Mr. Joyce believes that thi buried wall mu~t have been built before tho reign of Claudius II., who died 270 A.D. vVe see in the accompanying section, Fig. 15, that the te"·selated pavement has subsided to a less degree over the buried wall than elsewhere ; so that a slight convexity or protuberance here stretched in a straight line across the room. This led to a hole being dug, and the buriecl wall was thus discovered. We see in tltese three sections, and in several others not given, that the old pavements have sunk or sagged considerably. Mr. Joyce formerly attributed this sinking solely to the slow settling of the ground. That there has been some settling is l1ighly probable, ancl it may be seen in section 15 that the paven1ent for a width of 5 feet over the southern enlargement of the room, which must have been built on fresh ground, has sunk a little more than on the old northern side. But this sinking Inay possibly have had no connection with the enlargernent of the room, for in Fig. 13, one half of the pave1nent has subsided more |
