It is said that Asklepios may have once lived and been renowned for his gentle, humane remedies and his humane treatment of the mentally ill. His followers established temples called Asklepios, which were temples of healing. The most infamous asklepion was in a grove of trees south of Corinth, Greece where the ill had to stay overnight while the proper remedies were revealed during a dream to the priests of the temple and the cured had to make a suitable sacrifice (usually a rooster) to the god.
