Sol — the sun, gold, the masculine principle, and the ego's luminous field — occupies a structurally indispensable position across the depth-psychological corpus. In Jung's alchemical studies, Sol operates at multiple registers simultaneously: as the prima materia awaiting transformation, as the gold tincture that is the goal of the opus, and as the ego-consciousness whose brilliant but partial light casts its own shadow. Jung's Mysterium Coniunctionis establishes the decisive tension: Sol must unite with Luna in the coniunctio to produce the lapis, yet Sol carries sulphurous, corrupting properties that imperil the work. The sol terrenus distinguishes an earthly, preliminary phase from the philosopher's gold, reminding the reader that solar consciousness remains raw material, not consummation. Edward Edinger, following Jung, explicates Sol's dual nature — its destructive, overwhelming luminosity on one hand, its redemptive illumination on the other — while grounding both aspects in clinical and mythic phenomenology. Thomas Moore, reading Ficino, positions Sol within a polytheistic psychic ecology: the sun-spirit is one planetary intelligence among several, its drying, purifying tendency potentially corrected by Jupiter and Venus. Abraham's alchemical dictionary anchors the symbolic pairing Sol–Luna in the chymical wedding tradition. Together these voices establish Sol not as a simple symbol of consciousness but as a dynamic force whose integration with its opposite constitutes the central drama of the individuating psyche.

Sol appears here in a dubious, indeed a 'sulphurous' light: it corrupts, obviously because of the sulphur it contains. Accordingly, Sol is the transformative substance, the prima materia as well as the gold tincture.
Jung argues that Sol is paradoxically both the corrupting agent of dissolution and the goal-substance of alchemical transformation, residing at opposite poles of the same process.
Jung, Carl Gustav, Mysterium Coniunctionis: An Inquiry into the Separation and Synthesis of Psychic Opposites in Alchemy, 1955thesis
The refulgent body of the sun is the ego and its field of consciousness — Sol et eius umbra: light without and darkness within. In the source of light there is darkness enough for any amount of projections.
Jung identifies Sol directly with ego-consciousness, insisting that its very luminosity harbors a compensatory darkness from which projections proliferate.
Jung, Carl Gustav, Mysterium Coniunctionis: An Inquiry into the Separation and Synthesis of Psychic Opposites in Alchemy, 1955thesis
Luna is the bride, the white queen and consort of King Sol. She is the moist, cold, receptive principle which must be united with Sol, the dry, hot, active principle, in the chemical wedding.
Abraham defines Sol canonically as the dry, hot, masculine counterpart to Luna in the alchemical chymical wedding, whose union generates the philosopher's stone.
Abraham, Lyndy, A Dictionary of Alchemical Imagery, 1998thesis
The rending golden rams of the sun symbolize an archetypally overpowering male-spiritual power which the feminine cannot face. It's an example of the destructive aspect of Sol.
Edinger differentiates Sol's destructive overpowering luminosity from its redemptive illumination, illustrating the former through mythic and mystical phenomenology including nuclear explosion dreams.

Dissolve then sol and luna in our dissolving water… it is necessary therefore that they enter into it again, to wit, into their mother's womb, that they may be regenerate or born again, and made more healthy, more noble, and more strong.
Edinger presents the alchemical recipe for solutio as the necessary dissolution of Sol and Luna — gold and silver — in the mercurial maternal waters as prerequisite to psychic regeneration.
Edinger, Edward F., Anatomy of the Psyche: Alchemical Symbolism in Psychotherapy, 1985thesis
Sol and Luna are being dissolved and united at the same time. This corresponds to a common type of alchemical picture in which the king and queen are bathing together in the mercurial fountain.
Edinger shows that solutio and coniunctio often coincide in alchemical imagery, with Sol and Luna co-dissolving and co-uniting in a single transformative event.

Sol… the one so important for maintaining life, so visible in its brilliance and influential in its warmth, and so obvious as to be taken for granted… the sun cannot rise and set with such grandeur and color our skins and expose our world without having immense psychological impact.
Moore, following Ficino, establishes Sol as the most psychologically pervasive planetary influence — at once omnipresent and overlooked — foundational to any imaginal psychology of the heavens.

Sol… the one so important for maintaining life, so visible in its brilliance and influential in its warmth, and so obvious as to be taken for granted… without having immense psychological impact.
Moore reiterates Sol's foundational role in Ficino's imaginal psychology, arguing that the sun's constant presence renders its psychic impact simultaneously universal and invisible.

There is less danger in Jupiter than in Sol of drying out the soul in its lofty aims; Jupiter remains close to the flow of life… Sol on the one hand and Venus and Luna on the other.
Moore articulates Sol's characteristic danger within Ficino's planetary psychology: its excessive drying force can parch the soul, requiring the moderating influence of Jupiter, Venus, and Luna.

There is less danger in Jupiter than in Sol of drying out the soul in its lofty aims; Jupiter remains close to the flow of life… Sol on the one hand and Venus and Luna on the other.
In Ficino's system Sol's solar dryness imperils the soul's vitality, requiring the mediating warmth of Jupiter, which contains elements of both Sol and the moister feminine planets.

the coniunctio of Sol and Luna — which they thought of as material in the alchemical flask. Jung continues: The Christian solution of the conflict is purely pneumatic… Alchemy, on the other hand, exalted the most heinous transgression of the law, namely incest, into a symbol of the union of opposites.
Edinger explicates Jung's comparison of Christian spiritualization and alchemical materialization of the incest problem, with Sol–Luna coniunctio as alchemy's vehicle for reconciling opposites in matter rather than spirit.

the early Church stood in a special relationship to Christ as the Sol novus… Philo Judaeus saw in the sun the image of the divine Logos, or even the deity itself. And in a hymn of St. Ambrose, Christ is invoked with the words 'O sol salutis.'
Jung traces Sol's theological transformation into the Sol novus — Christ as new sun — demonstrating how solar symbolism migrated from pagan cosmology into Christian Christology.
