GREEK MYTHOLOGY. Hermes, the messenger god on Mount Olympus, had a magic wand called a Caduceus, which was given to him by Apollo. The Caduceus is a rod or staff framed by two intertwined snakes; at the top of the staff are two wings. The Caduceus symbolizes the spinal column, the central conduit for the Psychic Force, or nerve energy, which animates all the organs and members of the body.
