Second edition.
While the original edition (Pyrosophia, Utrecht, 1698) included only the five plates depicting the chemistry laboratory and its instrumentation, our edition is enriched with 19 additional plates—printed here for the first time—featuring 78 symbolic figures tracing the stages of the alchemical process.
As noted by Adam McLean, this suite constitutes the only early reproduction of the images from The Crowning of Nature, the renowned medieval alchemical manuscript.
It is one of the rarest works devoted to the philosopher’s stone, with the hidden meaning of its symbolic illustrations giving rise to numerous interpretations. Among them appear some of the most familiar emblems of alchemical tradition, such as the ouroboros, the green lion, and the phoenix.
This work was studied—alongside the Mutus Liber—by psychoanalyst Carl Gustav Jung in his Psychology and Alchemy (1953), where he discusses in particular the symbolic resonance of the image of the “winged dragon consuming itself within the alchemical vessel” (a figure reproduced in Jung’s book).
Through it, Jung integrates Barchusen’s iconography into his broader reflection on the alchemical transformation of the self.
