Caduceus as a symbol of medicine

The caduceus is the traditional symbol of Hermes and features two snakes winding around an often winged staff. It is often used as a symbol of medicine, especially in the United States. Ancient sources associate Hermes with a variety of attributes, including wisdom, trade, deception, thievery, eloquence, negotiation, and alchemy.

The modern use of the caduceus as a symbol of medicine became established in the United States in the late 19th and early 20th century as a result of well-documented mistakes and misunderstandings of symbology and classical culture. Critics say the correct symbol for medicine is the Rod of Asclepius, which has only one snake and no wings.
