It is not true, as you might suppose, that these latter were later in development than the art of architecture. Far from it. In rude pre-historic ages, when the knowledge of building had not advanced beyond the question of mere safety, we find delicate and beautiful ornaments put upon arms and on personal decorations. The most elaborate tattooing of the savage is consistent with extreme rudeness in his dwelling.[20]
The earliest form of house we know, which was designed not only for shelter and durability, but also for safety, is the _underground_ beehive house. Beehive huts of stone are common in many nations, and may perhaps best be seen now in the huts of the monks on the wild rock of Skellig Michael, which is the nearest land in the British Islands to the traveller coming from America. But such huts are not easily defended against an enemy. This latter advantage is obtained by making the hut a chamber underground,[21] and only to be entered by a passage long, narrow, and low, in fact a sort of horizontal shaft into which the enemy can only creep on hands and feet, and so can have his head chopped off as soon as it appears within the chamber, without possibility of using his weapons. I have seen this form of house in the most primitive village of the stone and bone age, which is known as the Weem of Scale, on a very wild bay of the main island of the Orkneys, looking northwest into the Atlantic. There, under the sands accumulated by the gales of thousands of years, we find small subterranean huts, with nooks in the stone work to hold rude vessels and implements, and with a low covered way for the owner to creep in and find himself at home. The weapons found in such houses, many of which are yet unexplored, are either of stone or bone or shell. These dwellings, once a very general type--for remember, similar wants in mankind produce similar satisfactions of that want in the most widely severed parts of the world--usually come to us in the stage of survival, when men had already learned other kinds of architecture. Hence they often preserved for the dwellings of the dead this type of underground beehive house with a long and narrow approach, though as time went on the house was made higher, and the avenue of approach better (as we have it in the famous New Grange in Ireland), and they even ornamented the inner surface of the slabs that formed the walls. As usual, the prehistoric Greeks did it all more perfectly than the rest of the world. The beehive house known in former days as the Treasury of Atreus, but now recognised as a tomb of some prehistoric king, is a splendid building fifty feet high, and made of thirty-three horizontal courses of stone overlapping as they rise, with the inner surfaces cut to form a conical chamber. Not only are large lintel stones used, but there were rosettes of bronze ornamenting the inner surface of the walls, and the stately avenue (_dromos_) lined with stone work of great finish and open to the sky, led to an ornamented gate or entrance. A restoration of this entrance, made by the aid of the actual pillars carried home long ago by the Marquis of Sligo, now astonishes the student of prehistoric art in the British Museum.[22] Why do I, however, delay over this very perfect and beautiful kind of building of which another noted specimen is the Tomb of the Minyæ at Orchomenos in Bœotia?[23] In the first place, to show you how the highly developed and finished forms were the gradual perfection of the oldest and rudest protected house, to which they merely added height, careful finish, and ornament, which ornament we know from Egyptian parallels to date some fifteen centuries before Christ; secondly, to bring home to you the important fact that the beehive or round house was at an early date abandoned to the use of the dead, and not employed for the use of the living till quite late in Greek history, when a few round public buildings show that the idea had not been lost. The men that built the great and elaborate tomb of Atreus probably never themselves lived in a round or beehive, but in a square house. They only maintained the round form out of respect for the dead, and indeed for the sake of the safety of the treasures buried with the dead.
