Summary Report
Claude Fable cracked Sir Thomas Urquhart's 1653 Cyphral Distich by reading the book rather than brute-forcing it, revealing a Royalist prayer for Charles II.
- 01. 44 minutes, 176,000 tokens, zero human interjections; the cypher had sat on Klaus Schmeh's top-50 unsolved list
- 02. Method: each number indexes a word in the matching section of the book; first letters spell a 32-letter rhyming couplet
Claude Fable has solved the Cyphral Distich, two lines of 32 numbers Sir Thomas Urquhart embedded in his 1653 book Logopandecteision, long listed among the top fifty unsolved encrypted messages. It took 44 minutes, 176,000 tokens and no human interjections. Rather than brute force, Fable read the surrounding text, spotted the emphasis on the number 32 and a poem pointing to the author's mind, and worked out that each number indexes a word in a matching section, take the first letter. The plaintext: O God uphold King Charles the Second and make him the supreme ruler of this land.
