Aretaeus of Cappadocia

Aretaeus was a Greek physician, probably active in the 1st or 2nd century CE, associated with the medical traditions of his day and writing in the old Ionic dialect. He is best remembered for vivid clinical descriptions of diseases such as diabetes, epilepsy, tetanus, and pneumonia in his treatise on the causes, symptoms, and treatment of acute and chronic illnesses. His exact dates are uncertain, but he is regarded as one of the most observant medical writers of antiquity after Hippocrates.
