​Meaning:Ornamented rod or staff borne by rulers on ceremonial occasions as an emblem of authority and sovereignty. The primeval symbol of the staff was familiar to the Greeks and Romans and to the Germanic tribes in various forms (baculus, "long staff"; sceptrum, "short staff") and had various significances. The staff of command belonged to God as well as to the earthly ruler; there were the old man's staff, the messenger's wand, the shepherd's crook, and, derived from it, the bishop's, and so on.
