The charred lump of scroll sat in an archaeologist’s office, impossible to read without destroying it – until now

The discovery was announced in an article in Science Advances written by researchers from Kentucky and Jerusalem. It described how the researchers used a tool called “virtual unwrapping”, which provides a 3D digital analysis of an X-ray scan.
Last year, Yosef Porath, the archaeologist who excavated at Ein Gedi in 1970, walked into the Israel Antiquities Authority’s Dead Sea Scrolls preservation lab in Jerusalem with boxes of the charcoal chunks. The lab has been creating hi-resolution images of the Dead Sea Scrolls, the earliest copies of biblical texts ever discovered, and he asked researchers to scan the burned scrolls. “I looked at him and said, ‘you must be joking,”‘ said Shor, who heads the lab. She agreed, and a number of burned scrolls were scanned using X-ray-based micro-computed tomography, a 3D version of the CT scans hospitals use to create images of internal body parts. The images were then sent to William Brent Seales, a researcher in the computer science department of the University of Kentucky. Only one of the scrolls could be deciphered.
Using the “virtual unwrapping” technology, he and his team painstakingly captured the three-dimensional shape of the scroll’s layers, using a digital triangulated surface mesh to make a virtual rendering of the parts they suspected contained text. They then searched for pixels that could signify ink made with a dense material like iron or lead. The researchers then used computer modeling to virtually flatten the scroll, to be able to read a few columns of text inside. “Not only were you seeing writing, but it was readable,” said Seales. “At that point we were absolutely jubilant.” The researchers say it is the first time a biblical scroll has been discovered in an ancient synagogue’s holy ark, where it would have been stored for prayers, and not in desert caves like the Dead Sea Scrolls.
The discovery holds great significance for scholars’ understanding of the development of the Hebrew Bible, researchers say. In ancient times, many versions of the Hebrew Bible circulated. The Dead Sea Scrolls, dating to as early as the 3rd century B.C., featured versions of the text that are radically different than today’s Hebrew Bible. Scholars have believed the Hebrew Bible in its standard form first came about some 2,000 years ago, but never had physical proof, until now, according to the study. Previously the oldest known fragments of the modern biblical text dated back to the 8th century.
The text discovered in the charred Ein Gedi scroll is “100 percent identical” to the version of the Book of Leviticus that has been in use for centuries, said Dead Sea Scroll scholar Emmanuel Tov from the Hebrew University of Jerusalem, who participated in the study. “This is quite amazing for us,” he said. “In 2,000 years, this text has not changed.” Noam Mizrahi, a Dead Sea Scrolls expert at Tel Aviv University who did not participate in the study, called it a “very, very nice find.” He said the imaging technology holds great potential for more readings of unopened Dead Sea Scrolls. “It’s not only what was found, but the promise of what else it can uncover, which is what will turn this into an exciting discovery,” Mizrahi said.
