 This shrine is also cited in the annals preserved on the Palermo Stone, and beginning from the reign of Menkaura, we know the names of the high priests of Memphis that seem to work in pairs at least until the reign of Teti.The architecture of this period was similar to that seen at Giza, royal necropolis of the Fourth dynasty, where recent excavations have revealed that the essential focus of the kingdom at that time centred on the construction of the royal tomb.A strong suggestion of this notion is the etymology of the name of the city itself, which matched that of the pyramid of Pepi I of the 6th dynasty.
