ree sides of the central apse there
are remains of patterned brickwork. On the buttresses to the southern
wall are roundels with radiating voussoirs in stone and brick, and if
one may judge from the fact that the string-course does not fit the face
of the wall, parts of the exterior of the church were incrusted with
marble. The round-headed windows of the dome cut into its cornice. Under
the church is a cistern[355] which Bondelmontius deemed worthy of
mention.[356] Until some twenty years ago extensive substructures were
visible on the north-east of the church, affording homes for poor Greek
families.[357] They were probably the foundations of the lofty monastery
buildings whose windows commanded the magnificent view of the Golden
Horn that doubtless suggested the epithet Pantepoptes, under which the
Saviour was worshipped in this sanctuary.

S. Saviour Pantepoptes is the most carefully built of the later churches
of Constantinople. The little irregularities of setting out so common in
the other churches of the city are here almost entirely absent. This
accuracy of building, the carving of the string-courses, and the remains
of marble decoration both within and on the exterior, prove exceptional
care.

CHAPTER XV

THE CHURCH OF S. SAVIOUR PANTOKRATOR,
ZEIREK KILISSI JAMISSI

According to the tradition current in the city when Gyllius[358] and
Gerlach[359] explored the antiquities of Constantinople, the large
Byzantine church, now the mosque Zeirek Kilissi Jamissi, overloo
