Hippocrates was Greek physician, who was born around 460 B.C. on the island of Kos in the Aegean Sea, to a family of doctors. Many treatises on medicine have been attributed to him. He is known for having revolutionised medicine, by the use of a pragmatic and rational method that ran counter to the religious and magical methods then in use. Hippocratic ethics are explained in a number of the treatises under his name, including today’s Hippocratic Oath. This oath was sworn by his disciples and is still repeated by future doctors today, if in a modified form. The Oath details doctors’ duties, including the privacy of the doctor-patient relationship. Hippocrates died around 370 B.C.
