Copernicus and his Islamic Predecessors: Some Historical Remarks

Abstract

Based upon research over the past half century, there has been a growing recognition that a number of mathematical models used by Copernicus had originally been developed by Islamic astronomers. This has led to speculation about how Copernicus may have learned of these models and the role they played in the development of his revolutionary, heliocentric cosmology. Most discussion of this connection has thus far been confined to fairly technical issues related to these models; recently, though, it has been argued that the connections may go deeper, extending into the physics of a moving Earth and the way in which astronomy itself was conceived. The purpose of this article is to give an overview of these possible connections between Copernicus and his Islamic predecessors and to discuss some of their implications for Copernican studies.
