TUSCON, ARIZONA—Nicholas Reeves, currently at the University of Arizona, was examining ultra-high resolution images of Tutankhamun’s tomb when he noticed fissures and cracks in two places on its walls. He suggests that the cracks reveal the presence of two passages that were blocked and then plastered and painted over. Reeves thinks that one of the passages probably leads to a storeroom, while the other, which aligns with both sides of the tomb’s entrance chamber, may open to a corridor and a queen’s burial chamber. As he told The Economist, such an arrangement is typical of tombs built for Egyptian queens. Reeves adds that Tutankhamun’s tomb is smaller than other kings’ tombs in the Valley of the Kings, and it seemed to have been put together in a hurry. Could this tomb have been intended for Nefertiti, Tutankhamun’s stepmother? Radar scans could reveal hidden rooms if they exist. “Each piece of evidence on its own is not conclusive, but put it all together and it’s hard to avoid my conclusion. If I’m wrong I’m wrong, but if I’m right this is potentially the biggest archaeological discovery ever made,” he said.
