Red Sulphur occupies a distinctive niche within the depth-psychological reception of alchemical symbolism, functioning primarily as a designation for the raw, instinct-laden, emotionally compulsive substrate of psychic life. The term enters the corpus principally through Arabic alchemy — most visibly in the iconography of the wingless bird that prevents the winged bird from ascending — and is interpreted by Marie-Louise von Franz as the prima materia of every analytic encounter: what must first be unearthed before transformation can proceed. For von Franz, red sulphur designates the instinctive drives in their unrefined, fire-colored urgency, a factor simultaneously feminine (as the lower, receptive pole) and masculine (as active compulsion), collapsing the usual gender binaries of alchemical theory. Jung situates red sulphur within his broader account of sulphur as the soul-substance and the 'motive factor in consciousness,' identifying it more specifically with passionate emotionality and the preconditions for recognizing unconscious contents. The paired image of the red and white sulphur — lion and lioness, wingless and winged — maps onto the tension between unredeemed affect and spiritualized psyche that drives the coniunctio toward resolution. Edward Edinger amplifies this: dissolving sulphur psychologically means freeing affect from the complex that imprisons it, a movement toward the Self. Across these voices the term marks the irreducible earthward pull without whose acknowledgment individuation cannot begin.
the wingless bird, the red sulphur, is an underlying factor of the inner psychic life and is always what one has first to unearth, for it is the prima materia.
Von Franz identifies red sulphur as the irreducible prima materia of psychic work — the instinctive, drive-laden understructure that must be encountered before any transformation is possible.

a furious battle between the wingless lion (red sulphur) and the winged lioness (white sulphur). The two lions are prefigurations of the royal pair... Evidently at this stage there is still a good deal of bickering between them, and this is precisely what the fiery lion is intended to express — the passionate emotionality that precedes the recognition of unconscious contents.
Jung reads the red sulphur / white sulphur polarity as a pre-coniunctio battle of opposites, with red sulphur specifically indexing the passionate emotionality that must be metabolized before unconscious contents can be integrated.

The red colour refers to fire the emotional quality. The wingless bird is the red sulphur; it is the bird below, and is also referred to as the female, so that we have a paradox because, being driven, it is regarded as the male active quality but projected onto the lower bird it is the female.
Von Franz elaborates the paradoxical gender coding of red sulphur — simultaneously active/masculine in its compulsive drive quality and feminine as the lower, earth-bound pole — exposing the instability of alchemical gender categories around this term.

Von Franz's index confirms that red sulphur receives sustained, concentrated treatment across multiple consecutive lecture pages, signalling its structural importance to her psychological reading of Arabic alchemy.

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 the broader psychological valence of sulphur as soul-substance, providing the theoretical ground from which the more specific designation 'red sulphur' draws its meaning as concentrated emotional and instinctual affect.

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 instruction to 'dissolve the Sulphur' into a clinical telos: liberating affect from its complex-bound imprisonment reveals sulphur — including in its red, instinctive form — as ultimately a manifestation of the Self.

sulphur... represents the principle of desirousness, will, compulsion and the 'motive factor in consciousness.'
Edinger distils Jung's psychological characterisation of sulphur as the principle of compulsive desire and motivating will, the affective fuel that, when coloured red, marks the raw, unredeemed phase of this energy.

antimony pentasulphide, 'gold-sulphur' (Sulphur auratum antimonii) is orange-red... Sulphur, as we have seen, is the active substance of Sol and is foul-smelling.
Jung connects the orange-red coloration of sulphur compounds to Sol's active principle, providing material-chemical grounding for the chromatic coding that defines 'red sulphur' as the heated, solar, activating face of the sulphur archetype.

Venus says: 'Yet in me's a Red Spirit hid / No name I know by which he's bid / And he did from my husband come / The noble Mars, full quarrelsome.' The 'red spirit' is our Sulphur — 'painter of all colours.'
Jung cites this verse from the Gemma gemmarum to illustrate sulphur as the hidden red spirit within Venus, linking martial aggressivity and fiery coloration to sulphur's role as universal tincturing agent.

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's excursus on sulfur foregrounds its vivifying, sensate dimension, a perspective that complements the red sulphur's status as the passionate, body-embedded factor in the alchemical-psychological drama.

the 'winged dragon' that stands for quicksilver becomes a poison-breathing monster only after its Jungian with the 'wingless dragon,' which corresponds to sulphur.
Jung's account of the wingless dragon as sulphur's correlate in the dragon dyad parallels the wingless-bird symbolism of red sulphur, confirming the structural pairing of the grounded, compulsive principle with a volatile, mercurial counterpart.
