Hippocrates (Gr.). A famous physician of Cos, one of the Cyclades, who flourished at Athens during the invasion of Artaxerxes, and delivered that town from a dreadful pestilence. He was called “the father of Medicine “. Having studied his art from the votive tablets offered by the cured patients at the temples of Æsculapius, he became an Initiate and the most proficient healer of his day, so much so that he was almost deified. His learning and knowledge were enormous. Galen says of his writings that they are truly the voice of an oracle. He died in his 100th year, 361 B.c.
