Circles, Circles, Everywhere
If you look around, circles are all around us everywhere. Circles have also fascinated people throughout the ages. In Ancient Greek culture the circle was thought of as the perfect shape. To the Greeks the circle was a symbol of the divine symmetry and balance in nature. Greek mathematicians were fascinated by the geometry of circles and explored their properties for centuries. In Chinese philosophy, the circle of yin and yang describes how seemingly opposite or contrary forces may actually be complementary, interconnected and interdependent in the natural world, and how they may give rise to each other as they interrelate to one another. Circles are still symbolically important today -they are often used to symbolize harmony and unity. For example, the five interlocking rings of different colors for Olympic represents the five major continents of the world united together in a spirit of healthy competition.
A circle is the reflection of eternity. It has no beginning and it has no end - and if you put several circles over each other, then you get a spiral. — Maynard James Keenan
