The Red Sun occupies a singular position in the depth-psychological corpus as an image that condenses the paradox of illumination from below—a solar radiance encountered not in the heights but in the subterranean, aqueous dark. Its most architecturally decisive appearance is in Jung's Red Book, where it blazes at the nadir of an inner cave, shining through black water and attended by serpents: a chthonic counter-sun that inverts the familiar solar principle and discloses light as an underworld phenomenon. This vision resonates directly with the Iranian Sufi tradition as rendered by Henry Corbin, where Najm Kobrā's visionary apperceptions of a red sun on a black ground announce angelophany—the Angel-Logos manifesting as what Corbin calls the 'midnight sun,' a paradoxical luminous Night. Both streams draw on alchemical precedent: the rubedo, the red tincture, the Sol niger transformed. In alchemical imagery catalogued by Abraham and theorized by Jung in Mysterium Coniunctionis and Psychology and Alchemy, red solar symbolism marks the culminating transmutative phase—the reddening that follows whiteness, gold concealed within darkness. The Red Sun thus stands at the convergence of visionary phenomenology, Sufi angelology, and alchemical psychology, functioning across these traditions as an emblem of the transformative encounter with depth that simultaneously wounds and illuminates.
In the deepest reach of the stream shines a red sun, radiating through the dark water. There I see—and a terror seizes me—small serpents on the dark rock walls, striving toward the depths, where the sun shines.
Jung's foundational vision in Liber Novus posits the Red Sun as a chthonic solar force radiating from the absolute nadir of an underworld stream, generating terror and drawing serpentine energies toward its subterranean light.

the red sun standing out on a black background, now the constellations turning red against the background of an emerald Sky… this red sun and these reddening orbs announce the presence of the Angel-Logos or of one of the angelic Intelligences.
Corbin demonstrates that in Najm Kobrā's Sufi visionary practice, the red sun on a black ground is a specific signal of angelophany, identified with the 'midnight sun' as the initial theophany of the hidden divine.

The red elixir, red rose and red king. From 'Incipit Liber qui intitulatus Praetiosum Donum Dei' (sixteenth century).
Abraham's alchemical iconography places the red solar principle within the symbolic cluster of red elixir, red rose, and red king, establishing the rubedo complex from which the Red Sun draws its transmutative meaning.

The sun was thought to have magically transformative rays which, when they penetrated the earth's crust, provided the generative warmth to ripen such imperfect metals as iron, copper and lead into the perfect metal, gold.
Abraham documents the alchemical doctrine of solar rays penetrating into underground matter to generate gold—a cosmological background that deepens the symbolic logic of a sun encountered beneath the earth's surface.

black sun, 110, fig. 34… rubedo… iosis, 229; see also red
Jung's indexical mapping in Psychology and Alchemy explicitly links the black sun to the rubedo and iosis phases, situating the Red Sun within the chromatic sequence of alchemical transformation.

the divine red tincture flushes the white stone with its rich red colour… The reddening of the white matter is also frequently likened to staining with blood.
Abraham's entry on rubedo describes the reddening of the alchemical stone as an infusion of divine red tincture analogous to blood—a process that parallels the violent, wounding luminosity of the subterranean Red Sun.

If a white woman is married to a red husband, they embrace and conceive. They dissolve of themselves, they sooner or later are perfected of themselves.
The red-white coniunctio of the alchemical 'Red Man and White Woman' provides the oppositional matrix within which the Red Sun functions as the active, masculine, fiery solar pole driving transformation.

antimony pentasulphide, 'gold-sulphur' (Sulphur auratum antimonii) is orange-red… The sunken king of alchemy went on living as the 'metal king.'
Jung traces the sunken alchemical king—an image of the solar principle descended into matter—through antimony's orange-red coloration, linking subterranean metallurgy to the phenomenology of the hidden red sun.

robe of light, theme of the, 31, 91… Rose Garden of Mystery (Golshan-e Raz), 110-120, 126
Corbin's index clusters the Red Sun's visionary context within the broader Sufi symbolic field of the robe of light and the Rose Garden of Mystery, confirming the angelophanic register of the image.

a schizophrenic patient in whose cosmic system the Father-God had a tree of life growing out of his breast. It bore red and white fruits.
Jung's clinical aside documents spontaneous red-and-white solar-arboreal imagery in a schizophrenic patient's cosmology, suggesting the Red Sun participates in a broader autonomous archetypal configuration.
