But Egypt was not only responsible for inaugurating the use of stone for building. For another forty centuries she continued to be the inventor of new devices in architecture. From time to time methods of building which developed in Egypt were adopted by her neighbours and spread far and wide. The shaft-tombs and mastabas of the Egyptian Pyramid Age were adopted in various localities in the region of the Eastern Mediterranean,[20] with certain modifications in each place, and in turn became the models which were roughly copied in later ages by the wandering dolmen-builders. The round tombs of Crete and Mycenæ were clearly only local modifications of their square prototypes, the Egyptian Pyramids of the Middle Kingdom. "While this Ægean art gathered from, and perhaps gave to, Egypt, it passed on its ideals to the north and west of Europe, where the productions of the Bronze Age clearly show its influence" (Lethaby, p. 78) in the chambered mounds of the Iberian peninsula and Brittany, of New Grange in Ireland and of Maes Howe in the Orkneys.[21] In the East the influence of these Ægean modifications may possibly be seen in the Indian stupas and the dagabas of Ceylon, just as the stone stepped pyramids there reveal the effects of contact with the civilizations of Babylonia and Egypt.

Professor Lethaby sees the influence of Egypt in the orientation of Christian churches (p. 133), as well as in many of their structural details (p. 142); in the domed roofs, the iconography, the symbolism, and the decoration of Byzantine architecture (p. 138); and in Mohammedan buildings wherever they are found.

For it was not only the architecture of Greece, Rome, and Christendom that received its inspiration from Egypt, but that of Islâm also. These buildings were not, like the religion itself, in the main Arabic in origin. "Primitive Arabian art itself is quite negligible. When the new strength of the followers of the Prophet was consolidated with great rapidity into a rich and powerful empire, it took over the arts and artists of the conquered lands, extending from North Africa to Persia" (p. 158); and it is known how this influence spread as far west as Spain and as far east as Indonesia. "The Pharos at Alexandria, the great lighthouse built about 280 b.c., almost appears to have been the parent of all high and isolated towers.... Even on the coast of Britain, at Dover, we had a Pharos which was in some degree an imitation of the Alexandrian one." The Pharos at Boulogne, the round towers of Ravenna, and the imitations of it elsewhere in Europe, even as far as Ireland, are other examples of its influence. But in addition the Alexandrian Pharos had "as great an effect as the prototype of Eastern minarets as it had for Western towers" (p. 115).

I have quoted so extensively from Professor Lethaby's brilliant little book to give this independent testimony of the vastness of the influence exerted by Egypt during a span of nearly forty centuries in creating and developing the "matrix of civilization". Most of this wider dispersal abroad was effected by alien peoples, who transformed their gifts from Egypt before they handed on the composite product to some more distant peoples. But the fact remains that the great centre of original inspiration in architecture was Egypt.

The original incentive to the invention of this essentially Egyptian art was the desire to protect and secure the welfare of the dead. The importance attached to this aim was intimately associated with the development of the practice of mummification.

With this tangible and persistent evidence of the general scheme of spread of the arts of building I can now turn to the consideration of some of the other, more vital, manifestations of human thought and aspirations, which also, like the "matrix of civilization" itself, grew up in intimate association with the practice of embalming the dead.

I have already mentioned Professor Lethaby's reference to architecture and agriculture as the two arts that have changed the surface of the world. It is interesting to note that the influence of these two ingredients of civilization was diffused abroad throughout the world in intimate association the one with the other. In most parts of the world the use of stone for building and Egyptian methods of architecture made their first appearance along with the peculiarly distinctive form of agriculture and irrigation so intimately associated with early Babylonia and Egypt.[22]

But agriculture also exerted a most profound influence in shaping the early Egyptian body of beliefs.

I shall now call attention to certain features of the earliest mummies, and then discuss how the ideas suggested by the practice of the art of embalming the dead were affected by the early theories of agriculture and the mutual influence they exerted one upon the other.
