The physical division of Egypt was itself a magical synthesis, and the names of its provinces corresponded to the ciphers of sacred numbers. The realm of Sesostris was divided into three parts; of these Upper Egypt, or the Thebaid, was a type of the celestial world and the land of ecstasy; Lower Egypt was the symbol of earth; while Middle or Central Egypt was the land of science and of high initiation. Each of these parts was subdivided into ten provinces, called Nomes, and was placed under the particular protection of a god. There were therefore 30 gods and they were grouped by threes, giving symbolical expression in this manner to all possible conceptions of the triad within the decad, or otherwise to the threefold material, philosophical and religious significance of absolute ideas attached primitively to numbers. We have thus the triple unity or the first triad, the triple binary[48] formed by the first triad and its reflection, being the Star of Solomon; the triple triad or the complete idea under each of its three forms; the triple quaternary, being the cyclic number of astral revolutions, and so onward. The geography of Egypt under Sesostris is therefore a pantacle or symbolical summary of the entire magical dogma originating with Zoroaster and rediscovered or formulated more precisely by Hermes. In this manner did the land of Egypt become as a great volume and the instructions contained therein were multiplied by translation into pictures, sculptures, architecture through the length and breadth of the towns and in all temples. The very desert had its eternal teachings, and its word of stone was set squarely on the foundations of the pyramids. The pyramids themselves stood like boundaries of the human intelligence, in the presence of which the colossal sphinx meditated age after age, sinking by insensible degrees into the desert sand. Even at this day its head, defaced by the work of time, still emerges from its sepulchre, as if waiting expectantly the signal for its complete entombment at the coming of a human voice revealing to a new world the problem of the pyramids.
