Great Books of the Western World - Ptolemy's Almagest, Copernicus and Kepler (1952)

The Almagest is a 2nd-century mathematical and astronomical treatise on the apparent motions of stars and planetary paths, written by Claudius Ptolemy in Koine Greek. It canonized a geocentric model of the Universe that was accepted for more than 1,200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus. It served as the basic guide for astronomers until about the beginning of the 17th century. Its original name was Mathematike Syntaxis ("The Mathematical Arrangement").
