If the characteristic Egyptian conception of kingship first received pictorial expression under Narmer, it found its first literary embodiment in a famous text which, from internal evidence, must likewise be assigned to the formative years of Egypt.[137] This is the so-called Memphite Theology. The lasting value of the theory of kingship which it expounded is shown by the fact that the only copy now extant was made as late as the reign of king Shabaka in the eighth century B.C. Moreover, it relates the theory with an act of Menes, the founding of Memphis. The text concerns us, therefore, because of the date of its inception; the act which it presupposes; and the interpretation which it offers. The significance of the age of our text is evident. In view of the overriding importance of the institution of kingship for Egyptian society, the formulation of a theory of kingship at the very beginning of the monarchy aptly illustrates the emergence of the “form” of Egyptian civilization at that critical time. Reference to the founding of Memphis is made in our text by implication: its tenor is to emphasize the profound significance of the city. Thus the content corroborates the linguistic evidence for an early date of the document, since a trustworthy tradition, preserved by Herodotus, ascribed the founding of Memphis to Menes. The text expounds the theology of the new foundation. Of the actual course of events the following account survived into Greek times: it was believed that Menes threw up a dike across the western part of the valley north of the Fayum, thus compelling a branch of the Nile to rejoin the main stream, and reclaiming fifty miles of valley. On the newly won land he then founded a royal castle, a little to the south of modern Cairo. It was called “The White Walls,” and thus characterized as an Upper Egyptian foundation—for white was the colour of the mother-goddess Nekhbet, the protectress of Upper Egypt and of the king’s house. But the new settlement was not really a capital of the united country. The successors of Menes in the First and Second dynasties did not even reside there. They seem to have maintained their residence at This and were buried in neighbouring Abydos,[138] within the district whence their ancestors had come. Memphis was originally—and remained for fifteen hundred years almost exclusively (see pp. 97 f.)—a sacred city, the locus where events of unparalleled importance for the Egyptian commonwealth had taken place. The Memphite Theology deals precisely with these events.
