Claude Fable 5.1 Solves the Cyphral Distich, a 370-year-old cipher

AI summary

Claude Fable 5.1 has reportedly solved the 370-year-old Cyphral Octastick cipher found in "The Jewel" (1652). The method involves using numbers from the octastick and decagram as page indices, then extracting the first letter of a word from page k. This revealed a royalist prayer from March 1652, though some parts, like "C-O-N-E-R-T-H-T-O" in line 5, remain unreadable due to potential slips or misprints.
