Mercury was alleged to be the son of Jupiter and daughter of Maia, daughter of Atlas. It is thought that he was originally an Etruscan deity who was borrowed by the Romans. They later transferred all the myths and legends of the Greek god Hermes to Mercury. One of his main characteristics was his faithful attendance to Jupiter, to whom he acted as messenger. Among other occupations he was regarded as the patron of merchants and thus denoted by the winged hat (petasus) he wore. It was said that all business negotiations should be kept hidden under the hat and that the wings signified that the bargaining should be swiftly completed, like a bird flying through the air.
