This anthology investigates the intellectual breadth and clinical methodology of Galen of Pergamum, the most significant medical authority of the Graeco-Roman era. P. N. Singer, a scholar specializing in ancient medicine and philosophy, compiles a diverse selection of primary texts to illustrate Galen's multifaceted career. The book argues that Galen’s influence stems from his unique synthesis of anatomical research, logical rigor, and clinical practice, which defined medical standards for centuries. By organizing these writings thematically, the author provides a structured framework for understanding how Galen’s personal experiences as an imperial physician informed his broader theoretical contributions.

Scholars and students of medical history identify this anthology as a primary resource for accessing Galen’s complex thought in a readable format. Readers frequently note the academic density of the prose, which is balanced by the editor's clear and helpful explanatory notes.
