What's the importance and meaning of Light in the works of Pink Floyd?
Symbolically, the notion of light is associated to intelligence, illumination, the day, birth & life, while darkness is related to ignorance, fear, the night and death. Light and Darkness are also the archetypal symbols for the Solstices.
The Pulse CD shows a composition of objects which could all be related to the symbolism of light as life, intelligence and knowledge.
On the Pulse booklet front page, a man (icarus?) is crucified or suspended by rays of light. On the back cover, an object that looks like a microscope is emitting light.
The images inside the PULSE CD booklet are taken from the lightshow. Why such an emphasis on the light ?
Delicate Sound of Thunder is also related to light, with the man wearing the light bulbs.
The Dark Side of The Moon "prism" is used to decompose light.
