Ptolemy's Almagest is a 2nd century AD Ancient Greek mathematical and astronomical treatise on the complex motions of the stars and planetary paths. It is one of the most influential scientific texts of all time, with its geocentric model accepted as dogma for more than twelve hundred years from its origin in Hellenistic Alexandria, in the Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus.
