EN: If I could comment on your association with the Old Kingdom, it is also quite logical for the Old Kingdom to have inherited ideas from an earlier period. If Giza is earlier, then concepts associated with Giza would also have been inherited into the Old Kingdom.
SC: This makes logical sense. However, what I think is missing here is knowledge of the nature of the glyphs in these inaccessible areas of the relieving chambers opened by Vyse. As I understand it, the glyphs within these crevices and between the block joints are typical Old Kingdom glyphs. Question is - how old are Old Kingdom glyphs? What is the oldest Old Kingdom glyph we have reliably dated? And what type of writing preceded such? If the evolution of AE writing can be reasonably dated then the glyphs between the cracks can also be reasonably dated.
(PS - I believe there were two forms of AE writing found in these chambers, one I believe is older than the other.
