Definition & Meaning of "caduceus"

What is the "caduceus"?

The caduceus is a staff carried by the messenger god Hermes in Greek mythology. It is typically depicted as a long staff with two snakes winding around it and often topped with wings. The caduceus symbolizes trade, negotiation, and communication, representing Hermes' role as a guide for travelers and a mediator between gods and humans. In modern times, the caduceus is sometimes mistakenly used as a symbol of medicine and healthcare, though the rod of Asclepius, which features a single snake, is the correct symbol for healing. The caduceus remains an iconic image associated with commerce and messaging.
