Lead Ink: Key to Unlocking Burnt Scrolls?
22 Sep
Summary
- X-ray technology combined with AI can now 'virtually unroll' ancient charred papyri.
- Lead in ancient ink significantly improves X-ray detection of hidden text.
- A new study recreates scrolls to test lead's effectiveness in deciphering.
Hundreds of papyrus scrolls, carbonized by the AD 79 eruption of Mount Vesuvius, remain unread in Naples' National Library. These Herculaneum scrolls are too fragile to unroll physically.
Researchers are now employing X-ray technology and artificial intelligence to 'virtually unroll' these ancient texts. A new study published in PLOS One reveals that X-ray imaging can more effectively detect ink containing lead, a component found in some of the scrolls.
By recreating charred scrolls with lead-infused ink, scientists demonstrated that lead significantly enhances AI's ability to identify text in X-ray scans. This breakthrough offers a promising method to identify which of the 600-plus unopened scrolls are best candidates for non-invasive deciphering.
This advancement builds upon earlier discoveries, including the Vesuvius Challenge, which incentivizes scroll decoding. The findings suggest a path forward for reading even the most damaged and challenging Herculaneum scrolls, potentially revealing lost ancient knowledge.
