At cc the collapse of the upper portion has extended to the substruc-

with two ribs intersecting in the centre. The ribs, like those in the vaulting
of the so-called ‘ temple of Minerva Medica ’ near the Porta Maggiore-
really a large nymphaeum (see Giovannoni La sala termale degli orti liciri-
iani, in Annali della societa degli Ingegneri ed Architetti italiani, 1904) do
not consist entirely of tiles, but only in part, the interstices being filled with
lighter material, while the rest of the vault was built of similar material
after the ribs had been constructed. The ribs are 0'65 metre wide ;
the interval between the large bonding tiles in the ribs is 0'40 metre.
This is perhaps the earliest datable appearance of such ribs in Roman
architecture.
The substructions under the centre and S.W. part of the great hall hh
have quadripartite vaulting, and the rest (as those of gg and ii) barrel
vaulting, in which ribs of the character above described may be seen. Near
the W. angle there is a complete mixture, allowing of no distinction of
dating, of opus reticulatum of tufa with tufa quoins, and facing with small
rectangles of peperino, bands of brickwork alternating with both these forms
