The Design of the Step Pyramid
Imhotep designed and built the Step Pyramid at Saqqara for the pharaoh Djoser, changing the earlier tradition of the flat mastaba tomb, and by stacking successively smaller stone platforms one atop another created the first large all-stone monumental building in human history; this breakthrough in architectural concept laid the technical and aesthetic foundation for the more grand tombs such as the three great pyramids of Giza.
From Mortal to God
About two thousand years after Imhotep’s death, the ancient Egyptians gradually deified him, honoring him as a god of medicine and healing, building temples specially for him at Memphis and elsewhere where the faithful worshiped and sought healing — this process of "a mortal posthumously granted divinity for outstanding talent" was exceedingly rare in the whole of ancient Egyptian history, testimony to the far-reaching impression his achievements in architecture and medicine left on later ages.
