The use of mud bricks dates back thousands of
years, and has been used by most cultures including Sumerians. Depending on the
regional resources, mud bricks may be fortified with many different materials,
including crushed rock or sea shells, or even hay or straw as in Sumeria.Even
though many buildings constructed of natural materials, only earth or mud ,
have stood up to now and these composite bricks made excellent building
materials. The first bricks were sun dried mud bricks. Fired bricks [baked
bricks]were found to be more resistant to harsher weather conditions, which
made them a much more reliable brick for use in permanent buildings, where mud
bricks would not have been sufficient such as -in drains, in paths, and in
other places where sun-dried mud-bricks would be eroded by running water.Fired
brick were also useful for absorbing any heat generated throughout the day,
then releasing it at night.
Mud works best for building where it's dry for
most of the year. If there's too
much rain, the walls of mud house could melt like ice cream on a warm
day. But mud bricks, which are baked hard in the sun or in a hot oven, can be
as strong and durable as stone.The earliest Sumerian houses were built of
bundles of reeds but after cities began to develop, sun baked mud brick was
used. These mud brick houses were more
permanent and larger than the reed dwellings.
Several examples of building plans have been
found on clay tablets, showing that Mesopotamian buildings were often carefully
designed and that measured plans were often used in their construction. A
seated statue of Gudea, ruler of Lagash , is depicted with such a plan together
with a scale ruler on his knee.
Once Sumerians first made bricks by scooping
wet mud into a wooden frame,they built houses, palaces and temples using mud
bricks. However,builders only rarely fired their bricks to make them totally
hard. This meant that heavy rains and floods would usually deteriorate Sumerian
buildings.Hence They were periodically destroyed, leveled, and rebuilt on the
same spot.even using the same muds.Also they built dams & tanks using mud
bricks.It is surprised to note that sumerians even built kitchen with chimneys
before 6000 years[4000 BC] ago.
When they made bricks from mud,they made them
in two ways,The most popular one among sumerians is Abode bricks,which are made
of earth with a fairly high clay content and straw. This earth mix is cast in
open moulds onto the ground and then left to dry out only on sun light for
about one month.Other one is kiln-fired bricks.If too much clay in bricks,It
may cause severe cracking.Also cracking may occur if bricks dry too
quickly.Also If sand is more in bricks it may cause bricks to break easily into
pieces,because,the presence of too much sand will decrease the amount of
drying.
The houses in the sumerian cities were very
close together and In the poorer
sections, they would share walls like the townhouses. to cut down on
construction costs.On the other hand, In
the richer sections, the houses stood alone.The rich people, primarily the
priests and merchants lived in double stories dwellings, whereas the trader
people and craftsmen had single story houses.
All of the houses were clustered around the Ziggurat to make it easy to
get to the temple and to leave offerings to the gods. They were not well
ventilated and most had no windows. The lower section was used when protection
from the weather was necessary. However,
because of the hot nights, the top floor, which was open and without a roof was
used as sleeping and cooking quarters,ie people would cook and eat on the roof
of the house and sleep there.Wealthier Sumerians had homes with several rooms
and the house was built in the shape of a "U" with a garden in the
center. Most Sumerians spent their day in the garden as the inside was always
dark, damp and without proper ventilation.Evidence suggests that the houses
were white-washed on the inside and outside thus giving the homes a cleaner
look. Mesopotamian builders knew how to build arches and vaults and at times
used freestanding or attached columns.For prestige buildings more expensive
materials were often used, such as baked brick with bitumen mortar, timber
imported from the Lebanon and Amanus mountains, and stones often transported a
considerable distance, and the rooms were decorated with expensive
fittings,such as wall paintings, geometric mosaics, carved-stone orthostats, or
paneling in rare or aromatic wood or in ivory.
In human history,shelter comes after the food
in human needs.Ordinary Tamil people from India & srilanka had lived in hut
& small mud houses,while wealthier people lived in large mud houses with more facilities,some
are courtyard houses[quadrangular house],some what similar to sumerian houses mentioned above..As these early houses
were built with temporary or decomposable materials, no houses of these types
are survived to this date,other than few latter courtyard houses built out of
permanent materials.These houses have raised platforms ('thinnai') between the front wall and the road. A walk
way, a few inches above the level of the road, provides access to the main
entrance door from the road, divide the front "thinnai" into two
parts, one on either side of the entrance door.This walk way is called a
"Nadai" in Tamil, which means walk.Around the court yard which is
open to the sky, there are wide open spaces. These are multi-purpose areas and
accommodate most of the day to day and
occasional activities. However,These
traditional proto type plan, with the central court yard, had been dropped now.
In silapathikaram, puhar kandam Ilango Adigal described the city of
Puhar in details.Lines 7~9 in chapter
5,"Indra Vizha " says:"The village of Maruvurpakkam was near the
beach and had several terraced mansions and warehoused with windows shaped like
the eyes of the Deer."
Also in Pattinappalai,in many lines it
described a small city in sangam period
as:
"Women with bright brows, fine jewels
and deer-like delicate looks, dry food
in the wide front yards of their huge
houses," (20-22)
[அகல் நகர் – huge house/city, வியன் முற்றம் – wide yard,]
"There are many stables with strong
bulls in the front yards of fine houses
with cold water wells".(51-52)
[தண் கேணி – well with cold water,முற்றத்து – front yards],
"In the settlement where fishermen live,
small-roofed huts
surrounded
by long fishing rods resting on them
appear like memorial stones surrounded by
spears
stuck in the ground with rows of shields
hanging on them."(78-81)
[குறுங்கூரை – small roofs, குடி நாப்பண் – in the middle of a settlement]
bright lights in the mansions with tall
pillars.on the big streets near the seashore(111)
[நெடுங்கால் மாடத்து – mansions with tall columns, ஒள் எரி நோக்கி – looking at the bright lights],
beautiful towns with mansions with tall entries
and curved columns(261),
[ கொடுங்கால் மாடத்து – mansions with curved columns, நெடுங்கடை – tall entries, துவன்று – get together, ]
With excellent structural and natural
characteristics, clay,which built sumerian cities, now is and will remain the
most popular and trusted buidling material: Its unique synthesis protects
perfectly against moisture and frost and in addition, it is diffusible,
fire-resistant, resistant against UV rays and extremely durable.
