In Greek mythology, Medusa was one of the three Gorgons: terrifying female creatures with live snakes for hair and the ability to turn anyone who looked at them to stone.

Perseus cut off her head and used it to petrify a violent and unwelcome suitor of his mother.  He then gave the head to the goddess Athena.
