 | | In his work "the Timaeus" there is a mathematical construction of the elements, in which the cube, tetrahedron, octahedron, and icosahedron are given as the shapes of the atoms of earth, fire, air, and water. |
 | | In 300 B.C. Euclid, student of the school of Plato, proved in his manuscript "The Elements XII" that in 3 dimensions there are just 5 regular bodies called polyhedra with the properties of having faces made out of regular polygons all being convex. |
 | | Euclid also mentions that although the cube, the tetrahedron (called pyramid) and the dodecahedron are credited to the Pytagoreans (scholars of phytagoras), the octahedron and icosahedron are due to Theaetetus of Athens, a friend of Plato. |
