We have elsewhere attempted to elucidate the text, which is too abstruse to be discussed here.[139] It translates history into mythology and purports to reveal thereby the transcendent significance of Menes’ achievement. Later generations acknowledged the validity of these early teachings by their deeds: each new king came to Memphis to celebrate the “Union of the Two Lands” and to perform the “Circuit of the White Wall,” as Menes was thought to have done when he had constructed his royal castle.[140] The state which Menes created was habitually referred to as “The Two Lands,” a designation apt to be misunderstood; we meet here—as so often in Egypt—a term with cosmological rather than political connotations. We have shown elsewhere[141] that the dualistic mould of the “Kingdom of Upper and Lower Egypt” satisfied the Egyptian mode of thought which conceived totality as an equilibrium of opposites. A meaningful symmetry was imposed upon the unified land, but it had no basis in fact, for Scorpion and Narmer conquered the north piecemeal, as far as we know. Nor is there any sign of resentment against the north. On the contrary, northerners were found among the highest in the land: two queens of the First Dynasty reveal a Delta origin by their names, and officials of that dynasty, buried near their royal masters at Abydos, exemplify the Lower Egyptian physical type.[142] The outside world did not challenge the exalted view of their state which the Egyptians entertained. None of their neighbours threatened the safety of “The Two Lands”; all of them disposed of natural resources which seemed predestined to be offered as tribute to the divine ruler of Egypt. We have seen that the southern littoral of the Mediterranean was not a desert in antiquity. Narmer’s successors had to consolidate their northern frontiers even though they prevailed with ease over the neighbouring populations. Some had to fight the Libyans in the west. At the malachite mines in Sinai, Semerkhet recorded his victory over the local Bedouin on a rock-stela repeating the main motif of Narmer’s palette. Another king of the First Dynasty had an ivory gaming piece engraved with the picture of a bound Syrian captive. The roofing beams of the royal tombs at Abydos consist of coniferous wood imported from the Lebanon. Jugs of Syrian and Palestinian manufacture have been found in these tombs and in those of dignitaries buried at Saqqara: they probably served as containers of olive oil. Gold, ivory, ostrich feathers, and ebony came through Nubia from inner Africa.
