Enter portrait mummies, an art form introduced to Egypt by Romans during the 3rd and 4th centuries B.C. Instead of being entombed in sarcophagi decorated with symbolic images, the dead had realistic paintings, created on wooden panels, placed over their faces and within their wrappings. As some of the earliest portraits ever painted, they're a window into long-gone lives.
They're also an opportunity for scientists, archaeologists and art historians. "Paint the Eyes Softer: Mummy Portraits From Roman Egypt," an exhibition at Northwestern University's Block Museum of Art, combines all three disciplines with a look at the science behind the preserved bodies and portraits.
The free exhibition has plenty of portraits to explore but also delves into the scientific mysteries of the mummies. Intact mummy portraits are very rare, and in November the university took one of its specimens to the nearby Argonne National Laboratory for an X-ray experiment that revealed information about the workshop that probably did the painting and about the materials inside the mummy.
