Herbert Silberer's Hidden Symbolism of Alchemy and the Occult Arts (1917) explores the deeper meanings behind alchemical texts, Rosicrucian allegories, and mystical traditions, arguing that these works are not simply about chemical experiments but are symbolic accounts of inner transformation. Using both Freudian psychoanalysis and spiritual interpretation, Silberer demonstrates how myths, dreams, and esoteric emblems express unconscious drives as well as higher religious aspirations. He presents an old alchemical parable as a case study, then analyzes it through multiple layers—psychological, mystical, and natural-philosophical—before synthesizing these perspectives into a vision of regeneration, introversion, and the ultimate goal of union with the divine.
