My Platonic Sweetheart was created in 1912.
Greek philosopher Plato (428-348 BC)
No, a cone is not a Platonic solid. The Platonic solids are the five regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.
The book called Platonic Solids: The experience
There are different numbers on the different platonic solids.
We don't know for certain who discovered the platonic solids first. However, Pythagoras is credited by some sources as discovering the platonic solids first. Other sources credit Theaetetus as being the first to describe all five platonic solids and proving that these are the *only* platonic solids.
