History behind the term 'Rainbow'

3000 BCE

Earliest recorded description

The term 'rainbow' can be traced back to ancient civilizations. The earliest recorded description of a rainbow comes from an ancient Egyptian papyrus dating back to around 3000 BCE. The Egyptians referred to the rainbow as 'the divine bow' and saw it as a manifestation of the gods' power.

350 BCE

Color analysis by Aristotle

In 350 BCE, the Greek philosopher Aristotle conducted a detailed analysis of rainbows. He observed that a rainbow is formed by the interaction of sunlight with raindrops in the air. Aristotle noted the primary colors of the rainbow and classified them as red, orange, yellow, green, blue, indigo, and violet – a classification that would endure for centuries.

1637 CE

Scientific explanation by Descartes

In 1637, French philosopher and mathematician René Descartes provided a scientific explanation for the formation of rainbows. Descartes described how light is refracted, or bent, as it passes through raindrops and is then reflected internally within the drop before being refracted again upon leaving. This explanation marked a significant advancement in understanding the physics behind rainbows.

1666 CE

Discovery of spectrum by Newton

In 1666, Sir Isaac Newton conducted experiments with prisms and discovered that white light is composed of a spectrum of colors. He passed sunlight through a prism, which caused the light to separate into its component colors, creating a beautiful spectrum. Newton's experiments confirmed Aristotle's earlier classification of the primary colors of the rainbow.

1802 CE

Term 'spectrum' introduced

In 1802, the English scientist Thomas Young introduced the term 'spectrum' to describe the range of colors seen when white light is dispersed. This term was directly linked to Newton's experiments and further solidified the understanding of rainbows and the color spectrum.

1855 CE

Rainbows and polarization

In 1855, Scottish physicist Sir David Brewster discovered that light from a rainbow is polarized. Brewster observed that the light waves oscillate in a specific plane, resulting in polarized light. This finding added another layer of complexity to the understanding of rainbows and their interaction with light.

20th Century

Symbol of diversity, peace, and LGBTQ+ pride

Throughout the 20th century, the rainbow took on various symbolic meanings. Particularly, it became a symbol of diversity, peace, and LGBTQ+ pride. The rainbow flag was created by artist and activist Gilbert Baker in 1978 for the San Francisco Gay Freedom Day Parade. Since then, the rainbow flag has become widely recognized as a symbol of the LGBTQ+ community.
