He did this by use of stades, using a particular measuring system, which was remarkably accurate. The accuracy of the measurements was based on the assumptions that the earth is a sphere, Alexandria and Syene (places involved in the model) lied on the same meridian with a distance of 5000 stades apart. These assumptions give a significant deviation of 0.16ï ¼â€¦from the accurate measurements ( Kerrod, pg. 76). The Ptolemaic model explains the earth as the center of the universe.
