Tiresias, a prophet of Apollo, came across two copulating snakes while walking and hit them with a stick, wounding them, and kapow, Hera transformed him into a woman for displeasing her. The great goddess made him in her image as punishment and ended up with a devout priestess. Seven years later, now a married woman who had borne children, Tiresias returned to the scene of the crime. She encountered the same snakes copulating, appreciated the miracle, and Hera turned her back into a man.
