Imaging Recovers 42 Lost Pages of a 6th-Century Saint Paul Manuscript

Scholars have recovered 42 pages that vanished from one of the oldest surviving manuscripts of the New Testament, in a discovery announced in late April 2026 by an international team led by the University of Glasgow. The pages belong to Codex H, also known as GA 015, a sixth-century Greek manuscript of the Letters of Saint Paul long considered a key witness to how the early Christian text was copied and read.

The manuscript had been broken apart in the thirteenth century by monks at the Great Lavra Monastery on Mount Athos, who reused its parchment to bind other books at a time when writing material was scarce and precious. Scattered and partly erased, dozens of its pages were thought lost for good. Working with the Early Manuscripts Electronic Library, the researchers turned to multispectral imaging, photographing the surviving leaves under many different wavelengths of light to reveal traces invisible to the naked eye.

“The pages belong to Codex H, also known as GA 015, a sixth-century Greek manuscript of the Letters of Saint Paul long considered a key witness to how the early Christian text was copied and read.”

The technique exploited a quiet accident of history. When the original pages were re-inked during the Middle Ages, the fresh ink left faint mirror impressions on adjacent sheets. By capturing and computationally enhancing those ghostly traces, the team reconstructed text that had been unreadable for centuries, revealing early chapter divisions and the Euthalian apparatus, a system of notes and cross-references used by early Christian communities to navigate the scriptures.

Rather than uncovering unknown passages, the recovered material illuminates how the New Testament was organized, annotated, and studied in late antiquity. Crucially, the team did not lock the results away. They published an open-access digital edition available to scholars and the public alike, with a printed volume to follow, ensuring that anyone can examine the rescued pages. The achievement is a reminder that even texts thought irretrievably lost can be coaxed back into the light, expanding humanity's shared library and deepening our understanding of how some of the world's most influential writings were carried across the centuries.
