Hippocrates, the celebrated Greek physician, was a contemporaryof the historian Herodotus. He was born in the island of Cosbetween 470 and 460 B. C., and belonged to the family thatclaimed descent from the mythical AEsculapius, son of Apollo.There was already a long medical tradition in Greece before hisday, and this he is supposed to have inherited chiefly throughhis predecessor Herodicus; and he enlarged his education byextensive travel.

One saying occurring in the words of Hippocrates has achieveduniversal currency, though few who quote it to-day are aware thatit originally referred to the art of the physician.

I swear by Apollo the physician and AEsculapius, and Health, andAll-heal, and all the gods and goddesses, that, according to myability and judgment, I will keep this Oath and this stipulation—to reckon him who taught me this Art equally dear to me as myparents, to share my substance with him, and relieve hisnecessities if required; to look upon his offspring in the samefooting as my ow
