§ 2. General Principles of Form.
The external forms of Egyptian edifices are pyramidoid; in other words, the outward surfaces of their walls affect the form of a trapezium. Thus if we prolong these surfaces vertically we find that they unite at last in a point, in the case of square buildings ([Fig. 58]), and in a ridge in those which are oblong in plan ([Fig. 59]).[92] A square building will sometimes end in a ridge, or aréte, when the principal façade and the corresponding one in its rear are vertical, the other two being inclined.
Horizontal lines predominate over inclined or vertical lines, and buildings, therefore, tend to develop in length and depth rather than in height. To this general rule, however, the pylons afford exceptions.

The terminations of their edifices were also horizontal. There was no necessity for sloping roofs, as, away from the immediate proximity of the sea, it hardly ever rains in Egypt. Moreover, the natural conformation of the country had its influence upon the creations of its inhabitants. The unforeseen and sudden variations, the contrasts of hill and plain, which we find in a mountainous country like Greece, are here unknown. Lower Egypt is a verdant plain, intersected by canals, and stretching from the sea to the desert; in Upper and Middle Egypt the lazy river is accompanied throughout its journey from south to north by two long chains of hills, the Arab chain and the Libyan, whose summits form an almost unbroken line. Between these aspects of nature and the works of man which they enframe, there is a striking general sympathy.[93]

The peculiar character of Egyptian architecture is owing to its lateral extension, and to those wide-spreading bases and foundations which suggest the inclination of the superincumbent walls. In looking at one of these buildings, we feel that it is capable of infinite extension horizontally, and that but one of its dimensions, that of height, is limited by its essential forms. These characteristics give a look of sturdy power to Egyptian architecture which is peculiar to itself, and suggests an idea of unbounded durability.[94]
