Note: the Caduceus (called Kerykeion in Greek) is the cane with two intertwined snakes and wings that is used as symbol of medicine in America, despite being associated with the god Hermes/Mercury and trading. This is because it is easily confused with the Rod of Asclepius, the real symbol of healing which has only one snake and no wings. Asclepius was a mythological doctor of great skill, and the Romans saw him as the man representing the Ophiuchus constellation.
