A Scroll Rated "Zero for Readability" Gave Up Nearly 2,000 Years of Secrets

In the 1980s, researchers cracked open a scroll that had been sealed since Mount Vesuvius buried Herculaneum in 79 C.E. They found nothing legible. They gave it a readability score of zero and put it back in storage. It stayed there for decades, correctly labeled as a problem they couldn't solve yet.

A team using AI and high-resolution CT scanning has now announced they read nearly 4.9 feet (1.5 meters) of continuous text from that same scroll, untouched for nearly 2,000 years, across 22 columns of ancient Greek. Nobody physically opened it. The team scanned it with high-resolution X-rays, reconstructed the wound sheet inside the volume, flattened it into a readable surface and used machine learning to bring out faint traces of ancient ink.

This is the first Herculaneum scroll ever read completely from end to end. The text appears to be a Stoic philosophical treatise that may be attributable to Chrysippus, one of antiquity's most influential thinkers, whose writing is almost entirely lost. Two other scrolls from the same library also produced new text, including the title of a previously unknown philosophical work.

More than 600 unopened Herculaneum scrolls remain, most from the Villa of the Papyri, thought to have belonged to Julius Caesar's father-in-law. The same methods offer a path to reading many more without touching them.

The scroll got a zero. The zero was wrong.

Hot Take: Chrysippus spent his career writing the definitive guide to enduring adversity with dignity. It took a readability score of zero and forty years in a storage cabinet to prove he had a point.
