Hermes (/ˈhɜrmiːz/; Greek: Ἑρμῆς) is an Olympian god in Greek religion and mythology, son of Zeus and the Pleiad Maia. He is second youngest of the Olympian gods.
Hermes is a god of transitions and boundaries. He is quick and cunning, and moved freely between the worlds of the mortal and divine, as emissary and messenger of the gods, intercessor between mortals and the divine, and conductor of souls into the afterlife. He is protector and patron of travelers, herdsmen, thieves, orators and wit, literature and poets, athletics and sports, invention and trade. In some myths he is a trickster, and outwits other gods for his own satisfaction or the sake of humankind. His attributes and symbols include the herma, the rooster and the tortoise, purse or pouch, winged sandals, winged cap, and his main symbol is the herald's staff, the Greek kerykeion or Latin caduceus which consisted of two snakes wrapped around a winged staff.
In the Roman adaptation of the Greek pantheon (see interpretatio romana), Hermes is identified with the Roman god Mercury, who, though inherited from the Etruscans, developed many similar characteristics, such as being the patron of commerce.
