The Egyptians loved to keep written records; papyri and ostraca include everything from grocery lists to love letters yet no one seems to have thought building the biggest structure on earth important enough to deserve documentation. This absence suggests to me that their religion somehow convinced them that it was bad juju for the king to leave a record of how his tomb was built.

IF boiled down, could other than intended spectacle, pyramid were large safes; to hold the contents indefinitely? That scant records exist is part of that security.
A big old Mosler safe is for sale on craigslist, one of those double door bank grade +5,000 pound beauties. It's in good cosmetic condition but size reduces customer interest. 3 years ago it was $4,500, the average going rate. Last week the owner who knew the combination, passed away.
