Ptolemy (Claudius Ptolemaeus) – (2nd century AD) – Egyptian astronomer
Ptolemy was a celebrated geographer and astronomer who lectured at the university of Alexandria. He suggested that the sun and the planets of our solar system moved round the earth in an ellipse. This was accepted for centuries, until Copernicus (p. 122) disproved it in the 16th century. He also wrote a Geography, which gave precise details of the earth, guessed at its size, pin-pointed many important features and places, and suggested lines of longitude and latitude.
