of the ancient world, about a thousand years before our present era, and when the Greeks first, or soon after, began to erect temples, there existed no science complete in itself, or whose principles even had been elicited from the chaotic mass of materials, by which they could have been directed, in their own matchless monuments. Whatever of grace and of beauty--of dignity and truth--of sublimity and harmonious proportion,--whatever of architectonic excellence, grounded on the most profound principles of taste, and established on the sure basis of geometry,--whatever of all this can be discovered in the building of Greece, she owes it to the superiority of native genius. Yet the obligations to Egyptian predecessors were neither few nor unimportant. The rectangular area, in which the breadth should bear a proportion less to the length, a shape of all others best adapted to beauty and convenience, was introduced. A still less obvious source of almost every higher beauty in the science--columnar architecture--was there practised so early, that whether it originated in the country, or was introduced, is unknown. Even the system of ornament may, in its rise at least, be traced in these primeval remains; for not a single detail afterwards introduced may not, in a rudimental, often nearly perfected state, be remarked; especially the beautiful idea of floral ornaments. Lastly, in the works of Egyptian art, very perfect examples of mechanical practice, both in dressing and laying the materials, might be observed in almost every instance. All these elements, however, the last excepted, jarring among themselves, whether as wholes or parts, were to be selected, arranged, methodized, and animated by grace, harmony, nobleness,--in short, the science of architecture was yet to be created.
