"Ptolemy's Universe" is a modern examination of the cosmological and philosophical dimensions of Ptolemy's thought as presented in his astronomical works. Claudius Ptolemy (second century AD) ranks as one of the most important figures in the history of science, especially renowned for his contribution to mathematical astronomy. Within astronomical works such as "The Mathematical Syntaxis", Ptolemy presented some of his views on natural philosophy, epistemology and ethics, and explained their pertinence to his astronomy. While much has been written about Ptolemy's mathematical work, few attempts have been made to understand his philosophical and cosmological ideas. In this book, Dr Taub shows how Ptolemy's conception of the celestial bodies as divine beings shaped his philosophical thinking, and how this in turn influenced his study of the heavens. Dr Taub's examination of the place of Ptolemy's ideas within the broader context of Greek philosophy, mathematics and culture, provides insights into the nature of Greek scientific thought.
