Not sure, but I think these are credit to German artist Gabriel Nagypál upon a videogame they were developing around the aughts.

In any case, the original Giza-area pyramids were absolutely spectacular, IMO. We moderns see basically thousands-year old rubble and make judgements upon all that.
Au contraire, those suckers were absolutely unreal for the time. Truth. Facts & reality.
A just finished pyramid must have been an absolute sight to behold. Wish I could see back through time sometimes just to see things like that!
Is there a VR ancient Egypt?
