Caduceus Tattoo Meaning
The messenger, commerce, safe passage, and the staff that crosses every boundary.
The caduceus is the winged staff entwined with two serpents — the herald's wand of Hermes and Mercury, the emblem of the divine messenger, of commerce and safe passage, and of the authority to cross every boundary, the badge that made its bearer inviolable in transit between all worlds. To carry the caduceus is to carry the messenger, commerce, and safe passage — the herald's staff that crosses every boundary, the emblem of the divine messenger and of trade and diplomacy, the wand whose bearer is granted safe passage between all worlds.
The caduceus was the kerykeion — the herald's staff — of Hermes, the messenger of the gods, and it was the symbol and badge of his function as the divine messenger and herald. The staff identified Hermes (and any herald who carried such a wand) as a messenger, and in that role as inviolable in transit: a herald bearing the kerykeion was protected and not to be harmed, for the message and the messenger were sacred and under divine protection. To carry the herald's staff was to be marked as one who must be allowed to pass and speak safely.
The kerykeion thus protected the message and the messenger equally — it was the emblem of the sacred, inviolable status of the herald, the guarantee of safe passage and protection that allowed messages to be carried between parties, even between enemies, even between worlds. As the staff of Hermes, it embodied his role as the divine communicator and the one who moves safely between all realms, his authority and inviolability inscribed in the wand he bore. The Greek caduceus is the kerykeion, the herald's staff of Hermes that made the messenger inviolable. The Greek caduceus is the herald's wand of Hermes — the kerykeion, the staff and badge of Hermes's function as the divine messenger, which identified him (and any herald who bore such a wand) as a messenger inviolable in transit, protected and not to be harmed, the emblem of the sacred, inviolable status of the herald that protected message and messenger equally and guaranteed safe passage to carry messages between parties, even between enemies and between worlds.
The caduceus is frequently confused with the rod of Asclepius — the medical symbol, which has a single serpent and no wings. The US Army Medical Corps adopted the caduceus in 1902 by error; most international medical organizations correctly use the rod of Asclepius. The caduceus belongs to Hermes/Mercury, the god of messengers, thieves, travelers, and commerce — not to medicine. The two serpents are said to have wound around Hermes's staff after he used it to separate two fighting snakes, which then became the symbol of peace between opponents. The wings represent speed of transmission. The caduceus was the symbol of heralds in ancient Greece — those who carried it were under divine protection and could not be harmed; harming a herald bearing a caduceus was an offense against the gods. This is why the caduceus is also the symbol of diplomacy and of the press in some traditions.
