Platonic Solids

The Platonic Solids are the five shapes that define the symmetry of points in space and are named after Plato. They are the tetrahedron, cube (or hexahedron), octahedron, dodecahedron and icosahedron. These are considered ‘perfect’ shapes because they look the same from every corner point, every surface is identical, and all sides are made of the same shape.
Their striking beauty is derived from the symmetries and equalities in their relations.
The greeks associated four shapes of the Platonic solids with the four classical elements: Cube/Earth, Octahedron/Air, Icosahedron/Water; and Tetrahedron/Fire. Plato wrote that the fifth solid, the dodecahedron, “…the god used for arranging the constellations on the whole heaven.” /Universe.
