The Seven Metals: Alchemy and the Planets

[Paul Ferguson]

"Alchemy matched the seven classical planets to seven metals: Sun and gold, Moon and silver, Mercury and quicksilver, Venus and copper, Mars and iron, Jupiter and tin, Saturn and lead. The pairing expresses "as above, so below," the Hermetic idea that heaven and earth follow one pattern. It is symbolic history, not chemistry or prediction."
