Progress in reading the Herculaneum scrolls

TECHNOLOGY WATCH: Words emerge from ancient scrolls charred during eruption of Vesuvius. Powerful x-ray technique reveals letters and words on two fire-damaged scrolls from Herculaneum and provides clues to the author of one (Ian Sample, The Guardian). For some time I have been following efforts to recover the text of the carbonized scrolls from Herculaneum. The latest media reports seem to indicate that there has been a little progress.
Scientists at the National Research Council in Naples found they could read some of the scrolls without opening them by peering inside with x-rays. The procedure they developed, called x-ray phase contrast tomography (XPCT), could pick out the black ink against the charred papyrus sheet because of a tiny but distinct difference in the way the two materials refracted the x-rays.

Using XPCT, Vito Mocella and others revealed letters from the Greek alphabet and several distinctive words on two fire-damaged scrolls, one rolled, the other unrolled. The scrolls had been handed to Napoleon Bonaparte as a gift in 1802 and now belong to the Institute of France.

X-ray images taken of the unrolled scroll identified two words written in a hidden layer of the payrus. On one line, the researchers spotted Greek capital letters spelling out a word meaning “would fall”. On the next line, they found another Greek word meaning “would say”.

The rolled-up scroll was badly damaged and flattened from the blast of the eruption, making it tougher to read out the words on the papyrus. But Mocella said they could make out several letters from incomplete words. Some letters might have spelt out Greek words meaning “to deny” or “for”, with other letters resembling the word for “the”.

The images produced by the x-ray machine gave the scientists rare clues to the author of the scrolls. On close inspection, they found that the handwriting style of the rolled-up scroll was similar to that of another Herculaneum papyrus written by the Epicurean philosopher Philodemus, who may have written the text in the first century BC.
As I have said before, non-destructive and non-invasive scanning technologies are the way of the future. Bit by bit, a letter at a time, whatever it takes. Until we're done.
