The glimpses of light into the prehistoric stages of Egyptian civilization prior to Menes are few and far between. We are told that before the consolidation of the Empire by Menes, Egypt was divided into a number of separate nomes or provinces, each gathered about its own independent city and temple, and ruled by the Horsheshu or servants of Horus, who were apparently the chief priests of the respective temples, combining with the character of priest that of king, or local ruler. Parts of the Todtenbuch or Sacred Book of the Dead certainly date from this period, and the great Temple of the Sun at Heliopolis had been founded, for we are told that certain prehistoric Heliopolitan hymns formed the basis of the sacred books of a later age. At Edfu the later temple occupies the site of a very ancient structure, traditionally said to date back to the mythic reign of the gods, and to have been built according to a plan designed by Nuhotef the son of Pthah. At Denderah an inscription found by Mariette in one of the crypts of the great temple, expressly identifies the earliest sanctuary built upon the spot with the time of the Horsheshu. It reads, "There was found the great fundamental ordinance of Denderah, written upon goatskin in ancient writing of the time of the Horsheshu. It was found in the inside of a brick wall during the reign of King Pepi" (_i.e._ Pepi-Merira of the sixth dynasty). The name of Chufu, the king of the fourth dynasty, who built the great pyramid, was found by Naville in a restoration of part of the famous temple of Bubastis, and its foundation doubtless dates back to the same prehistoric period.
