Researchers Recover 42 Lost Pages from 6th-Century New Testament Codex H

Researchers have recovered 42 lost pages from Codex H, one of the world's most important early New Testament manuscripts.

Codex H, or Codex Hierosolymitanus, is a palimpsest. Parts of the manuscript were reused and rewritten over the centuries. Researchers spotted faint mirror-image traces after finding that the manuscript had been re-inked. They then applied multispectral imaging to recover ghost text invisible to the human eye.

The University of Glasgow announced the discovery in an April 24 press release. "The fragments show how 6th-century scribes corrected, annotated and interacted with sacred texts," the university said. The physical state of the manuscript reveals how sacred works were reused and repurposed once they fell into disrepair.

The text dates to the sixth century and copies the Letters of St. Paul. It does not contain new scripture. The manuscript was disassembled in the 13th century at the Megisti Lavra monastery on Mount Athos, Greece. Since then, its pages scattered across European libraries. Only fragments survive, including some at the University of Glasgow.

A team found the lost pages in these fragments. They include ancient chapter lists that "differ drastically from how we divide these letters today," the university said.

Codex H's importance comes from its rarity, said Garrick Allen, a University of Glasgow professor who led the project. "It's an important witness to the text of Paul's Letters in a period where we don't have that many manuscripts," Allen told Fox News Digital. He referred to the sixth to ninth centuries.

Scribes and readers marked up biblical texts for centuries, much as people do today. Codex H preserves over 1,000 years of annotations. "Manuscripts of the New Testament and other literature were often annotated and marked up by scribes and readers," Allen said. "We have recovered [these pages] due to the unintended results of a medieval conservationist."

The manuscript includes over 70 corrections by a scribe who compared it against another copy. It also has annotations from at least 15 later readers. These include prayers, poems, grammatical notes and other information. "These types of notes are not unusual but, because Codex H had such a long life in many forms, its pages attracted many interested readers," Allen said. "These annotations are often the only tangible evidence left that these anonymous people existed."

Allen said the manuscript likely reached the end of its working life, prompting disassembly. "Six hundred to 700 years is a long time for a book to be kept in working order, even though we know that at least one person attempted to conserve it during this period through re-copying," he said. At a remote site like Mount Athos, where parchment was expensive, the monastery reused it for other books.

Breaking it apart helped preserve it. Pages went into other books as binding material and flyleaves, then spread across European collections. "The book was re-inked in its entirety at some point in its working life, meaning that someone rewrote over the existing text ... in an attempt to keep the book usable for a new generation," Allen said. "Eventually, the book was disbound and reused as binding material and flyleaves when librarians at the Megisti Lavra monastery on Mount Athos repaired other books in their collection. It's this repurposing of this ancient book that led to its continued existence."

The most surprising part was reading biblical texts that no longer exist, Allen said. "We have recovered [these pages] only due to the unintended results of a medieval conservationist," he added. "This process makes me optimistic that many ancient manuscripts still have much more to tell us about the people who made and used them."

Advances in imaging technology drive such progress. "Although each manuscript is by definition unique and presents its own challenges, we think that we've developed a model for working with challenging manuscripts like palimpsests at a larger scale," Allen said. "When manuscript and biblical scholars work closely with imaging specialists, data scientists, monastic communities, museums, and other local partners, we can really make progress in our understanding of these important documents."
