+EARLY BEGINNINGS.+ It is impossible to trace the early stages of the process by which true architecture grew out of the first rude attempts of man at building. The oldest existing monuments of architecture--those of Chaldæa and Egypt--belong to an advanced civilization. The rude and elementary structures built by savage and barbarous peoples, like the Hottentots or the tribes of Central Africa, are not in themselves works of architecture, nor is any instance known of the evolution of a civilized art from such beginnings. So far as the monuments testify, no savage people ever raised itself to civilization, and no primitive method of building was ever developed into genuine architecture, except by contact with some existing civilization of which it appropriated the spirit, the processes, and the forms. How the earliest architecture came into existence is as yet an unsolved problem. +PRIMITIVE ARCHITECTURE+ is therefore a subject for the archæologist rather than the historian of art, and needs here only the briefest mention. If we may judge of the condition of the primitive races of antiquity by that of the savage and barbarous peoples of our own time, they required only the simplest kinds of buildings, though the purposes which they served were the same as those of later times in civilized communities. A hut or house for shelter, a shrine of some sort for worship, a stockade for defence, a cairn or mound over the grave of the chief or hero, were provided out of the simplest materials, and these often of a perishable nature. Poles supplied the framework; wattles, skins, or mud the walls; thatching or stamped earth the roof. Only the simplest tools were needed for such elementary construction. There was ingenuity and patient labor in work of this kind; but there was no planning, no fitting together into a complex organism of varied materials shaped with art and handled with science. Above all, there was no progression toward higher ideals of fitness and beauty. Rudimentary art displayed itself mainly in objects of worship, or in carvings on canoes and weapons, executed as talismans to ward off misfortune or to charm the unseen powers; but even this art was sterile and never grew of itself into civilized and progressive art.
