The countries in which it has been managed with the greatest power and originality are those whose soil lent itself most kindly to the work of excavation. The limestone and sandstone chains of the Nile valley, the abrupt flanks of Persian ravines, of Cappadocian and Lycian hillsides, and the rocky slopes of Greece and Etruria, were excellently fitted for the work of the funerary architect. If the civilization of the Mesopotamian Semites had originated in the country above Nineveh, at the foot of those hills in which the Tigris has its springs, the fathers of the people would perhaps have cut tomb chambers like those of Egypt in the soft gypsum, and, in later years, their descendants, instead of breaking entirely with the traditions of the past would have raised _tumuli_ in the plains and constructed within them brick chambers to take the place of vaults cut in the living rock. Chaldaea would then have been dotted over with sepulchral mounds like those with which the steppes of central Russia are covered. Nothing of the kind has as yet been discovered; none of the _tells_ or mounds of sun-dried bricks have yet been identified as tombs, and that is because, as we have seen, the course of civilization was from south to north; the first impulse came from the shores of the Persian Gulf, from the people inhabiting alluvial plains consisting merely of sand and broken stone. From the very first hour these people had to compel clay, kneaded and dried in the sun or the brick kiln, to render the services which are demanded from stone elsewhere. They were content therefore with entombing their dead either in small brick vaults, under large terra-cotta covers, or in coffins of the latter material. The tomb chamber illustrated in our Fig. 89 may be taken as a type. It is five feet high by seven feet long, and three feet seven inches wide. The vault is closed at the top by a single row of bricks and at each end by a double wall of the same material. There are no doors. The tombs once shut must have been inaccessible. The structure was put together with such care that neither dust nor water could get within it. Some of these graves, and among them this particular one, inclosed only one skeleton. Taylor found fourteen clay vases in it, not to mention other objects such as a walking stick, rings, cylinders, and bronze cups. Besides these there was a gold waist-band about an inch wide, showing it to be the grave of a rich man. In other tombs as many as three, four, and even eleven skeletons were found. In these the brick under the head and the bronze cup in the hand were sometimes missing, but the water jars were always there. [Illustration: FIG. 163.--Tomb at Mugheir; from Taylor.]
