A colleague, showing the height of the so-called air shafts—this one inside the Queen's Chamber looking South, so QC(S). These were clearly at eye-height, but when found were covered over with stone 'plates,' so were evidently not meant to be looked into - at least not by living eyes… the King's ka, on the other hand, could see and pass through stone unhindered… Perhaps his ka was intending to 'dive through the thin coverstone and then follow the shaft. See Khufu's Vision for Akhet Khufu?
Collage of tools found in the Queen's Chamber Northern Shaft. At left is a diorite hammer stone used to carve out softer stone, such as limestone. At right are two views of a curious copper tool, or perhaps a symbol of office, with two curved 'horns,' and a shaft with two rivets. Also found, but now missing, was a length of wood. Copper was rare and valuable at the time. Why were the tools left in the covered shaft? Was this an archtect, or mason, leaving his signature behind? The tools are now in the British Museum.
