Claude Fable 5.1 Solves the Cyphral Distich

A report describes how Claude Fable 5.1 reportedly solved Sir Thomas Urquhart’s long-unsolved 64-number Cyphral Distich by recognizing that its two 32-number lines correspond to the 32 “Proquiritations” printed immediately before it, with each number indexing a word whose initial letter forms the message, “O GOD UPHOLD KING CHARLS THE SECOND AND MAKE HIM THE SUPREME RULER OF THIS LAND.” The proposed solution is supported by its rhyming two-line structure and Urquhart’s Royalist politics, and the same book-internal indexing principle was then applied to Urquhart’s larger 285-number Cyphral Octastich in The Jewel, using each successive book page and a numbered word on that page to recover a Royalist prayer for Charles II. Although most of the Octastich decodes coherently, the account notes unresolved letters, possible printing or transcription errors, and a page-offset shift in later positions that require consultation of physical copies for confirmation. The author says the model reached the Distich solution after 44 minutes of autonomous work, aided chiefly by encouragement to seek tractable unsolved ciphers, and argues that the result illustrates how persistent AI systems may help investigate historical puzzles and other problems previously limited by human attention.
