Narmer and Menes
The almost complete absence of any mention of Menes in the archaeological record, and the comparative wealth of evidence of Narmer, a protodynastic figure credited by posterity and in the archaeological record with a firm claim to the unification of Upper and Lower Egypt, has given rise to a theory identifying Menes with Narmer.
The chief archaeological reference to Menes is an ivory label from Naqada which shows the royal Horus-name Aha (the pharaoh Hor-Aha) next to a building, within which is the royal nebty-name mn, generally taken to be Menes. From this, various theories on the nature of the building (a funerary booth or a shrine), the meaning of the word mn (a name or the verb endures) and the relationship between Hor-Aha and Menes (as one person or as successive pharaohs) have arisen.
The Turin and Abydos king lists, generally accepted to be correct, list the nebty-names of the pharaohs, not their Horus-names, and are vital to the potential reconciliation of the various records: the nebty-names of the king lists, the Horus-names of the archaeological record and the number of pharaohs in Dynasty I according to Manetho and other historical sources.
Petrie first attempted this task, associating Iti with Djer as the third pharaoh of Dynasty I, Teti (Turin) (or another Iti (Abydos)) with Hor-Aha as second pharaoh, and Menes (a nebty-name) with Narmer (a Horus-name) as first pharaoh of Dynasty I. Lloyd (1994) finds this succession "extremely probable", and Cervelló-Autuori (2003) categorically states that "Menes is Narmer and the First Dynasty begins with him". However, Seidlmayer (2004) states that it is "a fairly safe inference" that Menes was Hor-Aha.
