It is in its use for domes and vaults that
muqarnas was to have its most significant impact.
By providing a diffused method of transition from
flat to curved, muqarnas zones of transition were
able to break down the distinction between vertical
and curved, domed and horizontal. The best
examples of this can be seen in conical domes such
as that at Natanz in Iran where the roof emerges
not as a hemispherical dome but as a multi-faceted
prism-like series of surfaces.
The almost universal adoption of muqarnas as
architectural decoration meant that it was also
adapted for woodwork such as mosque furniture.
The minbar of Nur al-Din built for the Aqsa Mosque
in Jerusalem had three bands of tiered muqarnas on
a canopy above the foot of the stairs.
In Iraq, Iran and the eastern Islamic world the
most suitable materials for muqarnas construction
were plaster and baked brick. Both materials have
the advantage of being light whilst bricks have the
additional advantage of being made to a standard
dimension which is useful when repeating the
complex geometric alignments necessary for
muqarnas. Plaster also has the advantage that it can
easily be decorated by carving or painting. In Syria
and Egypt the first muqarnas domes were made from
plaster suspended from a wooden frame within an
outer dome made out of stone. The most famous
example of this technique is the dome in Nur al-Din’s
maristan built in 1154. Later muqarnas stone domes
were made, the best examples of which belong to
fifteenth-century Egypt.
The first muqarnas was made purely out of
interlocking cut niches but fairly early on ‘dripping’
stalactites were developed. These are thin downward
projections from the cut side of the niche which give
the illusion of arches suspended in mid-air. These
stalactite niches are some of the most elaborate form
of muqarnas which defy attempts at two-
dimensional representation.
There are several theories about the origins of
muqarnas. Generally the decorative origin and
function is favoured over the suggestion that
muqarnas was the solution to a particular structural
problem. The reason for this conclusion is that some
of the earliest examples of muqarnas found were
decorative plaster bands, although equally early are
exam-pies of muqarnas squinches from Egypt.
Whilst certainly muqarnas did have a decorative
function, from the beginning its early and frequent
association with domes and pendentives suggests
that the form had structural associations. The tiered
form of muqarnas means that the thrust of the dome
could be directed downwards into the corner of a
building without adding the extra weight of a
pendentive. On the other hand muqarnas squinches
are a way of providing a greater span without having
to build large heavy arches. In general muqarnas
tends to blur the distinction between squinch and
pendentive and provides a more subtle transition
from square to octagon. A view which combines both
decorative and structural functions suggests that the
origins of muqarnas may be found in Islamic
theology which promotes an occasionalist view of
the universe whereby the continued existence of any-
thing is dependent on the will of God. Muqarnas is
then a way of expressing this view of the universe
where the dome appears to stand without visible
support.
