the main kerbs which are ornamented geometrically. Ornaments
are planar on this building which is taken as a steppingstone
with these features. There are walking lion figures
in profile on the spandrels. 23 Heads and tails of these figures
are ruined. The thin kerb surrounding the entrance niche
below the inscription cincture from three directions is floral
patterned.
It is written on a few inscription tablets in Alaeddin Mosque
in Konya that it was completed in the supervision of Atabeg
Ayaz in the period of Sultan Kayqubad the 1st in the year
617/1220. 24 Two colored marble material is used in the construction
of the portal. The lancet arch of the shallow niche
shaped portal is surrounded by intermingled semi-circles
combining in the full circle at the peak point of it. The spandrel
is decorated with bands forming a knot. Geometrical
dowels arranged with two colored stonework convey the
southern features to the Central Anatolia.
The portal of Twin Minaret Madrasa in Erzurum
and the ornament made by turquoise glost brick among the
bricks in the entrance of it. Octagonal housing is covered by
a pyramidal roof. There are rectangular framed collapsed areas
on every elevation. The entrance of the east elevation
can be reached by two-sided stairs. Capitalled pillars on the
sides of the flat lintelled entrance are placed on the lancet
arch surronding the geometrically ornamented pediment.
The moldings forming round-profiled zigzags and cornered
rims we see in Halifet Gazi Tomb (1145) 21 in Amasya can be
an example of local traditions. The entrance with a small basket
ornament niche is surrounded by a gradually shrunken
thin wreathed baguet which forms partly zigzag, partly cornered
bays and rims. It has an arched window above that
which is separated by a column in the middle. A thin zigzaged
molding surrounds the elevation externally.
Dar al Shifaa 22 which was built by Kaykaus the 1st in 1217 in
Sivas has a plan with a patio and two iwans. The other side
iwan which was supposed to be in the southern direction
was utilized as a tomb. The tomb elevation is ornamented
with geometrical patterns in faience mosaic technique with
the colors blue, navy blue, white and turquoise. Muqarnas
rows are increased on the portal where the intensive decoration
is, and rumi patterns are used on the thin kerbs around
Alaeddin Mosque in Nigde which is one of the few buildings
remain unchanged was built in 1223. 25 The chancel of
the mihrab of the structure with three naves towards the
kiblah wall is covered with three domes side by side. The
other parts are covered with a pointed barrel vault on eight
jambs in north south direction. The portal is located in the
east elevation but a little slided to north. The stone minaret is
in the northeastern corner. There is a main kerb on the portal
which is far taller than the housing walls but not much protruding,
and it is geometrically ornamented. The kerb on the
basket ornament niche formed by large muqarnas is also geometrically
ornamented and the artist inscription takes place
on both sides of the peak point. Next to these, there are
two ruined human heads with hair in plaits. The lancet kerb
above these which is around the basket ornamented spandrel
to surround the three-line inscription is dowel patterned.
The kerb above the obtuse arched entrance is, likewise,
dowel patterned. The floral patterns on the portal consist of
just a few rosettes on the spandrels and in muqarnas slots.
Its geometrical patterns and the planar engraving technique
show that it is a structure of the first period.
We see such a stonework that can't be found before or after
itself in the ornaments of the complex consisting of the
Ulu Mosque and the Dar al Shifaa in Divrigi which Ahmet
Shah of the Mengujekid and his wife Turan Melek Sultan
had Master Hurremshah of Ahlat build it in 1228-1229. 26
Four entrances one of which belonging to the Dar al Shifaa
were arranged as portals separately. The northern portal
is ornamented with large rumi patterns that almost has a
three dimensional look. This looks couldn't be acquired even
in the Sivas Madrasas (1271) with intense floral ornaments.
