The Catholic Church promoted his work, which included the only mathematically sound geocentric model of the Solar System. Unlike that of most Greek mathematicians, Ptolemy's writings (foremost the Almagest) were copied or evaluated in late antiquity and into 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 is now seen as a very complex theoretical model built in order to explain a false tenet based on faith.
