The occluded light — the sun behind the sun.
/// history
The Black Sun (Schwarze Sonne) as an esoteric concept precedes its most notorious modern incarnation. In alchemy it represents the phase of nigredo — the darkening, putrefaction, and dissolution that must precede any genuine transformation. Saturn-Sol niger, the black sun, appears in alchemical texts from the 16th century onward as a symbol of the prima materia in its most opaque form. The twelve-spoke wheel version was popularised in the 20th century when it was set into the marble floor of Wewelsburg Castle under Heinrich Himmler, catastrophically associating the symbol with National Socialism.
/// occult_meaning
Stripped of its ideological contamination and returned to its alchemical context, the Black Sun represents the hidden solar intelligence — the spiritual sun that illuminates the inner world rather than the outer. In Sufi mysticism a similar concept appears as Akhdar, the green sun of the imaginal realm. In depth psychology it corresponds to the night-sea journey, the ego's descent into the unconscious before the dawning of renewed selfhood. It is the sun of midnight initiations.
/// modern_interpretation
The Black Sun is a symbol that requires careful contextualisation given its recent history of misappropriation. In serious esoteric traditions it describes a mystical experience of inner illumination accessible only through total surrender of surface identity — what mystics of every tradition describe as the dark night of the soul.
