Indeed, the native name of Heliopolis is suggestive of Asiatic relations. It is the On of the Old Testament, and was called On of the north to distinguish it from another On, the modern Erment, in the south. It was symbolised by a fluted and painted column of wood,(58) in which some have seen an emblem of the sun-god, like the sun-pillars of Semitic faith. But the name of On was not confined to Egypt. There was another Heliopolis in Syria, called On of the Beka’a by Amos (i. 5), where the sun-god was worshipped under the form of a stone. And in Palestine itself Beth-el, “the house of God,” was known in earlier ages as Beth-On. It is true that the name of On may have been carried into Asia in the days when the Hyksos dynasties ruled over Egypt, but it is more probable that both Beth-On and the On near Damascus go back to an older date. In any case they testify to some kind of contact between the sun-worship of Heliopolis in Egypt and that of Syria and Palestine.(59) Between Tum, the sun-god of Northern Egypt, and Horus, the sun-god of the South, there was one notable difference. While Horus was a hawk, Tum was a man. In this respect, again, he resembled the gods of Babylonia, who are always depicted in human form. It is difficult to find any other Egyptian deity who was similarly fortunate. Osiris, indeed, was originally a man, but at an early date he became confounded with his symbol, the ram, in his title of “lord of Daddu.” Professor Maspero thinks that Khnum at the Cataract may also have been originally a man; but if so, he too became a ram before the beginning of history. Ptaḥ of Memphis and Anher of This are the only other gods who appear consistently in human shape, and Ptaḥ is a mummy, while Anher, like Tum, was the sun.(60) With the adoption of the Ennead and the cosmological ideas it embodied, a new element entered into the theology of the Egyptian temples. This was the identification of one god with another, or, to speak more exactly, the loss of their individuality on the part of the gods. The process was begun when the priests of Heliopolis took such of the divinities as were recognised throughout Egypt, and transmuted them into successive phases in the creative action of their local god. It was completed when other religious centres followed the example of Heliopolis, and formed Enneads of their own. In each case the local god stood of necessity at the head of the Ennead, and in each case also he was assimilated to Tum. Whatever may have previously been his attributes, he thus became a form of the sun-god. A dual personality was created, which soon melted into one.
