reflected light is refracted as it exits the raindrop. This means that the light does not exit at the same angle as it entered.
Violet light, which bends the most, emerges at an angle of 40 degrees relative to the incoming sunlight while red light, which bends the least, exits the drop at an angle of 42 degrees. The other 5 colors, orange, yellow, green, blue and indigo, will leave the raindrop at angles in between. Usually, a rainbow will be seen when rain is falling in one part of the sky and the sun is shining in the other. For the rainbow to be visible, the sun must be behind the observer, who is in effect, facing the rain. Since only one color of light is observed from each raindrop, an incredible number of raindrops is required to produce the magnificent spectrum of colors that are characteristic of a rainbow. (Kemp, 102) The etymology of the word rainbow is very diverse. Its connection with rain and heaven is very apparent in almost every culture.
Balto-Finnic languages such as the Finnish, Indian and Karelian use the word sateenkaari, which places the emphasis on rain. This emphasis continues into the Germanic languages as well: German Regenbogen, Swedish reengage, Old Norse regnbogi, and Danish regnum. Also very widespread is the connection with heaven. This is apparent in the French language which uses the word arc-en-ciel. In Latin there are many different expressions denoting the rainbow: arcus plugins 'rainbow', arcus celestia 'bow of the heaven or gods', arcus colorants ' colored bow'. (Shweizer, 60) In the Bible the rainbow is referred to in both the New and Old Testaments, both in fairly similar contexts. The most well known rainbow is found in the Old Testament where the rainbow is a sign of the covenant between God and Noah.
Genesis 9: 13 reads: "I do set my bow in the cloud; and it shall be for a token of a covenant between me and the earth. " The common interpretation of this rainbow is ambiguous and denotes God's wrath and mercy. The New Testament takes a comparable approach to the rainbow when the Book of Revelations 4: 3 reads "And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight unto an emerald. " This is also a symbol of the covenant between God and his followers. However, in the Bible there is no found reference to the colors of the rainbow nor the number of them. Since the ancient Gothic times, rainbows have been depicted in art. Paintings which contain apocalyptic motifs use the rainbow as a halo surrounding the body of God or a saint. In Gothic art such as Maiestas Domini, Christ is depicted as sitting on the rainbow in the midst of the Final Judgement. (Kemp, 138) The mythology and mystery that has been designated to the rainbow in different cultures is one of the most varied in the whole world of nature.
Many natural phenomenons are characterized as symbolic, however they are usually consistent. For example, in every civilization, fire is looked on as a form of destruction. The meaning of the rainbow is incredibly diverse from culture to culture. Generally speaking it is looked at for its beauty as a source of positive emotions and a gladdening of the heart. The widespread image of the rainbow is a bow, with which God sends down arrows and rain.
But taken further, the rainbow was considered to be someone's belt or robe. In the Albanian culture the rainbow is the belt of the goddess of beauty, and a later Catholic Saint Prince (or Prince), whose name is derived from the word peretti meaning 'heaven'. Swallows were harnessed to her carriage and pulled her through the gates of heaven. (Irwin, 145) The Greek mythology also attributes the rainbow to a goddess. Iris was the daughter of Thomas and Electra, the sister of Harpies and a messenger of the gods of Olympus.
She is represented as both the goddess of the rainbow and its impersonation. The rainbow has been said to be the belt of Iris, a footpath between heaven and earth, or the stairway from which Iris descended to deliver messages to the mortals. Ironically, the original meaning of the word iris is 'path or band'. (Schweizer, 173) Some cultures have shown us that the rainbow is not as innocent and beautiful as it appears. Throughout Australia a serpent has been used as a simile of the r...
