Mercury, Latin: Mercurius is a major Roman god, being one of the Dii Consentes within the ancient Roman pantheon. He is the patron god of financial gain, commerce, eloquence (and thus poetry), messages/communication (including divination), travelers, boundaries, luck, trickery and thieves; he is also the guide of souls to the underworld. Mercury had essentially the same aspects as Hermes, wearing winged shoes (talaria) and a winged hat (petasos), and carrying the caduceus, a herald's staff with two entwined snakes that was Apollo's gift to Hermes.
