Myths, Symbols & Folklore
dodecahedron: It is a body bounded by 12 flat polygons. Especially significant symbolically is the pentagonal dodecahedron, which is formed of 12 equilateral pentagons; it participates in the symbolism of the number twelve and five. It was thought to be the most perfect of the five uniform, or Platonic, bodies and is consequently a totality symbol. Plato assumed that the cosmos had the form of a dodecahedron. (Herder)
