Ptolemy
![Portrait of Ptolemy by [[Justus van Gent]] and [[Pedro Berruguete]] (1476){{efn|name="portraits"|Since no contemporary depictions or descriptions of Ptolemy are known to have existed, later artists' impressions are unlikely to have reproduced his appearance accurately.}}](https://upload.wikimedia.org/wikipedia/commons/c/c9/Ptolemy_1476_with_armillary_sphere_model.jpg)
The Catholic Church promoted his work, which included the only mathematically sound geocentric model of the Solar System, and unlike most Greek mathematicians, Ptolemy's writings (foremost the ''Almagest'') never ceased to be copied or commented upon, both in late antiquity and in the Middle Ages. However, it is likely that only a few truly mastered the mathematics necessary to understand his works, as evidenced particularly by the many abridged and watered-down introductions to Ptolemy's astronomy that were popular among the Arabs and Byzantines. His work on epicycles has come to symbolize a very complex theoretical model built in order to explain a false assumption. Provided by Wikipedia
