Caduceus Medical Symbol - History, Meaning, and Modern Use #2007621 (License: Personal Use)

This black-and-white illustration depicts the Caduceus, a classical symbol featuring a winged staff with two serpents coiled symmetrically around it and a sphere at the top. Though commonly associated with medicine today, the Caduceus originally represented Hermes (Mercury), the Greek messenger god of commerce, negotiation, and travel-not healing. Its adoption by U.S. military medicine in the 19th century cemented its modern misassociation with healthcare, despite the Rod of Asclepius being the historically accurate medical symbol.

Used on hospital signage, medical websites, pharmaceutical branding, and educational content to denote healthcare services; often appears in contexts where symbolic authority or professionalism is emphasized, though frequently confused with the true medical symbol.
