A wheel is a rotating component that is intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.
Newgrange is a prehistoric monument in County Meath in Ireland, located on a rise overlooking the River Boyne, eight kilometres west of the town of Drogheda. It is an exceptionally grand passage tomb built during the Neolithic Period, around 3200 BC, making it older than Stonehenge and the Egyptian pyramids. Newgrange is the main monument in the Brú na Bóinne complex, a World Heritage Site that also includes the passage tombs of Knowth and Dowth, as well as other henges, burial mounds and standing stones.
A tipi or tepee is a conical lodge tent that is distinguished from other conical tents by the smoke flaps at the top of the structure, and historically made of animal hides or pelts or, in more recent generations, of canvas stretched on a framework of wooden poles. The loanword came into English usage from the Dakota and Lakota languages.
A sun cross, solar cross, or wheel cross is a solar symbol consisting of an equilateral cross inside a circle.
A wigwam, wickiup, wetu (Wampanoag), or wiigiwaam is a semi-permanent domed dwelling formerly used by certain Native American tribes and First Nations people and still used for ceremonial events. The term wickiup is generally used to refer to these kinds of dwellings in the Southwestern United States and Western United States and Northwest Alberta, Canada, while wigwam is usually applied to these structures in the Northeastern United States as well as Ontario and Quebec in central Canada. The names can refer to many distinct types of Indigenous structures regardless of location or cultural group. The wigwam is not to be confused with the Native Plains tipi, which has a different construction, structure, and use.
Petroforms, also known as boulder outlines or boulder mosaics, are human-made shapes and patterns made by lining up large rocks on the open ground, often on quite level areas. Petroforms in North America were originally made by various Native American and First Nation tribes, who used various terms to describe them. Petroforms can also include a rock cairn or inukshuk, an upright monolith slab, a medicine wheel, a fire pit, a desert kite, sculpted boulders, or simply rocks lined up or stacked for various reasons. Old World petroforms include the Carnac stones and many other megalithic monuments.
Writing-on-Stone Provincial Park is located about 100 kilometres (60 mi) southeast of Lethbridge, Alberta, Canada, or 44 kilometres (30 mi) east of the community of Milk River, and straddles the Milk River itself. It is one of the largest areas of protected prairie in the Alberta park system, and serves as both a nature preserve and protection for many First Nations (indigenous) rock carvings and paintings. The park is sacred to the Blackfoot and many other aboriginal tribes.
A recumbent stone circle is a type of stone circle that incorporates a large monolith, known as a recumbent, lying on its side. They are found in only two regions: in Aberdeenshire in the north-east of Scotland and in the far south-west of Ireland in the counties of Cork and Kerry. In Ireland, the circles are now more commonly called Cork–Kerry or axial stone circles. They are believed by some archaeologists such as Aubrey Burl to be associated with rituals in which moonlight played a central role, as they are aligned with the arc of the southern moon. Recent excavations at Tomnaverie stone circle have suggested that no alignment of the circle was intended.
Nabta Playa was once a large endorheic basin in the Nubian Desert, located approximately 800 kilometers south of modern-day Cairo or about 100 kilometers west of Abu Simbel in southern Egypt, 22.51° north, 30.73° east. Today the region is characterized by numerous archaeological sites. The Nabta Playa archaeological site, one of the earliest of the Egyptian Neolithic Period, is dated to circa 7500 BC.
This is a list of Stonehenge replicas and derivatives that seeks to collect all the non-ephemeral examples together. The fame of the prehistoric monument of Stonehenge in England has led to many efforts to recreate it, using a variety of different materials, around the world. Some have been carefully built as astronomically aligned models whilst others have been examples of artistic expression or tourist attractions.
The Callanish Stones are an arrangement of standing stones placed in a cruciform pattern with a central stone circle, located on the Isle of Lewis, Scotland. They were erected in the late Neolithic era, and were a focus for ritual activity during the Bronze Age. They are near the village of Callanish on the west coast of Lewis in the Outer Hebrides, Scotland.
The Medicine Wheel/Medicine Mountain National Historic Landmark is a medicine wheel located in the Bighorn National Forest, in the U.S. state of Wyoming. The Medicine Wheel at Medicine Mountain is a large stone structure made of local white limestone laid upon a bedrock of limestone. It is both a place of sacred ceremony and scientific inquiry. In Native Science these uses are not distinguished as separate as they are in Western science.
Canada's Stonehenge: Astounding Archaeological Discoveries in Canada, England, and Wales is a 2009 self-published book by retired chemistry professor Gordon Freeman, in which the author claims that the Majorville Cairn and Medicine Wheel site, located south of Bassano, Alberta is actually a precise 5,000-year-old calendar. He also discusses Stonehenge, which he believes was also a calendar. Gordon Freeman has no training as an archaeologist, and this work was performed outside of his professional scope of practice as a chemist.
The following outline is provided as an overview of and topical guide to the prehistoric people of Colorado, which covers the period of when Native Americans lived in Colorado prior to contact with the Domínguez–Escalante expedition in 1776. People's lifestyles included nomadic hunter-gathering, semi-permanent village dwelling, and residing in pueblos.
Tipi rings are circular patterns of stones left from an encampment of Post-Archaic, protohistoric and historic Native Americans. They are found primarily throughout the Plains of the United States and Canada, and also in the foothills and parks of the Rocky Mountains.
The Carisbrook stone arrangement is a well-preserved Aboriginal stone arrangement in Victoria, Australia. It measures 60 by 5 metres and is one of only four stone arrangements in the state and the only one of a boomerang design. It is located about 5 km south-east of the town of Carisbrook, on the banks of Tullaroop Creek.
The Majorville Cairn and Medicine Wheel is an archaeological site of the Blackfoot Nation located south of Bassano, Alberta. The medicine wheel has been dated to 3200 BCE by careful stratification of known artifact types.
An axial stone circle is a megalithic ring of stones of a particular design found in County Cork and County Kerry in southwest Ireland. Archaeologists have found it convenient to consider the axial five-stone circle and axial multiple-stone circle separately. The circle has an approximate axis of symmetry aligned in a generally northeast–southwest direction. The stone at the southwest side of the circle, rather than being an upright orthostat like all the rest, is a slab lying horizontally with its long thin edge along the circumference of the ring. Because it marks the axis of the circle it is called the axial stone.
Tomnaverie stone circle is a recumbent stone circle set on the top of a small hill in lowland northeast Scotland. Construction started from about 2500 BC, in the Bronze Age, to produce a monument of thirteen granite stones including a massive 6.5-ton recumbent stone lying on its side along the southwest of the circle's perimeter. Within the 17-metre (56 ft) circle are kerb stones encircling a low 15-metre (49 ft) ring cairn but the cairn itself no longer exists.
