Scholars Recover 42 Lost Pages of a 6th-Century New Testament Manuscript in Breakthrough Study

GLASGOW — In a discovery that scholars are calling “monumental,” an international team of researchers has recovered 42 previously lost pages from one of the world’s most significant New Testament manuscripts, shedding new light on the early transmission of Christian scripture.

The manuscript, known as Codex H (GA 015), is a 6th-century Greek text containing the Epistles of St. Paul. The findings were announced on April 24, 2026, by the University of Glasgow, where the project was led by Professor Garrick Allen.

Long believed to be fragmentary, Codex H had undergone a remarkable transformation over the centuries. Between the 10th and 13th centuries, monks at the Great Lavra Monastery on Mount Athos in Greece dismantled the manuscript, repurposing its parchment pages as binding material and protective leaves for other books — a common practice in the medieval world, when writing materials were scarce.

As a result, pieces of the manuscript were scattered across libraries in Italy, Greece, Russia, Ukraine and France. Their existence was first systematically traced in the 18th century by a French monk, but much of the original text remained hidden — until now.

The breakthrough came through the use of multispectral imaging, an advanced technique that captures traces of ink invisible to the naked eye. When the manuscript was overwritten centuries ago, the newer ink left behind faint “ghost impressions” on adjacent pages. By analyzing these residual marks, researchers were able to reconstruct text that had effectively vanished.

To verify the manuscript’s age, the team conducted radiocarbon dating in Paris, confirming that the parchment dates to the 6th century.

“Codex H is a crucial witness to our understanding of the Christian Bible,” Professor Allen said in a university statement. “To uncover this much new evidence about its original form is truly extraordinary.”

Beyond recovering portions of the Pauline epistles, the newly revealed pages offer rare insight into early scribal practices. Among the most significant findings is what scholars believe to be the earliest known example of the Euthalian apparatus — a system of chapter lists, prologues and marginal markers designed to guide readers through the text before the advent of modern pagination.

These chapter divisions differ markedly from those used today, suggesting that early Christian communities navigated scripture in ways that have since evolved. The pages also contain corrections and annotations, evidence of active engagement by scribes and readers.

The study further illuminates the medieval culture of manuscript reuse, highlighting how texts were dismantled and repurposed in response to material scarcity.

Funded by the Templeton Religion Trust and the U.K.’s Arts and Humanities Research Council, the project was carried out with the support of the Great Lavra Monastery. A digital edition of Codex H is now freely available online, while a printed critical edition is in preparation.

For scholars of early Christianity, the discovery represents a significant advance in textual criticism — the discipline devoted to reconstructing ancient texts. Each recovered page, researchers say, deepens not only our understanding of the scripture itself, but also of the generations who preserved it across more than 1,500 years. []
