The bull occupies a position of exceptional density in the depth-psychology corpus, functioning simultaneously as cosmogonic force, sacrificial vehicle, erotic power, and—in Hillman’s audacious reading—the very origin of language and imagination itself. No single interpretation dominates; the passages reveal productive tension among several axes of meaning. Hillman treats the bull as the ur-image of mythological imagination: the first letter aleph is a bull-face, and all hyperbolic, fertile, excessive speech carries the bull’s generative excess within it. Kerenyi links the bull inseparably to Dionysus—as wine god, bull god, and god of women—tracing Minoan antecedents. Campbell illuminates the sacrificial theology operative in Mesopotamian, Egyptian, and Cretan bull-rites, where the animal mediates between royal power and cosmic renewal. Harrison’s philological and ritual scholarship recovers the Year-Bull at Magnesia and the bull-driving Dithyramb, grounding the symbol in agrarian cult. Jung and Jungian interpreters read the bull as the instinctual-natural stratum threatened by ego-civilization: Mithras kills the bull so that Christianity may emerge, but the killing is simultaneously a loss. Greene’s astrological frame introduces Taurus as the domain of Minoan-type hoarding power versus sacred gift. Together these voices construct the bull as perhaps the most polyvalent animal archetype in the Western psychological tradition—excessive, fertile, sacrificial, and irreducible.
