Ostrich Eggshell Beads
Ostrich eggshell beads, considered among the earliest ornaments created by ''Homo sapiens'', represent some of the most ancient fully manufactured beads. Archaeologists have traced their origins back to the Late Pleistocene, with evidence suggesting they were crafted as early as 75,000 years ago in Africa. Certain populations continue to produce and utilize these beads in contemporary times. Ostrich eggshell beads likely originated from eastern Africa. They appear in the archaeological record all throughout Africa in a variety of contexts, including those of foraging, herding, and farming societies. They are particularly well-represented in the archaeological record of the Holocene, and are well-studied in eastern and southern Africa. They can be useful to archaeologists as a way to study symbolic meanings, the creation and maintenance of social identities, exchange, and can even be used to radiocarbon date sites. They also appear in the archaeological record of Asia, with some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OES Holocene Africa - Miller Et Al 2019
Oes or owes were metallic "O" shaped rings or eyelets sewn on to clothes and furnishing textiles for decorative effect in England and at the Elizabethan and Jacobean court. They were smaller than modern sequins. Making and metals Robert Sharp obtained a patent to make gold oes and spangles (another early variety of sequin) in 1575. They were also made from silver and copper. Oes were made either from rings of wire wound around a dowel, or by punching flat rings out of a sheet of metal. Policy makers worried about the supply of precious metal bullion and restricted the making of gold and silver oes and similar products by patent to the Company of Wire Drawers. In July 1624 their manufacture was forbidden for a time. Some London hat band makers were prosecuted and fined in 1631 for the fraud of using gilt copper oes and claiming their wares employed only gold oes and thread. Imitation silver or gold oes sold openly were called "counterfeit oes" or "Alchemy oes", and appear as "Olca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pillar Cemetery
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term ''column'' applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a '' post''. Supports with a rectangular or other non-round section are usually called ''piers''. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. In architecture, "column" refers to such a structural element that also has certain proportional and decorative featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beadwork
Beadwork is the art or craft of attaching beads to one another by stringing them onto a thread or thin wire with a sewing or beading needle or sewing them to cloth. Beads are produced in a diverse range of materials, shapes, and sizes, and vary by the kind of art produced. Most often, beadwork is a form of personal adornment (e.g. jewelry), but it also commonly makes up other artworks. Beadwork techniques are broadly divided into several categories, including loom and off-loom weaving, stringing, bead embroidery, bead crochet, bead knitting, and bead tatting. Ancient beading The art of creating and utilizing beads is ancient, and ostrich shell beads discovered in Africa can be carbon-dated to 10,000 BC. Faience beads, a type of ceramic created by mixing powdered clays, lime, soda, and silica sand with water until a paste forms, then molding it around a stick or straw and firing until hard, were notably used in ancient Egyptian jewelry from the First Dynasty (beginning in t ...

San People
The San peoples (also Saan), or Bushmen, are members of various Khoe, Tuu, or Kxʼa-speaking indigenous hunter-gatherer cultures that are the first cultures of Southern Africa, and whose territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho and South Africa. In 2017, Botswana was home to approximately 63,500 San people (roughly 2.8% of the population) making it the country with the highest number of San people. Definition The term "San" has a long vowel and is spelled Sān (in Khoekhoegowab orthography). It is a Khoekhoe exonym with the meaning of "foragers" and was often used in a derogatory manner to describe nomadic, foraging people. Based on observation of lifestyle, this term has been applied to speakers of three distinct language families living between the Okavango River in Botswana and Etosha National Park in northwestern Namibia, extending up into southern Angola; central peoples of most of Namibia and Botswana, extending into Zambia and Zimbabwe ...

Social Network
A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics. Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Georg Simmel authored early structural theories in sociology emphasizing the dynamics of triads and "web of group affiliations". Jacob Moreno is credited with developing the first sociograms in the 1930s to study interpersonal relationships. These approaches were mathematically formalize ...

Ethnographic
Ethnography (from Greek ''ethnos'' "folk, people, nation" and ''grapho'' "I write") is a branch of anthropology and the systematic study of individual cultures. Ethnography explores cultural phenomena from the point of view of the subject of the study. Ethnography is also a type of social research that involves examining the behavior of the participants in a given social situation and understanding the group members' own interpretation of such behavior. Ethnography in simple terms is a type of qualitative research where a person puts themselves in a specific community or organization in attempt to learn about their cultures from a first person point-of-view. As a form of inquiry, ethnography relies heavily on participant observation—on the researcher participating in the setting or with the people being studied, at least in some marginal role, and seeking to document, in detail, patterns of social interaction and the perspectives of participants, and to understand these i ...

Hunter-gatherer
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local sources, especially edible wild plants but also insects, fungi, honey, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish), roughly as most animal omnivores do. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups in ...

Kalahari
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for , covering much of Botswana, and parts of Namibia and South Africa. It is not to be confused with the Angolan, Namibian, and South African Namib coastal desert, whose name is of Khoekhoegowab origin and means "vast place". Etymology ''Kalahari'' is derived from the Tswana word ''Kgala'', meaning "the great thirst", or ''Kgalagadi'', meaning "a waterless place"; the Kalahari has vast areas covered by red sand without any permanent surface water. History The Kalahari Desert was not always a dry desert. The fossil flora and fauna from Gcwihaba Cave in Botswana indicates that the region was much wetter and cooler at least from 30 to 11 thousand BP (before present) especially after 17,500 BP. Geography Drainage of the desert is by dry black valleys, seasonally inundated pans and the large salt pans of the Makgadikgadi Pan in Botswana and Etosha Pan in Namibia. The only permanent river, ... [...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] |
