It must, of course, be remembered that the foregoing generalisations apply to the Egyptian people as a whole. There were individual exceptions; there was even a class the lives of whose members were not devoted to agricultural or other labour, and whose religious conceptions were often spiritual and sublime. This was the class of priests, whose power and influence increased with the lapse of time, and who eventually moulded the official theology of Egypt. Priestly colleges arose in the great sanctuaries of the country, and gradually absorbed a considerable part of its land and revenues. At first the priests do not seem to have been a numerous body, and up to the last the higher members of the hierarchy were comparatively few. But in their hands the religious beliefs of the people underwent modification, and even a rudimentary systematisation; the different independent cults of the kingdom were organised and combined together, and with this organisation came philosophic speculation and theorising. If Professor Maspero is right, the two chief schools of religious thought and systematising in early Egypt were at Heliopolis, near the apex of the Delta, and Hermopolis, the modern Eshmunên, in Central Egypt. In Hermopolis the conception of creation, not by voice merely, but even by the mere sound of the voice, was first formed and worked out while Heliopolis was the source of that arrangement of the deities into groups of nine which led to the identification of the gods one with another, and so prepared the way for monotheism.(7) If Heliopolis were indeed, as seems probable, the first home of this religious theory, its influence upon the rest of Egypt was profound. Already in the early part of the historical period, in the age of the Fifth and Sixth Dynasties, when the religious texts of the Pyramids were compiled, the scheme which placed the Ennead or group of nine at the head of the Pantheon had been accepted throughout the country. It was the beginning of an inevitable process of thought, which ended by resolving the deities of the official cult into forms or manifestations one of the other, and by landing its adherents in pantheism.
