Megalithic
A megalith is a large Rock (geology), stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. More than 35,000 megalithic structures have been identified across Europe, ranging geographically from Sweden in the north to the Mediterranean Sea in the south. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from the Ancient Greek words "wikt:μέγας, mega" for great and "wikt:λίθος, lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the Chalcolithic, Chalcolithic period and into the Bronze Age. Types and definitions While "megalith" is often used to describe a single piece of stone, it also can be used to denote one or more rocks hewn in definite shapes for special purposes. It has been used to describe structures built by people from many parts of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stone Circles
A stone circle is a ring of megalithic standing stones. Most are found in Northwestern Europe – especially Stone circles in the British Isles and Brittany – and typically date from the Late Neolithic and Early Bronze Age, with most being built between 3300 and 2500 BC. The best known examples include those at the henge monument at Avebury, the Rollright Stones, Castlerigg stone circle, Castlerigg, and elements within the ring of standing stones at Stonehenge. Scattered examples exist from other parts of Europe. Later, during the Iron Age Europe, Iron Age, stone circles were Stone circle (Iron Age), built in southern Scandinavia. The archetypical stone circle is an uncluttered enclosure, large enough to congregate inside, and composed of megalithic stones. Often similar structures are named 'stone circle', but these names are either historic, or incorrect. Examples of commonly misinterpreted stone circles are ring cairns, Tumulus, burial mounds, and kerb cairns. Although it i ...

Stonehenge
Stonehenge is a prehistoric Megalith, megalithic structure on Salisbury Plain in Wiltshire, England, west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around high, wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among contemporary monuments. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within Earthwork (archaeology), earthworks in the middle of the densest complex of Neolithic British Isles, Neolithic and Bronze Age Britain, Bronze Age monuments in England, including several hundred ''tumuli'' (burial mounds). Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Cromlech
A cromlech (sometimes also spelled "cromleh" or "cromlêh"; cf Welsh ''crom'', "bent"; ''llech'', "slate") is a megalithic construction made of large stone blocks. The word applies to two different megalithic forms in English, the first being an altar tomb (frequently called a "dolmen"), as William Borlase first denoted in 1769. A good example is at . The second meaning of the name "cromlech" in English refers to large stone circles such as those found among the Carnac stones in Brittany, France. Unlike in English, the word "cromlech" in many other languages (such as Azerbaijani, Armenian, French, Greek, Indonesian, Italian, Romanian, and Spanish) exclusively denotes a megalithic stone circle, whereas the word "dolmen A dolmen, () or portal tomb, is a type of single-chamber Megalith#Tombs, megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the Late Neolithic period (4000 ..." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menhir
A menhir (; from Brittonic languages: ''maen'' or ''men'', "stone" and ''hir'' or ''hîr'', "long"), standing stone, orthostat, or lith is a large upright stone, emplaced in the ground by humans, typically dating from the European middle Bronze Age. They can be found individually as monoliths, or as part of a group of similar stones. Menhirs' size can vary considerably, but they often taper toward the top. Menhirs are found across Europe, Africa, and Asia, with a concentration in Western Europe, notably in Ireland, Great Britain, and Brittany. Theories concerning their purpose remain speculative, with hypotheses ranging from druidic rituals to territorial markers or elements of an ideological system. Some menhirs feature engravings, including anthropomorphic figures and symbols, and are often associated with ancient religious ceremonies and burial chambers. Etymology The word ''menhir'' was adopted from French by 19th-century archaeologists. The introduction of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spirals
In mathematics, a spiral is a curve which emanates from a point, moving further away as it revolves around the point. It is a subtype of whorled patterns, a broad group that also includes concentric objects. Two-dimensional A two-dimensional, or plane, spiral may be easily described using polar coordinates, where the radius r is a monotonic continuous function of angle \varphi: * r=r(\varphi)\; . The circle would be regarded as a degenerate case (the function not being strictly monotonic, but rather constant). In ''x-y-coordinates'' the curve has the parametric representation: * x=r(\varphi)\cos\varphi \ ,\qquad y=r(\varphi)\sin\varphi\; . Examples Some of the most important sorts of two-dimensional spirals include: * The Archimedean spiral: r=a \varphi * The hyperbolic spiral: r = a/ \varphi * Fermat's spiral: r= a\varphi^ * The lituus: r = a\varphi^ * The logarithmic spiral: r=ae^ * The Cornu spiral or ''clothoid'' * The Fibonacci spiral and golden spiral * ...

Stone Rows
A stone row or stone alignment is a linear arrangement of megalithic standing stones set at intervals along a common axis or series of axes, usually dating from the later Neolithic or Bronze Age.Power (1997), p.23 Rows may be individual or grouped, and three or more aligned stones can constitute a row. Description The term alignment is sometimes taken to imply that the rows were placed purposely in relation to other factors such as other monuments or topographical or astronomical features. Archaeologists treat stone rows as discrete features however and alignment refers to the stones being lined up with one another rather than anything else. Their purpose is thought to be religious or ceremonial perhaps marking a processional route. Another theory is that each generation would erect a new stone to contribute to a sequence that demonstrated a people's continual presence. Stone rows can be few metres or several kilometres in length and made from stones that can be as tall as 2m, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalcolithic
The Chalcolithic ( ) (also called the Copper Age and Eneolithic) was an archaeological period characterized by the increasing use of smelted copper. It followed the Neolithic and preceded the Bronze Age. It occurred at different periods in different areas, but was absent in some parts of the world, such as Russia, where there was no well-defined Copper Age between the Stone and Bronze Ages. Stone tools were still predominantly used during this period. The Chalcolithic covers both the early cold working (hammering) of near pure copper ores, as exhibited by the likes of North American Great Lakes Old Copper complex, from around 6,500 BC, through the later copper smelting cultures. The archaeological site of Belovode, on Rudnik mountain in Serbia, has the world's oldest securely dated evidence of copper smelting at high temperature, from . The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and the late In the Ancient Near East the Copper ...

Tomb
A tomb ( ''tumbos'') or sepulchre () is a repository for the remains of the dead. It is generally any structurally enclosed interment space or burial chamber, of varying sizes. Placing a corpse into a tomb can be called '' immurement'', although this word mainly means entombing people alive, and is a method of final disposition, as an alternative to cremation or burial. Overview The word is used in a broad sense to encompass a number of such types of places of interment or, occasionally, burial, including: * Architectural shrines – in Christianity, an architectural shrine above a saint's first place of burial, as opposed to a similar shrine on which stands a reliquary or feretory into which the saint's remains have been transferred * Burial vault – a stone or brick-lined underground space for multiple burials, originally vaulted, often privately owned for specific family groups; usually beneath a religious building such as a * Church * Cemetery * Churchyard ...
