Clay occupies a surprisingly rich position within the depth-psychology corpus, functioning simultaneously as cosmogonic substance, alchemical prima materia, therapeutic medium, and philosophical metaphor for the relation between form and potentiality. Von Franz reads the biblical clay-man, Adam, as an encoded symbol of the Self — uncorrupted humanity fresh from divine hands, the prima materia before the fall into differentiation and ego-consciousness. Simondon, approaching the same hylomorphic schema from a philosophy of individuation, transforms clay into the paradigm case for understanding how form and matter collaborate dynamically: prepared clay is not passive stuff but a bearer of potential energy that participates actively in the individuation event. Chodorow, working in the Jungian tradition of active imagination, finds clay to be a uniquely temporalizing medium that holds affective images long enough to permit embodied dialogue between psyche and matter. Bryant invokes the Vedantic clay-pot analogy — all named transformations remain, essentially, clay — to illuminate the Yoga school’s ontology of underlying substance. Pascal’s Daniel-derived iron-and-clay feet introduce the eschatological register: divided substance as political and spiritual vulnerability. Harrison records the Orphic detail of Titans painted in white gypsum-clay before their crime, situating clay at the threshold of ritual transgression and mythic origin. Across these voices, clay serves as the depth-psychological sign of the original, the formable, and the not-yet-individuated.
