All 5 of the Platonic solids can be geometrically drawn this way, but here I made only one of them. The ancient Greek philosopher Plato c. 360 B.C. theorised that the classical elements of the world were made of these regular solids. The five Platonic Solids were thought to represent the five basic elements: earth, air, fire, water, and the universe (the heavens with its 12 constellations). In particular, an icosahedron is a polyhedron with 20 faces. The name comes from Ancient Greek εἴκοσι meaning "twenty" and from Ancient Greek ἕδρα meaning "seat". Of the Platonic solids, it has the largest volume for its surface area. The icosahedron was associated with the element of water, and thus reflecting creativity, intuition, emotions.
