Cybele — the Phrygian Magna Mater whose cult spread from Anatolia across the Hellenistic and Roman worlds — occupies a significant, if unevenly theorised, position in the depth-psychology corpus. The dominant reading, most fully elaborated by Jung in Symbols of Transformation, treats Cybele as an exemplary figure of the devouring, incestuous mother: her relationship with Attis dramatises the ego’s peril before an overwhelming maternal libido, culminating in self-castration as both catastrophe and sacrifice of the animal nature. Neumann amplifies this reading in The Origins and History of Consciousness and The Great Mother, situating Cybele within the broad stratum of Great Mother worship — a stage of psychic development characterised by son-lover mythology, fertility rites, and the not-yet-differentiated masculine ego. Robert Bly, drawing on Frazer, extends the motif anthropologically to argue that the ‘Boy-Who-Would-Be-Wounded’ served Cybele-type cultures as a literal sacrificial surrogate for vegetative death. Liz Greene’s glossary entry in The Astrology of Fate offers the most compact mythological précis, stressing the bloody, madness-inducing quality of the cult. Rank’s index entry links Cybele to birth-trauma theory, while Kerenyi mentions ‘Kybele’ in passing within Dionysian contexts. Across these voices a consistent tension holds: Cybele is simultaneously archetype of nourishing earth and engine of masculine self-annihilation.
