A rainbow is created when rain is across a landscape and sunlight strikes the water at an appropriate angle relative to an observer for the colour spectrum to be revealed in that place. Light, of course as you would know, appears to be white but is really made up of a mixture of red, yellow, green, blue, violet, orange and indigo light. According to the laws of physics a rainbow will always be in front of you while your back is to the sun. No two people ever see the same rainbow as the eyes of two people cannot occupy the same place in space at the same time, each observer sees a different rainbow because the raindrops are constantly in motion so its appearance is always changing. Each time you see a rainbow it is unique to you. The legend that a pot of gold can be found at the rainbow's end originated in Silesia, a part of old Europe in an area located mostly in present day Poland with smaller parts also in the Czech Republic and Germany. It was told that angels put the gold there. The most famous of all rainbow legends is that at the end of every rainbow lays a pot of gold guarded by the mischievous mythical creature the Leprechaun. Like a parody of all materialistic pursuits you can never actually get to the end of a rainbow because it moves relative to your position, as long as the rain and sun is producing the phenomenon.
