Attis occupies a singular position in the depth-psychology library as the paradigmatic figure of the son-lover destroyed by the Great Mother—a mythic constellation that Jung, von Franz, Hillman, Neumann, Edinger, and Bly each mobilize for distinct theoretical purposes. Jung’s treatment in Symbols of Transformation is foundational: the castration of Attis beneath the pine tree is read as a dramatization of the sacrifice of instinctual libido, the ritual self-wounding by which the masculine principle is absorbed back into the maternal ground. The pine tree becomes the axis of this complex—simultaneously the symbol of Attis, the site of his death, and the vessel of transformation that Cybele carries into her cave. Von Franz extends this reading into the puer aeternus constellation, identifying the ‘attified’ youth as a figure who, having failed to individuate beyond the mother’s orbit, undergoes a cruciform petrification into the maternal tree. Hillman reads Attis through the senex-puer polarity, noting the bound feet, the castration motif, and the covered head as indices of a split archetype in which the youthful figure is deformed by its failure to hold the tension of opposites. Neumann situates Attis within the broader sacrificial logic of Great Mother fertility cults, and Bly draws on Frazer’s comparative apparatus to anchor the figure in the seasonal death-and-resurrection economy of Mediterranean religion. The term thus functions across the library as a diagnostic image of the masculine psyche captured, castrated, and consigned to cyclical mourning.
