Computer scientist to unroll' papyrus scrolls buried by Vesuvius

LEXINGTON, Ky. — On Aug. 24, 79 A.D., Italy's Mount Vesuvius exploded, burying the Roman towns of Herculaneum and Pompeii under tons of super-heated ash, rock and debris in one of the most famous volcanic eruptions in history.

Thousands died. But somehow, hundreds of papyrus scrolls survived — sort of — in a villa at Herculaneum thought to have been owned at one time by Julius Caesar's father-in-law.

The scrolls contained ancient philosophical and learned writings. But they were so badly damaged — literally turned to carbon by the volcanic heat — that they crumbled when scholars first tried to open them centuries later.

The remaining scrolls, stored away in Italy and France, haven't been read — or even unrolled — since 79 AD.

Now, a computer scientist from the University of Kentucky hopes that modern digital technology will allow him to peer inside two of the fragile scrolls — without physically opening them — and unlock secrets they have held for almost 2,000 years.

Brent Seales, the Gill professor of engineering in UK's computer science department, will use an X-Ray CT scanning system to collect interior images of the scrolls' rolled-up pages. Then, he and his colleagues hope to digitally "unroll" the scrolls on a computer screen so scholars can read them.

"It will be a challenge because today these things look more like charcoal briquets than scrolls," Seales said. "But we're using a non-invasive scanning system, based on medical technology, that lets you slice through an object and develop a three-dimensional data set without having to open it, just as you would do a CT scan on a human body."

The two scrolls that Seales and his team will work on are stored at the French National Academy in Paris. The UK group will spend July working there.

Their system was developed at UK through the EDUCE project, or Enhanced Digital Unwrapping for Conservation and Exploration, which Seales launched through a grant from the National Science Foundation.

Experts say that if the UK system works as well as hoped, it could provide a safe new way to decipher and preserve more scrolls from Herculaneum, as well as other ancient books, manuscripts and documents that are too fragile to be opened.
