In July 2018, German-Egyptian researchers’ team head by Ramadan Badry Hussein of the University of Tübingen reported the discovery of an extremely rare gilded burial mask that probably dates from the Saite-Persian period in a partly damaged wooden coffin in Saqqara. The last time a similar mask was found was in 1939. The eyes were covered with obsidian, calcite, and black hued gemstone possibly onyx. "The finding of this mask could be called a sensation. Very few masks of precious metal have been preserved to the present day, because the tombs of most Ancient Egyptian dignitaries were looted in ancient times." said Hussein.
