The interior curve of the _upper wall_ of the apse had a radius of about 22 ft., and the width of a central “nave” agreeing with this can hardly have been less than 50 ft.; the total internal width, supposing there were “aisles” in line with the “chambers” at the end, would have been about 110 ft. There were thick transverse walls across the front of the apse, and again about 20 ft. to the west. I give (Fig. 22) a plan adapted from _Archæologia_; the walls shown black were not necessarily all above the floor level, although they are thinner than the lowest foundations. (Note that in the plan in _Archæologia_ the scale is given in divisions of 12 ft., and not of 10 ft. as usual.) [Illustration: FIG. 22. ] My plan is restored as a possible reading of the evidence; the most certain parts are those in black (A); the foundations (B) may be of a different age; at the left (C) is the brick pier or wall against Gracechurch Street. A structure perhaps 110 ft. wide with a central avenue of 50 ft. would have been exceptional; on the other hand, a Basilica 220 ft. to 250 ft. long including the apse would have been rather short. One of the walls found to the west of Gracechurch Street was bent in its line as if it might have been against a stream. The nature of the site might have dictated a rather short and very wide building. It should be noticed that the line of Gracechurch Street is nearly or exactly at right angles to the great building. Hodge’s drawings show that the walls of Leadenhall Market were built directly on the Roman foundations, and hence square with them. The Basilica would have had ranges of Corinthian columns and perhaps a transverse row on the foundation in front of the apse, as at the Basilica Ulpia in Rome and at Pompeii: compare also the transverse walls at the Basilicas of Cirencester and Caerwent. The roof would probably have had trusses of low pitch exposed to the interior, like those of the early Christian churches. In 1908 a Roman wall, 3½ ft. wide, _parallel_ to Gracechurch Street, was found at No. 85. In 1912 a fine Roman wall, 4½ ft. wide, running north and south, was found just south of Corbet’s Court; turning at right angles it passed under Gracechurch Street. It was of ragstone with double courses of tiles; the base was 27 ft. below the present level; a piece of thinner wall ran close and _parallel_ with the roadway (_Archæologia_, lxiii.). Kelsey noted that in 1834 massive walls were found in Gracechurch Street from Corbet’s Court to the head of the street (_Archæologia_, lx.).
