Strangely, despite the allusion to Hermeticism in the title of this manuscript, which was penned in the early 17th century, its content revolves not around Hermetic Philosophy so much as alchemy and natural processes. Casting off most of the metaphor and much of the veil of confusion enshrouding the meaning of such texts, "The Secret Work" not only describes alchemical workings in near-literal terms but openly and explicitly alludes to the practice of alchemists as being hidden on a deliberate level.
