Figures 1a, b, & c are examples of, respectively, (a) a Ptolemaic sphere (each Ptolemaic sphere looks like a 45rpm record carrying a circle: the complete Ptolemaic system consists of six such spheres, nested one inside the other); (b) Copernicus' diagram of his heliocentric system; and (c) Tycho's diagram, which looks Copernican but with a path marked for the sun around the Earth & no path for Earth around the sun.


 


Fig 2 is Kepler's diagram of what he called the "pretzel=shaped" orbits of geocentric planets.





Figs 3a & b are the cutout & template obtained by separating Tycho's diagram (Fig. 1b) into a part containing everything that shares in the annual rotation (Fig. 3a) and the balance, which provides the background for that annual motion. [note: "artwork" is really "cutout", which are hard to distinguish given my handwriting]
