Yeah, my bad. Strike out the 'Djoser' responsibility and insert 'Sneferu'.
The next part to this was the differences between the pyramids, from a basic mastaba-on-steroids with below ground chambers, to galleries, vaulted ceilings, and so far just one with 'shafts'. I know we are all aware of what pyramids look like, and how different many of them are when compared to each other. I know that there are some great references and records that define whom is responsible for each of them. And I know we can look at the construction styles, materials, and craftsmanship that appears to have gone into them. While much can be said about Imhotep being a wonder in his profession, more might be said about his elevation to god-like status because of his design of Djoser's pyramid as being something akin to recreating something that could only be defined as built by the Gods...that had existed previously, and was up until Imhotep unrepeatable.
Once it can be done again, and due to 'ownership', any Pharaoh can make the claim of 'this is mine', and who would dare argue? Well...unless arguments extended to defacing references that meant a little more than giving someone the finger, and more about stating that someone did in fact not own something.
For the Great Pyramid, the feature above the entrance identifies something that was not recreated in any form throughout any of the other pyramids, and more than likely because it was covered over and hidden until such a time as removal of the blocks revealed it. That it shows three definite forms means the intention was already there concerning what would be upon the plateau, and yet those three pyramids are different, when one would think appreciation for such perfection in the Great Pyramid would be continued in the other two. If we were to look at features that we are aware of, the order upon the plateau would be Khafre, Menkaure, then Khufu, improving in style at each step. Unless some other reality is clouded to us.
Despite the best observations made by professionals in their fields of work, I cannot help but imagine that Khufu's pyramid was built first and foremost of all of them up and down the Nile, and is represented by the small pyramid-form within the feature above the entrance...an extension of what the two mounds in that feature started.
And why do I say this?
Because Imhotep got more fame...for stacking mastabas. Because Sneferu built four pyramids. But mostly...because the Cult of Khufu continued until the sixth/seventh century CE when Sirius reached its highest culmination. Whatever was inside the Great Pyramid was not known about in Djoser's time but was in Sneferu's time, and more-so, it was mostly deciphered by Khufu's time, leading to repairs upon that pyramid and adoption by Khufu.
For such a supposedly bad man, his cult sure lasted a long time. Unless some deeper meaning to Khufu's followers has been hidden all along, and they didn't dissolve but rather just changed their tune.
