Mercury's staff is an iconic symbol of Roman mythology. It was believed to be a powerful tool that bestowed the messenger god with his ability to travel between the realms of the gods and mortals. Some synonyms for Mercury's staff include Caduceus, Rod of Asclepius, Hermes Wand, and Staff of Hermes. The Caduceus is often depicted as a winged staff with two snakes intertwined around it, whereas the Rod of Asclepius only has one snake wrapped around it. The Hermes Wand is a shorter version of Mercury's staff, and the Staff of Hermes is similar to the Caduceus but has only one snake and no wings. Regardless of the name or design, Mercury's staff remains a powerful symbol of communication and travel between worlds.
