"This book traces the continued existence of the spiritual alchemy of rebirth in heterodox and specifically Boehmist circles from around 1600 to the early twentieth century. The basic claim of continuity from Boehme to Atwood argued here is not new. A particularly apt expression may be found in F. Sherwood Taylor's The Alchemists of 1949, in which the founding editor of Ambix notes 'the existence of a school of mystical alchemists whose purpose was self-regeneration.' With Boehme as an important early exponent, this 'tendency culminated in 1850' with Atwood's Suggestive Inquiry into the Hermetic Mystery. Taylor's statement, it turns out, could hardly have been more accurate yet has so far lacked the support of a comprehensive presentation. This led Principe and Newman to describe such claims of continuity regarding spiritual alchemy as mere 'conjecture' without 'clear historical evidence.' This book marshals that hitherto elusive evidence, much of it found in obscure manuscript sources, and thus documents the continuity of spiritual alchemy that links the early-modern to the modern era"--
