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
726-546: 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
847-401: 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

The beaches of Gower (at Rhossili , for example) and North Devon, such as Croyde and Woolacombe , win awards for their water quality and setting, as well as being renowned for surfing . In 2004, The Times "Travel" magazine selected Barafundle Bay in Pembrokeshire as one of
1089-451: 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
1210-528: 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

The hovercraft is operated by Burnham Area Rescue Boat (BARB) in Burnham-on-Sea . Much of the coastline within the western part of
1573-504: 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
1694-414: 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

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

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

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

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

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
9196-639: The established cultural-history archaeology. 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
9317-620: The evolutionary trends in human artifacts, was of enormous significance for the accurate dating of the objects. 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
9438-533: 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
9559-636: The feasibility of setting up a similar rescue service in Weston-super-Mare . There are also RNLI lifeboats stationed along both sides of the Channel. In the Severn Estuary , in-shore rescue is provided by two independent lifeboat trusts, the Severn Area Rescue Association (SARA) and the Portishead and Bristol Lifeboat Trust. The Bristol Channel and Severn Estuary have the potential to generate more renewable electricity than any other in
9680-746: 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
9801-528: 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
9922-537: The first wife of Hugh Cudlipp the Welsh journalist and newspaper editor. The first person to swim the 30.5 nmi (56.5 km; 35.1 mi) from Ilfracombe to Swansea was Gethin Jones, who achieved the record on 13 September 2009, taking nearly 22 hours. The youngest person to swim from Penarth to Clevedon is Gary Carpenter, who in August 2007 at the age of 17, completed the crossing in 5 hours 35 minutes. He held
10043-498: 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
10164-485: 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
10285-468: 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
10406-472: 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
10527-444: 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
10648-665: 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
10769-593: The marshes around the bay. Around Stert Island the nationally rare compact brome ( Bromus madritensis ) and nationally scarce Ray's knotgrass ( Polygonum oxyspermum ) can be found. The ditches are populated with aquatic and bankside plant species. These include the nationally restricted rootless duckweed ( Wolffia arrhiza ). Other uncommon species such as frogbit ( Hydrocharis morsus-ranae ) and water fern ( Azolla filiculoides ) can also be found. The nationally restricted brackish water-crowfoot ( Ranunculus baudotii ) and sea clubrush ( Scirpus maritimus ) indicate
10890-720: 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
11011-607: The mouth of the River Parrett . At low tide large parts of the channel become mud flats due to the tidal range of 43 ft (13 m), frequently stated to be second only to the Bay of Fundy in Eastern Canada but smaller than those at Ungava Bay , also in Canada. Development schemes have been proposed along the channel, including an airport and a tidal barrier for electricity generation, but conservation issues have so far managed to block such schemes. The largest islands in
11132-575: The name Bristol Channel frequently applied to areas that by the IHO definition are the Severn Estuary, and sometimes to areas of the Celtic Sea. By the IHO definition, the Bristol Channel is about 75 mi (121 km) from west to east. The Bristol Channel–Severn Estuary system extends eastward inland to the limit of tidal influence, at Gloucester Docks . The channel shoreline alternates between resistant and erosional cliff features, interspersed with depositional beaches backed by coastal sand dunes; in
11253-540: The needs of the seafarers on the four hundred sailing vessels in the Bristol Channel and created the Bristol Channel Mission. He raised funds and in 1839 a specially designed mission cutter was built with a main cabin which could be converted into a chapel for 100 people; this later became first initiative of the Mission to Seafarers . Much of the coastline at the western end of the Bristol Channel faces west towards
11374-443: 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
11495-540: The offshore western limit of the Bristol Channel as "a line joining Hartland Point in Devon ( 51°01′N 4°32′W / 51.017°N 4.533°W / 51.017; -4.533 ) to St. Govan's Head in Pembrokeshire ( 51°36′N 4°55′W / 51.600°N 4.917°W / 51.600; -4.917 )". The nearshore limit of the IHO definition is between Sand Point, North Somerset (north of Weston-super-Mare ), and Lavernock Point (south of Penarth , in
11616-529: 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
11737-682: 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 ,
11858-451: The people of England by the great overflowing of the waters or floods ." The cause of the flood is uncertain and disputed. It had long been believed that the floods were caused by a combination of meteorological extremes and tidal peaks , but research published in 2002 showed some evidence of a tsunami in the Channel. Although some evidence from the time describes events similar to a tsunami, there are also similarities to descriptions of
11979-693: 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
12100-550: 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
12221-498: The record for the fastest swim across the Bristol Channel until 2020. Carpenter's coach, Steve Price, was the first person to swim from Penarth to Clevedon, in 1990. In 2020 Joanne Jones swam from Penarth to Clevedon in a time of 5 hours, 27 minutes. Joanne was the first woman to swim this route, and holds the current record for fastest time. 51°21′N 3°42′W / 51.350°N 3.700°W / 51.350; -3.700 Archaeology Archaeology or archeology
12342-441: The reserve is accessible via a waymarked public footpath, and the South West Coast Path begins at Minehead at the western end of the bay. The tidal range holds potential for energy generation and plans for a tidal barrage in the bay have been considered. Hinkley Point is a headland extending into Bridgwater Bay 5 miles (8.0 km) west of Burnham-on-Sea, close to the mouth of the River Parrett. The landscape of Hinkley Point
12463-440: The reserve. The populations of Eurasian whimbrel ( Numenius phaeopus ) and black-tailed godwit ( Limosa limosa ) are internationally important. Significant populations of dunlin ( Calidris alpina ) and wigeon ( Anas penelope ) also frequent the bay. In early winter the wigeon select Puccinellia maritima in preference to Agrostis stolonifera and Festuca rubra . Avocets have become regular autumn and winter visitors to
12584-472: The road and rail crossings of the Severn estuary. The Channel can be a hazardous area of water because of its strong tides and the rarity of havens on the north Devon and Somerset coasts that can be entered in all states of the tide. Because of the treacherous waters, pilotage is an essential service for shipping. A specialised style of sailing boat, the Bristol Channel Pilot Cutter , developed in
12705-495: The slightly brackish nature of the water. Brean Down is a site for the nationally rare white rock-rose ( Helianthemum apenninum ), which occurs in abundance on the upper reaches of the grassy south-facing slopes. Some of the broomrapes growing near Bridgwater Bay, which were originally thought to be oxtongue broomrape ( Orobanche artemisiae-campestriae ), are now no longer believed to be this species, but atypical specimens of ivy broomrape ( Orobanche hederae ) Other plants on
12826-414: The southern slopes include the Somerset hair grass , wild thyme , horseshoe vetch and birds-foot-trefoil . The northern side is dominated by bracken , bramble , privet , hawthorn , cowslips and bell heather . Five Red Data Book invertebrate species have been recorded in the area. These include: soldier flies Odontomyia ornata and Stratiomys singularior , hover fly Lejops vittata ,
12947-475: 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
13068-462: The swim, nominally 11 miles but equivalent to 22 miles because of tidal flows, in 7 hours 20 minutes. In 2007 the achievement was marked by a plaque on the seafront at Penarth. There is also a plaque at Anchor Head in Weston-super-Mare. In 1929, Edith Parnell , a 16-year-old schoolgirl, emulated Kathleen Thomas's swim from Penarth to Weston-super-Mare in 10 hours 15 minutes. Edith later became
13189-555: 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
13310-499: The twelve best beaches in the world. In 2007, Oxwich Bay made the same magazine's Top 12 best beaches in the world list, and was also selected as Britain's best beach for 2007. The city of Swansea is the largest settlement on the Welsh coast of the Bristol Channel. Other major built-up areas include Barry (including Barry Island ), Port Talbot and Llanelli . Smaller resort towns include Porthcawl , Mumbles , Saundersfoot and Tenby . The cities of Cardiff and Newport adjoin
13431-576: 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
13552-472: 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
13673-553: The west. On the beach near Stogursey are the remains of a submerged forest dated to 2500 BC. - 6500 BC. Brean Down is a promontory marking the eastern end of the bay. Made of carboniferous limestone , it is a continuation of the Mendip Hills , and two further continuations are the small islands of Steep Holm and Flat Holm . It is owned by the National Trust , and is rich in wildlife , history and archaeology , as well as being
13794-457: The world, built in 1947. The steamer provides pleasure trips between the Welsh and English coasts and to the islands of the channel. Trips are also offered on the MV ; Balmoral , also owned by Waverley Excursions. The Burnham-on-Sea Area Rescue Boat (BARB) uses a hovercraft to rescue people from the treacherous mud flats on that part of the coast. A hovercraft was recently tested to determine
13915-412: 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
14036-516: 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
14157-421: 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
14278-491: Was also the last site in England used for 'mudhorse fishing'. There are several small harbours along the coast. The low-lying areas of the bay have been subject to flooding, including the Bristol Channel floods of 1607 and many times since particularly around the Steart Peninsula . In response to this threat sea walls have been built at several points including at Burnham-on-Sea , Berrow and Blue Anchor to Lilstock Coast . The extensive mud flats and high tidal range have been
14399-423: 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
14520-421: 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
14641-504: 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
