CT scans to "unroll" the scorched papyri from Herculaneum


I am always excited when someone tackles the challenge of trying to unroll the charred scrolls from Piso's library in Herculaneum. Although many scholars think the library mostly contains epicurean works, I keep hoping for copies of lost books written by Piso's son-in-law, Julius Caesar. According to ancient sources, Caesar dabbled in a variety of literary genres including poetry and even a joke book. I think it would be very revealing to discover what Caesar found humorous.

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' [from the Villa of the Papyri in Herculaneum] rolled-up pages. Then, he and his colleagues hope to digitally "unroll" the scrolls on a computer screen so scholars can read them.

Seales admits that there are hurdles, the biggest being the carbon-based ink thought to have been used on the scrolls. He says that since the papyrus in the scrolls was turned to carbon by the fury of Vesuvius, it might be impossible to visually separate the writing from the pages, even with powerful computer programs.

"The open question is, will we be able to read the writing?" Seales said. "There is a chance that we won't be able to do it with our current machine, and that we'll have to re-engineer some things. But if that's the case, that's what we will do." - More: Lexington Herald-Leader
