Then the god of the age changed when they started using sandstone ... and carving in sandstone ...
And I believe this came from the Translation of the Famine Steele on Elephantine .. in:
Book: Why the pharaohs built the Pyramids with fake stones
by: Joseph Davidovits
And from my perspective he did a better job on this translation than some other things I have read by people who are deep into things Egyptian!!! He did a great job, imo.
I believe it was also in this book that he said that he could determine the use of 10 separate sizes of forms in the blocks of the GP, and that they repeated in certain patterns.
Since I have wanted to do an animation of different Egyptian work gangs hauling up the baskets of smashed rocks, and the fellows stamping them to mushy aggregate in the forms .. way up in the air ... with the Nile running not too far away below (and likely some water diversion project, as well) ...
Beware the Adze!
Beware the land it came from.

With which he opened the mouths of the gods.
