The discovery of this 14th Century manuscript along with a unique image enables us to have a new understanding of the tremendous vision of Mohammed Ibn Umail, often referred to in Latin Alchemy as "Senior". Ibn Umail devoted himself to this vision for many years, which led him to deep insights into the polarity of the possibilities of the human psyche. In Aurora Consurgens, Senior is frequently quoted, which inspired Marie-Louise von Franz to study Arabic Alchemy.
