Hermes is an Olympian deity in ancient Greek religion and mythology. Hermes is considered the herald of the gods. He is also considered the protector of human heralds, travellers, thieves, merchants, and orators. He is able to move quickly and freely between the worlds of the mortal and the divine, aided by his winged sandals. Hermes plays the role of the psychopomp or "soul guide" — a conductor of souls into the afterlife. In myth, Hermes functioned as the emissary and messenger of the gods, and was often presented as the son of Zeus and Maia, the Pleiad. He is regarded as "the divine trickster", for which Homer offers the most popular account in his Hymn to Hermes.
