Claudius Ptolemaeus

Claudius Ptolemaeus, commonly known as Ptolemy, was an influential Greco-Roman scholar from the 2nd century AD, best known for his work in astronomy, geography, and mathematics. His most famous text, the "Almagest," proposed the geocentric model of the universe, which placed Earth at the center, influencing Western thought for over a thousand years. Ptolemy also created maps of the known world and developed a system for longitude and latitude. His contributions laid the groundwork for future scientific exploration, although his astronomical theories were eventually replaced by the heliocentric model proposed by Copernicus.
