Definition: Roman scholar Claudius Ptolemaeus (known as Ptolemy) was an astronomer, mathematician and geographer at the Library of Alexandria. Ptolemy should not be confused with the Greek pharaohs of the same name. His three most famous works are the Almagest (on astronomy and geometry), the Tetrabiblos (on astrology), and Geography (in geographic knowledge).
