This work is a sampling of the Hippocratic Corpus, a collection of ancient Greek medical works. At the beginning, and interspersed throughout, there are discussions on the philosophy of being a physician. There is a large section about how to treat limb fractures, and the section called The Nature of Man describes the physiological theories of the time. The book ends with a discussion of embryology and a brief anatomical description of the heart.
