A physician examines the lives of prominent historical and literary figures through a medical lens, presenting case studies that reconstruct probable illnesses, disabilities, and bodily influences on behavior and decision-making. Essays range from Tudor court scandals and medieval saints to emperors, rebels, writers, and soldiers, pairing biographical narrative with clinical interpretation to argue how syphilis, arteriosclerosis, mental disturbance, and other conditions shaped public actions. The collection balances historical research with diagnostic speculation, treats fictional characters as revealing psychological realities, and concludes with broader reflections on death and the physician’s role in interpreting past lives.
