Scientists Read Burnt Scrolls Using X-Ray Fluorescence

Scientists have developed a novel, non-destructive technique to read text from severely burnt papyrus scrolls, a breakthrough that could unlock invaluable historical information from ancient sites like Herculaneum. The method, detailed in a publication associated with Nature on September 22, 2026, involves using X-ray fluorescence (XRF) to detect the presence of ink without the need to unroll or physically disturb the fragile, carbonized scrolls. This advancement offers a potential solution to deciphering texts that have been rendered illegible by fire, a common fate for ancient documents.

To validate their approach, the research team replicated the conditions of ancient scrolls by intentionally burning papyrus. They then applied XRF, a technique that uses X-rays to excite atoms in a sample, causing them to emit characteristic fluorescent X-rays. These emitted X-rays reveal the elemental composition of the material, and crucially, the presence and distribution of ink. The ink used in ancient times often contained metallic elements, such as lead, which are detectable by XRF. By mapping the locations of these metallic elements, researchers can reconstruct the letters and words written on the papyrus, even when the material itself is too brittle to handle.

The implications of this research are significant, particularly for the study of the Herculaneum papyri. This ancient Roman town was buried under volcanic ash from the eruption of Mount Vesuvius in 79 CE, preserving thousands of papyrus scrolls. However, many of these scrolls are carbonized and extremely fragile, making traditional methods of unrolling and reading them impossible without causing irreparable damage. Previous attempts to read these scrolls have involved laborious and often destructive processes. The new XRF method promises a way to access the content of these unique historical artifacts without further risk.

This development builds upon earlier efforts in digital imaging and computational analysis aimed at deciphering burnt scrolls. However, the XRF technique offers a distinct advantage by directly detecting the ink's composition at a microscopic level. The researchers' successful application of this method to their intentionally burnt papyrus samples demonstrates its viability. The next steps involve applying this technology to the actual Herculaneum scrolls, which could potentially reveal lost philosophical texts, historical accounts, and literary works from the ancient world, offering unprecedented insights into Roman civilization.
