The arrival of the Arabs
When the Arabs arrived in Khurasan and Transoxania
they found few towns. The population lived mainly in the countryside,
where there were scattered estates with the fortified kushks
(castles) of major and minor dihqn (landowner)-suzerains
and adjacent settlements. The ancient towns had either shrunk in
size (Samarkand, Merv, Termez, Balkh) or been abandoned. The new
towns were few in number, and small (Panjikent).
Warfare was rife in the seventh and eighth centuries
and, as a consequence, there was a general decline in building activity.
This situation only changed in the ninth century, when the sphere
of influence of the caliphate finally took in the countries of Central
Asla and Islam became solidly established. The cAbbasids
relied on the local rulers, requiring only recognition of their
supreme authority and the levying of the kharj (land tax),
and did not interfere in the internal affairs of the newly established
states. One of the consequences of this policy was the rapid development
of towns from the ninth to the twelfth century and the general extension
of urban culture in Khurasan, Transoxania, Khwarazm and parts of
the Turkish lands to the north.
TOWN-PLANNING AND THE GROWTH OF TOWNS
The following typology for towns throughout this
region has been generally accepted by specialists. The original
pre-Islamic nucleus of the settlement was transformed
into an arg or kuhandiz (fortified citadel), next
to which lay the actual town, the shahristn, which was also
walled. Outside this wall lay the district of the tradesmen and
craftsmen, the rabad (suburb). Some towns do actually follow
this plan, but it is by no means in evidence everywhere and at all
times. In Samarkand, for example, in addition to the arg and
the shahristn (the site of Afrasiab), two other, adjoining,
urban areas took shape, the shahr-i darn (inner town) and
the shahr-i birn (outer town), beyond which lay the rabad.
Merv possessed an old shahristn (Gavur-Qalca)
but a new one (Sultan Qalca) was built, to which the
main activities of urban life were transferred. A new fortified
shahriyr-arg (town with a citadel) developed there. Immediately
to the north and south lay two walled rabads, which extended
beyond their enclosing walls. The towns in the northern regions
of Central Asia, where the population was predominantly nomadic,
were quite small, with an arg and a shahristn. The
outer rabads were small and at times non-existent because
of the danger of attacks by the nomads.
The shahristns of the medieval towns of
Central Asia which were established at that time were strictly rectangular
in shape (e.g. Sultan-Qalca at Merv), but where the town
had developed in an uncontrolled fashion around an earlier settlement
(Balkh, Samarkand) their outline was irregular. They had several
gates, located on the main roads into the town. In Merv there were
four, in Samarkand six and in Bukhara seven.
One of the principal concerns of town-planners
at this time was defence. The towns were surrounded by ditches and
enclosed by walls, sometimes by a double wall (Mashhad-i Misriyan,
the earlier Dihistan). The walls were flanked by rounded towers
from which radial fire could be directed. Particular importance
was attached to the defensive capability of the gates: towers rose
on either side of the gates and on top of the towers were military
and surveillance platforms. Often, a drawbridge was erected to span
the ditch.
There was practically nothing regular about the
internal planning of the towns. To a certain extent, it was determined
by the main streets, which ran from one gate to another, forming
intersections at the town centre. They did not run in straight lines
and there were sharp bends. These arteries determined the location
of the towns focal points with small squares here and there
and the main bazaars stretching along the streets, either uncovered
or with light awnings, and sometimes with an extensive covering
of vaulted and domed roofs. Between these main streets lay guzrs
(Persian, lanes) or mahalls (Arabic, quarters), criss-crossed
by a tangled web of alleys, in which living accommodation, the local
mosque, the maktab (elementary school) and the public water
cistern were to be found and which preserved the communal life-style.
The different trades and crafts had their own special quarters:
those with harmful side-effects such as potteries and iron-foundries
were located in the rabads whereas the clean
trades (sewing and embroidery, jewellery, etc.) were to be found
inside the shahristn.
CONSTRUCTION MATERIALS
The architecture of the period reflected the advances
which had been made, in particular in construction engineering.
Unbaked brick and pis (rammed earth) remained the basic
wall-building materials until the tenth century, with wooden roofing
or else unbaked vaulting and domes. From the tenth century, baked
brick with a high-strength ganch (gypsum) mortar was increasingly
employed in monumental architecture. Its use as a building material
for walls and vaulted, domed structures provided architects with
new ways of putting their ideas into practice, enabling them to
devise original solutions in terms of space and volume. As a more
costly building material and one whose use required great skill,
it was essentially employed in monumental, mainly religious, architecture
and in certain structures which had to be waterproof (bridge piers
and abutments, bathhouses). It is noteworthy that unbaked brick
and reinforced pis structures continued to be used, as in
earlier times, in secular buildings, even in the palaces of the
rulers, not to speak of the living accommodation and workshops for
the general population. This is not just because they were easy
and cheap to make, but because clay is a poorer conductor of heat
than baked brick, providing protection from the heat in summer and
the cold in winter. Baked brick was, however, used for Islamic religious
structures, which were built to last.
ARCHITECTURAL ORNAMENTATION
The development and refinement of various forms
of architectural ornament continued from the ninth to the twelfth
century. Decorative brickwork made of regular or shaped bricks,
wood and ganch carving, passed down from pre-Islamic times
but with different ornamental motifs, carved terracotta and, from
the twelfth century, the appearance of glazed brick and the use
of glazes (pale blue, dark blue, white) to pick out decorative motifs
on carved terracotta: such was the variety of decorative techniques
which, in interiors, also included decorative painting. The decorative
motifs were varied but girih (geometric designs forming a
knot) predominated. Their development was linked to the spectacular
advances made in mathematical science in the medieval East, which
were the basis for Central Asian architects and decorative
craftsmens use of applied geometry. Stylized plant decoration
was co-ordinated with girih; and Arabic epigraphy also acquired
a special significance, being used for Quranic texts and other
inscriptions containing historical information relating to influential
figures and to the period at which the building was constructed.
These inscriptions, which were executed in the geometric Kufic or
flowing, cursive naskh scripts, were an important decorative
element in the design of the building.
The palaces of the rulers were distinguished by
their large proportions and wealth of artistic decoration. In the
Samanid palace in Samarkand (the site of Afrasiab), archaeologists
have uncovered several halls in which the walls were decorated with
carving in ganch. The motifs are large geometric figures
enclosing fine plant decoration. The eleventh-twelfth-century palace
in the shahriyr-arg at Merv is on a square plan with a small
interior courtyard surrounded by both large and small rooms, but
only small decorative fragments have been found. The decoration
is extremely rich, however, in the palace of the rulers of Termez
at the same period. A courtyard is also the key to the organization
of this palaces plan. There is a portal at the entrance to
the courtyard, on both sides of which ire a number of differentiated
rooms. Along its axis runs a five-columned portico leading to an
audience hall. Within the hall a central area was marked out, at
the far end of which stood the throne. Surrounding the central area
and separated from it by columns was an ambulatory. The roofs were
vaulted. Walls, columns and vaults were covered in the most elaborate
ganch carving in which girih, in all its various forms,
has pride of place, although there are also heraldic motifs
a pair of lions facing each other with jaws locked together. Carved
ganch was also used in many decorative forms to embellish
the residences of the rich; outstanding examples were discovered
during the excavation of such houses at Merv, Nishapur and Samarkand.
BATHHOUSES
Among works of civil architecture, mention should
be made of the public bathhouses. The remains of eleventh-century
baths have been discovered in Taraz (a town in the area of northern
Turkistan) and in Nasa (Khurasan). Premises have been found there
with cisterns for hot and cold water and a system of underground
flues for heating the floors with hot air. It is noteworthy that
there are traces of ornamental painting, employing special water-resistant
paints, on the walls of both bathhouses.
CARAVANSERAIS
Large market buildings were erected on the main
streets in towns. The caravanserais formed a special category. They
were to be found in towns, especially towns on the major caravan
routes on which most of them were located. The builders task
was to construct a safe shelter for caravans which had been travelling
for many days, providing protection from attack by robbers for the
travellers and for the animals that had carried them and their wares,
and pleasant conditions for their stay. Hence the solid defences
of the caravanserais: high walls, reinforced entrance gates, corner
watch-towers and, inside, a well-thought-out division of space to
provide for sojourn and rest. Caravanserais were often also used
as ribts (defence posts) for the billeting en route
of the rulers forces.
RELIGIOUS STRUCTURES
Particular attention was devoted in the eleventh
and twelfth centuries to the construction of religious buildings,
especially mosques. The first mosques appeared in Khurasan and Transoxania
immediately after their conquest by the Arabs: direct evidence of
this is provided by the Arab historians and geographers. The earliest
surviving mosques date from the ninth and early tenth centuries.
One of these is the Diggaron village mosque at the qishlaq
(winter station) of Khazar in the Bukhara oasis; two others are
the local Naw Gunbad mosque on the outskirts of Balkh and the Chahar
Sutun in Termez. Characteristic features of these mosques are their
square plan and brick supporting pillars. The pillars are connected
to the walls by arches and corner pendentives effect the transition
to the small domes. The number of columns varies (four, six, nine),
as does the number of domes, but the basic plan remains the same.
The mihrb (prayer niche) is located on the qibla
wall (which indicates the direction of worship towards Mecca).
In a special category was the commemorative mosque,
erected beside the tomb of a revered religious person such as a
sayyid (descendant of the Prophet) or one of the cAlids,
or the pirs of Sufi orders, all of them figures who tended
to become canonized with the passage of time. An example of this
type is the mosque of Talkhatan-Baba near the settlement of the
same name in the valley of the Murghab. Providing something of an
architectural setting for the tomb, it is a rectangular building
divided into three sections. The central section is covered by a
large dome, and all the faades are faced with shaped bricks.
An essential structure in any mosque is the minaret
(minr) from which the faithful are called to ritual prayers.
In this period it was a free-standing tower at the corner of the
mosque, and the minarets of large Friday mosques were particularly
tall. Minarets in Central Asia are typically round in section, tapering
towards the top, but there are a number of variations. At times
it is simply a tall shaft, crowned by a multi-arched rotunda for
the muezzin pronouncing the adhn (call to prayer): the shaft
itself is divided by concentric ornamental bands (the Kalyan mosque
in Bukhara, see Fig. 1), the minaret at Vabkent,
the two minarets at Dihistan, Brns tower at
Balasaghun, the minaret at Uzgend). Another version, with the shaft
resting on an octagonal base, is divided vertically by close-set
fluted half-columns and has a second section (the minaret at Jarkurgan
by the architect cAli b. Muhammad al-Sarakhs) or an
even more complex structure consisting of three sections, each of
which culminates in a stalactite configuration (the minaret of Jam).
They are built in baked brick, which is also used for decorative
effect. These constructions stand as high as 48 m (Kalyan) or even
60 in (Jam).
ARCHITECTURAL PROPORTIONS
It has been established from an analysis of medieval
architectural monuments in Central Asia that their horizontal and
vertical measurements and proportions are based on mathematical
laws. There are two variants. In some cases they are a multiple
of a gaz (linear unit), which was a sort of architectural
module. But geometric proportions were more frequently employed:
ratios of the square and its diagonal were most common, although
other ratios were also used, such as the sides of a triangle or
the golden mean. Their use was due to mathematical progress in the
Near and Middle East and, in particular, the development of the
applied geometry techniques which were assimilated and widely employed
by architects, These were responsible for the harmonious horizontal
and vertical proportions of the buildings erected, both as composite
units and as separate parts.
