Sun-worshipping cults were important in ancient times, and religious historians of the 19th century would still attribute great importance to them, to the point of seeking to explain all the antique divinities as metaphors for the sun. Also, humans very rapidly attempted to explain manifestations of light, revealed in particular by the practice of astronomy, by submitting diverse theories which found their expression not only in cosmology but also in physics and in innumerable related applications. Finally, we can observe that light which is artificially produced or controlled, be it visible light or invisible electromagnetic radiation, is one of the essential components of a huge number of technologies today.
• In parallel with these scientific developments, European thinkers of the 17th Century drew upon light as a metaphor to define an intellectual process whose objective was to illuminate the spirit (Light, Enlightenment, Aufklârung), while artistic endeavours had always applied the idea of light and darkness in the representation or transfiguration of reality.
