The article by Gabriele Barbati focuses on the scientific efforts to study and preserve ancient manuscripts housed at Saint Catherine's Monastery in Egypt's Sinai Peninsula. The monastery, dating back to the 6th century C.E., is home to the world's oldest continuously operating library, containing over 3,000 manuscripts and 13,000 books in various languages. Scholars and scientists have used modern satellite technology to image and study these parchments, uncovering palimpsests—manuscripts with layers of overwritten text. Notable discoveries include works by the Greek physician Galen and the mathematician Archimedes. The article details the use of multispectral imaging and X-Ray Fluorescence to reveal texts that were previously thought to be lost. The findings have significant implications for the history of medicine and science. The article also touches on the challenges faced by the researchers, including political instability in the region.
