Pyramid of Djoser
Imhotep was one of the chief officials of the Pharaoh Djoser. Concurring with much later legends, egyptologists credit him with the design and construction of the Pyramid of Djoser, a step pyramid at Saqqara built during the 3rd Dynasty. He may also have been responsible for the first known use of stone columns to support a building. Despite these later attestations, the pharaonic Egyptians themselves never credited Imhotep as the designer of the stepped pyramid, nor with the invention of stone architecture.
