The horse occupies an exceptionally dense symbolic field in the depth-psychology corpus, functioning simultaneously as cosmological body, instinctual force, psychopomp, and mediator between consciousness and the unconscious. Jung’s treatment in Symbols of Transformation establishes the foundational polarity: the horse as world-body (the Vedic sacrificial horse whose anatomy maps the cosmos) and as libidinal carrier of the mother-bound hero who ‘cannot hold his horses.’ Hillman deepens and complicates this by insisting that the standard chthonic-Poseidonic symbolism be held alongside the horse’s airy, Martian, and tenderly somatic dimensions — its delicacy no less than its force. Von Franz attends to the horse as fairy-tale helper, a figure through which the psyche negotiates with demonic or unconscious powers, and as the concrete vehicle through which an intuitive type may be initiated into instinctive, embodied reality. Eliade situates the horse within shamanic trance as the literal mount of the god riding the possessed medium. Burkert and Campbell press the mythological record — Poseidon’s generation of the horse from rock and Gorgon, the October Horse sacrifice to Mars, the Vedic aśvamedha — into evidence for the animal’s irreducible connection to sovereignty, sacred violence, and cosmogonic sexuality. Signell and Bly read the horse clinically and narratologically in terms of energy, wholeness (the four-legged versus three-legged horse), and the feminine spirit’s drive toward freedom. The tension that runs throughout is between domestication and wildness, between the horse as instrument of human will and as autonomous numinous presence.
