Researchers Read Sealed 4,000-Year-Old Assyrian Tablets
A portable CT scanner enables historians to digitize ancient internal inscriptions without destroying fragile clay envelopes.
Updated on Sept. 19, 2026 in Botany
Scientists have successfully imaged the contents of a 4,000-year-old Assyrian letter without breaking its protective clay envelope. The research utilized a custom portable high-definition CT scanner to examine the ancient documents.
Why it matters
The development allows scholars to access historical loan records and correspondence that were historically sealed to ensure document integrity. By bypassing the need to break these envelopes, researchers can preserve the original artifacts while retrieving long-hidden information.
Researchers used the ENCI (Extracting Non-destructively Cuneiform Inscriptions) scanner to record 64 tomograms of 48 tablets. The device performs high-definition computed tomography by capturing internal cross-sections of the clay objects.
The players
Museum of Anatolian Civilizations
An archaeological institution in Ankara housing extensive collections of Neolithic to Hittite-era artifacts.
Louvre Museum
A Paris-based research and exhibition institution that serves as a global hub for the conservation of antiquities.
The details
The ENCI system uses computed tomography — a process that uses X-rays to create cross-sectional images of an object's interior. Because the scanner is modular, it was disassembled for transport to museums, where it reconstructs the internal structure of clay envelopes. This method allowed the identification of a 4,000-year-old barley seed inside one envelope, revealing contents previously inaccessible without mechanical breakage.
Timeline
The Assyrian merchant letter was penned 4,000 years ago.
The ENCI device was first tested at the Louvre in 2024.
The Tech Race
This development challenges the historical necessity of breaking clay envelopes to verify ancient loan documents. It aligns with broader efforts in digital archaeology to use portable imaging to bypass the physical destruction of cultural heritage artifacts.
The technology is currently restricted to academic and museum use for the conservation of ancient artifacts. It enables future public exhibitions of fully preserved historical envelopes that were previously kept closed.
The takeaway
The success of the ENCI scanner demonstrates a path toward reading sealed ancient documents without compromising their structural history. Scholars and history enthusiasts should monitor future publications from the Museum of Anatolian Civilizations for the full contents of these scanned tablets.
