Although the king list is not organized in dynasties–which were invented by Manetho–the Egyptologist Jaromir Malek explains that "the criterion for such divisions in the Turin Canon invariably was the change of location of the capital and royal residence." Malek thus suggests that the capital of Egypt, then known as Inbu-Hedj, was indeed supplanted at the time by settlements located to the South, East of South Saqqara, where Unas' palace may have been located. In the second millennium BC these cities finally merged and gave rise to Memphis.
