The Black Sun receiving a medicinal herb (Aurora Consurgens)

A seated figure with a metallic gold head and a dark, possibly charred or blackened torso rests on a green cushion. Its lower body is pale with faint, light-colored circular spots. Facing this figure, a woman wearing a blue robe and a white coif holds out a stylized, green, herb-like object as if offering medicine or healing. The background is a flat, textured red, contrasting with the figures in the foreground. The illustration is executed in a medieval manuscript style with thick, visible outlines and limited shading.

This image originates from the 'Aurora Consurgens', a 15th-century alchemical treatise attributed to pseudo-Aquinas. It represents the 'nigredo' or blackening phase of the alchemical process, where the substance is purified or 'healed' by the philosopher-adept to facilitate transformation into the 'albedo' or white stage.
