Decapitation occupies a surprisingly rich and differentiated position across the depth-psychology corpus, functioning simultaneously as an alchemical operation, a traumatic intrapsychic event, a mythological motif, and a cultural-historical index. Jung anchors the term most rigorously within the alchemical tradition: in the visions of Zosimos and the Splendor solis imagery, the striking off of the head denotes the extraction of the arcane substance — the caelum or 'omega element' — from the solar sacrificial figure. Edinger, following Jung, specifies that beheading symbolism in alchemy represents the achievement of the unio mentalis, the preliminary dissociation of spirit from body required before higher coniunctio becomes possible. Hillman mobilizes the image more philosophically, reading French deconstruction as a cultural attempt to 'decapitate the cogito,' while noting that the guillotine blade never quite cuts through. Kalsched deploys it clinically: a dream of violent decapitation enacts an archetypal split between mind and body, the neck as integrating connector severed by a traumatic defence. The Iliad commentary (Lattimore) situates decapitation within the ethnographic register of grief-driven rage. Across all registers the term marks a threshold — a violent separation that paradoxically prepares transformation — and its tensions between literal violence and symbolic initiation remain the generative fault-line of the literature.
The decapitation in section III, v bis therefore signifies the obtaining of the arcane substance. According to the text, the figure following behind the sacrificer is named the 'Meridian of the Sun,' and his head is to be cut off.
Jung establishes decapitation in the Zosimos vision as an alchemical operation whose precise meaning is the extraction of the arcane transformative substance, identified with solar gold.

Beheading symbolism represents the extraction of the caelum — that heavenly ... This preliminary step, in itself a clear blend of Stoic philosophy and Christian psychology, is indispensable for the differentiation of consciousness.
Edinger explicitly identifies alchemical beheading with the extraction of the caelum and frames it as the necessary precondition for differentiated consciousness and the unio mentalis.

Here we have an image of a violent decapitation — an intended split between mind and body. The neck, as an integrating and connecting link between the two, is about to be severed.
Kalsched reads a patient's dream of decapitation as the archetypal defensive dissociation of mind from body enacted by the trauma-protecting psyche.

these deconstructive moves may be French modes of decapitating the cogito — freeing the mind from the singleness that I condemn as literalism ... The guillotine blade never quite cuts through.
Hillman reinterprets decapitation philosophically as an attempt to sever the cogito from literalism, arguing that French deconstruction is an incomplete alchemical analogue.

The head of a man, who had to be a first-born, was cut off and the hair plucked out. The head was then sprinkled with salt and anointed with oil ... placed under the tongue of the decapitated head. The head was set up in a room ... and the head began to speak.
Jung documents the ritual use of the decapitated head as an oracular instrument in the teraphim tradition, connecting decapitation to the magical animation of the severed head as a speaking, prophetic object.

Hillman lists decapitation among the mortificatio operations — the painful dismantling of old psychic structures — within the alchemical blueing and whitening process.

Decapitation is unusual and here shows the height of the Greeks' despair and grief. Achilleus, bereaved of Patroklos, vows to bring back Hektor's head ... modern headhunters ... are often motivated by grief and anger at the deaths of friends.
Lattimore's commentary situates Homeric decapitation within a cross-cultural ethnographic frame linking the act to extreme states of grief and retributive rage rather than ritual transformation.

It was a custom once widely spread in England and elsewhere in Europe to treat the last sheaf as the corn spirit and cutting it to say that one is 'beheading' or 'cutting the neck' of the Boba.
Onians traces the symbolic equation of decapitation with the severing of the vegetative life-force — the corn spirit's head — demonstrating the archaic identification of the head with seed and soul.

the story of Timarchos, who ... after Socrates' death descended into the cave of Trophonios and lying there it seemed to him 'his head was struck and at the same time there came a great noise and the sutures of his head parted and allowed the ψυχή to issue forth'.
Onians adduces the Trophonios incubation vision to establish that the parting of the cranial sutures — an imagined decapitation — was understood as the release of the psyche, equating head-wound with soul-liberation.

the ideals of liberty, justice and fraternity led to the illiberal, unjust, and far from fraternal, guillotine. Anything that is essentially sacramental ... becomes the enemy of the left hemisphere.
McGilchrist invokes the guillotine as the emblematic expression of left-hemisphere rationalism's destruction of the sacramental, situating historical decapitation within his neurological-cultural critique.

Barrett uses the cultural obsolescence of decapitation as a passing illustration of how legal and social systems encode norms around permissible emotional and physical acts.
