Claudius Ptolemy made significant contributions to astronomy with his geocentric model of the universe, the development of trigonometry, and his cataloging of over a thousand stars.
Ptolemy's "Almagest" is a seminal work in the history of astronomy, presenting his geocentric model and providing a comprehensive overview of observational astronomy.
Ptolemy's geocentric model, with Earth at the center of the universe, was widely accepted for over a millennium and influenced astronomical thought until the heliocentric model was proposed by Copernicus.
Ptolemy used a combination of naked-eye observations and complex mathematical calculations to map the positions of celestial bodies and develop his geocentric model.
