The symbols of Hermes are perhaps the most distinctive of all the Olympians. Indeed, the messenger god has a complete set of attributes that identify him in both mythology and art. He is often depicted wearing a hat and boots, and carrying a staff.
Incidentally, my usual caveat applies - this list of the symbols of Hermes is not meant to be exhaustive. I am focusing here on some of the most common attributes of the Greek god.
Caduceus - This is sometimes translated as a herald’s staff. The staff is called a kerykeion in Greek.
The hat worn by Hermes has a specific name - the ancient Greeks called it a petasos.
