There is a legend surrounding the birth of Asklepios. According to some ancient sources, Apollo's twin sister Artemis caught the pregnant Coronis having an affair with another man. Artemis punished the betrayal of her brother by killing the woman, but either Hermes or Apollo rescued the unborn child. As an infant, Asklepios was sent to live with the wise centaur Chiron, and in time it was Chiron who taught Asklepios the art of medicine and healing.
Asklepios was married to a woman named Epione, and by her had a pair of sons named Machaon and Podalirius (who, incidentally, were both depicted as physicians in the Iliad of Homer). The god also had a daughter - Hygeia, the goddess who personified health. In mythology and art, Asklepios was symbolized by the snake, and indeed, this creature was commonly associated with the god in cult and ritual. It was also believed that Asklepios took the shape of a snake on occasion.
Although Asklepios was a god, there is a tradition in myth that he died. For it was believed that the god of healing dared to use his powers to bring a human back to life. Zeus, the ruler of the Greek gods, reacted to this action by striking Asklepios with a thunderbolt.
Asklepios was known as Aesculapius in Roman mythology.
