The Mutus Liber ("Silent Book") is a notable 17th-century alchemical work that consists solely of 15 illustrations, each depicting stages of the alchemical process. Unlike many other alchemical texts, it contains no written explanations, making it "silent" and open to interpretation. The images are rich with symbolism, representing various stages of spiritual and material transformation, which alchemists believed could lead to the philosopher's stone or the transmutation of base metals into gold. The Mutus Liber has been influential in alchemical tradition, often regarded as a visual guide for initiates into the mysteries of alchemy. Its enigmatic nature invites deep contemplation and has inspired many interpretations within esoteric circles.
