Escorted by his beloved friend, Lady Symbol Quartermaine, Pilgrim is admitted to the famous Burgholzu Psychiatrist Clinic In Zurichm, where he will begin a battle of psyche and soul with Carl Jung, the self-professed mystical scientist of the unconscious Slowly, Jung coaxes Pilgrim to tell his astonishing story—one that seemingly spans 4,000 years and includes such historical figures as Leonardo da Vinci and Henry James.
