Hi Khazar-Khum

Also if you consider that even as late as Piazzi Smyth he wrongly had the vertical axis aligned with the south wall of the QC. Then it is unlikely these early Masters would have exact knowledge about the interior layout of the GP. Therefore Poussin would not be able to incorporate an unknown GP design in his artwork. Where did Poussin and other early artists get their lengths and angle measures?

It is doubtful that anyone beyond the 4th or maybe early 5th dynasty would even know about the QC shafts or the KC shaft angles or the relieving chambers above the KC.
