Caduceus

grabcad

The caduceus is the traditional symbol of Hermes and features two snakes winding around an often winged staff. It is often mistakenly used as a symbol of medicine instead of the Rod of Asclepius, especially in the United States. The two-snake caduceus design has ancient and consistent associations with trade, eloquence, trickery, and negotiation. Tangential association of the caduceus with medicine has occurred through the ages, where it was sometimes associated with alchemy and wisdom.
