Ptolemaeus, of Greek-Egyptian heritage, was one of the most influential ancient astronomers. He is famous for his mathematics and geography and his earth-centred cosmology.
His cosmological theory (hypothesis) that the earth was the centre of the universe was held for 1,400 years; until it was refuted by Nicolas Copernicus (1473- 1543) in 1530. When Copernicus wrote De Revolutionibus Orbium Coelestium, On the Revolutions of the Celestial Spheres, in which he argued that the earth, in fact, rotated around the sun. The theory was published in 1543, the year of his death.
