Subject: Book Cipher Finally Read
The Gist:
The article says Claude Fable 5.1 selected and solved Sir Thomas Urquhart’s 1653 Cyphral Distich in 44 minutes using 176,000 tokens. It recognized that the two rows of 32 numbers correspond to the 32 preceding “Proquiritations”: number i indexes a word in paragraph i, whose initial supplies a plaintext letter. The result is a Royalist prayer for Charles II. The model then applied a page-based variant to Urquhart’s longer Cyphral Octastich, recovering nearly all of another Royalist poem.
Key Claims/Facts:
- Distich method: Pair each of 32 numbers with its corresponding Proquiritation, select that numbered word, and take its first letter.
- Decoded message: “O GOD UPHOLD KING CHARLS THE SECOND AND / MAKE HIM THE SUPREME RULER OF THIS LAND,” matching Urquhart’s politics and the promised two-line form.
- Broader claim: The model’s notable strength was finding a tractable neglected problem and persistently testing it; the Octastich result remains partly uncertain because of nine unreadable letters, apparent printing/transcription issues, and unavailable page images.
Discussion Summary (Model: gpt-5.6-sol)
Consensus: Skeptical but impressed: commenters generally accept that the decoding is plausible and useful, while strongly disputing the “370 years of human failure” framing and its value as evidence of exceptional AI reasoning.
