Staff carried by Hermes as a symbol of peace. It served as a badge of protection for ancient Greek and Roman heralds and ambassadors. It was originally depicted as a rod or olive branch ending in two shoots and decorated with garlands or ribbons; in later iconography the garlands became two snakes and a pair of wings was attached to the staff to represent Hermes' speed. The caduceus was adopted as a symbol of physicians because of its similarity to the staff of Asclepius. Email this encyclopedia entry to a friend

 

Hermes' symbol of office as divine messenger was his staff, or caduceus. This was originally a willow wand with entwined ribbons, traditional badge of the herald. But the ribbons were eventually depicted as snakes. To support this mythologically, a story evolved that Hermes used the caduceus to separate two fighting snakes which forthwith twined themselves together in peace. It was Hermes' job to convey dead souls to the Underworld. And as patron of travelers, he was often shown in a wide-brimmed sun hat of straw. Hermes was known to the Romans as Mercury. His most famous depiction, a statue by Bellini, shows him alight on one foot, wings at his heels, the snaky caduceus in hand and, on his head, a rather stylized combination helmet-of-darkness and sun hat.
