The main reason why serious historical studies of the Rosicrucian manifestos and their influence have hitherto been on the whole lacking is no doubt because the whole subject has been bedevilled by enthusiasts for secret societies. There is a vast literature on Rosicrucianism which assumes the existence of a secret society, founded by Christian Rosencreutz, and having a continuous existence up to modern times. In the vague and inaccurate world of so-called 'occultist' writing this assumption has produced a kind of literature which deservedly sinks below the notice of the serious historian. And when, as if often the case, the misty discussion of 'Rosicrucians' and their history becomes involved with the masonic myths, the enquirer feels that he is sinking helplessly into a bottomless bog.
