ARCHITECTURE. 269 Fig. 167 gives a perspective view of the slab that served to close the cell, of which a good view is given in plan. Transverse section (Fig. 168) shows the door open. In Fig. 169 we have two sections of the passage, built of well-prepared units ; the sections are pieced on, but not united one with the other ; the remaining portion of the gallery is of small stones, and the whole surrounded by the earth- work. The next tomb (Figs. 170-173) is a variant of the preceding one. The piers have an inward salience, whose incline is about 20 c. per metre. Dimensions of chamber : length, 2 m. 83 c. ; width on the ground plane, I m. 94 c. ; width flush with the ceiling, i m. 52 c. ; height, 2 m. Width of passage : i m. 29 c. ; height, i m. 72 c. The last monument (Figs. 174, 175) is a simple chamber with- FIG. 167. Sealing slab. Choisy, Fig. 4- FIG. 1 68. Transverse sec- tion. Ibid., Fig. 3. FIG. 169. Longitudinal section.

In Fig. 176 are figured the two sides of the unfinished casing, much enlarged ; they are supposed to be raised from the ground and seen from below. Fig. 177 indicates the place usually occu- pied by the chamber, and the gallery by which it is approached. The earth- work has been obtained by conical layers regu- larly arranged around the Fir..i 7 o.-Lydiantomb. Plan. Ibid., Fig. 5. axis of the mound. The lower zones have a steep incline, which grows less with each successive band. " Indications such as these permit us to understand how the work was carried on. Two gangs were employed at it ; one composed of journeymen to raise the earthwork, and the other of masons to build the vault. For the greater convenience of the
