During the pre-historic period of man’s artistic development we find a peculiar similarity between his dwellings and his tombs. The mountain cavern, and the hut constructed of beams and boughs, covered with skins, were undoubtedly men’s first stately palaces. The very oldest traditions bear out this statement. The earliest inhabitants of Greece dwelt in mountain caverns. The people of Siberia, anterior to the Samoyedes, lived, according to Erman, in subterranean caves. The Kyklops of Homer are but nomads, residing in mountain caverns. Of the Hittites, a tribe in Canaan in the times of Abraham, it is recorded that they buried their dead in caves. But it is an incontestable fact that the burial-places resembled the dwellings of the pre-historic man. Crypts, catacombs, and rock-hewn temples may be set down as having originated from man’s first mountain home. The tombs of the Tartars in Kasan resemble their houses on a small scale. A Circassian tomb resembles a Circassian cottage. The tombs of the Karaite Jews in the valley of Jehoshaphat, are like their houses. Laplanders live in caves. The aborigines of Germany and France, the contemporaries of the mammoth, rhinoceros, auerochs and elk, dwelt in caves, as their bones are found mingled with those of these now extinct animals, together with various implements, such as adzes, flint arrows, stone knives, and even, as in the cave at Perigord on the borders of the Dordogne, works of art of great artistic power. Jordanes, in his ‘De Rebus Geticis,’ mentions people in Sweden (Scania) living like wild animals in caves, cut out in the rocks. But the nomad savage could find such dwellings only where there were mountains. If he wandered out of such a district into the plains, and wanted to shelter himself from the inclemency of the weather, he had to collect blocks of stone, and to form with them artificial caves. In this manner cromlechs, Dös, Dyss or dolmens, and gallery chambers arose, in which the long, narrow gallery corresponds to the confined entrance of the mountain-cave, and the chamber to the cavern.
