Ptolemy’s Geography

Ptolemy’s Geography, created by the Greek scholar Claudius Ptolemy around the 2nd century AD, was an influential work that compiled and mapped the known world using coordinate systems. It used latitude and longitude to describe locations, helping scholars and explorers understand and navigate geography more systematically. The book included maps, geographic data, and methods for estimating distances and positions, laying the foundation for later cartography and navigation techniques. Despite some inaccuracies due to limited knowledge at the time, it significantly shaped geographic thought and exploration during the Middle Ages and the Renaissance.
