Byzantine Churches in Constantinople: Their History and Architecture

by Alexander Van Millingen; Walter S. George; Arthur E. Henderson; Ramsay Traquair

As the history of the church prepares us to expect, the building presents a very irregular plan. The central area is a short-armed Greek cross surmounted by a dome, and terminating to the east in a large apse flanked by side chapels now disconnected from it. To the west are two narthexes, on the south a parecclesion, and on the north a gallery in two stories.

As the central part of the church is the oldest and of the greatest interest, the description will begin with the interior, and deal afterwards with the later exterior accretions.

Only two doors lead from the inner narthex to the church, one of them in the centre of the axis and the other to the north. The absence of the corresponding and customary third door, for which there is space on the south side, should be noticed, as it throws light on the original plan of the building. The doors are beautifully treated with marble mouldings and panelled ingoes; the door to the north recalls the sculptured door in the south gallery of S. Sophia, but, unfortunately, the carved work of the panels has been destroyed. Above the central door, on the interior, is a porphyry cornice carved with peacocks drinking at fountains (Plate [LXXXVII.]). Large portions of the beautiful marble revetment on the walls of the church happily remain intact, and nowhere else in Constantinople, except in S. Sophia, can this splendid method of colour decoration be studied to greater advantage. Slabs of various marbles have been split and placed on the walls so as to form patterns in the veining. The lower part is designed as a dado in Proconessian striped marble, with upright posts of dark red at the angles and at intervals on the longer stretches of wall, and rests on a moulded marble base. Above the dado are two bands, red and green, separated from the dado and from each other by white fillets. The upper part is filled in with large panels, especially fine slabs of brown, green, or purple having been selected to form the centre panels. The plainer slabs of the side panels are framed in red or green borders, and outlined with fillets of white marble either plain or carved with the 'bead and reel.' The arches have radiating voussoirs, and the arch spandrils and the frieze under the cornice are inlaid with scroll and geometrical designs in black, white, and coloured marbles. The cornice is of grey marble with a 'cyma recta' section, and is carved with an upright leaf. [537]

On the eastern walls of the north and south cross arms, and flanking the apse, eikon frames similar to those in the Diaconissa (p. [186]) are inserted. The northern frame encloses a mosaic figure of Christ holding in His hands an open book, on which are the words, 'Come unto Me all ye who labour and are heavy laden.' [538] In the corresponding frame to the south is the figure of the Virgin, and, above it, an arch of overhanging acanthus leaves enclosed within a square frame with half figures of angels in the spandrils. The arch encloses a medallion bust, the head of which is defaced, but which represented the Saviour, as is proved by the indication of a cross on the aureola. The spaces at the sides of the medallion are filled in with a pierced scroll showing a dark slab of porphyry behind it, making a very beautiful arrangement. These frames are distant from the eikonostasis, which stretched across the front of the bema arch, nearer to the apse. On the south side are two doors leading to the parecclesion, and on the north side above the cornice is a small window from the north gallery.

The dome rests on a ribbed drum of sixteen concave segments, and is pierced by eight windows corresponding to the octagonal form of the exterior. The original crown has fallen and been replaced by the present plain Turkish dome. The prothesis and the diaconicon are represented by chapels to north and south of the apse. As already stated, they do not now communicate with the bema, although the position of the old passages between them and the bema is marked by niches in the marble revetment. From the fact that the Byzantine marble work is continued across these passages it is evident that the chapels were cut off from the apse in Byzantine days. The north chapel is covered by a drum dome of eight concave sections, and is entered from the lower story of the gallery on the north side of the church. It should be noticed that the chapel is not placed axially to this gallery. The south chapel is covered by a plain drum dome, and is now entered from the parecclesion, evidently as the result of the alterations made when the parecclesion was added.

The exterior is very simply treated. The side apses show three sides of an octagon. The central apse has five sides of a very flat polygon, and is decorated with hollow niches on each side of a large triple window. It was at one time supported by a large double flying buttress, but the lower arch has fallen in. As the buttress does not bond with the wall it was evidently a later addition.

The inner narthex is entered from the outer narthex by a door to the west. It is with its resplendent marble revetment and brilliant mosaics a singularly perfect and beautiful piece of work, one of the finest gems of Byzantine Art. It is divided into four bays, and is not symmetrically placed to the church. The door stands opposite to the large door of the church and is in the central axis of the building. The bay which it occupies and that immediately to the north are covered by dome vaults resting on strong transverse arches and shallow segmental wall arches. [539] The northern end bay is covered with a drum dome of sixteen hollow segments pierced by eight windows. The bay to the south of the door is considerably larger than the other bays, and is covered by a dome similar in character to that over the northern end bay but of greater diameter. At the south end of the narthex a small door leads to the return bay of the outer narthex in front of the parecclesion.
