Major breakthrough! A Dutch scholar has finally decoded the cryptic B script from the Dead Sea Scrolls after over 70 years. Using rigorous paleography and statistical analysis against the Hebrew Bible and Qumran corpus, they found it uses a monographic substitution cipher where each Hebrew letter maps to one cryptic sign. The newly readable texts echo familiar biblical themes, and scholars now believe this was a scribal prestige practice rather than a way to hide information
Dutch scholar deciphers cryptic B script from Dead Sea Scrolls after 70+ years
Key facts
- A Dutch scholar cracked the cryptic B script from the Dead Sea Scrolls more than 70 years after their discovery in the 1940s-50s
- The script had only two small manuscripts and a few dozen fragments, lacking enough material for traditional decoding
- The cipher was cracked using rigorous paleography and statistical pattern matching against the Hebrew Bible and Qumran corpus
- A monographic substitution cipher was found where each letter in the Hebrew alphabet maps to one cryptic sign
- The newly readable texts echo familiar biblical themes found throughout the scrolls
- Scholars now believe cryptic B was a scribal practice conferring prestige rather than a way to conceal information
- The decipherment removes one of the last barriers to full textual analysis of the Qumran library
