Sulphur occupies a distinguished and irreducible position within the depth-psychological reading of alchemy. In Jung's Mysterium Coniunctionis — the locus classicus for this term in the corpus — sulphur emerges as one of the two primary archetypal substances alongside Mercurius, and the intimacy between them is so profound that the tradition itself could scarcely tell them apart. Jung identifies sulphur as the soul of metals and of all living things, the 'motive factor in consciousness,' embodying desirousness, will, and compulsion — the fiery affect principle latent in the ego. Abraham's lexicographical treatment traces sulphur's role in the Geberian sulphur-mercury theory as the active, formal, masculine principle opposed to argent vive's passive, material, feminine one. Edinger, interpreting Jung for clinical audiences, stresses sulphur's dual nature: its corruptive, poisoning, infernal aspect and its capacity, when freed from its imprisoning complexes, to become a manifestation of the Self. Hillman, characteristically oblique, approaches sulphur through colour and its vivifying power — hudor theion, Holy Water — insisting that its significance must be read within alchemical process rather than reduced to symbolic abstraction. The key tension in the corpus runs between sulphur as destructive-demonic force (the dragon, Babel, concupiscence) and as the indispensable soul-substance whose liberation is the very aim of the opus.
sulphur is a spiritual or psychic substance of universal import, of which nearly everything may be said that is said of Mercurius. Thus sulphur is the soul not only of metals but of all living things
Jung establishes sulphur as the psychic analogue of the soul, effectively equivalent in symbolic scope to Mercurius and identified with the animating principle of all existence.

sulphur or the soul is the mediating principle which unites the two contraries, body and spirit, and transforms them into one essence
Abraham defines sulphur's structural role in the Paracelsian tria prima as the mediating soul between the contrary poles of body (salt) and spirit (mercury), making it the transformative hinge of the opus.

all metals have been formed out of sulphur and quicksilver, which are the seeds of all metals, the one representing the male, and the other the female principle
Abraham presents the classical sulphur-mercury theory in which sulphur, as fire and air, constitutes the male generative principle opposite to quicksilver's female, earth-and-water nature.

I understand the dissolving of Sulphur to mean psychologically that one frees the affect from the complexes in which it first expresses itself. If one can succeed in doing that, then Sulphur is freed so to speak, and in its free form it is seen to be a manifestation of the Self.
Edinger translates the alchemical injunction to dissolve sulphur into clinical language: liberating affect from its complex-bound form reveals sulphur as a direct expression of the Self.

Another name for sulfur is hudor theion, Holy Water, because of its vivifying power in bringing about substantive change. These changes are intensely sensate
Hillman relocates sulphur within the phenomenology of colour and sensate process, identifying it with Holy Water and insisting its significance inheres in concrete alchemical transformation rather than abstract symbolism.

The dragon whose nature sulphur shares is often spoken of as the 'dragon of Babel'... a 'most pernicious poison.' ... Sulphur here plays an evil role that accords well with the sinful 'Babel.'
Jung explores sulphur's demonic pole: through its identification with the dragon and the serpent of paradise, it carries the destructive, poisonous, and concupiscent dimension of psychic energy.

sulphur has been considered the earthly manifestation of Sol. Jung speaks of it as representing the principle of desirousness, will, compulsion and the 'motive factor in consciousness.'
Edinger summarizes Jung's condensed psychological characterization of sulphur as Sol's earthly expression and the psychic principle of compulsive desire and motivated consciousness.

Sulphur, the principle of combustibility, possessed the hotness and dryness of fire and so was analogous with fire, while mercury was cold and moist and analogous with water.
Abraham grounds the sulphur-mercury binary in elemental theory: sulphur as hot and dry fire, the active combustive principle, defines the formal quality of all metals.

Philosophical 'sulphur' and 'mercury' do not refer to the substances we now call by those names, but are internal, constitutive principles or abstract, essential qualities.
Abraham establishes that philosophical sulphur is an abstract formal principle rather than a literal substance, a clarification fundamental to the depth-psychological reading of alchemical texts.

Sulphur auratum antimonii, like gold-sulphur, indicates the strong predominance of sulphur in combination with antimony. Sulphur, as we have seen, is the active substance of Sol and is foul-smelling
Jung connects sulphur to the solar active principle through its chemical manifestation in gold-sulphur of antimony, reinforcing its dual character as both luminous solar substance and malodorous corruption.

all his thoughts were absorbed by the subject of Sulphur... he lifted up his voice, and in the bitterness of his heart, cursed Sulphur. Now Sulphur was in that grove, though the Alchemist did not know it.
Edinger presents the alchemical parable of the alchemist unknowingly cursing Sulphur in its own presence, illustrating the unconscious autonomy of sulphur as a psychic factor.

The green colour attributed to Sulphur he has in common with Venus... Venus says: 'Transparent / green / and fair to view I am commixt of every hue / Yet in me's a Red Spirit hid... And he did from my husband come / The noble Mars, full quarrelsome.' The 'red spirit' is our Sulphur—'painter of all colours.'
Jung identifies sulphur as the hidden red spirit within Venus's green, designating it 'painter of all colours' and linking it to martial desire and creative chromatic power.

At the beginning of the opus the alchemist takes the prima materia which contains the seeds of metals, philosophical sulphur (male, hot, dry, active) and philosophical argent vive (female, cold, moist, receptive) and unites them in a coniunctio
Abraham situates sulphur structurally at the inception of the opus as the active male seed that enters the coniunctio with argent vive, the sequence leading through nigredo to the white stone.

sulphur is the soul... of all living things;... it is equated with 'nostra anima' (our soul).... Paracelsus likewise calls sulphur the soul. CW 14, §136
Hillman cites Jung directly to establish the equation of sulphur with the soul (anima) and with Venus's green attribute, embedding sulphur within the anima complex.

Sulphur est omne id quod incenditur... Sulphur enim aliud nihil est quam purus ignis occultus in mercurio... simplex ignis vivus, alia corpora mortua vivificans.
A Latin source passage cited by Jung defines sulphur as the hidden pure fire within mercury, the simple living fire that vivifies all dead bodies — the primordial animating function.

This aqua permanens is the Image (divine water), the 'divinity' being sulphur. It was called 'sulphur water'... and is the same as mercury.
Jung notes the Greek equation of the divine water (hudor theion) with sulphur, reinforcing the convergence of sulphur and mercury as synonymous arcane substances.
