The concept of this noosphere represents the universal cycle of the Ages of Gold, Silver, Bronze, and Iron.
These four Ages are symbolized by a flow of golden continents on a silver sea (top half), and a sea of bronze with black/burnt sienna continents (bottom half).
A thin fluorescent line circles the center between green and blue stripes expressing nature and water. On the very top, like a black hole containing all its energy, a purple ring, color of the Spirit, surrounds a symbolic pressure valve. To complete this work, a red circle on the top shows the vital fire within.
