The term ‘horn’ occupies a remarkably dense symbolic field within the depth-psychology corpus, operating simultaneously as anatomical fact, mythological emblem, and carrier of numinous power. Onians furnishes the most systematic treatment, tracing the philological kinship between ‘horn,’ ‘brain,’ and ‘cerebrum’ across Greek, Latin, and Germanic roots to argue that horns were understood as outcroppings of the procreative life-substance concentrated in the head — a thesis that illuminates Horn imagery from Homer’s gate of true dreams (kerata) to the cornucopia and the cuckold’s horns. Burkert situates the ‘horns of consecration’ within Minoan-Mycenaean cult practice, showing how the geometric stylization of bovine horn symbols on altars and shrine facades preserves an archaic sanctity that outlasts its zoomorphic origin. Jung engages the horn principally through the unicorn, reading the single horn as an alchemical-Christological symbol of power, purity, and the coniunctio of opposites, while noting the Psalmic equation of the exalted horn with vitality and divine might. Jung also demonstrates, via the shofar passage, that the symbol lives or dies by the consciousness brought to it: a ram’s horn is merely keratin until symbolic intention transforms it into the voice of covenant. The Winnebago figure of Red Horn in Radin adds a cross-cultural mythological axis. Taken together, these voices reveal ‘horn’ as a nexus of procreation, power, consecration, and psychic transformation.
