Mercury (Mercurius) was the Roman god of communication and travel, often serving as a mediator between the gods and mortals, his winged feet giving him the advantage of speed, and so was the patron of circulation in general. He was also responsible for conveying souls to the underworld.
He wore a winged helm that Vulcan, the god of forge and fire, had fashioned for him. This winged helm soon became synonymous with the messenger god. Mercury also carried the caduceus, a staff wound with serpents that was gifted to him by Apollo. Mercury was swift and clever, and his knowledge of major events often bordered on foresight.
