This paper presents a theoretical synthesis exploring Garmr, the mythic wolf of Norse cosmology, as an archetype of the death threshold within a Jungian framework. Drawing from depth psychology, Norse mythology, and cultural history, it argues that Garmr embodies the boundary between life and death, consciousness and unconsciousness, representing the psychological process of confronting repressed material and shadow aspects. Unlike other mythic wolves whose narratives emphasize destruction, Garmr’s role is as guardian and challenger at the threshold of transformation, symbolizing the necessary psychic confrontation for individuation and renewal. This synthesis integrates clinical insights on grief, trauma, and ego dissolution with archaeological and mythological evidence rooted in Danish cultural landscapes, providing a holistic understanding of how threshold archetypes operate across personal and cultural levels. By situating Garmr as a central figure in both psychological theory and Northern European tradition, the paper offers a unique contribution to the study of archetypes by highlighting the intersection of myth, psyche, and place. Implications for clinical practice include recognizing archetypal symbols as facilitators of healing through the integration of unconscious material. The paper also calls for further research on underexplored mythic figures as valuable psychological constructs within diverse cultural contexts.
