ing an aisle and gallery. This is the normal domed
basilica construction. Here, if we regard the floor of the upper passage
(B on plan, p. 318) as the remains of the old gallery floor,--and no
other view seems to account for its existence,--the internal elevation
was in three stories, an aisle at the ground level, above it a gallery,
and above that, in the arch tympanum, a triple window. Such an
arrangement is, so far as we know, unique in a small church, but it is
the arrangement used in S. Sophia, Constantinople, and may well have
been derived from that church. The opening is only about one-half of
the space, leaving a broad pier at each side. In this it differs from S.
Sophia, Salonica, but such side piers are present in S. Sophia,
Constantinople. The diagrams show a restoration of the plan and internal
bay based on these conclusions (Figs. 102, 103).

The gallery on the north side is an addition. The character of the
brickwork and of the windows is later than the central church, but the
lack of windows on the ground floor suggests that the 'aisle' was
originally lighted from the body of the church. The vaulting gives no
clue, nor are there traces of an opening in the wall between the 'aisle'
and the church. The floor level is much higher than that of the passage
'B' (p. 318) on the opposite side, and seems to be a new level
introduced when the addition was made and the wall thickened.

If these conclusions are correct the church was originally a domed
basilica resembling S. Sophia, Salonica, in plan and S. Sophia,
Constantinople, in elevation. The side dome arches had double arcades in
two stories, and above them windows in the dome arches. There are at
present no traces of a western gallery, but such may have existed below
the present west windows. Later in the history of the church came
alterations, which included the ribbed domes and the gallery on the
north side. The side aisles still communicated with the church and the
lateral chapels with the bema.
