When Mount Vesuvius erupted in AD79 it destroyed the towns of Pompeii and Herculaneum, their inhabitants and their prized possessions – among them a fine library of scrolls that were carbonised by the searing heat of ash and gas. But scientists say there may still be hope that the fragile documents can once more be read thanks to an innovative approach involving high-energy x-rays and artificial intelligence.

“Although you can see on every flake of papyrus that there is writing, to open it up would require that papyrus to be really limber and flexible – and it is not any more,” said Prof Brent Seales, chair of computer science at the University of Kentucky, who is leading the research.
