The ancient scrolls look like dense bits of black rock, but scientists have figured out a way to virtually unroll them and unlock their secrets.

Scrolls were in Herculaneum

Ancient town was destroyed by volcanic eruption

Rome CNN  — 

For over two millennia, scrolls from the ancient Roman town of Herculaneum eluded analysis. Left buried under the ashes when Mount Vesuvius erupted in 79 AD, the scrolls were preserved – but in a charred and illegible state.

But thanks to modern science, researchers are now able to read what’s on the scrolls without even opening them up.

They’ll do this with a new process that allows them to unroll the Herculaneum scrolls – virtually.

The process is called X-ray phase-contrast tomography. It virtually unwraps the scrolls and flattens out digital sheets of the physical carbonized document.

That’s a major development because the scrolls, which were buried in a Herculaneum library and excavated 260 years ago, are extremely fragile and could potentially be ruined by unwrapping using older, more invasive methods.

The technology could help scientists and others read other ancient scrolls that have been illegible for thousands of years.

“The goal of this technology is to make it accessible to all art historians, museums and libraries to virtually read ancient manuscripts that have been so damaged,” says Alessia Cedola, a researcher and physicist at Italy’s National Research Council.

“The result is significant because we are finally able to virtually see what’s inside the scroll.”

So what do the scrolls say? It’ll be a little while before the world knows.

The content from two of the scrolls – written by the ancient philosopher Philodemus on the subject of political rhetoric – is currently being translated from ancient Greek into English and will soon be published in a scientific journal.

There are hundreds of Herculaneum scrolls, some unrolled and others in a fully rolled state.

The volcanic eruption also devastated the city of Pompeii.
