Pothos occupies a precise and indispensable station within the depth-psychological lexicon of desire, functioning as neither mere appetite nor reciprocal love but as the irreducibly spiritual dimension of Eros — the longing that pursues what cannot be possessed. Hillman, who develops the term most extensively in the depth-psychology corpus, distinguishes Pothos from its sibling aspects of Eros: himeros designates the urgent physical appetite for the immediately present, anteros the answering mutuality of love, while Pothos names the yearning directed toward the unattainable and the incomprehensible. This tripartite classical differentiation becomes, in Hillman’s hands, a psychological typology: Pothos is love’s ‘spiritual portion,’ or equivalently, the erotic component of spirit. Its mythological anchors — Skopas’s cult statue at Samothraki, the phallic Hermes identified with Pothos, Aphrodite’s chariot drawn by this longing — allow Hillman to situate it within the puer-senex complex, where it names the driven, nostalgic, wandering restlessness that neither possession nor arrival can satisfy. Pothos connects to the blue of imagination in Hillman’s alchemical psychology, the blue larkspur placed on graves, the romantic flower that pines for what is contra naturam. Anne Carson’s use of the term in the novel Daphnis and Chloe extends Pothos into literary theory, where it seizes the reader’s relation to a text. The term thus traverses ontology, aesthetics, clinical psychology, and classical mythology.
