Pre-Pottery Neolithic A
Pre-Pottery Neolithic A (PPNA) denotes the first stage of the Pre-Pottery Neolithic, in early Levantine and Anatolian Neolithic culture, dating to years ago, that is, 10,000–8,800 BCE. Archaeological remains are located in the Levantine and Upper Mesopotamian region of the Fertile Crescent. The time period is characterized by tiny circular mud-brick dwellings, the cultivation of crops, the hunting of wild game, and unique burial customs in which bodies were buried below the floors of dwellings. The Pre-Pottery Neolithic A and the following Pre-Pottery Neolithic B (PPNB) were originally defined by Kathleen Kenyon in the type site of Jericho (Palestine). During this time, pottery was not yet in use. They precede the ceramic Neolithic ( Yarmukian). PPNA succeeds the Natufian culture of the Epipaleolithic ( Mesolithic). Settlements PPNA archaeological sites are much larger than those of the preceding Natufian hunter-gatherer culture, and contain traces of communal struc ...

Neolithic Revolution
The Neolithic Revolution, or the (First) Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible. These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed. This new knowledge led to the domestication of plants into crops. Archaeological data indicates that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the geological epoch of the Holocene 11,700 years ago. It was the world's first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a downturn in the quality of human nutrition compared with that obtained previously from foraging. The Neolithic Revolution involved far more than the adopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon 14
Carbon-14, C-14, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz Kurie in 1934. There are three naturally occurring isotopes of carbon on Earth: carbon-12 (), which makes up 99% of all carbon on Earth; carbon-13 (), which makes up 1%; and carbon-14 (), which occurs in trace amounts, making up about 1 or 1.5 atoms per 1012 atoms of carbon in the atmosphere. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5,730 ± 40 years. Carbon-14 decays into nitrogen-14 () through beta decay. A gram of ...

Gesher (archaeological Site)
Gesher is an archaeological site located on the southern bank of Nahal Tavor, near kibbutz Gesher in the central Jordan Valley of Israel. It bears signs of occupation from two periods, the very early Neolithic and the Middle Bronze Age. The site was first excavated between 1986 and 1987 by Yosef Garfinkel of the Hebrew University of Jerusalem and between 2002 and 2004 by Susan Cohen of Montana State University. The average of 4 radiocarbon dating results suggested inhabitation of the settlement around 8000 BC. During the Pre-Pottery Neolithic A the site was a small village composed of a few rounded structures. Typical flint finds included a high number of el-Khiam points which Garfinkel argued, along with the relatively early date could class Gesher as a Khiamian site. One outstanding discovery, unknown from any other Neolithic site of the period in the Near East, is a workshop for the production of basalt artifacts. The workshop produced basalt axes and various other tools ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hearth
A hearth () is the place in a home where a fire is or was traditionally kept for home heating and for cooking, usually constituted by at least a horizontal hearthstone and often enclosed to varying degrees by any combination of reredos (a low, partial wall behind a hearth), fireplace, oven, smoke hood, or chimney. Hearths are usually composed of masonry such as brick or stone. For centuries, the hearth was such an integral part of a home, usually its central and most important feature, that the concept has been generalized to refer to a homeplace or household, as in the terms "hearth and home" and "keep the home fires burning". In the modern era, since the advent of central heating, hearths are usually less central to most people's daily life because the heating of the home is instead done by a furnace or a heating stove, and cooking is instead done with a kitchen stove/range (combination cooktop and oven) alongside other home appliances; thus many homes built in t ...

Mudbrick
A mudbrick or mud-brick is an air-dried brick, made of a mixture of loam, mud, sand and water mixed with a binding material such as rice husks or straw. Mudbricks are known from 9000 BCE, though since 4000 BCE, bricks have also been fired, to increase their strength and durability. In warm regions with very little timber available to fuel a kiln, bricks were generally sun-dried. In some cases, brickmakers extended the life of mud bricks by putting fired bricks on top or covering them with stucco. Ancient world The history of mudbrick production and construction in the southern Levant may be dated as far back to the Pre-Pottery Neolithic A (e.g., PPNA Jericho). These sun dried mudbricks, also known as adobe or just mudbrick, were made from a mixture of sand, clay, water and frequently temper (e.g. chopped straw and chaff branches), and were the most common method/material for constructing earthen buildings throughout the ancient Near East for millennia. Unfired mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrazzo
Terrazzo is a composite material, poured in place or precast, which is used for floor and wall treatments. It consists of chips of marble, quartz, granite, glass, or other suitable material, poured with a cementitious binder (for chemical binding), polymeric (for physical binding), or a combination of both. Metal strips often divide sections, or changes in color or material in a pattern. Additional chips may be sprinkled atop the mix before it sets. After it is cured it is ground and polished smooth or otherwise finished to produce a uniformly textured surface. "Terrazzo" is also often used to describe any pattern similar to the original terrazzo floors. History Terrazzo proper Although the history of terrazzo can be traced back to the ancient mosaics of Egypt, its more recent predecessors come from Italy. The form of terrazzo used today derives partly from the 18th century ''pavimento alla Veneziana'' (Venetian pavement) and the cheaper ''seminato.'' ''Pavimento alla Venezi ...

Tower Of Jericho
The Tower of Jericho is an stone structure, built in the Pre-Pottery Neolithic A period around 8000 BCE. It is considered the world’s first stone building, and possibly the world's first work of monumental architecture. The ancient wall of Jericho had been discovered by John Garstang during the excavations of 1930 to 1936, which he suggested were those described in the Book of Joshua in the Bible and dated to around 1400 BCE. Kathleen Kenyon discovered the tower built against the wall inside the town during excavations between 1952 and 1958. Kenyon provided evidence that both constructions dated to much earlier, to the Neolithic, which is the latest part of the Stone Age, and were part of an early proto-city. The tower highlights the importance of Jericho for the understanding of settlement patterns in the Sultanian period in the Southern Levant. Structure The tower was constructed using undressed stones, with an internal staircase of twenty-two steps. Conical in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reliefs Of Animals, Göbekli Tepe Layer III, Circa 9000 BCE
Relief is a sculptural method in which the sculpted pieces are bonded to a solid background of the same material. The term ''relief'' is from the Latin verb ''relevo'', to raise. To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood ( relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires a lot of chiselling away of the background, which takes a long time. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs ...

Calibrated Carbon 14 Dates For Gesher As Of 2013
In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, a sound tone, or a physical artifact, such as a meter ruler. The outcome of the comparison can result in one of the following: * no significant error being noted on the device under test * a significant error being noted but no adjustment made * an adjustment made to correct the error to an acceptable level Strictly speaking, the term "calibration" means just the act of comparison and does not include any subsequent adjustment. The calibration standard is normally traceable to a national or international standard held by a metrology body. BIPM Definition The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the fol ...

Climate And Post-Glacial Expansion In The Near East
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature ...
