On the Affected Parts

On the Affected Parts is a medical text written by the Greek physician Galen in approximately 165 CE. The work spans six books and presents Galen's systematic approach to diagnosing and treating diseases based on their anatomical location. The text establishes a framework for understanding how different parts of the body interact and influence each other during illness. Galen draws on his extensive experience as a physician to document symptoms, progression of diseases, and treatment methods. Galen includes detailed case studies from his own practice to illustrate his medical theories and approaches. His observations cover conditions affecting major organ systems, the nervous system, and musculoskeletal disorders. The work represents a landmark in medical literature that helped establish the foundation for anatomically-based diagnosis in Western medicine. Its emphasis on careful observation and logical analysis of symptoms marked a shift toward more systematic medical practice.
