Mutus Liber: Plate 12

In a rural landscape, a sheep stands on the left and a bull on the right, flanking a triangular arrangement of six shallow, bowl-like vessels placed on the ground in the foreground. Above them, a large, radiant triangle of light descends from the sky, its rays illuminating a small church with a steeple nestled in the rolling hills. In the top corners of the sky, a sun with a human face appears on the left, and a crescent moon with a human face appears on the right. The scene is rendered in dense black-and-white hatching, typical of 17th-century engraving.

This image is the twelfth plate of the 'Mutus Liber' (The Silent Book), a cryptic 17th-century alchemical text that conveys its instructions entirely through imagery rather than prose. It represents a stage of the alchemical 'Great Work' often associated with the union of opposites, represented here by the solar and lunar motifs and the juxtaposition of the ram and bull, leading toward the 'fixation' or illumination of the material.
