This study by the Viennese psychologist Herbert Silberer (1882-1923) was the first to link psychology with alchemical mysticism and symbolism and predates the work of Jung, who belatedly acknowledged Silberer in 1944. The book analyses a medieval alchemical 'Parable' by psychoanalysis, then from the viewpoint of alchemy and hermetic philosophy; and in synthesis offers new principles of myth interpretation. Translation, 1917.
