In 1912, Carl Jung published 'Psychology of the Unconscious,' breaking with Freud and proposing the concept of the 'collective unconscious' populated by universal archetypes shared across cultures. Jung's ideas expanded the field of psychology, introducing new dimensions to understanding human behavior and cultural phenomena. His theories have influenced various disciplines, including literature, art, and religious studies, shaping contemporary thought on the psyche.

Carl Jung's 'Psychology of the Unconscious' introduced a mythic vocabulary that resonated deeply with poets seeking to explore the human psyche. His archetypal framework influenced poets like Rainer Maria Rilke, who sought universal themes in their personal expressions.
