Theoria Planetarum Primariorum.

Affascinate tavola che illustra i moti planetari secondo le teorie di Keplero e Copernico, che condividevano la teoria eliocentriche. A differenza di Copernico, che credeva che i pianeti avevano orbite circolari, Keplero teorizzò orbite ellittiche e una forte relazione tra geometria e cosmologia. Diverse note circondano le illustrazioni e spiegano le teorie di Keplero, così come quelle di Ismael Bullialdus, Seth Ward, e Nicolaus Mercator. Incisione in rame, coloritura coeva, in ottime condizioni. Fascinating plate showing the planetary motions according to Copernicus and Kepler, who both shared heliocentric theories of the solar system. Unlike Copernicus, who believed that the planets had circular orbits, Kepler theorized that the planets had elliptical orbits. Kepler also theorized that there was a strong relationship between geometry and cosmology. Notes surrounding the diagrams explain Kepler's theories, as well as those of Ismael Bullialdus, Seth Ward, and Nicolaus Mercator. Copper engraving, contemporary colors, in good condition. Cfr.
