Incipit: From a certain manuscript of the Philosopher R.C.

The front cover of the manuscript consists of dark brown leather with a simple gold-tooled rectangular border. The leather shows signs of age, with scuffing, scratches, and wear along the edges. In the upper center, a faded inscription is stamped into the leather, appearing as a faint impression or blind-stamping. The text is heavily worn and difficult to see clearly.

These initials likely represent a Latin motto or the owner of the book. In Rosicrucian contexts, such abbreviations often refer to concepts like "Nature, the Blessed Mother" or serve as a mnemonic for the reader to "Note Well" specific secrets within the text.
