We provide a historical perspective on the rainbow, with a review of early research and observations regarding the rainbow's origin and a discussion of some of the major contributors to our current understanding of what the rainbow represents. An overview of the various types of rainbows is undertaken. We conclude with a discussion of the rainbow's link to refraction, light, the visual system, and perception.
