Hermes was one of the messengers of the gods, the other being Iris.  Hermes also had a number of other jobs, which were god of travelers, shepherds, thieves, and merchant.  He also conducted dead souls to Hades in the Underworld.  He wore a winged cap and sandles, which enabled him to fly.  In addition, he was very clever and invented cards, card games, the lyre, and the alphabet.
