ABSTRACT
After the death of Hippocrates the Great, the science of medicine was still further perfected by his son-in-law, Polybus, one of the most renowned practitioners of the School of Cos. Galen was loud in praise of the skill and experience of Polybus, as well as of the fidelity with which he followed the precepts and conduct of his illustrious father-in-law. Little is known about him and the books that have been attributed to him— The Means of Preserving Health and The Diseases and Nature of the Sperm—are in all probability apocryphal. It is, however, likely that Polybus was the author of the book entitled De Natura Pueri, which is to be found in the Hippocratic Collection.
