The plan of the church presents the simplest form of the domed-cross type without galleries. The dome, without drum, ribs, or windows, is almost certainly a Turkish reconstruction, but the dome arches and piers are original. The arms of the cross and the small chambers at its angles are covered with barrel vaults, and communicate with one another through lofty, narrow arches. In the treatment of the northern and southern walls of the building considerable architectural elaboration was displayed. At the floor level is a triple arcade; higher up are three windows resting on the string-course; and still higher a window divided into three lights. The arches in the church are enormously stilted, a feature due to the fact that the only string-course in the building, though structurally corresponding to the vaulting spring, has been placed at the height of what would properly be the column string-course. The three apses, much altered by repairs, project boldly, all of them showing three sides on the exterior. The roof and the cornice are Turkish, and the modern wooden narthex has probably replaced a Byzantine narthex. On the opposite side of the street lies a cruciform font that belonged to the baptistery of the church. [Illustration: FIG. 63.] From a church of this type to the later four-columned plan is but a step. The dome piers of SS. Peter and Mark are still [Symbol: L]-shaped, and form the internal angles of the cross. As the arches between such piers and the external walls increased in size, the piers became smaller, until eventually they were reduced to the typical four columns of the late churches.
