Dead Sea Scrolls' Last Secret Cracked: 70-Year-Old 'Cryptic B' Code Deciphered
Dead Sea Scrolls' final code deciphered after 70 years

After more than seven decades, one of the last great mysteries of the Dead Sea Scrolls has finally been solved. A researcher has successfully deciphered the enigmatic 'Cryptic B' script, unlocking the secrets of two ancient fragments that were long considered unreadable.

The 'Impossible' Code and its Cipher

The breakthrough, achieved by Dr Emmanuel Oliveiro of the University of Groningen, centres on two heavily damaged manuscripts labelled 4Q362 and 4Q363. For years, scholars believed these texts were 'impossible' to read because they used an unfamiliar, cryptic alphabet. Dr Oliveiro determined that each strange symbol consistently corresponded to a letter in the Hebrew alphabet, effectively cracking the code.

The Dead Sea Scrolls themselves were discovered in caves near the West Bank between 1947 and 1956. They represent some of the oldest surviving biblical manuscripts, written primarily in Hebrew, Aramaic, and Greek. While a related script, Cryptic A, was decoded back in 1955, Cryptic B remained a stubborn puzzle due to its distorted symbols, inconsistent handwriting, and the tiny size of the surviving fragments.

Fragile Fragments and Biblical Revelations

The physical state of the manuscripts presented a huge challenge. Only two texts use this cipher, and many pieces are just a few millimetres across. The leather is cracked, darkened, and frayed, with letters written in inconsistent black ink, showing corrections and double-tracing.

Once deciphered, the fragments revealed familiar biblical themes and phrases. They contain references to Yisrael (Israel), Judah, Jacob, and Elohim (God). The content appears religious, employing biblical idioms and focusing on prophetic judgments and eschatological promises about the end of days, including divine judgment and the coming of a Messiah.

For example, fragment 18 mentions 'the tents of Jacob,' echoing language found in the books of Jeremiah and Malachi. Fragment 21 references 'Elohim' and 'your glory.' The texts also include enigmatic mentions of dates, rulers, and a grave, the details of which do not match any known biblical account.

Why Encode a Simple Message?

The reason for using this complex cipher remains a topic of speculation. Dr Oliveiro suggests the unusual script likely served a symbolic or ritual purpose. By writing in a secret alphabet, the scribes—members of the ancient Qumran sect that lived near the Dead Sea over 2,000 years ago—could indicate the text was intended for a select audience, such as priestly elites. This would enhance the sacred status of the writing without actually hiding its meaning.

The complexity of Cryptic B lies not in a sophisticated cipher, but in the deliberate distortion of Hebrew letter shapes. This clever obfuscation made the texts appear undecipherable for generations, despite containing no hidden mystical messages. This decipherment finally closes a chapter on one of the last great linguistic puzzles from the ancient world, offering fresh insight into the beliefs and practices of the enigmatic Qumran community.
