Nearly half a century ago, archaeologists found a charred ancient scroll in the ark of a synagogue on the western shore of the Dead Sea.

The lump of carbonized parchment could not be opened or read. Its curators did nothing but conserve it, hoping that new technology might one day emerge to make the scroll legible.

Just such a technology has now been perfected by computer scientists at theUniversity of Kentucky. Working with biblical scholars in Jerusalem, they have used a computer to unfurl a digital image of the scroll.

It turns out to hold a fragment identical to the Masoretic text of the Hebrew Bible and, at nearly 2,000 years old, is the earliest instance of the text.

The writing retrieved by the computer from the digital image of the unopened scroll is amazingly clear and legible, in contrast to the scroll’s blackened and beaten-up exterior. “Never in our wildest dreams did we think anything would come of it,” said Pnina Shor, the head of the Dead Sea Scrolls Project at the Israel Antiquities Authority.

Scholars say this remarkable new technique may make it possible to read other scrolls too brittle to be unrolled.

The scroll’s content, the first two chapters of the Book of Leviticus, has consonants — early Hebrew texts didn’t specify vowels — that are identical to those of the Masoretic text, the authoritative version of the Hebrew Bible and the one often used as the basis for translations of the Old Testament in Protestant Bibles.
