The Nixie occupies a distinctive and recurring position in the depth-psychological corpus as an emblematic figure of the anima in her elemental, non-human aspect. Across Jung's own writings — from the alchemical commentaries of the Collected Works to the mythological essays co-authored with Kerényi — the nixie appears as a water-spirit whose fish-tail or aquatic nature signals the threshold between human consciousness and the undifferentiated depths of the unconscious. Jung treats the nixie as both a Kore-variant and a manifestation of the anima proper: she is that figure whom the adept 'catches' in the Liber mutus image, just as she is identified in the index to the Practice of Psychotherapy as an explicit guise of the anima. Emma Jung's treatment of Melusine enriches this picture, foregrounding the nixie-form as the secret, renewing, non-human element that must periodically be honored and not violated. Jung's alchemical commentary on Paracelsus extends the figure further: Melusina as water-nixie, stirred into human form by the Scaiolae (the psychic functions), embodies the transformative encounter with the feminine unconscious in its most numinous register. The tension in the corpus runs between the nixie as seductive, potentially fatal lure and as the carrier of the liquor Sophiae — wisdom distilled from the very deceptions she embodies.
Melusina, being a water-nixie, is closely connected with Morgana, the 'sea-born,' whose classical counterpart is Aphrodite, the 'foam-born.' Union with the feminine personification of the unconscious is, as we have seen, a well-nigh eschatological experience
Jung identifies Melusina-as-nixie with Morgana and Aphrodite, framing union with this water-spirit as an eschatological encounter with the feminine unconscious.

as imaginatio, speculatio, phantasia, and fides, they 'intervene' and stimulate Melusina, the water-nixie, to change herself into human form. Dorn thinks of this as a 'vision appearing in the mind' and not as a projection on a real woman.
Jung explicates Paracelsus's Melusina as a water-nixie who is activated into human form by the four psychic functions, constituting an inner vision rather than an outer projection.

Melusine's condition was that she be allowed once a week to return to her element and resume her nixie form. This is the secret which may not be spied upon. The non-human, the natural, in this case the fish tail, must not be seen.
Emma Jung reads Melusine's periodic return to nixie form as the necessary renewal of the non-human, elemental dimension of the psyche — a secret that must not be violated.

The 'acts of Melusina' are deceptive phantasms compounded of supreme sense and the most pernicious nonsense, a veritable veil of Maya which lures and leads every mortal astray.
Jung characterizes the nixie's acts as simultaneously wisdom-bearing and deceptive, requiring a discriminative distillation process to extract the liquor Sophiae from illusion.

An occasional variant is the nixie or water-sprite, who betrays her superhuman nature by her fish-tail. Sometimes the Kore and mother figures slither down altogether to the animal kingdom
Jung identifies the nixie as an occasional modulation of the Kore archetype, distinguished by her fish-tail as a mark of superhuman, non-human nature.

He is fishing, and has caught a nixie. His soror mystica, however, catches birds in her net, symbolizing the animus. The idea of the anima often turns up in the literature of the 16th and 17th cent.
Jung cites the Liber mutus image of the adept fishing up a nixie as an iconographic expression of the anima, paired with the soror mystica's capture of animus-birds.

Emma Jung's footnotes cite Grimm's Deutsche Mythologie as a source for nixie and related water-spirit lore, situating the figure within the Germanic folkloric tradition underlying the depth-psychological appropriation.
