A dodecahedron is a Platonic solid, a regular polyhedron with twelve pentagonal faces. Five solids meet those criteria, and each is named after its number of faces. They are Platonic, because was the Greek philosopher Plato who theorized in his Timaeus, that the classical elements, Earth, Water, Wind and Fire, were made of these regular solids. Ancient and modern objects have the dodecahedral shape; a list of them  (on the left) is here collected.
