The secret hidden in these ancient manuscripts isn’t written in ink

Ancient parchment manuscripts, made from animal skin, hold more secrets than just the words inscribed on their surface. Scientists have now devised a technique to extract genetic material from these historical documents without causing any damage. This breakthrough, detailed in a paper published in Manuscript Studies, could provide valuable insights into various aspects of life stretching back approximately 1,300 years.

The parchment, a material used for centuries across Europe, the Middle East, and parts of Africa, often contained genetic clues alongside the written text. Tim Stinson, an associate professor of English at North Carolina State University, explains that analyzing this genetic information can help answer questions about the creation and journey of individual manuscripts.

Moreover, the genetic material from parchments can reveal broader stories. Matthew Breen, co-author and an expert in veterinary genetics, notes that studying these ancient DNA samples could shed light on the evolution of farm animals, the development of different breeds, and livestock diseases over time.

Historically, access to such manuscripts has been a major hurdle for researchers due to concerns about damaging rare and culturally significant artifacts. However, the new technique, which involves gently rubbing the parchment with a dry cytology brush similar to those used for Pap smears, has shown to be successful. This method allows researchers to collect cellular material without harming the manuscripts.

The team demonstrated this approach by sampling 91 manuscripts from the Rubenstein Library at Duke University, ranging from the late eighth to early 20th centuries. The process is surprisingly straightforward and requires minimal intervention, preserving the integrity of the documents.

By utilizing state-of-the-art next-generation sequencing technologies, researchers can extract and amplify genetic sequences from the collected cells. This scientific approach not only preserves the historical value of the manuscripts but also opens up new avenues for interdisciplinary research, combining genetics with historical, archaeological, and other scholarly inquiries.

The researchers are optimistic about the potential of this field, seeking funding to further explore the vast, untapped sources of information locked within historic parchment manuscripts. This pioneering work could revolutionize how we understand the past, bridging the gap between genetics and the historical record.
