The footage captured by Trevor Grassi shows dozens of square shafts carved into bedrock, many extending deep underground but primarily filled with sand, raising new questions about what may lie beneath the surface.
The corrective fluid analysed using light infrared photography revealed a mixture of huntite and calcite, while images made using a 3D digital microscope show that there also are flecks of yellow orpiment, probably to make it blend in better with the fresh papyrus, which would have originally been pale cream in colour.
The coffins are elaborately painted in vivid polychrome. They were stacked in layers and carefully arranged so the 22 coffins fit into the constricted space. They were placed in 10 horizontal rows and the lids separated from the body of the coffin to maximize the limited space. There are no personal names on most of the coffins, but there are titles. The most common title found in the coffin is Singer of Amun or Chantress of Amun.
More than 200 scans from multiple satellites, including Italy's Cosmo-SkyMed and the US-based Capella Space, showed uniform results suggesting massive pillars about 65 feet in diameter wrapped in spirals and plunging nearly 4,000 feet deep. Those pillars appear to end in 260-foot cubic chambers beneath all three pyramids and the Sphinx, which Biondi described as 'huge chambers' measuring roughly 260 feet in length and width.
