Caduceus (Hermes' staff) - used as a popular medical symbol. However Hermes had nothing to do with doctors. It was the Rod of Asclepius (who was the god of healing - see Minor God #5) that was originally used, but since the two are so alike most people get them mixed up, and since the Caduceus looks better (in my opinion), it's more widely used.
