X-rays uncover hidden faces in Rembrandt painting
Lead paint under the surface gives away artist’s indecisiveness

HIDDEN LAYERS Using intense X-ray beams, scientists discovered three other locations that Rembrandt considered placing the servant (the character without a hat) in his 1662 painting “Syndics of the Drapers’ Guild.” Two of the hidden faces were found on the right edge of the painting, and the other was between the two right-side drapers.
