Ptolemy
Ptolemy( Claudius Ptolemaeus) (2nd century
AD)Egyptianastronomer and geographer. He produced the
Almagest, a compendium of contemporary astronomical knowledge, drawing on writers, such as Plato and
Hipparchus, whose works were kept in the great library at Alexandria. His
Ptolemaic system was a geocentric model of the Universe. Highly contrived as it now appears, it accounted for the observed apparent motions of the planets reasonably well, and remained largely unquestioned until the 16th century, when it was challenged by N.
Copernicus. Ptolemy's
Geography enjoyed a similar period of dominance (it convinced Columbus that he could sail westwards to India); his
Tetrabiblos was an astrological treatise.
