Within the depth-psychology corpus, tusks occupy a charged symbolic register at the intersection of sacrificial ritual, chthonic power, and the Terrible Feminine. The most sustained treatment appears in Joseph Campbell's ethnographic analyses of Malekulan Maki ceremonialism, where the spiraling growth of boar tusks — completing full circular revolutions through the jawbone — functions as a visible index of a man's accumulating spiritual rank and his qualification for passage through the labyrinthine threshold of death. Here the tusk is not merely an animal feature but an emblem of the soul's progressive refinement, each completed circle demanding fresh hecatombs and conferring new ritual identity. Erich Neumann approaches tusks from a diametrically opposed angle: in the iconography of the Terrible Mother, boar's tusks adorning the Gorgon and Medusa signal uroboric phallic aggression belonging to the devouring feminine, destructive teeth that must be wrested from the vagina dentata before true relation is possible. R. B. Onians situates tusks within a Paleolithic continuum of preserved life-substance, where collections of mammoth tusks arranged in deliberate order at burial sites speak to archaic beliefs about spiritual vitality residing in bone and horn. Liu I-ming, in the Taoist I Ching commentary, draws on the gelded boar's persistent tusks as a paradox: softness (castration, yielding) that does not abolish hardness (the tusk), modelling the cultivation of strength through flexibility. Together these voices reveal tusks as overdetermined symbols — simultaneously regenerative spiral, castrative weapon, ancestral life-force, and paradoxical emblem of inner toughening.
The man's spiritual life is linked to the length of his pig's tusks, which become emblematic of his growing inner stature. This pig is now a spiritual pig.
Campbell argues that spiraling boar tusks in Malekulan ritual function as a direct material index of the owner's spiritual development and rank, collapsing outer biological growth into inner transformation.

the tusks finally emerge once more, each having completed a whole circle... Tusks so treated can, with luck and good management, be induced to describe two complete circles, and there are cases in which they have been known to describe three.
Campbell documents, via Layard, the precise ritual logic whereby circular tusk growth marks successive stages of sacrificial consecration culminating in the boar's qualification as the vehicle through which a man attains life after death.

a boar bred up by his own hands and ritually consecrated, time and again, in the ceremonials of the Maki, at every stage of the development of its greatly cherished tusks.
Campbell establishes that the tusk-bearing boar is the irreplaceable ritual token representing a man's entire life-effort and spiritual status, without which the soul cannot negotiate the labyrinthine gateway to the afterlife.

The gnashing mouth of the Medusa with its boar's tusks betrays these features most plainly, while the protruding tongue is obviously connected with the phallus.
Neumann identifies boar's tusks on the Medusa as uroboric phallic attributes of the Terrible Mother, signifying the castrating devouring womb that threatens the male ego in its encounter with the Great Feminine.

boar's tusks or other animal fangs often appear beside the teeth of the Terrible Female... The winged Gorgons with snakes for hair and girdle, with their boar's tusks, beards, and outthrust tongues, are uroboric symbols of the primordial
Neumann systematically positions boar's tusks as attributes of the negative Masculine pole within the Terrible Mother archetype, marking the destructive, phallic-aggressive dimension of uroboric femininity.

to empty the mind and completely fill the belly is like the tusks of a gelded boar — the boar is soft, but the tusks are hard. Using flexibility and yielding to nurture firmness and strength
Liu I-ming employs the gelded boar's retained tusks as a Taoist paradox illustrating the alchemical principle that softening the ego-will does not eradicate strength but rather transforms it into genuine, durable inner power.

With his radiant white tusks he arrived and with those ample tusks elevated the goddess of his dream from those darkest regions.
Campbell presents Vishnu's cosmic boar avatar wielding tusks as instruments of salvific cosmological action — lifting the submerged goddess Earth — aligning the tusk's symbolic force with divine rescue and world-restoration.
