Megalith
A megalith is a large 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 " mega" for great and " lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the 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 world living in many different periods. The most widely known ...

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] |
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] |

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 ...

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] |
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] |
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 * ...

Monolith
A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano. In architecture, the term has considerable overlap with megalith, which is normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces. The word derives, via the Latin , from the Ancient Greek word (), from () meaning "one" or "single" and () meaning "stone". Geological monoliths Large, well-known monoliths include: Africa * Aso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclopean Walls
Cyclopean masonry is a type of stonework found in Mycenaean architecture, built with massive limestone boulders, roughly fitted together with minimal clearance between adjacent stones and with clay mortar or no use of mortar. The boulders typically seem unworked, but some may have been worked roughly with a hammer and the gaps between boulders filled in with smaller chunks of limestone. The most famous examples of Cyclopean masonry are found in the walls of Mycenae and Tiryns, and the style is characteristic of Mycenaean fortifications. Similar styles of stonework are found in other cultures and the term has come to be used to describe typical stonework of this sort. The term comes from the belief of classical Greeks that only the mythical Cyclopes had the strength to move the enormous boulders that made up the walls of Mycenae and Tiryns. Pliny's ''Natural History'' reported the tradition, attributed to Aristotle, that the Cyclopes were the inventors of masonry towers, givin ...
