The Greek Influence on Early Islamic Mathematical Astronomy

Abstract

Some concepts of Greek mathematical astronomy reached Islam in the eighth century through translations and adaptations of Sanskrit and Pahlavî texts. These represented largely non-Ptolemaic ideas and methods which had been altered in one way or another in accordance with the traditions of India and Iran. When to this mingling of Greco-Indian and Greco-Iranian astronomy was added the more Ptolemaic Greco-Syrian in the late eighth and early ninth centuries, and the completely Ptolemaic Byzantine tradition during the course of the ninth, the attention of Islamic astronomers was turned to those areas where these several astronomical systems were in conflict. This led to the development in Islam of a mathematical astronomy that was essentially Ptolemaic, but in which new parameters were introduced and new solutions to problems in spherical trigonometry derived from India tended to replace those of the Almagest.
