There are arguments about the date of the Palermo Stone and of the Royal Annals it records. Historians do not agree if the writing was done in one go or was added to over time. There is no agreement about the date of the writing; was it written about the times it describes, or was it written much later? It has been argued that the stele was made much later, perhaps in the Twenty-Fifth Dynasty (747-656 BCE). It seems clear from the details that, even if the Royal Annals, on the Palermo Stone and other pieces, were not written soon after the time they describe, they are based on an Old Kingdom original.
