Hermes

Hermes, son of Zeus and the Pleiad Maia, was the herald of the Olympian gods. With his winged sandals he moved freely between the mortal and divine worlds, and he guided souls into the afterlife. He also protected heralds, thieves and orators.

He was the divine trickster, as the Homeric Hymn to Hermes tells. His chief symbol was the caduceus, a winged staff entwined with two snakes. The Romans identified him with Mercury, whose name comes from merx, merchandise.
