Alignment (archaeology)
An alignment in archaeology is a co-linear arrangement of features or structures with external landmarks, in archaeoastronomy the term may refer to an alignment with an astronomically significant point or axis. "Alignment" may also refer to circumstantial or secondary type of evidence used to infer archaeological association of archeological features, such as postholes, by virtue of their physical relationships rather than stratigraphic ones. Types Large scale alignments The alignment of features on a site within or across several archaeological phases many times is an indication of a larger topology to the formation of features relating to activity in the archaeological record. Structures buildings and liner features such as ditches can all have common alignments that relate to a feature that is not exposed during excavation or is off-site. An example would be that a road has biased the alignment of features some way back from the actual road side. Another example will be co ...

Ley Line
Ley lines () are straight alignments drawn between various historic structures and prominent landmarks. The idea was developed in early 20th-century Europe, with ley line believers arguing that these alignments were recognised by ancient societies that deliberately erected structures along them. Since the 1960s, members of the Earth Mysteries movement and other esoteric traditions have commonly believed that such ley lines demarcate " earth energies" and serve as guides for alien spacecraft. Archaeologists and scientists regard ley lines as an example of pseudoarchaeology and pseudoscience. The idea of "leys" as straight tracks across the landscape was put forward by the English antiquarian Alfred Watkins in the 1920s, particularly in his book ''The Old Straight Track''. He argued that straight lines could be drawn between various historic structures and that these represented trade routes created by ancient British societies. Although he gained a small following, Watkins' idea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stonehenge
Stonehenge is a prehistoric monument 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. 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. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred ''tumuli'' (burial mounds). Archaeologists believe that Stonehenge was constructed from around 3000 BC to 2000 BC. The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. Radiocarbon dating suggests that the first bluestones were raised between 2400 and 2200 BC, althou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giza Necropolis
The Giza pyramid complex ( ar, مجمع أهرامات الجيزة), also called the Giza necropolis, is the site on the Giza Plateau in Greater Cairo, Egypt that includes the Great Pyramid of Giza, the Pyramid of Khafre, and the Pyramid of Menkaure, along with their associated pyramid complexes and the Great Sphinx of Giza. All were built during the Fourth Dynasty of the Old Kingdom of Ancient Egypt, between 2600 and 2500 BC. The site also includes several cemeteries and the remains of a workers' village. The site is at the edges of the Western Desert, approximately west of the Nile River in the city of Giza, and about southwest of the city centre of Cairo. Along with nearby Memphis, the site was inscribed on the UNESCO World Heritage List in 1979. The Great Pyramid and the Pyramid of Khafre are the largest pyramids built in ancient Egypt, and they have historically been common as emblems of Ancient Egypt in the Western imagination. They were popularised in Hellenistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burial
Burial, also known as interment or inhumation, is a method of final disposition whereby a dead body is placed into the ground, sometimes with objects. This is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. A funeral is a ceremony that accompanies the final disposition. Humans have been burying their dead since shortly after the origin of the species. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life. Methods of burial may be heavily ritualized and can include natural burial (sometimes called "green burial"); embalming or mummification; and the use of containers for the dead, such as shrouds, coffins, grave liners, and ...

Archaeomagnetic Dating
Archaeomagnetic dating is the study and interpretation of the signatures of the Earth's magnetic field at past times recorded in archaeological materials. These paleomagnetism, paleomagnetic signatures are fixed when ferromagnetic materials such as magnetite cool below the Curie point, freezing the magnetic moment of the material in the direction of the local magnetic field at that time. The direction and magnitude of the magnetic field of the Earth at a particular location Geomagnetic reversal, varies with time, and can be used to constrain the age of materials. In conjunction with techniques such as radiometric dating, the technique can be used to construct and calibrate the geomagnetic polarity time scale. This is one of the Dating methodology (archaeology), dating methodologies used for sites within the last 10,000 years. The method was conceived by E. Thellier in the 1930s and the increased sensitivity of SQUID magnetometers has greatly promoted its use. Instances of use The E ...

Paleomagnetism
Paleomagnetism (or palaeomagnetismsee ), is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called ''paleomagnetists.'' Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic field at the time they formed. This record provides information on the past behavior of the geomagnetic field and the past location of tectonic plates. The record of geomagnetic reversals preserved in volcanic and sedimentary rock sequences (magnetostratigraphy) provides a time-scale that is used as a geochronologic tool. Evidence from paleomagnetism led to the revival of the continental drift hypothesis and its transformation into the modern theory of plate tectonics. Apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomaly, magnetic anomalies did the same for seafloor spreading. Paleomagnetic data continues t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Row
A stone row or stone alignment is a linear arrangement of upright, parallel 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 stones aligned can constitute a stone row. Description Stone rows can be few metres or several kilometres in length and made from stones that can be as tall as 2m, although 1m high stones are more common. The terminals of many rows have the largest stones and other megalithic features are sometimes sited at the ends, especially burial cairns. The stones are placed at intervals and may vary in height along the sequence, to provide a graduated appearance, though it is not known whether this was done deliberately. Stone rows were erected by the later Neolithic and Bronze Age peoples in the British Isles, parts of Scandinavia and northern France. The most famous example is the Carnac stones, a comp ...

Surveying
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designed positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, LiDAR sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface locators, d ...

Alfred Watkins
Alfred Watkins (27 January 1855 – 15 April 1935) was an English author, self-taught amateur archaeologist, antiquarian and businessman who, while standing on a hillside in Herefordshire, England, in 1921 experienced a revelation. He noticed on the British landscape an apparent arrangement of straight lines positioned along ancient features. For these he subsequently coined the term "ley", now usually referred to as ley line, because the line passed through places whose names contained the syllable "ley". Life Watkins was born in Hereford to an affluent family which had moved to the town in 1820 to establish several businesses including a flour-mill, a hotel and brewery. Watkins travelled across Herefordshire as an 'out-rider' representing the family businesses and so got to know the area intimately. Watkins was also a respected photographer. He made some cameras himself and manufactured an exposure meter called the Watkins Bee Meter due to its small size and efficiency ...

Statistical Significance
In statistical hypothesis testing, a result has statistical significance when it is very unlikely to have occurred given the null hypothesis (simply by chance alone). More precisely, a study's defined significance level, denoted by \alpha, is the probability of the study rejecting the null hypothesis, given that the null hypothesis is true; and the ''p''-value of a result, ''p'', is the probability of obtaining a result at least as extreme, given that the null hypothesis is true. The result is statistically significant, by the standards of the study, when p \le \alpha. The significance level for a study is chosen before data collection, and is typically set to 5% or much lower—depending on the field of study. In any experiment or observation that involves drawing a sample from a population, there is always the possibility that an observed effect would have occurred due to sampling error alone. But if the ''p''-value of an observed effect is less than (or equal to) the significanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeology
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
