Professors Furley and Wilkie have provided a newly edited Greek text and a complete English translation with commentary of four of Galen's physiological treatises on respiration and the arteries. Their text is the first to make use of Arabic translations of An in arteriis and De usu pulsuum based on a Greek text that is earlier and better than the surviving tines. These translations have enabled them to make substantial improvements in the earlier editions of the treatises. Introducing the text are essays by Professors Furley and Wilkie on the history of theories of respiration and bloodflow in classical antiquity, the influence of Galen's work on Harvey, and Galen's experimentation and argument.Originally published in 1984.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.
