(circa 90-circa 168)
Born in Egypt
Lived in Alexandria
Believed to be either a Greek or a Hellenized Egyptian
Wrote 'The Almagest' on astronomy, 'Geographia,' and 'Tetrabiblios' on astrology
Why he might be annoying
Medieval translations of his works often referred to him as 'Ptolemy, King of Alexandria,' apparently mistaking him for one of the Ptolemies who ruled Egypt between Alexander the Great and the Romans.
His 'Almagest' popularized the geocentric (earth-centered) view of the universe.
The tables of locations in his 'Geographia' include numerous errors. (Although some of these, such as the southernmost point of Malaysia being moved south of the equator, were mistakes made by scribes copying his works.)
Why he might not be annoying
His 'Almagest' is the most comprehensive source of information about ancient Greek astronomy.
'Geographia' was consulted by Columbus, Da Gama, Magellan and other Renaissance explorers during their travels.
He had craters on the Moon and Mars and an asteroid named after him.
