Hermes

Greek God. Second son of Zeus. His mother was the goddess Maia. Hermes was the god of commerce, and traveling. He was the 'Giver of good things.' Hermes also is the god of knowledge, communication, teaching and of medicine. (He was patron of both healers and teachers). His main role however was as herald of Zeus, as Messenger of the Gods.
His attributes are a winged helmet, winged feet, and the caduceus: the staff with snake(s) that still is the symbol for medicine. (According to the myth, Hermes used his staff to separate two fighting snakes. Hence the staff is also a symbol of peace.)
