In Greek mythology, Hermes was traditionally shown carrying the caduceus as herald of the Olympian gods.
The caduceus was a staff entwined by two snakes and commonly topped with wings. It represented Hermes's role as messenger, herald, and guide between different realms. The staff was also connected with negotiation, commerce, and safe passage.
The caduceus is frequently confused with the Rod of Asclepius, which has one snake and is the traditional symbol of medicine. The two objects have different mythological associations: the caduceus belongs to Hermes, while the Rod of Asclepius belongs to the god of healing.
Hermes's attributes also included winged sandals and a winged cap. In Greek art, these objects helped identify him quickly, especially in scenes showing the gods' movements or messages.
