The Nigredo not only brought decay, suffering, death, and the torments of hell visibly before the eyes of the alchemist, it also cast the shadow of melancholy over his solitary soul. In the blackness of his despair he experienced.. grotesque images which reflect the conflict of opposites into which the researcher’s curiosity had led him. His work began with a katabasis, a journey to the underworld as Dante also experienced it.
