As the title indicates, "The Key to Medicine and a Guide for Students" was an introduction to medicine, intended for students. After extolling the virtues of having a profession in general and of medicine in particular, Ibn Hindu (d. 423/1032) discusses various disciplines that a medical student should be familiar with, including a lengthy digression into philosophy and logic. He then deals with matters specifically medical, devoting separate sections to anatomy, diseases, pulse, and names of medicinal substances. The book was written in the early 11th century by a physician who was also the author of a treatise on philosophy and famous for his Arabic poetry - his anthology is said to have amounted to 15,000 couplets or more! For a medieval work, Ibn Hindu's book is refreshingly meticulous in its analysis and modern in its outlook.
