Dotted Wavy Line And Wavy Line Pottery
Dotted wavy line and wavy line pottery has been discovered in archaeological sites across North and Eastern Africa. These pieces are some of the oldest examples of pottery, made by hunter-fisher-gatherers between five and ten thousand years ago. The pieces of pottery are characterized by their namesake solid wavy lines and dotted wavy lines. Background In the later Holocene, fishers and hunter-gatherers in Northern Africa created pottery that was characterized by decorative incised and dotted wavy lines. These pieces were created between ten thousand and five thousand years ago, making them some of the oldest known pieces of African pottery. These people lived during the African humid period in semi-permanent and permanent settlements around the numerous bodies of water that existed in the now-arid regions of North and East Africa. These settlements are characterized by the discovery of wavy line pottery found in conjunction with barbed bone points, which are adaptations for an "a ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Turkana
Lake Turkana (), formerly known as Lake Rudolf, is a lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. It is the world's largest permanent desert lake and the world's largest alkaline lake. By volume it is the world's fourth-largest salt lake after the Caspian Sea, Issyk-Kul, and Lake Van (passing the shrinking South Aral Sea), and among all lakes it ranks 24th. Lake Turkana is now threatened by the construction of Gilgel Gibe III Dam in Ethiopia due to the damming of the Omo river which supplies most of the lake's water. Although the lake commonly has been —and to some degree still is— used for drinking water, its salinity (slightly brackish) and very high levels of fluoride (much higher than in fluoridated water) generally make it unsuitable, and it has also been a source of diseases spread by contaminated water. Increasingly, communities on the lake's shores rely on underground springs for drinking water. The same c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Archaeology
Africa has the longest record of human habitation in the world. The first hominins emerged 6-7 million years ago, and among the earliest anatomically modern human skulls found so far were discovered at Omo Kibish, Jebel Irhoud, and Florisbad. European archaeology, as well as that of North Africa, is generally divided into the Stone Age (comprising the Lower Paleolithic, the Middle Paleolithic, the Upper Paleolithic, the Mesolithic, and the Neolithic), the Bronze Age, and the Iron Age. For Africa south of the Sahara, African archaeology is classified in a slightly different way, with the Paleolithic generally divided into the Early Stone Age, the Middle Stone Age, and the Later Stone Age. After these three stages come the Pastoral Neolithic, the Iron Age and then later historical periods. Africa's prehistory has been largely ignored, with the exception of research into early human evolution. However, it is overseen by the PanAfrican Archaeological Association, whose members ...

Ancient Pottery
Ancient history is a time period from the beginning of writing and recorded human history to as far as late antiquity. The span of recorded history is roughly 5,000 years, beginning with the Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500. The three-age system periodizes ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages varies between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was already exponentially increasing due to the Neolithic Revolution, which was in full progress. While in 10,000 BC, the world population stood at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Pottery
African folk art consists of a variety of items: household objects, metal objects, toys, textiles, masks, and wood sculpture. Most traditional African art meets many definitions of folk art generally, or at least did so until relatively recent dates. Metal objects Much African folk art consists of metal objects due in part to the cultural status of forging as a "process that is likened to the creation of life itself." While in the past ceremonial pieces were exchanged as part of social rituals (i.e. marriage), today in Senegal, metal objects are recycled as utilitarian African folk art. Jewellery In West Africa, the Asante are popular for their crafts and trade in gold. For the people of Ghana, not only does the colour gold represent wealth and status but there is also belief that it is a protection to whoever wears it. Necklaces have been made of gold bells, disks, and cross-shaped beads for those to wear around the neck. In the Alkan culture, each of these elements are made b ...

Ancient Egyptian Pottery
Ancient Egyptian pottery includes all objects of fired clay from ancient Egypt. First and foremost, ceramics served as household wares for the storage, preparation, transport, and consumption of food, drink, and raw materials. Such items include beer and wine mugs and water jugs, but also bread moulds, fire pits, lamps, and stands for holding round vessels, which were all commonly used in the Egyptian household. Other types of pottery served ritual purposes. Ceramics are often found as grave goods. Specialists in ancient Egyptian pottery draw a fundamental distinction between ceramics made of Nile clay and those made of marl clay, based on chemical and mineralogical composition and ceramic properties. Nile clay is the result of eroded material in the Ethiopian mountains, which was transported into Egypt by the Nile. This clay has deposited on the banks of the Nile in Egypt since the Late Pleistocene by the flooding of the Nile. Marl clay is a yellow-white stone which occurs in li ...

Temper (pottery)
A temper is a non-plastic material added to clay to prevent shrinkage and cracking during drying and firing of vessels made from the clay. Tempers may include: *Bone; *Chaff; *Charcoal; *Ground schist; *Wood ash; * Grit; *Sand or crushed sandstone; *Crushed limestone; *Crushed igneous rocks, such as volcanic rock, feldspar, or mica; *Grog; *Plant fiber; *Horse manure (dried and sifted); *Crushed mollusc shells (including fossilized) (see Shell tempering in the Mississippian culture); and *Freshwater sponge spicules. Some clays used to make pottery do not require the addition of tempers. Pure kaolin clay Kaolinite ( ) is a clay mineral, with the chemical composition Al2 Si2 O5( OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica () linked through oxygen atoms to one octahedra ... does not require tempering. Some clays are self-tempered, that is, naturally contain enough mica, sand, or sponge spicules that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesolithic
The Mesolithic (Greek: μέσος, ''mesos'' 'middle' + λίθος, ''lithos'' 'stone') or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and Western Asia, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in Southwest Asia (the Epipalaeolithic Near East) roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa. The type of culture associated with the Mesolithic varies between areas, but it is associated with a decline in the group hunting of large animals in favour of a broader hunter-g ...

Atbara
Atbara (sometimes Atbarah) ( ar, عطبرة ʿAṭbarah) is a city located in River Nile State in northeastern Sudan. Because of its links to the railway industry, Atbara is also known as the "Railway City'. As of 2007, its population is 111,399. History The confluence of the Nile and its most northern tributary, the Atbarah River (Bahr-el-Aswad, or Black River) was a strategic location for military operations. in the year 1619 Atbara was conquered and sacked by forces of the Ethiopian Empire. In the Battle of Atbara, fought on 8 April 1898 near Nakheila, on the north bank of the river, Lord Kitchener's Anglo-Egyptian army defeated the Mahdist forces, commanded by Amir Mahmud Ahmad. Kitchener's strengthened position led to a decisive victory at the Battle of Omdurman on 2 September 1898, giving the British control over the Sudan. The town was the centre of the Sudanese railway industry. Few trains are made here now and rail traffic is much reduced. The original stat ...

North Africa
North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritania in the west, to Egypt's Suez Canal. Varying sources limit it to the countries of Algeria, Libya, Morocco, and Tunisia, a region that was known by the French during colonial times as "''Afrique du Nord''" and is known by Arabs as the Maghreb ("West", ''The western part of Arab World''). The United Nations definition includes Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, and the Western Sahara, the territory disputed between Morocco and the Sahrawi Republic. The African Union definition includes the Western Sahara and Mauritania but not Sudan. When used in the term Middle East and North Africa (MENA), it often refers only to the countries of the Maghreb. North Africa includes the Spanish cities of Ceuta and Melilla, and plazas de s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Thermoluminescence Dating
Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated (lava, ceramics) or exposed to sunlight (sediments). As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating. The technique has wide application, and is relatively cheap at some US$300–700 per object; ideally a number of samples are tested. Sediments are more expensive to date. , University of Wollongong, Australia [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
