mercury: [14] The Roman god Mercury got his name from his original role as patron of trade and tradesmen: Latin Mercurius was a derivative of merx ‘goods for sale’ (source of English commerce and merchant). The inspiration for the medieval application of the term to the fluid metal was its use as a planet-name, which dates from the classical Latin period. => commerce, merchant
Mercury
"the Roman god Mercury," mid-12c., from Latin Mercurius "Mercury," originally a god of tradesmen and thieves, from merx "merchandise" (see market (n.)); or perhaps [Klein, Tucker] from Etruscan and influenced by merx. Later he was associated with Greek Hermes. The planet closest to the sun so called in classical Latin (late 14c. in English). A hypothetical inhabitant of the planet was a Mercurean (1855) or a Mercurian (1868). For the metallic element, see mercury.
mercury (n.)
silver-white fluid metallic element, late 14c., from Medieval Latin mercurius, from Latin Mercurius (see Mercury). Prepared from cinnabar, it was one of the seven metals (bodies terrestrial) known to the ancients, which were coupled in astrology and alchemy with the seven known heavenly bodies. This one probably so associated for its mobility. The others were Sun/gold, Moon/silver, Mars/iron, Saturn/lead, Jupiter/tin, Venus/copper. The Greek name for it was hydrargyros "liquid silver," which gives the element its symbol, Hg. Compare quicksilver.
