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. He was considered the son of
Maia and
Jupiter in
Roman mythology. His name is possibly related to the Latin word
merx ("merchandise"; compare
merchant,
commerce, etc.),
mercari (
to trade), and
merces (
wages).
[citation needed] In his earliest forms, he appears to have been related to the
Etruscan deity Turms, both of which share characteristics with the
Greek god Hermes. In
Virgil's
Aeneid, Mercury reminds
Aeneas of his mission to found the city of Rome. In
Ovid's
Fasti, Mercury is assigned to escort the nymph
Larunda to the underworld. Mercury, however, fell in love with Larunda and made love to her on the way. Larunda thereby became mother to two children, referred to as the
Lares, invisible
household gods.
Mercury has influenced the name of many things in a variety of scientific fields, such as the planet
Mercury, and the element
mercury. The word
mercurialis commonly used to refer to something or someone erratic, volatile or unstable, derived from Mercury's swift flights from place to place. He is often depicted holding the
caduceus in his left hand.
