Narmer

In the New Kingdom king lists, the first king of Egypt is named Meni, who is regarded as the first pharaoh of the unified Kingdom of Egypt. The Greek equivalent is Min, as stated by Herodotus, while Manetho, via Africanus and Eusebius, calls him Menes. However, there is no contemporary archaeological evidence containing the cartouche name of Menes, as cartouches did not begin to be used until the time of the Old Kingdom.
It seems that the practice of placing the nebty names into cartouches was undertaken by scribes due being unable to recognise or locate the corresponding names from the ancient sources. Fittingly, Meni means : He who endures.

The contemporary Horus name of the first king, Narmer, is well attested. It is firmly established that he indeed was the first ruler of the kingdom. The early kings were only known by their Horus name, and there is no evidence that Narmer used any other.
