In a study published today in PLOS ONE, researchers used x-rays to reveal how 3000-year-old paintings inside Egypt’s Theban Necropolis unfolded step by step. The findings hint at the creative process used to produce these ancient masterworks.Applying the x-ray method to ancient Egyptian wall paintings “is really a game changer,” says Marine Cotte, a chemist at the European Synchrotron Radiation Facility, who previously collaborated with...
