1,300 Years of History Preserved in Ancient Parchments

From Archaeology News:

The study appeared in the journal Manuscript Studies. Researchers examined 91 parchment manuscripts preserved at Duke University’s David M. Rubenstein Rare Book & Manuscript Library. The collection included religious texts, scrolls, legal records, fragments, and manuscripts written in several languages. The documents came from England, different parts of Europe, the Middle East, and northeastern Africa.

For more than a thousand years, parchment served as the main writing material across Europe and much of the Mediterranean region. Unlike paper, parchment came from animal hides, usually sheep, goats, or cattle. Millions of parchment documents still survive in libraries and museums today. Researchers involved in the study describe those collections as a large biological archive preserved across centuries.

Scientists faced a major obstacle for years. Traditional ancient DNA studies often require researchers to cut, scrape, or drill into material samples. Archivists and conservation experts rarely allow such methods on rare manuscripts because even small damage matters when dealing with cultural heritage objects.

The team used a different technique. Researchers gently rubbed the parchment with small cytology brushes, the same type often used in medical testing. The brushes collected tiny traces of cells from the surface without leaving visible damage.

After sampling, scientists extracted DNA from the brushes and analyzed the material with next-generation sequencing technology. These sequencing methods work well with old and fragmented DNA, which often survives in poor condition inside ancient material. (Read more.)
