The cave occupies a position of singular density in the depth-psychology corpus, functioning simultaneously as cosmogonic sanctuary, initiatory threshold, oracular womb, and symbol of the collective unconscious itself. Campbell treats the Paleolithic cave as the first mythogenetic zone in human history — the literal grotto evoking, through a kind of sign-stimulus resonance, the ‘labyrinthine chambers of the soul,’ from which all subsequent high-religious symbolism descends. The cave paintings of Lascaux and Trois-Frères anchor his argument that shamanic and magical consciousness were the inaugural human response to interiority. Kerenyi and Rohde, working from different philological angles, converge on the sacred cave as dwelling-place of chthonic deity — the Idaean and Dictaean caves of Crete, the cave of Zeus Trophonios, and the Korykian cave sacred to Dionysus and Apollo all attest to the Greek identification of underground enclosure with divine presence and initiatory secret. Jung and his school read the cave as the crypt of the psyche, a pre-Christian locus of transformation, death, and rebirth. Ruth Padel situates it within Greek tragic epistemology as a site where darkness yields prophetic knowledge. Across these traditions, the cave persists as the archetype of interior space: the place where the human being, stripped of solar orientation, encounters what is oldest, most numinous, and most transformative in the cosmos.
