Sacred geometry: the pentagram in Raphael's Crucifixion

Sacred Geometry, the golden ratio or mean and phi point ratio The same ratio Vitruvius saw in the human body – 1 to PHI (1.618) – exists in every part of nature, from swimming fish to swirling planets. This divine ratio, or divine proportion, has been called the building block of all life.

The pentagram's lines are all related by the golden ratio. The regular pentagram, which has a regular pentagon inscribed within it, was the Pythagoreans' symbol.
