Although the basic tenets of Greek geocentrism were established by the time of
Aristotle, the details of his system did not become standard. This honor was
reserved for the Ptolemaic system, espoused by the Hellenistic astronomer Claudius Ptolemaeus in the 2nd century AD. His main
astronomical book, the Almagest, was the culmination of centuries of work
by Hellenic, Hellenistic and Babylonian
astronomers; it was accepted for over a millennium as the correct cosmological
model by European and Islamic astronomers. Because of its
influence, the Ptolemaic system is sometimes considered identical with the
geocentric model.
