Being the herald (messenger of the gods), it was his duty to guide the souls of the dead down to the underworld, which is known as a psychopomp. He was also closely connected with bringing dreams to mortals. Hermes is usually depicted with a broad-brimmed hat or a winged cap, winged sandals and the heralds staff (kerykeion in Greek, or Caduceus in Latin). It was often shown as a shaft with two white ribbons, although later they were represented by serpents intertwined in a figure of eight shape, and the shaft often had wings attached. The clothes he donned were usually that of a traveler, or that of a workman or shepherd. Other symbols of Hermes are the cock, tortoise and purse or pouch.
