It is through its temples and tombs that ancient Egypt is mainly known to us. It is true that the warm and rainless climate of Upper Egypt has preserved many of the objects of daily life accidentally buried in the ruins of its cities, and that even fragments of fragile papyrus have come from the mounds that mark the sites of its villages and towns; but these do not constitute even a tithe of the monuments upon which our present knowledge of ancient Egyptian life and history has been built. It is from the tombs and temples that we have learned almost all we now know about the Egypt of the past. The tombs were filled with offerings to the dead and illustrations of the daily life of the living, while their walls were adorned with representations of the scenes at which their possessor had been present, with the history of his life, or with invocations to the gods. The temples were storehouses of religious lore, which was sculptured or painted on their walls and ceilings. In fact, we owe most of our knowledge of ancient Egypt to the gods and to the dead; and it is natural, therefore, that the larger part of it should be concerned with religion and the life to come.
We are thus in an exceptionally good position for ascertaining, at all events in outline, the religious ideas of the old Egyptians, and even for tracing their history through long periods of time. The civilisation of Egypt goes back to a remote past, and recent discoveries have carried us almost to its beginnings. The veil which so long covered the origin of Egyptian culture is at last being drawn aside, and some of the most puzzling inconsistencies in the religion, which formed so integral a part of that culture, are being explained. We have learnt that the religion of the Egypt which is best known to us was highly composite, the product of different races and different streams of culture and thought; and the task of uniting them all into a homogeneous whole was never fully completed. To the last, Egyptian religion remained a combination of ill-assorted survivals rather than a system, a confederation of separate cults rather than a definite theology. Like the State, whatever unity it possessed was given to it by the Pharaoh, who was not only a son and representative of the sun-god, but the visible manifestation of the sun-god himself. Its unity was thus a purely personal one: without the Pharaoh the Egyptian State and Egyptian religion would alike have been dissolved into their original atoms.
