In this book, an attempt has been made to convey something like an intelligible idea of the peculiar mystic sect known to the readers of history, as the Rosicrucians. The subject is confessedly difficult, owing to the grossly absurd character of the writings left by the disciples of this body, and the secrecy with which they sought to surround their movements and clothe their words. Anything like a consecutive narration is an impossibility, the materials at hand being so fragmentary and disjointed. We have, however, done the best that we could with such facts as were within reach, and if we are not able to present so scientific and perfect a treatise as we might have hoped to do, we at least trust that the following contribution to the scanty literature treating of this matter will be found interesting, and will throw some light upon what is shrouded in such profound mystery.
