Caballa, The Art & Nature Of Alchemy: Therefrom, What the most ancient Stone of the Sages is, which is triple, and yet the Stone exists as simple.

First printed in 1654 and long circulated among students of Hermetic philosophy, Cabala, The Mirror of Art and Nature, in Alchemy presents one of the most disciplined and internally coherent visual-textual expositions of the alchemical Art. Attributed to an "unknown, yet known" author and dedicated to the Fraternity of the Rosy Cross, the work unfolds the Great Work through a sequence of engraved figures and carefully ordered operations, revealing how Nature and Art cooperate through a single, unified process. The treatise insists that the mysteries of alchemy are not grasped through speculation alone, but through patient labor, moral preparation, and reconciliation with both God and Nature. Structured around the stages of Beginning, Middle, and End-Exaltation, Conjunction, and Multiplication-the text leads the reader toward the Fountain of Life and the "most ancient Stone of the Sages," described as triple in principle yet simple in essence. More than a historical curiosity, this work stands as a rigorous statement of classical alchemy as sacred philosophy and supreme medicine, addressed only to those willing to undertake the labor it demands.
