Ptolemaic cosmology. Historical diagram of the Earth-centred (geocentric) Ptolemaic cosmological model. This system is known through the Almagest of the Egyptian-Greek astronomer Ptolemy who lived in the 2nd century. This work summarized 500 years of Greek astronomy,and this model of the heavens owed much to work by Hipparchus. The Moon,the Sun and the five known planets inhabited a series of perfect,Earth-centred,rotating spheres,ending in a sphere of stars. Inaccurate predictions led to it being overthrown by the 1543 heliocentric (Sun-centred) model revived by Copernicus. Diagram published in Italy in 1653 | |
