Traces of the older structure remain in the wall between the church and the parecclesion. The space already described, which originally opened from the passage at the higher level to the south cross-arm, corresponds in width both to the window above and to the space occupied by the doors below. At S. Sophia, Salonica, the side-arms are filled in with arcades in two stories forming 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). [Illustration: FIG. 102.--S. SAVIOUR IN THE CHORA (restored plan).] 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.

CAPITAL AT THE ENTRANCE TO THE PARECCLESION. _To face page 314._] 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. [Illustration: FIG. 103.--S. SAVIOUR IN THE CHORA (restored bay).]
