When Mount Vesuvius erupted in 79 AD, it didn’t just destroy Pompeii. In the nearby luxury seaside town of Herculaneum, a massive villa belonging to Julius Caesar’s father-in-law was buried under a river of volcanic ash. Inside lay a priceless treasure: the only library ever recovered intact from the Greco-Roman world.
For centuries, these hundreds of papyrus scrolls remained unread. The volcanic heat had instantly carbonized them, turning the documents into fragile cylinders of literal charcoal.
Trying to unroll them meant turning them into dust. They were deemed unreadable, lost to time.
Until now. Thanks to an international competition and cutting-edge Artificial Intelligence, scientists have finally begun to read the invisible ink inside these charred scrolls without opening them.
The Herculaneum Scrolls: A Black Hole of Ancient History

When archeologists first discovered the scrolls in the 1750s, they mistook them for lumps of charcoal or briquettes. Once they realized they were looking at written history, a centuries-long tragedy began.
Early attempts to manually unroll the scrolls destroyed dozens of them. The carbonized papyrus was so brittle that it flaked away at the slightest touch. The surviving scrolls were kept in a library in Naples, preserved but completely locked away from human eyes.
Historians knew that if these scrolls could be read, they might rewrite our understanding of ancient philosophy, literature, and politics.
The Vesuvius Challenge: Crowdsourcing the Solution
The breakthrough didn't come from a hidden lab, but from a global contest called the Vesuvius Challenge. Launched by tech entrepreneurs and computer scientists, the competition offered hundreds of thousands of dollars in prizes to anyone who could write code capable of reading the rolled-up scrolls.
First, scientists used advanced X-ray micro-computed tomography (high-resolution CT scans) at a particle accelerator in Europe to scan the scrolls. This created 3D digital volumes of the rolled papyrus.
The problem? The ink used by ancient scribes was made of carbon and water. To an X-ray scanner, carbon-based ink looks exactly like carbon-based charred papyrus. Human eyes couldn't see the letters.
That is where Artificial Intelligence stepped in.
How the AI Cracked the Code

In late 2023, computer science students cracked the mystery using Machine Learning and neural networks.
The AI was trained to look for incredibly subtle, microscopic textures on the papyrus surface—cracks, ripples, and slight changes in thickness where the ink had dried 2,000 years ago.
- Virtual Unwrapping: Algorithms mapped the twisted, distorted 3D layers of the scroll and digitally flattened them out like a sheet of paper.
- Texture Detection: The AI analyzed the flattened surface to spot the "shadows" of the ink that were invisible to the human eye.
- Ink Enhancement: The neural network highlighted these micro-textures, making the ancient Greek letters glow brightly on the computer screen.
In early 2024, the grand prize was awarded when an AI successfully extracted 15 columns of text, revealing more than 2,000 ancient Greek characters.
What Do the Scrolls Say?
The first fully decoded text belongs to a lost work by the Epicurean philosopher Philodemus.
Instead of grand political histories, the scroll contains a beautifully poetic discussion about the pleasures of life. The author contemplates whether scarce goods, like food, bring more pleasure than abundant ones, and muses on how to live a tranquil life.
Scholars estimate that this is just the tip of the iceberg. The villa where the scrolls were found likely holds thousands more documents still buried under the volcanic rock.
A New Era for Archeology
The success of the Vesuvius Challenge means that hundreds of charred scrolls can now be safely read without ever being touched. AI has officially built a bridge to the past, proving that no mystery is truly unsolvable when human curiosity meets advanced machine learning.
