C. Ptolemy

The eminent scholar Claudius Ptolemaeus lived between approximately 83 and 161 AD and is generally known in English as `Ptolemy`. A Greek mathematician, astrologer, astronomer and geographer, Ptolemy was probably born in a town called Ptolemais of Hermias in Roman Egypt. He died in Alexandria. Ptolemy was the author of a number of scientific treatises, of which the most important two were his work on astronomy, now known as the `Almagest`, and his introduction to the geographical knowledge of the Greco-Roman world, the `Geographia`. He also produced an interesting treatise on astrology known as the `Tetrabiblos` (`Four Books`)
