Caduceus
The caduceus (Latin: cādūceus; from Greek: κηρύκειον, kērykeion) is the staff of the messenger god Hermes in Greek mythology. It is also called the "herald's wand". The caduceus appeared as a golden staff with wings and a pair of serpents wrapped around it. It is often associated with medicine.
