kerykeion

The kerykeion, also commonly spelled kerykeion or kerukeion, is a herald's staff, a symbol of the god Hermes in Greek mythology. It is typically depicted as a short staff entwined by two serpents, with or without wings at the top. While its precise origin is unclear, the kerykeion is most famously associated with Hermes, the messenger of the gods, who used it to enforce peace and protect heralds.

In ancient Greek culture, the kerykeion represented authority, protection, and safe passage. Heralds carried it as a sign of their diplomatic immunity, ensuring they could travel and deliver messages without fear of harm. The serpents intertwined around the staff are often interpreted as symbols of reconciliation, healing, or duality, reflecting Hermes' multifaceted nature as a god of commerce, thieves, and transitions.

Over time, the kerykeion evolved into a broader symbol. It was adopted by various groups and professions, eventually becoming associated with medicine. This association likely stemmed from the caduceus, a similar staff that was also associated with Hermes and later became a medical symbol, particularly in modern times. While the kerykeion and the caduceus are often conflated, the kerykeion's primary mythological role is as a herald's staff and a symbol of Hermes. Its imagery and symbolism continue to resonate in art, literature, and cultural representations.
