Mercury is indicated as “spirit”, substance for the alchemists and “Stone”. It is therefore that god imprisoned in matter that ultimately must be freed. And for this reason it is identical to Lapis, the “stone of the wise” or blessed, immortal medicine of which C. G. Jung, the father of analytical psychology, provides more than one “vivifying” image throughout his opus alchymicum. According to Jung, Mercury is ultimately the collective unconscious itself in its unlimited qualifications. In the present volume the author moves in a tangle of analogies and metaphors mentioning ancient and Latin texts referring to Jungian literature in a complex network of synonyms designed to represent Mercury itself, an exceptional parallel of the “psychic substance” to which Jung gave credit for the subject of branching out into a vast psychological problem.
