Renaissance Astronomy: From Geocentrism to Heliocentrism
Pre-Copernican Astronomy
Pre-Copernican astronomers did not attempt to explain the universe as it was. They believed its greatness and complexity were beyond human capacity. They were content to save face, as observations of planetary movements often didn’t match calculations based on Aristotle’s system. Planets appeared to follow circular orbits but sometimes deviated, seeming closer or farther from Earth. Ptolemy adapted the Aristotelian model with efferents and epicycles, increasing the celestial
