Word Origin & History

magnesia 
c.1386, in alchemy, "main ingredient of the philosopher's stone," from M.L. magnesia, from Gk. (he) Magnesia (lithos) "the lodestone," lit. "(the) Magnesian (stone)," from Magnesia, region in Thessaly. Perhaps manganese is meant. Connection with magnet is obscure. Main modern sense of "magnesium oxide" (1755) is perhaps an independent formation from L. magnes carneus "flesh-magnet" (c.1550), so called because it adheres strongly to the lips.
