Jan Bartek – AncientPages.com – An international team of scholars, led by Professor Garrick Allen at the University of Glasgow, has recovered 42 previously lost pages from Codex H, one of the world’s most important early New Testament manuscripts.
Using advanced imaging techniques, the researchers revealed text that had been erased centuries earlier. This discovery offers new insights into how biblical texts were copied, preserved, and reused during the Middle Ages, providing valuable information about the transmission and adaptation of scripture over time.

This manuscript—a 6th-century copy of the Letters of St Paul—disappeared from view when it was taken apart at the Great Lavra Monastery on Mount Athos, Greece, in the 13th century. Its pages were re-inked and repurposed as binding material and flyleaves for other manuscripts, a common but, in hindsight, poignant practice.
Now, centuries later, the surviving fragments of Codex H are dispersed across libraries in Italy, Greece, Russia, Ukraine, and France.
Professor Garrick Allen explains the process that led to the discovery: “The breakthrough came from an important starting point: we knew that at one point, the manuscript was re-inked. The chemicals in the new ink caused ‘offset’ damage to facing pages, essentially creating a mirror image of the text on the opposite leaf – sometimes leaving traces several pages deep, barely visible to the naked eye but very clear with latest imaging techniques.
“In partnership with the Early Manuscripts Electronic Library (EMEL), researchers used multispectral imaging to process images of the extant pages, in order to recover ‘ghost’ text that no longer physically exists, effectively retrieving multiple pages of information from every single physical page. To ensure historical accuracy, the team also collaborated with experts in Paris to perform radiocarbon dating, confirming the parchment’s 6th-century origin.”

While the recovered text includes familiar sections from Paul’s Letters, its significance lies in the historical and cultural context it reveals. The discovery provides fresh evidence of how the New Testament has changed, been transmitted, and been interpreted over the centuries. It also offers new information about the individuals who produced and used the manuscript, how people engaged with their sacred writings in daily life, and how books were repurposed or recycled once they became worn or damaged.
Professor Allen continues: “Given that Codex H is such an important witness to our understanding of Christian scripture, to have discovered any new evidence – let alone this quantity – of what it originally looked like is nothing short of monumental.”
Key findings include:
- Ancient chapter lists. The pages contain the earliest known examples of chapter lists for Paul’s Letters, which differ drastically from how we divide these letters today.
- Scribal insights: The fragments show how 6th-century scribes corrected, annotated and interacted with sacred texts.
- Medieval recycling: The physical state of the manuscript reveals how sacred works were reused and repurposed once they fell into disrepair.

This project was made possible through funding from Templeton Religion Trust and the Arts and Humanities Research Council (UK), with the cooperation of the Great Lavra Monastery.
A new print edition of Codex H is forthcoming and a digital edition is freely available at https://codexh.arts.gla.ac.uk/, making these recovered pages available to the public and scholars for the first time in centuries.
