In this work of outstanding scholarship, Singer has compiled in one volume his translated versions of Galen's medical, philosophical, and autobiographical writings, originally written in Greek. Singer collates these writings of Galen with a very useful, erudite introduction and explanatory notes throughout the text. Particularly useful for the reader is the index of brief descriptions of people mentioned in the text. The bibliography will be useful to researchers in the field, and its index is comprehensive. Singer is to be congratulated on this magisterial scholarly volume about one of the most important medical figures of the last millennium.
