Well, in a nutshell, Kepler (1571-1630) thought that the distances between
the (known) planets in the solar system where controlled by mutually
harmonic values, which is about right too. He used the platonic objects to
visualise those distances, from inside to outside: octahedron, isocahedron,
dodecahedron, tetrahedron, cube. The vortices of those objects were touching
the spheres corresponding to the orbits of the planets.
