Ptolemy

Ptolemy was the author of the Treatise on the Structure, Position and Medicinal Nature of Celestial Bodies. The Fourth Doctor checked it out from the Library of Alexandria. At one point in his travels with Leela he reckoned that it was overdue by 2093 years and four months. (PROSE: Eye of Heaven)
According to the First Doctor, Ptolemy "proved" that the sun and the planets orbited the Earth. (AUDIO: The Library of Alexandria)
