Petroglyph
–
Petroglyphs are images created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use such as carving, engraving. Petroglyphs are found world-wide, and are associated with prehistoric peoples. The word comes from the Greek word petro-, theme of the word meaning stone, and glyphein meaning to carve. The term petroglyph should not be confused with petrograph, which is an image drawn or painted on a rock face, both types of image belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by large rocks. Inukshuks are also unique, and found only in the Arctic and they are a category of rock art, and sometimes found in conjunction with rock-cut architecture. However, they tend to be omitted in most works on rock art, a few such works exploit the natural contours of the rock and use them to define an image, but they do not amount to man-made reliefs. Rock reliefs have been made in many cultures, and were important in the art of the Ancient Near East. Rock reliefs are generally large, as they need to be to make an impact in the open air. Most have figures that are over life-size, and in many the figures are multiples of life-size, the vertical relief is most common, but reliefs on essentially horizontal surfaces are also found. The term typically excludes relief carvings inside caves, whether natural or themselves man-made, natural rock formations made into statues or other sculpture in the round, most famously at the Great Sphinx of Giza, are also usually excluded. Reliefs on large boulders left in their location, like the Hittite İmamkullu relief, are likely to be included. Some petroglyphs are dated to approximately the Neolithic and late Upper Paleolithic boundary, about 10,000 to 12,000 years ago, if not earlier. Sites in Australia have petroglyphs that are estimated to be as much as 27,000 years old, around 7,000 to 9,000 years ago, other precursors of writing systems, such as pictographs and ideograms, began to appear. Petroglyphs were still common though, and some cultures continued using them much longer, petroglyphs have been found in all parts of the globe except Antarctica with highest concentrations in parts of Africa, Scandinavia, Siberia, southwestern North America and Australia. There are many theories to explain their purpose, depending on their location, age, some petroglyphs are thought to be astronomical markers, maps, and other forms of symbolic communication, including a form of pre-writing. Petroglyph maps may show trails, symbols communicating time and distances traveled, as well as the terrain in the form of rivers, landforms

Sculpture
–
Sculpture is the branch of the visual arts that operates in three dimensions. It is one of the plastic arts, a wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or molded, or cast. However, most ancient sculpture was painted, and this has been lost. Those cultures whose sculptures have survived in quantities include the cultures of the ancient Mediterranean, India and China, the Western tradition of sculpture began in ancient Greece, and Greece is widely seen as producing great masterpieces in the classical period. During the Middle Ages, Gothic sculpture represented the agonies and passions of the Christian faith, the revival of classical models in the Renaissance produced famous sculptures such as Michelangelos David. Relief is often classified by the degree of projection from the wall into low or bas-relief, high relief, sunk-relief is a technique restricted to ancient Egypt. Relief sculpture may also decorate steles, upright slabs, usually of stone, techniques such as casting, stamping and moulding use an intermediate matrix containing the design to produce the work, many of these allow the production of several copies. The term sculpture is used mainly to describe large works. The very large or colossal statue has had an enduring appeal since antiquity, another grand form of portrait sculpture is the equestrian statue of a rider on horse, which has become rare in recent decades. The smallest forms of life-size portrait sculpture are the head, showing just that, or the bust, small forms of sculpture include the figurine, normally a statue that is no more than 18 inches tall, and for reliefs the plaquette, medal or coin. Sculpture is an important form of public art, a collection of sculpture in a garden setting can be called a sculpture garden. One of the most common purposes of sculpture is in form of association with religion. Cult images are common in cultures, though they are often not the colossal statues of deities which characterized ancient Greek art. The actual cult images in the innermost sanctuaries of Egyptian temples, of which none have survived, were rather small. The same is true in Hinduism, where the very simple. Some undoubtedly advanced cultures, such as the Indus Valley civilization, appear to have had no monumental sculpture at all, though producing very sophisticated figurines, the Mississippian culture seems to have been progressing towards its use, with small stone figures, when it collapsed. Other cultures, such as ancient Egypt and the Easter Island culture, from the 20th century the relatively restricted range of subjects found in large sculpture expanded greatly, with abstract subjects and the use or representation of any type of subject now common. Today much sculpture is made for intermittent display in galleries and museums, small sculpted fittings for furniture and other objects go well back into antiquity, as in the Nimrud ivories, Begram ivories and finds from the tomb of Tutankhamun

Stone sculpture
–
Stone sculpture is the result of forming 3-dimensional visually interesting objects from stone. It is an ancient activity where pieces of natural stone are shaped by the controlled removal of stone. Petroglyphs are perhaps the earliest form, images created by removing part of a surface which remains in situ, by incising, pecking, carving. Monumental sculpture covers large works, and architectural sculpture, which is attached to buildings. Hardstone carving is the carving for artistic purposes of semi-precious stones such as jade, agate, onyx, rock crystal, sard or carnelian, alabaster or mineral gypsum is a soft mineral that is easy to carve for smaller works and still relatively durable. Engraved gems are small carved gems, including cameos, originally used as seal rings, carving stone into sculpture is an activity older than civilization itself, beginning perhaps with incised images on cave walls. Prehistoric sculptures were usually human forms, such as the Venus of Willendorf, later cultures devised animal, human-animal and abstract forms in stone. The earliest cultures used abrasive techniques, and modern technology employs pneumatic hammers, but for most of human history, sculptors used hammer and chisel as the basic tools for carving stone. In the direct method of carving, the work usually begins with the selection of a stone for carving. The artist using the method may use sketches but eschews the use of a physical model. The fully dimensional form or figure is created for the first time in the stone itself, as the artist removes material, sketches on the block of stone, and develops the work along the way. On the other hand, is the method, when the sculptor begins with a clearly defined model to be copied in stone. The models, usually made of plaster or modeling clay, may be fully the size of the intended sculpture, once the model is complete, a suitable stone must be found to fit the intended design. The model is copied in stone by measuring with calipers or a pointing machine. This method is used when the carving is done by other sculptors. Some artists use the stone itself as inspiration, the Renaissance artist Michelangelo claimed that his job was to free the human form hidden inside the block. When he or she is ready to carve, the carver usually begins by knocking off, or pitching, large portions of unwanted stone. For this task he may select a point chisel, which is a long, hefty piece of steel with a point at one end, a pitching tool may also be used at this early stage, which is a wedge-shaped chisel with a broad, flat edge

Cathedral of Saint John the Divine
–
The Cathedral of St. John the Divine, officially the Cathedral Church of Saint John, The Great Divine in the City and Diocese of New York, is the cathedral of the Episcopal Diocese of New York. It is located in New York City on Amsterdam Avenue between West 110th Street and 113th Street in Manhattans Morningside Heights neighborhood, designed in 1888 and begun in 1892, the cathedral has undergone radical stylistic changes and the interruption of the two World Wars. Originally designed in the Byzantine Revival-Romanesque Revival styles, the plan was changed after 1909 to a Gothic Revival design, after a large fire on December 18,2001, it was closed for repairs and reopened in November 2008. It remains unfinished, with construction and restoration a continuing process, as a result, it is often nicknamed St. John the Unfinished. There is a dispute whether this cathedral or Liverpool Cathedral is the worlds largest Anglican cathedral. It is also the fourth largest Christian church in the world, the interior covers 121,000 sq ft, spanning a length of 601 ft and height 232 ft. The interior height of the nave is 124 feet, the cathedral houses one of the nations premier textile conservation laboratories to conserve the cathedrals textiles, including the Barberini tapestries to cartoons by Raphael. The laboratory also conserves tapestries, needlepoint, upholstery, costumes, in 1887 Bishop Henry Codman Potter of the Episcopal Diocese of New York called for a cathedral to rival the Catholic St. Patricks Cathedral in Manhattan. An 11. 5-acre property, on which the Leake and Watts Orphan Asylum had stood, was purchased by deed for the cathedral in 1891. After an open competition, a design by the New York firm of George Lewis Heins, the foundations were completed at enormous expense, largely because bedrock was not struck until the excavation had reached 72 feet. The walls were built around eight massive 130-ton, 50-foot granite columns, each turned as one piece, sourced from Vinalhaven, Maine and said to be the largest in the world. The columns, which were transported to New York on a specially constructed barge towed by the steam tug Clara Clarita. The first services were held in the crypt, under the crossing in 1899, the Ardolino brothers from Torre di Nocelli, Italy, did much of the stone carving work on the statues designed by the English sculptor John Angel. After the large dome made of Guastavino tile was completed in 1909. Grant LaFarge, and hire the noted Gothic Revival architect Ralph Adams Cram to design the nave, in 1911, the choir and the crossing were opened, and the foundation for Crams nave began to be excavated in 1916. J. Sanford Saltus, namesake of the American Numismatic Societys Saltus Award, Manning with a life-size statue of Joan of Arc for the Cathedrals French Chapel, which was dedicated in January 1923. The first stone of the nave was laid, and the west front was undertaken in 1925, Bishop Manning had announced a $10 million capital campaign to raise money for this project at a major press conference, the New York campaign committee was headed by Franklin D. Roosevelt. Work at the church went on during the Great Depression as a result of monies raised in this campaign, the Cathedral was opened end-to-end for the first time on November 30,1941, a week before the bombing of Pearl Harbor

Al-Khazneh
–
Al-Khazneh is one of the most elaborate temples in the ancient Arab Nabatean Kingdom city of Petra. As with most of the buildings in this ancient town, including the Monastery. The treasury was built by the Arab Nabateans, coinciding with the time of the Hellenistic and Roman Empires, the temple is a popular tourist attraction in both Jordan and the region. Al-Khazneh was originally built as a mausoleum and crypt at the beginning of the 1st century AD during the reign of Aretas IV Philopatris and its Arabic name Treasury derives from one legend that bandits or pirates hid their loot in a stone urn high on the second level. Significant damage from bullets can be seen on the urn, another legend is that it functioned as a treasury of the Egyptian Pharaoh at the time of Moses. Many of the architectural details have eroded away during the two thousand years since it was carved and sculpted from the cliff. The sculptures are thought to be those of mythological figures associated with the afterlife. On top are figures of four eagles that would carry away the souls, the figures on the upper level are dancing Amazons with double-axes. The entrance is flanked by statues of the twins Castor and Pollux who lived partly on Olympus, in 1812, the city of Petra and Al-Khazneh was rediscovered by Swiss explorer Johann Ludwig Burckhardt. As the west continued to colonize the Middle East, tourism became more common, and by the 1920s, while Petra was not as popular as larger, more central cities like Cairo, tourism started to change the economy and social structure of the Bedouin people who lived nearby. Tourism is now the source of income in Jordan. Hotels, souvenir shops, restaurants and horse rental services are all found within a few mile radius of Petra itself, while the economic effects have been largely positive, the site itself faces threat from the increased tourism. Humidity from large crowds of people visiting the site can cause damage to the dry sandstone, white spots have appeared on walls and columns from stearic acid deposition due to hands resting against the walls. The Khazneh surface itself has receded by 40mm in less than ten years from touching, leaning, the interior scenes of the temple were filmed at Elstree Studios in England. Ancient Megastructures, Petra, a series from National Geographic Channel, is dedicated to the Khazneh, explaining how it was created through human resourcefulness.

Petra
–
Petra, originally known to the Nabataeans as Raqmu, is a historical and archaeological city in southern Jordan. The city is famous for its architecture and water conduit system. Another name for Petra is the Rose City due to the color of the out of which it is carved. Established possibly as early as 312 BC as the city of the Arab Nabataeans, it is a symbol of Jordan. The Nabataeans were nomadic Arabs who took advantage of Petras proximity to trade routes to establish it as a major trading hub. The Nabataeans are also known for their ability in constructing efficient water-collecting methods in the barren deserts. Petra lies on the slope of Jebel al-Madhbah in a basin among the mountains form the eastern flank of Arabah. It has been a UNESCO World Heritage Site since 1985, the site remained unknown to the western world until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt. It was described as a rose-red city half as old as time in a Newdigate Prize-winning poem by John William Burgon, UNESCO has described it as one of the most precious cultural properties of mans cultural heritage. Petra was named amongst the New7Wonders of the World in 2007 and was chosen by the Smithsonian Magazine as one of the 28 Places to See Before You Die. Pliny the Elder and other writers identify Petra as the capital of the Nabataeans, excavations have demonstrated that it was the ability of the Nabataeans to control the water supply that led to the rise of the desert city, creating an artificial oasis. The area is visited by flash floods, and archaeological evidence demonstrates the Nabataeans controlled these floods by the use of dams, cisterns and these innovations stored water for prolonged periods of drought and enabled the city to prosper from its sale. Another approach was possibly from the plateau to the north. Today, most modern visitors approach the site from the east, at the end of the narrow gorge stands Petras most elaborate ruin, Al Khazneh, hewn into the sandstone cliff. A little farther from the Treasury, at the foot of the mountain called en-Nejr, is a massive theatre, at the point where the valley opens out into the plain, the site of the city is revealed with striking effect. The amphitheatre has been cut into the hillside and into several of the tombs during its construction, rectangular gaps in the seating are still visible. Almost enclosing it on three sides are rose-colored mountain walls, divided into groups by deep fissures and lined with knobs cut from the rock in the form of towers. By 2010 BC, some of the earliest recorded farmers had settled in Beidha, Petra is listed in Egyptian campaign accounts and the Amarna letters as Pel, Sela or Seir

Goshavank
–
Goshavank is a 12th- or 13th-century Armenian monastery located in the village of Gosh in the Tavush Province of Armenia. Today the monastery is not a religious complex, although it remains a popular tourist destination and has recently undergone some light restoration. These restorations are being financed by an Islamic individual from the United Arab Emirates for reasons not fully understood, the impressive monastery which has remained in relatively good condition also houses one of the worlds finest examples of a khachkar. Goshavank was erected in the place of a monastery once known as Nor Getik. Mkhitar Gosh, a statesman, scientist and author of fables and parables as well as the first criminal code. At Goshavank, Mkhitar Gosh founded a school, one of its alumni, an Armenian scientist by the name of Kirakos Gandzaketsi wrote The History of Armenia. The architect Mkhitar the Carpenter and his disciple Hovhannes also took a part in the building of the monastery. The complex was later renamed Goshavank and the village named Gosh in his honor, Goshavank does not have outer walls, and is surrounded by village homes. All of the buildings are attached to each other except for S. Hripsime Chapel, numerous religious and monumental civil buildings show that in the twelfth to thirteenth centuries the monastery was full of life. The churches are decorated in accordance with the traditions of the time, as a rule, the door portals and windows are framed in rectangular or arched platbands some of which are profiled. The façade niches have multifoil or scalloped tops like those of the niches of the church at Geghard. The unusual and artistically framed sun dial on the southern façade is a decorative element. The main churches belong to the types widespread in the tenth to the thirteenth centuries, St. Gregory Church is found between the three chapels. The small interior has intricate carvings over most of the surface and it is a small vaulted structure. The bottom of the apse is trimmed by a graceful arcature topped with a band which is ornamented with an intricate geometrical pattern and garlands of alternating trefoils. The exterior decoration of the church is also rich, the graceful arcature with ornamented spandrels, engirdling the edifice, is topped with half-arches on the corners. This creates not only a decoration of the facets of the edifice. The decoration of the facades, especially of the western one, is divided in height into separate parts to produce an impression of a substantial size

Rock (geology)
–
Rock or stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a rock, is a combination of the minerals quartz, feldspar. The Earths outer solid layer, the lithosphere, is made of rock, rock has been used by mankind throughout history. The minerals and metals found in rocks have been essential to human civilization, three major groups of rocks are defined, igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is a component of geology. At a granular level, rocks are composed of grains of minerals, the aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed, many rocks contain silica, a compound of silicon and oxygen that forms 74. 3% of the Earths crust. This material forms crystals with other compounds in the rock, the proportion of silica in rocks and minerals is a major factor in determining their name and properties. Rocks are geologically classified according to such as mineral and chemical composition, permeability, the texture of the constituent particles. These physical properties are the end result of the processes that formed the rocks, over the course of time, rocks can transform from one type into another, as described by the geological model called the rock cycle. These events produce three general classes of rock, igneous, sedimentary, and metamorphic, the three classes of rocks are subdivided into many groups. However, there are no hard and fast boundaries between allied rocks, hence the definitions adopted in establishing rock nomenclature merely correspond to more or less arbitrary selected points in a continuously graduated series. Igneous rock forms through the cooling and solidification of magma or lava and this magma can be derived from partial melts of pre-existing rocks in either a planets mantle or crust. Typically, the melting of rocks is caused by one or more of three processes, an increase in temperature, a decrease in pressure, or a change in composition, igneous rocks are divided into two main categories, plutonic rock and volcanic. Plutonic or intrusive rocks result when magma cools and crystallizes slowly within the Earths crust, a common example of this type is granite. Volcanic or extrusive rocks result from magma reaching the surface either as lava or fragmental ejecta, the chemical abundance and the rate of cooling of magma typically forms a sequence known as Bowens reaction series. Most major igneous rocks are found along this scale, about 64. 7% of the Earths crust by volume consists of igneous rocks, making it the most plentiful category. Of these, 66% are basalts and gabbros, 16% are granite, only 0. 6% are syenites and 0. 3% peridotites and dunites

Prehistory
–
Prehistory means literally before history, from the Latin word for before, præ, and Greek ιστορία. Neighbouring civilisations were the first to follow, most other civilisations reached the end of prehistory during the Iron Age. The period when a culture is written about by others, but has not developed its own writing is known as the protohistory of the culture. By definition, there are no records from human prehistory. Clear techniques for dating were not well-developed until the 19th century and this article is concerned with human prehistory as defined here above. There are separate articles for the history of the Earth. However, for the race as a whole, prehistory ends when recorded history begins with the accounts of the ancient world around the 4th millennium BC. For example, in Egypt it is accepted that prehistory ended around 3200 BC, whereas in New Guinea the end of the prehistoric era is set much more recently. The three-age system is the periodization of prehistory into three consecutive time periods, named for their respective predominant tool-making technologies, Stone Age Bronze Age Iron Age. The notion of prehistory began to surface during the Enlightenment in the work of antiquarians who used the word primitive to describe societies that existed before written records, the first use of the word prehistory in English, however, occurred in the Foreign Quarterly Review in 1836. The main source for prehistory is archaeology, but some scholars are beginning to more use of evidence from the natural and social sciences. This view has been articulated by advocates of deep history, human population geneticists and historical linguists are also providing valuable insight for these questions. Human prehistory differs from history not only in terms of its chronology, restricted to material processes, remains and artifacts rather than written records, prehistory is anonymous. Because of this, reference terms that use, such as Neanderthal or Iron Age are modern labels with definitions sometimes subject to debate. Palaeolithic means Old Stone Age, and begins with the first use of stone tools, the Paleolithic is the earliest period of the Stone Age. The early part of the Palaeolithic is called the Lower Palaeolithic, evidence of control of fire by early humans during the Lower Palaeolithic Era is uncertain and has at best limited scholarly support. The most widely accepted claim is that H. erectus or H. ergaster made fires between 790,000 and 690,000 BP in a site at Bnot Yaakov Bridge, Israel. The use of fire enabled early humans to cook food, provide warmth, Early Homo sapiens originated some 200,000 years ago, ushering in the Middle Palaeolithic
10.
Paleolithic
–
It extends from the earliest known use of stone tools, probably by Homo habilis initially,2.6 million years ago, to the end of the Pleistocene around 10,000 BP. The Paleolithic era is followed by the Mesolithic, the date of the Paleolithic–Mesolithic boundary may vary by locality as much as several thousand years. During the Paleolithic period, humans grouped together in small societies such as bands, the Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers, however, due to their nature, surviving artifacts of the Paleolithic era are known as paleoliths. About 50,000 years ago, there was a increase in the diversity of artifacts. For the first time in Africa, bone artifacts and the first art appear in the archaeological record, the first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa. The new technology generated an explosion of modern humans which is believed to have led to the extinction of the Neanderthals. Humankind gradually evolved from members of the genus Homo—such as Homo habilis. The climate during the Paleolithic consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures, by c. 50,000 – c. 40,000 BP, the first humans set foot in Australia. By c. 45,000 BP, humans lived at 61°N latitude in Europe, by c. 30,000 BP, Japan was reached, and by c. 27,000 BP humans were present in Siberia, above the Arctic Circle. At the end of the Upper Paleolithic, a group of humans crossed Beringia, the term Paleolithic was coined by archaeologist John Lubbock in 1865. It derives from Greek, παλαιός, palaios, old, and λίθος, lithos, stone, human evolution is the part of biological evolution concerning the emergence of anatomically modern humans as a distinct species. The Paleolithic Period coincides almost exactly with the Pleistocene epoch of geologic time and this epoch experienced important geographic and climatic changes that affected human societies. During the preceding Pliocene, continents had continued to drift from possibly as far as 250 km from their present locations to positions only 70 km from their current location. South America became linked to North America through the Isthmus of Panama, most of Central America formed during the Pliocene to connect the continents of North and South America, allowing fauna from these continents to leave their native habitats and colonize new areas. Africas collision with Asia created the Mediterranean Sea, cutting off the remnants of the Tethys Ocean, climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. The formation of an Arctic ice cap around 3 million years ago is signaled by a shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic. Mid-latitude glaciation probably began before the end of the epoch, the global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas

Stone tool
–
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric, archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a research field in order to further the understanding and cultural implications of stone tool use. Stone has been used to make a variety of different tools throughout history, including arrow heads, spearpoints. Stone tools may be made of ground stone or chipped stone. Chipped stone tools are made from materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt. One simple form of reduction is to strike stone flakes from a nucleus of material using a hammerstone or similar hard hammer fabricator, if the goal of the reduction strategy is to produce flakes, the remnant lithic core may be discarded once it has become too small to use. In some strategies, however, a flintknapper reduces the core to a rough unifacial or bifacial preform, more complex forms of reduction include the production of highly standardized blades, which can then be fashioned into a variety of tools such as scrapers, knives, sickles and microliths. Archaeologists classify stone tools into industries that share distinctive technological or morphological characteristics and he assigned to them relative dates, Modes 1 and 2 to the Lower Palaeolithic,3 to the Middle Palaeolithic,4 to the Advanced and 5 to the Mesolithic. They were not to be conceived, however, as either universal—that is, they did not account for all lithic technology, Mode 1, for example, was in use in Europe long after it had been replaced by Mode 2 in Africa. Clarkes scheme was adopted enthusiastically by the archaeological community, one of its advantages was the simplicity of terminology, for example, the Mode 1 / Mode 2 Transition. The transitions are currently of greatest interest, Kenya Stone tools found from 2011 to 2014 at Lake Turkana in Kenya, are dated to be 3.3 million years old, and predate the genus Homo by half million years. The oldest known Homo fossil is 2.8 million years old compared to the 3.3 million year old stone tools. Dating of the tools was by dating volcanic ash layers in which the tools were found, Oldowan tools were characterised by their simple construction, predominantly using core forms. The blunt end is the surface, the sharp, the distal. Grasping the proximal surface, the hominid brought the surface down hard on an object he wished to detach or shatter. The earliest known Oldowan tools yet found date from 2.6 million years ago, during the Lower Palaeolithic period, and have been uncovered at Gona in Ethiopia. Homo habilis was the hominin who used the tools for most of the Oldowan in Africa, eventually, more complex, Mode 2 tools began to be developed through the Acheulean Industry, named after the site of Saint-Acheul in France

Knapping
–
The original Germanic term knopp meant strike, shape, or work, so it could theoretically have referred equally well to making a statue or dice. Modern usage is specific, referring almost exclusively to the hand-tool pressure-flaking process pictured. Flintknapping or knapping is done in a variety of ways depending on the purpose of the final product, for stone tools and flintlock strikers, chert is worked using a fabricator such as a hammerstone to remove lithic flakes from a nucleus or core of tool stone. Stone tools can then be refined using wood, bone. For building work a hammer or pick is used to split chert nodules supported on the lap, often the chert nodule will be split in half to create two cherts with a flat circular face for use in walls constructed of lime. More sophisticated knapping is employed to produce almost perfect cubes which are used as bricks, there are many different methods of shaping stone into useful tools. Early knappers could have used hammers made of wood or antler to shape stone tools. The factors that contribute to the results are varied, but the EPA indeed influences many attributes, such as length, thickness. Hard hammer techniques are used to remove large flakes of stone, early knappers and hobbyists replicating their methods often use cobbles of very hard stone, such as quartzite. This technique can be used by flintknappers to remove broad flakes that can be made into smaller tools and this method of manufacture is believed to have been used to make some of the earliest stone tools ever found, some of which date from over 2 million years ago. Soft hammer techniques are more precise than hard hammer methods of shaping stone, soft hammer techniques allow a knapper to shape a stone into many different kinds of cutting, scraping, and projectile tools. These soft hammer techniques also produce longer, thinner flakes, potentially allowing for material conservation or a lighter lithic tool kit to be carried by mobile societies, pressure flaking involves removing narrow flakes along the edge of a stone tool. This technique is used to do detailed thinning and shaping of a stone tool. Pressure flaking involves putting an amount of force across a region on the edge of the tool. The major advantage of using soft metals rather than wood or bone is that the metal punches wear down less and are likely to break under pressure. Archaeologists usually undertake the task so that they can understand how prehistoric stone tools were made. Knapping is often learned by outdoorsmen, such as British bushcraft exponent Ray Mears, knapping gun flints, used by flintlock firearms was formerly a major industry in flint bearing locations, such as Brandon in Suffolk, England and the small towns of Meusnes and Couffy in France. Meusnes has a museum dedicated to the industry
