Ancient Egyptian painters produced some of the most recognizable art of ancient times. Yet, even for their exactitude and memorable iconography, they sometimes made an oops and had to paint a do-over, according to a new study that scanned ancient paintings using X-ray imaging.
The paper by researchers from France, Belgium, Egypt and the U.S. aimed a macro X-ray fluorescence imaging (XRF) machine at two paintings to analyze revisions made to them and what they mean.
