The cube represents the earth in Pythagorean, Indian and Platonic traditions. In Egypt, the Pharaoh is often depicted sitting on a cubic throne. In India, many statues of deities are shown standing on a cube – one under each foot. It is understood as a building block of all simple matter – and it is also understood that within it supernatural possibilities abound. Therefore cube represents the earth from which the spiritual king comes forth.
