The Collected Works of Marie-Louise von Franz is a 28 volume Magnum Opus from one of the leading minds in Jungian Psychology. Volume 7 turns to Aurora Consurgens - A Document Attributed to Thomas Aquinas on the Problem of Opposites in Alchemy - A Companion Work to C.G. Jung's Mysterium Coniunctionis.
Aurora Consurgens, the rising sun, is a vision forged in the pseudo-Aristotelian tradition that became a cornerstone of medieval Church doctrine and the centerpiece of the Dominican and Franciscan traditions. While its authorship has been shrouded in mystery and controversy, Marie Louise von Franz furnishes ample evidence that this was a final work of Thomas Aquinas, a Doctor of the Church. His vision begins with an anima figure of the Sapentia Dei.
This medieval alchemical text is rich in symbolism and offers a glimpse into how unconscious contents can be understood through their interactions with the material world. Marie Louise von Franz places Aurora Consurgens squarely in the tradition of visionary spiritual writings similar to the visions of Hildegard von Bingen or John of Patmos. Aquinas's visions and his final commentary on the Song of Songs appear to have been the result of a state of ecstasy into which he fell just before his death. Marie Louise von Franz excavates a psychological treasure from his work.

At the age of eighteen, while still in high school, Marie-Louise von Franz met Carl Jung at his Bolingen Tower. She later described this as the most decisive encounter of her life. She entered analysis with him months later, completed her doctorate in classical philology and began seeing her first analysands soon after. She was wholeheartedly dedicated to the unconscious, both in her own life and that of her analysands. She developed a far-reaching expertise in fairytales, alchemy, synchronicity and numbers. She is estimated to have personally analyzed over 65,000 dreams.
"She was a prolific writer and a highly sought-after teacher. Listening to von Franz lecture was a numinous experience. I thought God was speaking. She seemed to know everything. In an amazing fashion and without a text, she ranged over history West and East, mythology, philosophy, anthropology, and a host of other specialized areas. Never in my training had I heard such far-reaching and profound reflections." (Murray Stein, PhD)
