Within the depth-psychology corpus, Styx occupies a position at the intersection of cosmogony, oath-theology, and psychic boundary. The river is not merely a topographical feature of the Greek underworld but a primordial force: Hesiod’s Theogony identifies Styx as the eldest daughter of Ocean and Tethys, wife of Pallas, and the very substance by which the gods swear their most binding oaths — a role Hesiod links directly to her early loyalty to Zeus during the Titanomachy. This cosmic function as guarantor of inviolable commitment extends into depth-psychological territory most forcefully in Hillman, who reads the ego’s self-preserving hatred as a ‘Stygian enactment in the upperworld,’ making each person a Child of Styx when pursuing pain-avoidance at the expense of warmth and relation. Nagy’s philological work adds a paradox: the waters associated with death and hateful cold are simultaneously an elixir capable of conferring immortality — the aphthiton quality sworn by the Styx applies to Achilles’ timē, collapsing the boundary between the lethal and the imperishable. Greene treats Charon’s crossing as descent-psychology, the stripping of ego-property required by any genuine underworld transit. Vernant documents Styx’s chthonic physicality — the Arcadian stream that destroys every vessel — while Kerenyi traces the etymology through stygein, ‘to hate,’ anchoring the river’s mythological affect in linguistic bedrock.
Freud’s fantasy that the ego must preserve itself by struggle… is a Stygian enactment in the upperworld. The ego here becomes Styx’s instrument, a Child of Hatred, icily preserving itself against all enemies
Hillman argues that Freud’s ego-psychology unwittingly enacts the Stygian principle — hatred as self-preservation — transposing an underworld force into upper-world psychic economy.

the hero gets a tīmē that is aphthitos because the goddess swears by the Styx, which is itself aphthitos… the waters of the Styx are an elixir of life.
Nagy demonstrates that the Styx paradoxically confers immortality as well as marking death, linking the oath-substance to the imperishable timē of heroic kleos.

Styx is to us a hated name; it is associated with stygein, ‘to hate’. It is the name of the river that nine times encircles and confines the Underworld.
Kerenyi grounds the mythological affect of Styx in its etymology — the root stygein, ‘to hate’ — while locating the river as the encompassing boundary of the underworld.

there dwells the goddess loathed by the deathless gods, terrible Styx, eldest daughter of back-flo[wing Ocean]
Hesiod’s Theogony establishes Styx as a primordial underworld deity — daughter of Ocean, loathed even by the immortals — making her repulsion structurally constitutive of divine order.

The souls of the dead must cross the river Styx, ferried by the ancient boatman Charon who demands his coin in exchange… something of value that is one’s own possession… must be given away during the descent
Greene reads the Stygian crossing as a depth-psychological rite of ego-surrender, in which the toll exacted by Charon figures the loss of identity-props required by genuine underworld descent.
