101-665: In 1983, archaeologists uncovered the Chieftain House at Borg ( På Borg på Vestvågøya i Lofoten ), a large Viking Age building believed to have been already established around the year 500 AD. A joint Scandinavian research project was conducted at Borg from 1986 until 1989. Excavations revealed the largest building ever to be found from the Viking period in Norway. The foundation of the Chieftain House at Borg measured 83 metres (272 ft) long and 9.5 metres (31 ft) wide, and

202-464: A basic level of analysis, artifacts found are cleaned, catalogued and compared to published collections. This comparison process often involves classifying them typologically and identifying other sites with similar artifact assemblages. However, a much more comprehensive range of analytical techniques are available through archaeological science , meaning that artifacts can be dated and their compositions examined. Bones, plants, and pollen collected from

303-563: A big impact throughout Europe. However, prior to the development of modern techniques, excavations tended to be haphazard; the importance of concepts such as stratification and context were overlooked. In the mid-18th century, the German Johann Joachim Winckelmann lived in Rome and devoted himself to the study of Roman antiquities, gradually acquiring an unrivalled knowledge of ancient art. Then, he visited

404-524: A blacksmith's forge, two ships (replicas of the Gokstad ship, one in full scale size) and their boathouses, and various reenactments intended to immerse the visitor in life at the time of the Vikings. The main building was designed by Norwegian architect, Gisle Jakhelln. In September 2006, a planned enlargement of Lofotr, the building of a large amphitheater into the ground between the reception building and

505-401: A clear objective as to what the archaeologists are looking to achieve must be agreed upon. This done, a site is surveyed to find out as much as possible about it and the surrounding area. Second, an excavation may take place to uncover any archaeological features buried under the ground. And, third, the information collected during the excavation is studied and evaluated in an attempt to achieve

606-434: A few of the archeological artifacts are of remarkable character. The extensive museum outdoor area is tied together with gravel walking paths, inviting the visitors to explore the history in a greater content than the exhibition halls alone - to see the reconstructed Chieftain´s house on top of the hill, to go on board the Viking ship, to see the surrounding views and try to grasp the value of the landscape and what it offered in

707-451: A field survey. Regional survey is the attempt to systematically locate previously unknown sites in a region. Site survey is the attempt to systematically locate features of interest, such as houses and middens , within a site. Each of these two goals may be accomplished with largely the same methods. Survey was not widely practised in the early days of archaeology. Cultural historians and prior researchers were usually content with discovering

808-509: A large area (e.g. typically in excess of one hectare , and often in excess of many km ). Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. Archaeological surveys may be: (a) intrusive or non-intrusive , depending on

909-528: A large region or site can be expensive, so archaeologists often employ sampling methods.) As with other forms of non-destructive archaeology, survey avoids ethical issues (of particular concern to descendant peoples) associated with destroying a site through excavation. It is the only way to gather some forms of information, such as settlement patterns and settlement structure. Survey data are commonly assembled into maps , which may show surface features and/or artifact distribution. The simplest survey technique

1010-910: A mobile GIS for referencing, for sampling purposes, and for groundtruth updating directly in the field, resulting a more informed archaeological survey process. Fieldwalking involves picking up scattered artifacts in ploughed fields. In heavily wooded areas such as Scandinavia or the North American Northeast, or deeply alluviated areas as in the Netherlands, fieldwalking is not always a practical method. Humus and fallen leaves in forested areas, silt on alluvial fans, or turf in built-up neighbourhoods may render near-surface artifacts and sites invisible even at short distances. In such instances, archaeological surveyors may concentrate on above-ground structures such as burial cairns, collapsed field walls and rock art panels, look for unnatural changes in

1111-422: A particular locale. It is usually a simple matter to gain permission to perform a cultural field survey, especially a non-intrusive one. If the area is privately owned, the local laws may or may not require the landowners' co-operation. Permission for an intrusive form of survey may be more difficult to acquire, due to the fear of destroying evidence or property values and the threat of lawsuit for said damages from

1212-400: A particular site or a particular kind of archaeological material. For example, they might be searching for a particular shipwreck or an historic fort whose exact location is no longer certain. However, they may also be searching for archaeological materials in particular locations to test hypotheses about past use of those spaces. Sampling surveys , on the other hand, have the goal of obtaining

1313-492: A range of techniques is selected to be applied within an appropriate overarching method. An area may be considered worthy of surveying based on the following: Map regression, comparing maps from different periods of the same area, can reveal past structures that were recorded but are no longer visible as surface features. Using modern maps to transcribe or re-project earlier maps can help to locate these features with contemporary survey controls and techniques. Aerial photography

1414-445: A regional context. A common role of a field survey is in assessment of the potential archaeological significance of places where development is proposed. This is usually connected to construction work and road building. The assessment determines whether the area of development impact is likely to contain significant archaeological resources and makes recommendations as to whether the archaeological remains can be avoided or an excavation

1515-443: A representative sample of some population of sites or artifacts in order to make generalizations about that population. This involves some probability sampling of spatial units, such as random or stratified random sampling of geometrical (often square) or irregular spatial units. Conventionally, fieldwalking in grids or along lines called transects has formed the backbone of archaeological survey fieldwork, at least where visibility

1616-468: A site can all be analyzed using the methods of zooarchaeology , paleoethnobotany , palynology and stable isotopes while any texts can usually be deciphered . Survey (archaeology) In archaeology , survey or field survey is a type of field research by which archaeologists (often landscape archaeologists ) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across

1717-504: A site excavated depends greatly on the country and "method statement" issued. Sampling is even more important in excavation than in survey. Sometimes large mechanical equipment, such as backhoes ( JCBs ), is used in excavation, especially to remove the topsoil ( overburden ), though this method is increasingly used with great caution. Following this rather dramatic step, the exposed area is usually hand-cleaned with trowels or hoes to ensure that all features are apparent. The next task

1818-414: A site reveals its stratigraphy; if a site was occupied by a succession of distinct cultures, artifacts from more recent cultures will lie above those from more ancient cultures. Excavation is the most expensive phase of archaeological research, in relative terms. Also, as a destructive process, it carries ethical concerns. As a result, very few sites are excavated in their entirety. Again the percentage of

1919-408: A sole source. The material record may be closer to a fair representation of society, though it is subject to its own biases, such as sampling bias and differential preservation. Often, archaeology provides the only means to learn of the existence and behaviors of people of the past. Across the millennia many thousands of cultures and societies and billions of people have come and gone of which there

2020-527: A stone wall, will develop more slowly, while those above other types of features (such as middens ) may develop more rapidly. Photographs of ripening grain , which changes colour rapidly at maturation, have revealed buried structures with great precision. Aerial photographs taken at different times of day will help show the outlines of structures by changes in shadows. Aerial survey also employs ultraviolet , infrared , ground-penetrating radar wavelengths, Lidar and thermography . Geophysical survey can be

2121-417: A successful mission completion. The most important parts of the survey are analysis and evaluation. The types of questions that archaeologist often ask of survey data include: what is the evidence for first occupation of an area; when was this area occupied; how are sites distributed; where are sites located; what evidence is there for a settlement hierarchy; what sites are contemporary with each other; how has

2222-487: A systematic guide to the ruins and topography of ancient Rome in the early 15th century, for which he has been called an early founder of archaeology. Antiquarians of the 16th century, including John Leland and William Camden , conducted surveys of the English countryside, drawing, describing and interpreting the monuments that they encountered. The OED first cites "archaeologist" from 1824; this soon took over as

2323-415: A wide range of conditions. While common metal detectors are geophysical sensors, they are not capable of generating high-resolution imagery. Other established and emerging technologies are also finding use in archaeological applications. Although geophysical surveying has been used in the past with intermittent success, good results are very likely when it is applied appropriately. It is most useful when it

2424-495: A wide range of influences, including systems theory , neo-evolutionary thought , [35] phenomenology , postmodernism , agency theory , cognitive science , structural functionalism , Marxism , gender-based and feminist archaeology , queer theory , postcolonial thoughts , materiality , and posthumanism . An archaeological investigation usually involves several distinct phases, each of which employs its own variety of methods. Before any practical work can begin, however,

2525-410: Is a building underneath a field. In such a case, the only way to decide if an excavation is worth the cost is to carefully analyze the evidence to determine which part to trust. On the one hand, the geophysics might just show an old and forgotten water-pipe, but it might also show the wall of just the building the archaeologists were looking for. The analysis therefore includes careful examination of all

2626-405: Is a good tool for planning a survey. Remains of older buildings often show in fields as cropmarks; just below the topsoil, the remains may affect the growth of crops or grass. There should preferably be photographs of the same area at different times of the year, allowing the analyst to find the best time to see cropmarks. If the indicator that started the process was not a record of previous work,

2727-508: Is becoming an increasingly useful and cost-effective tool in archaeology. Geophysical instruments can detect buried archaeological features when their electrical or magnetic properties contrast measurably with their surroundings. In some cases, individual artifacts, especially metal, may be detected as well. Readings taken in a systematic pattern become a dataset that can be rendered as image maps for interpretation. Survey results can be used to guide excavation and to give archaeologists insight into

2828-548: Is bore holes. Small holes are drilled into the ground, most often with hand-powered bores. The contents are examined to determine the depths at which one might find cultural layers, and where one might expect to strike virgin soil. This can be valuable in determining the cost of an excavation - if there is a build-up of several meters of soil above the layers the archaeologist is interested in, the price will obviously be much higher than if artifacts are found only centimeters below ground. One way to classify archaeological field surveys

2929-521: Is fairly good. A single researcher or team will walk slowly through the target area looking for artifacts or other archaeological indicators on the surface, often recording aspects of the environment at the time. The method works best on either ploughed ground or surfaces with little vegetation. On ploughed surfaces, as the soil is turned regularly artifacts will move to the top. Erosion and soil loss on uncultivated and lightly vegetated soil (e.g., in semi-arid environments) may cause artifacts to also 'rise' to

3030-451: Is little or no written record or existing records are misrepresentative or incomplete. Writing as it is known today did not exist in human civilization until the 4th millennium BC, in a relatively small number of technologically advanced civilizations. In contrast, Homo sapiens has existed for at least 200,000 years, and other species of Homo for millions of years (see Human evolution ). These civilizations are, not coincidentally,

3131-492: Is necessary before development work can commence. Archaeologists use a variety of tools when carrying out surveys, including GIS , GPS , remote sensing , geophysical survey and aerial photography . Survey work is conducted for a variety of reasons, some of which are motivated by threats to the preservation of archaeological material. These threats may include proposed land development or risks associated with processes such as decay or erosion. Surveys can also be conducted in

3232-426: Is no one approach to archaeological theory that has been adhered to by all archaeologists. When archaeology developed in the late 19th century, the first approach to archaeological theory to be practised was that of cultural-historical archaeology , which held the goal of explaining why cultures changed and adapted rather than just highlighting the fact that they did, therefore emphasizing historical particularism . In

3333-449: Is prohibitively high. The various Scandinavian sites and monuments registers mainly list above-ground monuments, not ploughed-out sites with scattered pottery. Because of the high costs involved in some kinds of surveys, it is often helpful to use " predictive modelling " to narrow down the search for archaeological materials. This is particularly important for purposive surveys, but can also be used to guide sampling surveys by eliminating

3434-443: Is reflected or emitted from the observed scene. Passive instruments sense only radiation emitted by the object being viewed or reflected by the object from a source other than the instrument. Active instruments emit energy and record what is reflected. Satellite imagery is an example of passive remote sensing. Here are two active remote sensing instruments: The archaeological project then continues (or alternatively, begins) with

3535-428: Is surface survey. It involves combing an area, usually on foot but sometimes with the use of mechanized transport, to search for features or artifacts visible on the surface. Surface survey cannot detect sites or features that are completely buried under earth, or overgrown with vegetation. Surface survey may also include mini-excavation techniques such as augers , corers, and shovel test pits. If no materials are found,

3636-508: Is the 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 –

3737-498: Is the theoretical width of a transect in which the number of artifacts detected outside the sweep is identical to the number missed within the sweep. The poorer the visibility, the poorer the contrast between the artifact "targets" and their surroundings, or the poorer the surveyor's skill or attention, the narrower the sweep width will be. Modern technology such as GPS has made survey recording much easier, as positions of artifacts or artifact clusters ("sites") can be taken well within

3838-655: Is through archaeology. Because archaeology is the study of past human activity, it stretches back to about 2.5 million years ago when the first stone tools are found – The Oldowan Industry . Many important developments in human history occurred during prehistory, such as the evolution of humanity during the Paleolithic period, when the hominins developed from the australopithecines in Africa and eventually into modern Homo sapiens . Archaeology also sheds light on many of humanity's technological advances, for instance

3939-524: Is to divide them into two types: intensive and extensive . The former is characterised by the complete or near-complete coverage of the survey area at a high resolution, most often by having teams of survey archaeologists walk in a systematic way (e.g. in parallel transects ) over parcels of the landscape in question, documenting archaeological data such as lithics , ceramics and/or building remains. However, variations in artifact visibility related to topography, vegetation, and soil character, not to mention

4040-431: Is to form a site plan and then use it to help decide the method of excavation. Features dug into the natural subsoil are normally excavated in portions to produce a visible archaeological section for recording. A feature, for example a pit or a ditch, consists of two parts: the cut and the fill . The cut describes the edge of the feature, where the feature meets the natural soil. It is the feature's boundary. The fill

4141-467: Is used in a well-integrated research design where interpretations can be tested and refined. Interpretation requires a knowledge both of the archaeological record , and of the way it is expressed geophysically. Appropriate instrumentation, field survey design, and data processing are essential for success, and must be adapted to the unique geology and archaeological record of each site. In the field, control of data quality and spatial accuracy are critical to

4242-420: Is what the feature is filled with, and will often appear quite distinct from the natural soil. The cut and fill are given consecutive numbers for recording purposes. Scaled plans and sections of individual features are all drawn on site, black and white and colour photographs of them are taken, and recording sheets are filled in describing the context of each. All this information serves as a permanent record of

4343-552: 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

4444-487: The looting of artifacts, a lack of public interest, and opposition to the excavation of human remains. In Ancient Mesopotamia , a foundation deposit of the Akkadian Empire ruler Naram-Sin (ruled c.  2200 BC ) was discovered and analysed by king Nabonidus , c.  550 BC , who is thus known as the first archaeologist. Not only did he lead the first excavations which were to find

4545-580: The trench method , on several Native American burial mounds in Virginia . His excavations were prompted by the "Moundbuilders" question ; however, his careful methods led him to admit he saw no reason why ancestors of the Native Americans of his time could not have raised those mounds. One of the major achievements of 19th-century archaeology was the development of stratigraphy . The idea of overlapping strata tracing back to successive periods

4646-559: The 1870s. These scholars individuated nine different cities that had overlapped with one another, from prehistory to the Hellenistic period . Meanwhile, the work of Sir Arthur Evans at Knossos in Crete revealed the ancient existence of an equally advanced Minoan civilization . The next major figure in the development of archaeology was Sir Mortimer Wheeler , whose highly disciplined approach to excavation and systematic coverage in

4747-642: The 1920s and 1930s brought the science on swiftly. Wheeler developed the grid system of excavation , which was further improved by his student Kathleen Kenyon . Archaeology became a professional activity in the first half of the 20th century, and it became possible to study archaeology as a subject in universities and even schools. By the end of the 20th century nearly all professional archaeologists, at least in developed countries, were graduates. Further adaptation and innovation in archaeology continued in this period, when maritime archaeology and urban archaeology became more prevalent and rescue archaeology

4848-407: The Chieftain House, was postponed because of the archeological findings of some 2,000-year-old cooking sites and pole holes at the site. Today, the area is excavated and new buildings have been built on the site. This part of the museum comprises 2 permanent exhibition halls and a film theatre. The exhibition halls displays through videos and unique artifacts, the finding and excavation of Borg. Quite

Regional survey in underwater archaeology uses geophysical or remote sensing devices such as marine magnetometer, side-scan sonar , or sub-bottom sonar. Archaeological excavation existed even when the field was still the domain of amateurs, and it remains the source of the majority of data recovered in most field projects. It can reveal several types of information usually not accessible to survey, such as stratigraphy , three-dimensional structure, and verifiably primary context. Modern excavation techniques require that

The administration of Lofotr Viking Museum is located in the former parsonage of the Borge Church. Lofotr Viking Museum is nominated for Museum of the Year 2011 (in Norway) and the European Museum of the Year Award 2013. The Longhouse served as the Pit Stop of the fourth leg in The Amazing Race 23 . Archaeologist Archaeology or archeology

5353-426: The ability to use fire, the development of stone tools , the discovery of metallurgy , the beginnings of religion and the creation of agriculture . Without archaeology, little or nothing would be known about the use of material culture by humanity that pre-dates writing. However, it is not only prehistoric, pre-literate cultures that can be studied using archaeology but historic, literate cultures as well, through

5454-444: The absence of threat as part of a research program or conservation efforts. Prior to engaging in fieldwork, desk-based assessments will likely take place, during which, written, visual, and electronic information is gathered for the purpose of evaluating and developing a plan for future fieldwork. Consideration should be given to the nature of the landscape (vegetation coverage, existing settlement or industry, soil depth, climate) before

Winckelmann has been called both "The prophet and founding hero of modern archaeology " and

5656-410: The archaeologists will need to check if any work has been done prior to commencement of the pending project. As many older surveys and excavations were published in papers that are not widely available, this may be a difficult task. A common way to handle this is through a visit to the area, to check with local museums, historians and older people who might remember something about the former activities in

5757-434: The area surveyed is deemed sterile . Aerial survey is conducted using cameras attached to airplanes , balloons , UAVs , or even Kites . A bird's-eye view is useful for quick mapping of large or complex sites. Aerial photographs are used to document the status of the archaeological dig. Aerial imaging can also detect many things not visible from the surface. Plants growing above a buried human-made structure, such as

5858-560: The artifacts they had found in chronological order. A major figure in the development of archaeology into a rigorous science was army officer and ethnologist Augustus Pitt Rivers , who began excavations on his land in England in the 1880s. Highly methodical by the standards of the time, he is widely regarded as the first scientific archaeologist. He arranged his artifacts by type or " Typology (archaeology) ", and within types chronologically. This style of arrangement, designed to highlight

5959-563: The best-known; they are open to the inquiry of historians for centuries, while the study of pre-historic cultures has arisen only recently. Within a literate civilization many events and important human practices may not be officially recorded. Any knowledge of the early years of human civilization – the development of agriculture, cult practices of folk religion, the rise of the first cities – must come from archaeology. In addition to their scientific importance, archaeological remains sometimes have political or cultural significance to descendants of

6060-473: The early 20th century, many archaeologists who studied past societies with direct continuing links to existing ones (such as those of Native Americans , Siberians , Mesoamericans etc.) followed the direct historical approach , compared the continuity between the past and contemporary ethnic and cultural groups. In the 1960s, an archaeological movement largely led by American archaeologists like Lewis Binford and Kent Flannery arose that rebelled against

6161-643: The empirical evidence that existed for the understanding of the past, encapsulated in the motto of the 18th century antiquary, Sir Richard Colt Hoare : "We speak from facts, not theory". Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment period in Europe in the 17th and 18th centuries. In Imperial China during the Song dynasty (960–1279), figures such as Ouyang Xiu and Zhao Mingcheng established

They proposed a "New Archaeology", which would be more "scientific" and "anthropological", with hypothesis testing and the scientific method very important parts of what became known as processual archaeology . In the 1980s, a new postmodern movement arose led by the British archaeologists Michael Shanks , Christopher Tilley , Daniel Miller , and Ian Hodder , which has become known as post-processual archaeology . It questioned processualism's appeals to scientific positivism and impartiality, and emphasized

His most important methodological innovation was his insistence that all artifacts, not just beautiful or unique ones, be collected and catalogued. William Flinders Petrie is another man who may legitimately be called the Father of Archaeology. His painstaking recording and study of artifacts, both in Egypt and later in Palestine , laid down many of

6464-538: The father of the discipline of art history . The father of archaeological excavation was William Cunnington (1754–1810). He undertook excavations in Wiltshire from around 1798, funded by Sir Richard Colt Hoare. Cunnington made meticulous recordings of Neolithic and Bronze Age barrows , and the terms he used to categorize and describe them are still used by archaeologists today. Future U.S. President Thomas Jefferson also did his own excavations in 1784 using

6565-765: The fifteenth century, and the general accuracy of his records entitles him to be called the founding father of modern classical archeology." He traveled throughout Greece and all around the Eastern Mediterranean, to record his findings on ancient buildings, statues and inscriptions, including archaeological remains still unknown to his time: the Parthenon , Delphi , the Egyptian pyramids , the hieroglyphics . He noted down his archaeological discoveries in his diary, Commentaria (in six volumes). Flavio Biondo , an Italian Renaissance humanist historian, created

6666-528: The first history books of India. One of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey (1626–1697) was a pioneer archaeologist who recorded numerous megalithic and other field monuments in southern England. He was also ahead of his time in the analysis of his findings. He attempted to chart the chronological stylistic evolution of handwriting, medieval architecture, costume, and shield-shapes. Excavations were also carried out by

6767-506: The foundation deposits of the temples of Šamaš the sun god, the warrior goddess Anunitu (both located in Sippar ), and the sanctuary that Naram-Sin built to the moon god, located in Harran , but he also had them restored to their former glory. He was also the first to date an archaeological artifact in his attempt to date Naram-Sin's temple during his search for it. Even though his estimate

6868-485: The human past, from the Paleolithic until the advent of literacy in societies around the world. Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. Derived from Greek, the term archaeology means "the study of ancient history". The discipline involves surveying , excavation , and eventually analysis of data collected, to learn more about

6969-475: The ideas behind modern archaeological recording; he remarked that "I believe the true line of research lies in the noting and comparison of the smallest details." Petrie developed the system of dating layers based on pottery and ceramic findings , which revolutionized the chronological basis of Egyptology . Petrie was the first to scientifically investigate the Great Pyramid in Egypt during the 1880s. He

7070-661: The identification of archaeological sites across a large area, whereas intensive surveys are designed to provide a more comprehensive picture of the location of sites and the nature of off-site data (e.g. field systems , isolated finds, etc.). An intensive survey is the more costly, timely, and ultimately informative of the two approaches, although extensive surveys can provide important information about previously unknown areas. Archaeological field surveys can also be characterized as either purposive or sampling surveys. The former, sometimes also called " archaeological prospection ", involves cases where archaeologists are searching for

7171-454: The imperfect detection abilities of human observers, bring into question the very concept of complete coverage. An extensive survey , on the other hand, is characterised by a low-resolution approach over targets within a study area (sometimes including hundreds of km²). Sometimes this involves a random sampling or some other kind of probability sample to gain a representative sample of the study area. Extensive surveys may be designed to target

7272-472: The importance of a more self-critical theoretical reflexivity . However, this approach has been criticized by processualists as lacking scientific rigor, and the validity of both processualism and post-processualism is still under debate. Meanwhile, another theory, known as historical processualism , has emerged seeking to incorporate a focus on process and post-processual archaeology's emphasis of reflexivity and history. Archaeological theory now borrows from

7373-426: The limits of accuracy and precision necessary for survey work. Recording the position and attributes of archaeological features has been expedited by customizable portable computing interfaces or mobile Geographical Information Systems ( GIS ). Databases containing existing regional archaeological data as well as other landscape GIS layers such as soils, vegetation, modern features, and development plans can be loaded on

7474-444: The lives and interests of the populace. Writings that were produced by people more representative of the general population were unlikely to find their way into libraries and be preserved there for posterity. Thus, written records tend to reflect the biases, assumptions, cultural values and possibly deceptions of a limited range of individuals, usually a small fraction of the larger population. Hence, written records cannot be trusted as

7575-671: The locations of monumental sites from the local populace, and excavating only the plainly visible features there. Gordon Willey pioneered the technique of regional settlement pattern survey in 1949 in the Viru Valley of coastal Peru , and survey of all levels became prominent with the rise of processual archaeology some years later. Survey work has many benefits if performed as a preliminary exercise to, or even in place of, excavation. It requires relatively little time and expense, because it does not require processing large volumes of soil to search out artifacts. (Nevertheless, surveying

7676-448: The modern landscape interfered with the visibility of archaeological remains; what sorts of activities can be recognized (e.g., dwellings, tombs, field systems); how many people lived in this area at any given time or how did population density change over time; why did people choose to live where they did; how has the landscape changed over time; what changes in settlement patterns have there been? However, answering such questions depends on

7777-724: The most effective way to see beneath the ground. Magnetometers detect minute deviations in the Earth's magnetic field caused by iron artifacts, kilns , some types of stone structures , and even ditches and middens. Devices that measure the electrical resistivity of the soil are also widely used. Archaeological features whose electrical resistivity contrasts with that of surrounding soils can be detected and mapped. Some archaeological features (such as those composed of stone or brick) have higher resistivity than typical soils, while others (such as organic deposits or unfired clay) tend to have lower resistivity. Although some archaeologists consider

7878-442: The need to survey areas where, for geological or other reasons, we can reasonably expect all ancient traces to be destroyed (e.g., by erosion) or far too deeply buried (e.g., by alluvium) to be detectable. Modern predictive models in archaeology employ Geographic Information Systems (GIS). A geophysical survey is used for subsurface mapping of archaeological sites. In recent years, there have been great advances in this field, and it

7979-491: The needs of the survey team (and the risk of destroying archaeological evidence if intrusive methods are used) and; (b) extensive or intensive , depending on the types of research questions being asked of the landscape in question. Surveys can be a practical way to decide whether or not to carry out an excavation (as a way of recording the basic details of a possible site), but may also be ends in themselves, as they produce important information about past human activities in

8080-443: The now-destroyed archaeology and is used in describing and interpreting the site. Once artifacts and structures have been excavated, or collected from surface surveys, it is necessary to properly study them. This process is known as post-excavation analysis , and is usually the most time-consuming part of an archaeological investigation. It is not uncommon for final excavation reports for major sites to take years to be published. At

8181-529: The original research objectives of the archaeologists. It is then considered good practice for the information to be published so that it is available to other archaeologists and historians, although this is sometimes neglected. Before actually starting to dig in a location, remote sensing can be used to look where sites are located within a large area or provide more information about sites or regions. There are two types of remote sensing instruments—passive and active. Passive instruments detect natural energy that

8282-682: The past. In broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, and has since become a discipline practiced around the world. Archaeology has been used by nation-states to create particular visions of the past. Since its early development, various specific sub-disciplines of archaeology have developed, including maritime archaeology , feminist archaeology , and archaeoastronomy , and numerous different scientific techniques have been developed to aid archaeological investigation. Nonetheless, today, archaeologists face many problems, such as dealing with pseudoarchaeology ,

8383-653: The patterning of non-excavated parts of the site. Unlike other archaeological methods, geophysical survey is not invasive or destructive. For this reason, it is often used where preservation (rather than excavation) is the goal for project preservation and compliance with applicable laws. The geophysical methods most commonly applied to archaeology are magnetometers , electrical resistance meters, ground-penetrating radar (GPR) and electromagnetic (EM) conductivity. These methods provide excellent resolution of many types of archaeological features, and are capable of high sample density surveys of very large areas and of operating under

8484-698: The people who produced them, monetary value to collectors, or strong aesthetic appeal. Many people identify archaeology with the recovery of such aesthetic, religious, political, or economic treasures rather than with the reconstruction of past societies. This view is often espoused in works of popular fiction, such as Raiders of the Lost Ark, The Mummy, and King Solomon's Mines. When unrealistic subjects are treated more seriously, accusations of pseudoscience are invariably levelled at their proponents (see Pseudoarchaeology ) . However, these endeavours, real and fictional, are not representative of modern archaeology. There

8585-507: The plateau and upper scarp or valley side soils will move down slope, forming a deep seal over low-lying archaeological deposits, rendering them inaccessible to surface survey. Even artifacts on the surface and with relatively high visibility (i.e., little obscuring vegetation), however, are not consistently detected by surveyors. Consequently, it is unrealistic to expect 100% recovery of artifacts or even sites. We can evaluate surveyors' effectiveness at detecting artifacts with "Sweep width," which

8686-550: The precise locations of objects and features, known as their provenance or provenience, be recorded. This always involves determining their horizontal locations, and sometimes vertical position as well (also see Primary Laws of Archaeology ). Likewise, their association , or relationship with nearby objects and features , needs to be recorded for later analysis. This allows the archaeologist to deduce which artifacts and features were likely used together and which may be from different phases of activity. For example, excavation of

8787-449: The property owner. In a non-intrusive survey, nothing is touched, just recorded. An accurate survey of the earthworks and other features can enable them to be interpreted without the need for excavation . An intrusive survey can mean different things. In some cases, all artifacts of archaeological value are collected. This is often the case if it is a rescue survey, but less common in a regular survey. Another form of intrusive research

8888-402: The quality of the evidence, which is why it is important to evaluate the effectiveness and thoroughness of the survey or surveys that contribute that evidence. At times, one part of the survey may not have yielded the evidence one wanted to find. For instance, very little may have been found during a field walk, but there are strong indications from geophysical survey and local stories that there

8989-520: The reconstructed building is 9 metres (30 ft) high. The seat at Borg is estimated to have been abandoned around AD 950. After the excavation ended, the remains of what had once been the long-house remained visible. The long-house has been reconstructed slightly to the north of the excavation site. In 1995, the Lofotr Viking Museum was opened. The museum includes a full reconstruction of the 83-metre (272 ft) long chieftain's house,

9090-475: The sub-discipline of historical archaeology . For many literate cultures, such as Ancient Greece and Mesopotamia , their surviving records are often incomplete and biased to some extent. In many societies, literacy was restricted to the elite classes, such as the clergy , or the bureaucracy of court or temple. The literacy of aristocrats has sometimes been restricted to deeds and contracts. The interests and world-view of elites are often quite different from

9191-403: The surface. Even with optimal surface conditions the efficacy of fieldwalking varies according to long-term land use, topography, weather conditions, the skill and experience of the fieldwalkers, and other factors. Intensive arable agriculture on hilltops will first expose and then pulverize artifacts such as pottery and even chipped stone (typically flint, chert or obsidian) flakes. Conversely,

9292-559: The tradition of Chinese epigraphy by investigating, preserving, and analyzing ancient Chinese bronze inscriptions from the Shang and Zhou periods. In his book published in 1088, Shen Kuo criticized contemporary Chinese scholars for attributing ancient bronze vessels as creations of famous sages rather than artisan commoners, and for attempting to revive them for ritual use without discerning their original functionality and purpose of manufacture. Such antiquarian pursuits waned after

9393-576: The use of metal detectors to be tantamount to treasure hunting, others deem them an effective tool in archaeological surveying. Examples of formal archaeological use of metal detectors include musketball distribution analysis on English Civil War battlefields, metal distribution analysis prior to excavation of a 19th-century ship wreck, and service cable location during evaluation. Metal detectorists have also contributed to archaeology where they have made detailed records of their results and refrained from raising artifacts from their archaeological context. In

9494-472: The usual term for one major branch of antiquarian activity. "Archaeology", from 1607 onward, initially meant what we would call "ancient history" generally, with the narrower modern sense first seen in 1837. However, it was Jacob Spon who, in 1685, offered one of the earliest definitions of "archaeologia" to describe the study of antiquities in which he was engaged, in the preface of a collection of transcriptions of Roman inscriptions which he had gleaned over

9595-513: The vegetation and landscape to decide what may be hidden under the vegetation, or survey by subsurface testing (SST). SSTs can consist of a series of shovel-test pits that penetrate the humus layer or turf or, where substantial later sediments may cover archaeological materials, series of auger or core holes. SSTs are much more costly than fieldwalking, and surveys by SST usually have very low probability of intersecting and detecting archaeological remains unless intensity (density of SSTs), and thus cost,

9696-412: The years of his travels, entitled Miscellanea eruditae antiquitatis. Twelfth-century Indian scholar Kalhana 's writings involved recording of local traditions, examining manuscripts, inscriptions, coins and architectures, which is described as one of the earliest traces of archaeology. One of his notable work is called Rajatarangini which was completed in c.  1150 and is described as one of

9797-525: Was a restlessly itinerant Italian humanist and antiquarian who came from a prominent family of merchants in Ancona , a maritime republic on the Adriatic . He was called by his contemporaries pater antiquitatis ('father of antiquity') and today "father of classical archaeology": "Cyriac of Ancona was the most enterprising and prolific recorder of Greek and Roman antiquities, particularly inscriptions, in

9898-421: Was also responsible for mentoring and training a whole generation of Egyptologists, including Howard Carter who went on to achieve fame with the discovery of the tomb of 14th-century BC pharaoh Tutankhamun . The first stratigraphic excavation to reach wide popularity with public was that of Hissarlik , on the site of ancient Troy , carried out by Heinrich Schliemann , Frank Calvert and Wilhelm Dörpfeld in

9999-423: Was borrowed from the new geological and paleontological work of scholars like William Smith , James Hutton and Charles Lyell . The systematic application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites. In the third and fourth decades of the 19th century, archaeologists like Jacques Boucher de Perthes and Christian Jürgensen Thomsen began to put

10100-421: Was developed as a result of increasing commercial development. The purpose of archaeology is to learn more about past societies and the development of the human race . Over 99% of the development of humanity has occurred within prehistoric cultures, who did not make use of writing , thereby no written records exist for study purposes. Without such written sources, the only way to understand prehistoric societies

10201-504: Was inaccurate by about 1,500 years, it was still a very good one considering the lack of accurate dating technology at the time. The science of archaeology (from Greek ἀρχαιολογία , archaiologia from ἀρχαῖος , arkhaios , "ancient" and -λογία , -logia , " -logy ") grew out of the older multi-disciplinary study known as antiquarianism . Antiquarians studied history with particular attention to ancient artifacts and manuscripts, as well as historical sites. Antiquarianism focused on
