t unaltered; to the right, the original filling
of the dome arch forms a 'nave-arcade' similar to that of the mosque of
Sultan Bayazid; while by means of the additional apses the building has
been converted into a miniature imperial mosque of the S. Sophia type, a
distinctly clever piece of Turkish alteration.

In its original form the central dome was surrounded by an 'ambulatory'
of one story formed by the aisles and 'inner narthex.' Such a plan is
common to both the domed basilica type and the domed cross type, the
difference depending upon the treatment of the cross arms above. In both
types, however, the side dome arches are invariably filled in with
arcades similar to that filling in the western arch of S. Andrew. We are
therefore justified in restoring such arcades here. The type thus
restored differs from the domed cross church in that the cross arms do
not extend to the outer walls, and from the domed basilica in that the
western dome arch is treated in a similar manner to the lateral arches.
To this type the term 'ambulatory church' may be applied.

Adjoining the west end of the church is the fine cloister of the Teke of
dervishes, probably on the lines of the old monastery. All the columns
around the court are Byzantine, and one of them bears the inscription:
the (column) of, Theophane--[Greek: he tes Theophanes] (Fig. 69). In the
south wall is built a beautiful Byzantine doorway having jambs and
lintel decorated on the face with a broad undercut scroll of flat leaves
and four-petalled flowers, running between two rows of egg and dart,
while on the intrados are two bands of floral ornaments separated by a
bead moulding. One of the bands is clearly a vine scroll. The method
employed here, of joining leaves to a centre so as to form spiral
rosettes, is found also on some of the small capitals in S. Sophia.
Similar rosettes appear in the decoration of the doorway to the Holy
Sepulchre on the ivory in the Trivulce collection at Milan.[178]
