Aesculapius
Main god associated with healing, prophecy, and divination.
When Aesculapius was just a fetus in the womb, his mother Coronis (no relation to Cronus found) was unfaithful to his father, Apollo. Apollo was so upset by this that he asked his sister Artemis to kill her. He saved Aesculapius by ripping him out of the womb as Cronus was cremated. Chiron, the wisest, most gentle centaur, raised Aesculapius and taught him all medicinal secrets.
Later, Aesculapius married and proceeded to live a normal family life, but Zeus killed him with a lightning bolt after he dared bring the deceased back to vitality. Apollo took revenge upon Zeus by killing his sons, the Cyclopes. Apollo was punished for one year by becoming a servant to a mortal king. Aesculapius was most likely a hero who achieved divinity. Although he was associated with prophecy and divination like his father, his best gift was medicinal treatment. He is also highly associated with serpents, usually depicted carrying one around on his staff.
