Archaeology

Archaeology is an approach to understanding lost cultures and the mute aspects of human history, without a cutoff date: in England, archaeologists have uncovered the long-lost layouts of medieval villages abandoned after the Black Death in the 14th century and the equally lost layouts of 17th century parterre gardens swept away by a change in fashion. In downtown New York archaeologists have exhumed the 18th century remains of the Black burial ground.

In the study of relatively recent cultures which have been observed and studied by Western scholars, archaeology is closely allied with ethnography. This is the case in large parts of North America, the South Pacific, Siberia, and other places. In the study of cultures that were literate or had literate neighbors, history and archaeology supplement one another for broader understanding of the complete cultural context, as at Hadrian's Wall.

Importance and applicability

Most of human history is not described by any written records. Writing did not exist anywhere in the world until about 5000 years ago, and only spread among a relatively small number of technologically advanced civilizations. These civilizations are, not coincidentally, the best-known; they have been open to the inquiry of historians for centuries, while archaeology has arisen only recently. Even within a civilization that is literate at some levels, many important human practices are not officially recorded. Any knowledge of the formative early years of human civilization - the development of agriculture, cult practices of folk religion, the rise of the first cities - must come from archaeology.

Even where written records do exist, they are invariably incomplete or 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 even of an aristocracy has sometimes been restricted to deeds and contracts. The interests and world-view of elites are often quite different from the lives and interests of the masses. Any 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 of the literate classes, and cannot be trusted as a sole source. The material record is nearer to a fair representation of society, though it is subject to its own inaccuracies, such as sampling bias and differential preservation.

In addition to their scientific importance, archaeological remains sometimes have political significance to descendants of the people who produced them, monetary value to collectors, or simply strong aesthetic appeal. Many people identify archaeology with the recovery of such religious, political or economic treasures rather than 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 where the field has become profitable fodder for entertainment. When such unrealistic subjects are treated more seriously, accusations of pseudoscience are invariably levelled at their proponents. Examples of discredited pseudoarchaeologists include Erich von Däniken and Graham Hancock.

Pseudoarchaeology is indeed an accurate description of much of the amateur archaeology conducted in the 19th century, but the field has changed much since then. These endeavors, real and fictional, are not representative of the modern state of archaeology.

Goals

There is still a tremendous emphasis in the practice of archaeology on field techniques and methodologies. These include the tasks of surveying areas in order to find new sites, and digging sites in order to unearth the cultural remains therein, and classification and preservation techniques in order to analyze and keep these remains. Every phase of this process can be a source of information.

The goals of archaeology are not always the same. There are at least three broad, distinct theories of exactly what archaeological research should do. (These are beyond the scope of the present discussion, and are discussed at length below.) Nevertheless, there is much common ground.

Academic sub-disciplines

Archaeological research is sometimes categorized according to the time period which it studies. Certain civilizations have attracted so much attention that their study has been specifically named. These subdisciplines include Assyriology (the ancient Near East), Classical archaeology (Greece and Rome), and Egyptology (Egypt). In the United States, all branches concerned with civilizations that left behind written records are called historical archaeology.

Prehistoric archaeology concerns itself with societies that did not have writing systems. The term is generally valid only in Europe and Asia where literate societies emerged without colonial influence. In areas where literacy arrived relatively late, it more convenient to use other terms to divide up the archaeological record. In areas of semi-literacy the term protohistoric archaeology can be adopted to cover the study of societies with very limited written records. One example of a protohistoric site is Fort Ross on the northern California coast, which included settlements of literate Russians and non-literate American Indians and Alaska nativess.

Ethnoarchaeology is the study of modern societies resembling extinct ones of archaeological interest, for archaeological purposes. It is often difficult to infer solid conclusions about the structure and values of ancient societies from their material remains, not only because objects are mute and say little about those who crafted and used them, but also because not all objects survive to be uncovered by scholars of a later age. Ethnoarchaeology seeks to determine, for instance, what kinds of objects used in a living settlement are deposited in middens or other places where they may be preserved, and how likely an object is to be discarded near to the place where it was used.

Taphonomy is the study of how objects decay and degrade over time. This information is critical to interpretation of artifacts and other objects, so that the work of ancient people can be differentiated from the later work of living creatures and elemental forces.

A selective list of subdisciplines distinguished by time period or region of study is given below.

• Industrial archaeology focuses on the preservation of material relics of the Industrial Revolution.
• Landscape archaeology involves identifying and studying sites as components in a wider geographical area.
• Maritime archaeology is the study of submerged archaeological sites, including shipwrecks as well as settlements that have been engulfed by bodies of water.
• Middle-Eastern archaeology
• Medieval archaeology is the study of post-Roman European archaeology until the sixteenth century.
• Post-medieval archaeology is the study of material culture in Europe from the sixteenth century onwards.
• Modern archaeology is the study of modern society using archaeological methods, eg the Tucson Garbage Project.

• Archaeometry or Archaeological Science is the application of 'hard' scientific methods to archaeology such as carbon dating, statistics and remote sensing.
• Computational archaeology is the application of computers, particularly GIS, to archaeology
• Experimental archaeology involves attempting to re-enact past processes to test theories about ancient manufacturing, engineering and the effects of time on sites and objects.
• Lithic analysis is the analysis of stone tools, a diverse and abundant type of artifact.

• Paleobotany is the analysis of plant remains (often pollen, a relatively durable carrier of DNA) recovered from archaeological sites.
• Zooarchaeology is the analysis of animal remains.
• Aerial archaeology studying sites from air photos, especially by identifying cropmarks

The application of CRM in the United Kingdom is not limited to government-funded projects. Since 1990 PPG 16 has required planners to consider archaeology as a material consideration in determining applications for new development. As a result, numerous archaeological organisations undertake mitigation work in advance of (or during) construction work in archaeologically sensitive areas, at the developer's expense.

Among the goals of CRM are the identification, preservation, and maintenance of cultural sites on public and private lands, and the removal of culturally valuable materials from areas where they would otherwise be destroyed by human activity, such as proposed construction. This study involves at least a cursory examination to determine whether or not any significant archaeological sites are present in the area affected by the proposed construction. If these do exist, time and money must be allotted for their excavation. If initial survey and/or test excavation indicates the presence of an extraordinarily valuable site, the construction may be prohibited entirely. CRM is a thriving entity, especially in the United States and Europe where archaeologists from private companies and all levels of government engage in the practice of their discipline.

Cultural resources management has doubtless mitigated the destruction of the archaeological record by the ever-sprawling works of Western civilization, but it leaves something to be desired. CRM is conducted by private companies that bid for projects by submitting proposals outlining the work to be done and an expected budget. It is not unheard-of for the agency responsible for the construction to simply choose the proposal that asks for the least funding. CRM archaeologists face considerable time pressure, often being forced to complete their work in a fraction of the time that might be allotted for a purely scholarly endeavor.

History of archaeology

Origins

The exact origins of archaeology as a discipline are uncertain. Excavations of ancient monuments and the collection of antiquities have been taking place for thousands of years. It was only in the 19th century, however, that the systematic study of the past through its physical remains began to be carried out in a manner recognisable to modern students of archaeology. Prior to this, excavation had tended to be haphazard; the importance of concepts such as stratification and context was completely overlooked. In 1803, there was widespread criticism of Thomas Bruce, 7th Earl of Elgin for removing the "Elgin Marbles" from their rightful place on the Parthenon in Athens; but the marble sculptures themselves were valued by his critics only for their aesthetic qualities, not for the information they might supply about Greek civilisation.

Britain was one of the first countries to develop a systematic approach to archaeology and to recognise it as a discipline in its own right (though the debate over whether it is an "art" or a "science" continues). The first individuals to take a serious interest in the subject were clergymen. Many vicars recorded local landmarks within their parishes, and these might include details of the landscape, as well as ancient monuments such as standing stones -- even where they did not recognise the significance of what they were seeing. It is thanks to them that we know about many archaeological features which have since disappeared or been moved. In the sixteenth and seventeenth centuries antiquarians such as John Leland, John Aubrey and William Stukeley conducted surveys of the country, drawing, describing and interpreting the monuments they encountered.

In America, Thomas Jefferson, possibly inspired by his experiences in Europe, supervised the systematic excavation of an Indian burial mound on his land in Virginia in 1784. Although Jefferson's investigative methods were ahead of his time (and have earned him the nickname from some of the "father of archaeology"), they were primitive by today's standards. He did not simply dig down into the mound in the hope of "finding something"; he cut a wedge out of it in order to examine the stratigraphy. The results did not inspire his contemporaries to do likewise, and they generally continued to hack away indiscriminately at tell sites in the Middle East, barrows in Europe and mounds in North America, destroying valuable archaeological material in the process.

A little later, Napoleon's army carried out excavations during its Egyptian campaign. The emperor had taken with him a force of five hundred civilian scientists, specialists in fields such as biology, chemistry and languages, in order to carry out a full study of the ancient civilisation. The work of Jean-François Champollion in deciphering the Rosetta stone to discover the hidden meaning of hieroglyphics proved the key to the study of Egyptology.

A major figure in the development of archaeological method was the Victorian Augustus Pitt Rivers. Archaeology was still an amateur pastime, but Britain's colonial period had provided the opportunity to study antiquities in many other countries. Pitt-Rivers himself, having caught the bug during his military career, brought many artefacts back from overseas and, having inherited a large estate with numerous prehistoric features, collected more artefacts off his own land. From his personal collection (the nucleus of the museum named after him, in Oxford), he developed a typology, something few had thought of doing but which would be of enormous significance for dating purposes.

William Flinders Petrie is another man who may legitimately be called the Father of Archaeology, His work in Egypt developed the concept of seriation which permitted accurate dating long before scientific methods were available to corroborate his chronologies. He was also a meticulous excavator and scrupulous record keeper and laid down many of the ideas behind modern archaeological recording.

Development of archaeological method

The next major figure in the development of archaeology in the UK was Mortimer Wheeler, whose highly disciplined approach to excavation and systematic coverage of much of the country in the 1920s and 1930s brought the science on swiftly. It was not until the introduction of modern technology, from the 1950s onwards that a similar leap forward would be made in field archaeology. Wheeler's method of excavation, laying out the site on a grid pattern, though gradually abandoned in favour of the open-area method, still forms the basis of excavation technique.

Meanwhile, the work of Sir Arthur Evans at Knossos in Crete had shed light on the Minoan civilisation. Many of the finds from this site were catalogued and brought to the Ashmolean Museum in Source | Copyright
