So far the imaging has revealed some 6,800 hidden pages in 74 of the monastery’s 163 recycled parchments, called palimpsests. “We have identified erased texts in 10 languages that date from the fifth to the 12th centuries,” says Michael Phelps, the director of the recovery effort. In the example above, a text in Syriac overlays a ninth-century translation of a page from a medical treatise by the ancient Greco-Roman physician known as Galen.Bit by bit, a letter at a time, whatever it takes. Until we're done.
With dozens of palimpsests yet to be scanned, Phelps believes there are still treasures to come: “It’s not unlikely that St. Catherine’s holds many more pages of previously unidentified and unstudied texts from antiquity.”
