The green gold is the living quality which the alchemists saw not only in man but also in inorganic nature. It is an expression of the life-spirit, the anima mundi... Mercurius is... extolled by the masters of the art as 'benedicta viriditas — blessed greenness.'
Von Franz establishes green as the alchemical color of the anima mundi and Mercurius, a cosmic life-force breathed into all created things and identified with 'blessed greenness.'
