A complex alchemical woodcut engraving. At the top is a stone fountain basin inscribed with "Fountain of the blessed living water." Emerging from the basin is a sun with a human face, bearing the symbol for Mercury (☿) on its forehead. Below the sun is a large circular diagram resting on a pedestal. The diagram features four small peripheral circles at the cardinal directions labeled "Man," "Mineral," "Animal," and "Vegetable." Within the main circle are several rings of text: "The mystery of nature is perfected in the subtle," "By water alone it becomes the medium," and "The medium through which everything that comes is perfected." A central square/diamond contains the labels for the Tria Prima: "Spirit Mercury (☿)," "Soul Sulfur (🜍)," and "Body Salt (🜔)," along with "Seed." The very center contains four triangles representing the classical elements: Fire (🜂), Air (🜁), Water (🜄), and Earth (🜃). The diagram also includes the words "Nature," "Art," and "Solution."
