Liber Primus Structural Overview

Pagination

LP2’s 58 pages all have numerical names, as defined by 3301 in their May 2014 file dump. The names of the pages are consecutive whole numbers, i.e. ‘0.jpg,1.jpg,2.jpg…57.jpg’. This is a departure from the nomenclature of LP1.

Segmentation

LP2 consists of multiple ‘sections’, easily recognized by marginalia and rubricated incipits. Stylistically reminiscent of illuminated manuscripts.

Delimiters

1:1 delimiter congruency is assumed to be maintained, as it is in LP1 and the two solved pages of LP2. Liber Primus has unique delimiters used for spaces, line breaks, paragraph, section end, etc. The dot delimiters also correspond to the ASCII control characters LF (Line Feed), CR (Carriage Return), and ETB (End of Transmission Block)

GP values

GP letter values can be used to construct prime words, phrases, and sentences/lines. Prime/emirp GP sums serve an important role as exemplified by 57.jpg

Artwork

LP contains various forms of both original and existing artwork. 1033.jpg, sometimes called the ‘cover‘ of LP, is a collage of four William Blake pieces: NewtonThe Ancient of Days, and two versions of Nebuchadnezzar. Within LP2, ‘sections’ are ostensibly indicated by original marginalia. Specific pages also contain separate, page-relevant original artwork — such as cuneiform numerals or mobius strips. Additionally, several instances of edited artwork from known sources exist — such as the mayfly and oak tree.

Bigrams
Single-rune words

In both LP1 and LP2, we see many single-rune words. Ostensibly, these can only be “A” or “I”. A third, less likely possibility also exists: “O”, used as an interjection/exclamation. William Blake, often referenced throughout the Cicada 3301 puzzles, often used “O” in this manner. When applying the Gematria Primus, it becomes apparent that single runes can be translated into two or three letter digraphs/diphthongs such as “TH”, “EO”, “NG/ING”, “OE”, “AE”, “IA/IO”, and “EA”. These additional characters make cribbing much more difficult due to the increase in possibilities that we have to work through.

Dis Legomenon

The 6-gram DJUBEI occurs twice in the corpus of unsolved LP pages, marking the longest such repetition and a possible point of attack.

Character Interchangeability

There is strong evidence to support the encryption was performed on the runes instead of the latin characters. This is due to not being able to go back and forth between runes and latin characters.

An example would be: ᛏᚻᚫᛡ -> THAEIO -> ᚦᚫᛡ
