Johannes Kepler

Bavaria / Germany. 1570 - 1630

Comments : Astronomy; Neoplatonism; equates the 5 planets he knew about that circles the Sun with the 5 Platonic Solids and 4 Elements plus aether (each of the five Platonic solids could be uniquely inscribed and circumscribed by spherical orbs; nesting these solids, each encased in a sphere, within one another would produce six layers, corresponding to the six known planets—Mercury, Venus, Earth, Mars, Jupiter, and Saturn. By ordering the solids correctly—octahedron, icosahedron, dodecahedron, tetrahedron, cube—Kepler found that the spheres could be placed at intervals corresponding (within the accuracy limits of available astronomical observations) to the relative sizes of each planet’s path, assuming the planets circle the Sun. ) ; discovered important conjunctions of planets and a supernova but was cautious as others used it as a prophecy of the rise of Protestantism. Wanted to avoid the fate of his friend Giordano Bruno who was burnt at the stake 4 years before this discovery; Christoph Besold saved Kepler's mother when she was charged with Witchcraft; So it was a very real concern; ; wrote to Tycho Brahe and Galileo in code, to avoid the Inquisition;
