Rh (which corresponds to that above the "Portone" of the south front) stood, before the earthquake, a wooden sort of verandah, framed, as shown in Fig. 142, and covered by a prolongation of the slope of tiling of the roof. The whole of this had been thrown down, and was lying on the ground at and about the point $$s$$ (in Figs. 139, 142, and Photog. No. 138) in dislocated fragments, from which, collecting and laying together the timber-work, I was able to reconstruct the design of the fabric.

The shock emerging from the eastward had swept over the vertical posts towards the direction of the dotted lines $$n n n n$$, and the tiling of the roof had rent away from the rest at the line of the eave $$r r$$, twisting and drawing out the cross lintels from their sockets in the walls of the house at the eaves, the whole mass then falling in the direction of $$ms$$. The weight of the timber-work was insignificant, the chief mass was in the heavy tiling which it carried. A line drawn from the position of the centre of gravity of this (the projecting tiled roof) to the centre of gravity of
