Ptolemy further developed the geocentric model by introducing the concept of epicycles, which explained the complex movements of planets as they traveled in small circles (epicycles) while orbiting the Earth in larger circles (deferents). This allowed for a more accurate prediction of planetary positions, accommodating observed retrograde motion. His work, particularly in the "Almagest," synthesized earlier astronomical knowledge and provided a comprehensive framework that dominated Western astronomy for over a millennium.
