According to ancient Egyptian legends, it was Imhotep (his name can be translated as “he who comes in peace”), who invented building in stone at the beginning of the Third Dynasty (around 2650 BC). This corresponds with the spreading of monumental stone architecture during the reign of Khasekhemwy, the last king of the Second Dynasty, who was Djoser’s predecessor on the throne and his father. The Egyptians themselves had drawn a bolt division line between the Second and Third Dynasty. Based on what we know about Egypt at this time, there is every reason to believe that this perspective was justified. The era of King Djoser and notably of Imhotep marked a completely new period, which can be characterised by an incredible rise in the complexity of the Old Kingdom state and the beginning of construction of the monumental pyramids.
