The architectural wonders of Egypt and of Greece were as diverse from each other as the natural features of the soil, and in each case the structures were in keeping and in harmony with the character of the landscape which they respectively adorned. The harmony was, however, that of contrast, and not of correspondence. In Greece, where the landscape itself was grand and sublime, the architect aimed only at beauty. To have aimed at magnitude and grandeur in human structures among the mountains, the cliffs, the cataracts, and the resounding ocean shores of Greece, would have been absurd. The Grecian artists were deterred by their unerring instincts from the attempt. They accordingly built beautiful temples, whose white and symmetrical colonnades adorned the declivities, or crowned the summits of the hills. They sculptured statues, to be placed on pedestals in groves and gardens; they constructed fountains; they raised bridges and aqueducts on long ranges of arches and piers; and the summits of ragged rocks crystallized, as it were, under their hands into towers, battlements, and walls. In Egypt, on the other hand, where the country itself was a level and unvarying plain, the architecture took forms of prodigious magnitude, of lofty elevation, and of vast extent. There were ranges of enormous columns, colossal statues, towering obelisks, and pyramids rising like mountains from the verdure of the plain. Thus, while nature gave to the country its elements of beauty, man completed the landscape by adding to it the grand and the sublime.
The shape and proportions of Egypt would be represented by a green ribbon an inch wide and a yard long, lying upon the ground in a serpentine form; and to complete the model, we might imagine a silver filament passing along the center of the green to denote the Nile. The real valley of verdure, however, is not of uniform breadth, like the ribbon so representing it, but widens as it approaches the sea, as if there had been originally a gulf or estuary there, which the sediment from the river had filled.
In fact, the rich and fertile plain which the alluvial deposits of the Nile have formed, has been protruded for some distance into the sea, and the stream divides itself into three great branches about a hundred miles from its mouth, two outermost of which, with the sea-coast in front, inclose a vast triangle, which was called the Delta, from the Greek letter _delta_, (Greek: D), which is of a triangular form. In ascending the river beyond the Delta, the fertile plain, at first twenty-five or thirty miles wide, grows gradually narrower, as the ranges of barren hills and tracts of sandy deserts on either hand draw nearer and nearer to the river. Thus the country consists of two long lines of rich and fertile intervals, one on each side of the stream. In the time of Xerxes the whole extent was densely populated, every little elevation of the land being covered with a village or a town. The inhabitants tilled the land, raising upon it vast stores of corn, much of which was floated down the river to its mouth, and taken thence to various countries of Europe and Asia, in merchant ships, over the Mediterranean Sea. Caravans, too, sometimes came across the neighboring deserts to obtain supplies of Egyptian corn. This was done by the sons of Jacob when the crops failed them in the land of Canaan, as related in the sacred Scriptures.
