1 abr 100 año - Ptolemy (100-170 AD)

Descripción:

Ptolemy modified Aristotle's model. He developed a complex model based on concentric circles which was so successful in predicting future positions of the heavenly objects in their orbits around earth. As this model is the same as Aristotle's it is Geocentric.
