Hargrave Jennings presents a fascinating look at and interpretation of the philosophy and nature of the Rosicrucian Order in this classic work. It is an indispensable work for any student of the Rosicrucians or the Mysteries Schools. This book, which now leaves our hands, concentrates in a small compass the results of very considerable labour, and the diligent study of very many books in languages living and dead. It purports to be a history (for the first time treated seriously in English) of the famous Order of the 'Rose-Cross', or of the 'Rosicrucians'. No student of the occult philosophy need, however, fear that we shall not most carefully keep guard--standing sentry (so to speak) not only over this, which is, by far, the pre-eminent, but also over those other recondite systems which are connected with the illustrious Rosicrucians.
