This black-and-white line illustration depicts the caduceus, a symbol featuring two intertwined snakes ascending a winged staff topped with a sphere. Though commonly mistaken for the Rod of Asclepius (a single snake on a staff), the caduceus originates from ancient Greek mythology as the herald’s staff of Hermes, associated with trade, negotiation, and travel-not healing. Its adoption by U.S. medical services in the 20th century cemented its modern association with healthcare despite historical inaccuracies.
