    — The association of the heavenly bodies with known metals and also with human organs and destinies goes back to ancient Chaldea, the land of astrologers. In Chaucer’s words: ‘The seven bodies eek, lo hear anon. Sol gold is, and Luna silver we declare; Mars yron, Mercurie is quyksilver; Saturnian leed; and Jubitur is tyn, and Venus coper, by my fathers kyn.’ […] Corresponding names were bestowed upon salts of these metals by the alchemists, and some of them have persisted down to the present day. Some examples are lunar caustic (silver nitrate); vitriol of Venus (copper sulphate); sugar of Saturn (lead acetate); and vitriol of Mars, or Martial vitriol (ferrous sulphate).
