Abstract

Various tests are applied to Claudius Ptolemy's long-suspect claim that he himself observed the more than 1000 objects in the Ancient Star Catalog. An obvious consequence of observing under the influence of Ptolemy's large equinoxposition error is found not to exist in the Catalog. The true observer's latitude, rough epoch, and probable identity are discovered. Hitherto-lost details of his fundamental work are reconstructed, including the earliest known accurate observation of the obliquity (135 B.C.).
