Mound 34
Mound 34 is a small platform mound located roughly to the east of Monks Mound at Cahokia Mounds near Collinsville, Illinois. Excavations near Mound 34 from 2002 to 2010 revealed the remains of a copper workshop, although the one of a kind discovery had been previously found in the late 1950s by archaeologist Gregory Perino, but lost for 60 years. It is so far the only remains of a copper workshop found at a Mississippian culture archaeological site. Construction sequence From the Emergent Mississippian period (beginning approximately 800 CE) to the Stirling Phase (1000 to 1200 CE) the location was a village site with multiple houses, pit features, extensive midden deposits, a copper worskop, and a large structure (possibly as large as by ) with a centrally located hearth. Early in the Moorehead Phase (1200 - 1275 CE) the entire area east of Cahokia saw an intensive construction episode. The village area and all of its structures was razed and the "Ramey Plaza" and its associat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collinsville, Illinois

Mississippian Copper Plates
Mississippian copper plates, or plaques, are plain and repousséd plates of beaten copper crafted by peoples of the various regional expressions of the Mississippian culture between 800 and 1600 CE. They have been found as artifacts in archaeological sites in the American Midwest and Southeast. The plates, found as far afield as Florida, Georgia, Illinois, Mississippi, Oklahoma, Tennessee, and Wisconsin, were instrumental in the development of the archaeological concept known as the Southeastern Ceremonial Complex. Some of the more notable examples are representations of raptorial birds and avian-themed dancing warriors. Copper in the Eastern Woodlands Copper trade routes throughout the Eastern Woodlands were established during the Archaic period (3000 - 1000 BCE) and continued into historic times.Brose et al. (1985), Ancient Art of the American Woodlands Indians : 149 Copper was usually imported from the Great Lakes region; however other sources of copper have been found el ...

Fictive Kinship
Fictive kinship is a term used by anthropologists and ethnographers to describe forms of kinship or social ties that are based on neither consanguineal (blood ties) nor affinal ("by marriage") ties. It contrasts with ''true kinship'' ties. To the extent that consanguineal and affinal kinship ties might be considered ''real'' or ''true'' kinship, the term ''fictive kinship'' has in the past been used to refer to those kinship ties that are ''fictional'', in the sense of ''not-real''. Invoking the concept as a cross-culturally valid anthropological category therefore rests on the presumption that the inverse category of "(true) kinship" built around consanguinity and affinity is similarly cross-culturally valid. Use of the term was common until the mid-to-late twentieth century, when anthropology effectively deconstructed and revised many of the concepts and categories around the study of kinship and social ties. In particular, anthropologists established that a consanguinity basi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long-nosed God Maskette
Long-nosed god maskettes are artifacts made from bone, copper and marine shells (Lightning whelk) associated with the Mississippian culture (800 to 1600 CE) and found in archaeological sites in the Midwestern United States and the Southeastern United States. They are small shield-shaped faces with squared-off foreheads, circular eyes, and large noses of various lengths. They are often shown on Southeastern Ceremonial Complex representations of falcon impersonators as ear ornaments. Long and short nosed versions of the masks have been found in ten different states, with the majority found at sites in Illinois. Many archaeologists now associate them with the Ho-Chunk (Winnebago) stories of the mythological being Red Horn. Archaeology The first long nosed god maskette was found next to a skull in a grave in Big Mound in St. Louis in 1870. Since then over twenty of these artifacts have been discovered in an area encompassing at least ten states. They have also been found in Alabama, A ...

Annealing (metallurgy)
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling. In annealing, atoms migrate in the crystal lattice and the number of dislocations decreases, leading to a change in ductility and hardness. As the material cools it recrystallizes. For many alloys, including carbon steel, the crystal grain size and phase composition, which ultimately determine the material properties, are dependent on the heating rate and cooling rate. Hot working or cold working after the annealing process alters the metal structure, so further heat treatments may be used to achieve the properties required. With knowledge of the composition and phase diagram, heat treatment can be used to ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mound 72
Mound 72 is a small ridgetop mound located roughly to the south of Monks Mound at Cahokia Mounds near Collinsville, Illinois. Early in the site's history, the location began as a circle of 48 large wooden posts known as a "woodhenge". The woodhenge was later dismantled and a series of mortuary houses, platform mounds, mass burials and eventually the ridgetop mound erected in its place. The mound was the location of the "beaded burial", an elaborate burial of an elite personage thought to have been one of the rulers of Cahokia, accompanied by the graves of several hundred retainers and sacrificial victims. Mound 72 Woodhenge Early in the history of Cahokia the portion of the site containing Mounds 72 and 96 was the location of a "woodhenge", a ceremonial area with a in diameter circle of 48 upright wooden posts. Archaeologists date the placement of at least one of the posts to approximately 950 CE. Archaeological research has shown that four of the posts were at the cardinal loca ...

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 ...

Spiro Mounds
Spiro Mounds ( 34 LF 40) is an archaeological site located in present-day eastern Oklahoma that remains from an indigenous Indian culture that was part of the major northern Caddoan Mississippian culture. The 80-acre site is located within a floodplain on the southern side of the Arkansas River. The modern town of Spiro developed approximately seven miles to the south. Between the ninth and fifteenth centuries, the local indigenous people created a powerful religious and political center, culturally linked to the Southeastern Ceremonial Complex identified by anthropologists as the Mississippian Ideological Interaction Sphere (MIIS). Spiro was a major western outpost of Mississippian culture, which dominated the Mississippi Valley and its tributaries for centuries. In the 1930s during the Great Depression, treasure hunters bought the rights to tunnel into Craig Mound—the second-largest mound on the site—to mine it for artifacts. Without concern for scientific research, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shell Gorget
Shell gorgets are a Native American art form of polished, carved shell pendants worn around the neck. The gorgets are frequently engraved, and are sometimes highlighted with pigments, or fenestrated (pierced with openings). Shell gorgets were most common in Eastern Woodlands of the United States, during the Hopewell tradition (200 BCE– 500 CE) and Mississippian cultural period (ca. 800–1500 CE); however, tribes from other regions and time periods also carved shell gorgets. The earliest shell gorgets date back to 3000 years BP. They are believed to have been insignia of status or rank,C.
