The architecture of Mesopotamia is the ancient architecture of the region of the Tigris–Euphrates river system (also known as Mesopotamia), encompassing several distinct cultures and spanning a period from the 10th millennium BC, when the first permanent structures were built, to the 6th century BC. Among the Mesopotamian architectural accomplishments are the development of urban planning, the courtyard house, and ziggurats. No architectural profession existed in Mesopotamia; however, scribes drafted and managed construction for the government, nobility, or royalty. The Mesopotamians regarded 'the craft of building' as a divine gift taught to men by the gods as listed in ''me'' 28. ==Building materials== Sumerian masonry was usually mortarless although bitumen was sometimes used. Brick styles, which varied greatly over time, are categorized by period.〔Harmansah, 2007〕 *Patzen 80×40×15 cm: Late Uruk period (3600–3200 BCE) *Riemchen 16×16 cm: Late Uruk period (3600–3200 BCE) *Plano-convex 10x19x34 cm: Early Dynastic Period (3100–2300 BCE) Since rounded bricks are somewhat unstable, Mesopotamian bricklayers would lay a row of bricks perpendicular to the rest every few rows. The advantages to plano-convex bricks were the speed of manufacture as well as the irregular surface which held the finishing plaster coat better than a smooth surface from other brick types. Because these bricks were sun baked, buildings eventually deteriorated. They were periodically destroyed, leveled, and rebuilt on the same spot. This planned structural life cycle gradually raised the level of cities, so that they came to be elevated above the surrounding plain. The resulting hills are known as tells, and are found throughout the ancient Near East. Civic buildings slowed decay by using cones of colored stone, terracotta panels, and clay nails driven into the adobe-brick to create a protective sheath that decorated the façade. Specially prized were imported building materials such as cedar from Lebanon, diorite from Arabia, and lapis lazuli from India. Babylonian temples are massive structures of crude brick, supported by buttresses, the rain being carried off by drains. One such drain at Ur was made of lead. The use of brick led to the early development of the pilaster and column, and of frescoes and enamelled tiles. The walls were brilliantly colored, and sometimes plated with zinc or gold, as well as with tiles. Painted ''terra-cotta'' cones for torches were also embedded in the plaster. Assyria, imitating Babylonian architecture, also built its palaces and temples of brick, even when stone was the natural building material of the country – faithfully preserving the brick platform, necessary in the marshy soil of Babylonia, but little needed in the north. As time went on, however, later Assyrian architects began to shake themselves free of Babylonian influence, and to use stone as well as brick. The walls of Assyrian palaces were lined with sculptured and coloured slabs of stone, instead of being painted as in Chaldea. Three stages may be traced in the art of these ''bas-reliefs'': it is vigorous but simple under Ashurnasirpal II, careful and realistic under Sargon II, and refined but wanting in boldness under Ashurbanipal. In Babylonia, in place of the ''bas relief'', there is greater use of three-dimensional figures in the round – the earliest examples being the statues from Girsu, that are realistic if somewhat clumsy. The paucity of stone in Babylonia made every pebble precious, and led to a high perfection in the art of gem-cutting. Two seal-cylinders from the age of Sargon of Akkad are among the best examples of their kind. One of the first remarkable specimens of early metallurgy to be discovered by archaeologists is the silver vase of Entemena. At a later epoch, great excellence was attained in the manufacture of such jewellery as earrings and bracelets of gold. Copper, too, was worked with skill; indeed, it is possible that Babylonia was the original home of copper-working. The people were famous at an early date for their embroideries and rugs. The forms of Assyrian pottery are graceful; the porcelain, like the glass discovered in the palaces of Nineveh, was derived from Egyptian models. Transparent glass seems to have been first introduced in the reign of Sargon. Stone, clay and glass were used to make vases, and vases of hard stone have been dug up at Girsu similar to those of the early dynastic period of Egypt. The Tigris-Euphrates plain lacked minerals. Sumerian structures were made of plano-convex mudbrick, not fixed with mortar or cement. Mud-brick buildings eventually deteriorate, so they were periodically destroyed, leveled, and rebuilt on the same spot. This constant rebuilding gradually raised the level of cities, which thus came to be elevated above the surrounding plain. The resultant hills, known as tells, are found throughout the ancient Near East. The study of ancient Mesopotamian architecture is based on available archaeological evidence, pictorial representation of buildings, and texts on building practices. According to Archibald Sayce, the primitive pictograms of the Uruk period era suggest that "Stone was scarce, but was already cut into blocks and seals. Brick was the ordinary building material, and with it cities, forts, temples and houses were constructed. The city was provided with towers and stood on an artificial platform; the house also had a tower-like appearance. It was provided with a door which turned on a hinge, and could be opened with a sort of key; the city gate was on a larger scale, and seems to have been double. ... Demons were feared who had wings like a bird, and the foundation stones – or rather bricks – of a house were consecrated by certain objects that were deposited under them."〔Sayce, Rev. A. H., Professor of Assyriology, Oxford, ("The Archaeology of the Cuneiform Inscriptions" ), Second Edition-revised, 1908, Society for Promoting Christian Knowledge, London, Brighton, New York; at pages 98–100 (Not in copyright )〕 Scholarly literature usually concentrates on the architecture of temples, palaces, city walls and gates, and other monumental buildings, but occasionally one finds works on residential architecture as well. Archaeological surface surveys also allowed for the study of urban form in early Mesopotamian cities. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Architecture of Mesopotamia」の詳細全文を読む スポンサード リンク
