Public Archaeology: Butser Experimental Ancient Farm, southern England


 “There is a trend toward teachers understanding the different ways of learning… Written materials are not the only way”.
 ~ Maureen Page, Director of Butser’s School Education Program 

Introduction

In several earlier posts, I talked about the benefits of public education in archaeology (For more information, see here and here). Experimental archaeology is one of the more recently developed directions in archaeological research, although archaeologists are now becoming aware that one of the most effective ways to engage the public and to understand the past is to try to reconstruct it as accurately as possible. Educators are also realizing that not all students learn the same way via written materials and that hands on experience-based activities raise both interest and cognitive learning. An example of this would include the innovative and long-term research project at Butser Ancient Farm, Hampshire, in southern England. Butser Experimental Farm provides unique opportunities for the public and students to take part in organized experimental archaeology activities. The site is a working replica of an Iron Age farm settlement with earthworks, ancient structures, crops and livestock, in order that the agricultural and domestic economy of the late prehistoric period in Britain can be studied. Visitors are encouraged to participate in any of the practical sessions, such as prehistoric agriculture (grinding corn), animal husbandry (feeding livestock), and manufacturing (pottery making, metal and charcoal production and spinning). Peter Reynolds, former director of Butser, expressed that essentially experience is probably the best teacher of all. Some time ago, I personally attended one of their residential archaeology courses and I doubt that I would have learned as much from solely a didactic presentation (See insert box below for further details). Butser continues to provide a wide variety of quality courses, demonstrations and events for the public (of all ages) and is worth a mention here.



A short background to Butser

The late Dr. Peter Reynolds (1939-2001) established the long-term research project for Butser Ancient Farm in 1972, with the initial support of sponsors such as the Council for British Archaeology (CBA). The project was set up specifically as a program for research and education, and the goal was to construct a practical working version of an ancient farm in order to study the domestic and working structures, manufacturing activities, crops, and domestic animals of the Late Iron Age and early Roman periods (c.400BC to 400AD in Britain). The project was devised from evidence excavated from archaeological sites and the results from Butser experiments were to be compared with archaeological remains in order to test ideas put forward by archaeologists. Butser is not an archaeological site or a museum, but an open-air research laboratory for archaeology, where the Romano-Celtic World is being investigated by full-scale experimentation using the techniques and materials available at that time (but also by applying modern technologies such as magnetic susceptibility, mass spectrometry and computers to enhance archaeological practice). Continual experimentation with the changing seasons, as well as corrections in archaeological theory, means that the farm is in a dynamic state of change, as opposed to merely representing a static reconstructed prehistoric settlement.

Based on archaeological remains from sites such as Little Woodbury in Wiltshire, Moel y Gerddi in Wales, and Sparsholt in Winchester, Butser has been able to reconstruct several types of building, such as Iron Age round houses and a Roman villa with a working hypocaust (under-floor heating). Although reconstruction is often an imperfect product of our time and archaeological truths are debatable, Butser nevertheless endeavors to perfect the work they present in order to make them as historically accurate and as relevant as possible. For instance, Maureen Page, Director of Butser’s School Education Program, says that there are no other sites in the whole of the UK that use original building materials to the same extent as those used for the Roman villa at Butser Farm. Similarly, prehistoric types of crops and livestock or their nearest equivalents have been brought to Butser.

Although the Ancient Farm has now been in operation for 38 years, it hasn’t always occupied the same site. Its initial location was on Butser Hill in Hampshire (from where it takes its name) and a second site was opened in 1976 at Hillhampton Down in order to better accommodate the visiting public. In 1991 the whole project finally moved to its present location on Bascomb Copse at Chalton, Hampshire. Butser Ancient Farm is now operated independently by Butser Education CIC, and since moving to its present location, economic support is solely obtained through its educational programs. Despite the recent economic downturn, Butser is able to continue its original mission of carrying out quality experimental research and educational activities. Indeed, Butser is witnessing a continual increase in visitor numbers, particularly secondary school students this year. The site has also managed to rebuild four Iron Age round houses in the enclosure and also has plans for a fifth, as well as a new visitor center by September.

What programs do they offer?


Butser offers a variety of fascinating and unique hands on experienced-based educational activities for school groups, educators, undergraduates, graduate students, archaeological societies, special interest groups and the general public. The vast numbers of visitors that Butser receives every year attests to the quality of programs they consistently provide. More than 14,000 school children are welcomed to the site each academic year, in addition to scores of others who participate in workshops or special events. For primary school children up to age 11 (Key stages 1 and 2), sessions meet many aspects of the national curriculum by assisting with general education issues. Children can explore technologies from the ancient world of the Iron Age Celts and the Romans, enabling them to make connections with different societies. Such awareness can help diminish stereotypical beliefs about people who existed in the past and influence children’s consideration of other people and their heritage. The farm’s educational component can also assist with numerous parts of the school curriculum for secondary children up to the age of 16 (Key stages 3 and 4). For instance, the pre-Roman periods are not readily included within England’s national curriculum, but the core subject of history can cover prehistoric life, the Iron Age Celts, Romans and early civilizations. Children are encouraged to use complex thinking skills by contributing to discussions about their experimental research.
“We encourage children not only to use their imaginations but also, as far as possible, to use their five senses to experience what it might have been like living in those far off times. The Schools Educational Programme is directed to meet several of
the specific requirements of the National Curriculum…” ~ Butser Education CIC

All visits begin with a preparatory talk in one of the distinctive Iron Age round houses or in the Roman villa, before students become actively engaged in any hands-on activities. Unlike traditional teaching methods, students aren’t simply the passive receivers of information, but are able to actively learn through their own experiences at Butser (learning through doing). The site intentionally omits offering classroom materials to students or teachers, so as not to be distracting in any way. The one-day sessions are selected in collaboration with school teachers and can be tailored to meet particular requirements. Although England’s curriculum contains core subjects with key concepts and processes, the programs of study are not rigid, and offer broad parameters for content. Teachers are therefore given more autonomy to develop creative learning methods in schools. There exists a collaborative effort between Butser’s educational program and schools in order to develop suitable curriculum methods. Teachers are encouraged to devise their own follow up lesson plans from their visit to the farm. Likewise, although Butser has its own research agenda and is not specifically driven by educational requirements, it nevertheless continues to respond to the changing needs of education. Although the teaching of heritage stewardship is not a major component of Butser’s agenda, it is nevertheless briefly mentioned in their courses.

Despite the subject of archaeology no longer being taught in schools at GCSE level (only at A Level and beyond), Maureen Page was pleased to say that experimental archaeology has now become mainstream within many college archaeology courses in the UK. In fact, Butser offers a variety of experiences for sixth form students and students from colleges and universities. The site also has workshops for the general public (of all ages), which entail hands-on experience in ancient crafts and archaeological methods with qualified instructors. Although such workshops cover similar themes to those that I attended during the 1990s (See insert box for further information), financial constraints mean that five-day residential courses are no longer offered. One or two-day courses are however available, but accommodations are now recommended off-campus. Special events are also available, and can sometimes include food and celebrations with story telling or singing, or perhaps even the chance to try your hand at using ancient weapons. Those who sign up for Butser can also enjoy the unique and evocative setting amongst or within reconstructed Iron Age round houses and a Roman Villa, as well as a variety of crops and animals similar to those found in the Iron Age (such as Emmer, Spelt and primitive sheep called Soay).




Charcoal Clamp at Butser Ancient Farm (c. 1994)
This pyramid fire was covered with straw and then soil in order to keep air out, thus preventing combustion of the wood inside. The fire burned slowly for about 36 hours, so that the timber would reduce into carbon to produce charcoal.

My early experience at Butser Ancient Farm

Some time ago, I attended a workshop called “Fire, Clay and Metal”, which was mainly aimed at examining the role of fire in prehistory and the Roman period and the development of metallurgy. Topics included the agricultural use of fire, pottery production and kiln construction and firing, as well as practical work in the production and alloying of metals from base ores using bowl and shaft furnaces.

Despite attending this workshop a very long time ago, it left a positive and everlasting impression, to such an extent that some of the supplementary early technology courses I later attended with my first degree seemed somewhat inferior by comparison. I was fortunate to be able to spend my then five-day residential course working in a relatively small group that was directed by the wonderful Dr. Peter Reynolds. At the start of each day we received appropriate instruction for the topic at hand before embarking onto our lively experiments. The course was so comprehensive that we not only refined our clay in order to make pottery, but we also constructed a charcoal clamp and Iron Age pottery kiln before firing our own handiwork!

Despite Pete’s unwelcome departure, I am pleased to hear that Butser Ancient Farm’s educational component is still thriving and continues to offer many stimulating and quality experienced-based activities to people of all ages and aptitudes.



Conclusions


Although the real past will always elude us and we will never know EXACTLY what it was like to live in the Late Iron Age and early Roman periods of Britain, for almost 40 years Butser Ancient farm has been effective in offering a fascinating insight into ancient times. The research conducted within such a distinctive and stimulating environment offers a unique teaching tool that can also address many curricula concerns (such as science, history, art, literacy and numeracy). Butser’s innovative educational programs connect with the public through exciting hands-on learning opportunities, and have introduced thousands of people to experimental archaeology. Butser has also significantly improved our understanding of the Celtic and early Roman periods of southwestern England, as well as many other aspects of the remote past.

The hands-on experimental approach at Butser is offered at all levels (pre-college, college and for the adult public) and is suitable for all ages and abilities. Indeed, there is something for everyone at Butser Ancient Farm, no matter the level of interest possessed in the field of archaeology or education. Although pre-college school has ended for this academic year, it’s never too early to plan for next year so that you don’t miss out next time. Also, there still time to sign up for many workshops and special events in 2010 (some sessions may be booked in advance). In July, there is a practical archaeology weekend school, which provides an introduction to archaeological excavation and recording methods. There is also a workshop to observe the common herbs grown in the Roman home, or a lecture and presentation on Roman cooking where attendees may participate in the preparation of a Roman feast in the villa kitchen. Courses are also available on metal production, pottery making, coracle construction, or cave painting, and much, much more. Special events activities include a weekend to observe skilled flint knappers from the Lithic Studies group, an open weekend where Butser will be cooking various foods for visitors to taste, or Samhain Celebrations (Festival of the Dead), involving story telling and a live band in the ‘Great Round House’.

Why Teach Archaeology at Precollegiate Level?



A generation which ignores its history has no past and no future ~ Robert Heinlein

A number of years ago I was involved in assessing the effectiveness of the Bureau of Land Management’s (BLM) Heritage Education Program, Project Archaeology: Intrigue of the Past, at the precollegiate level in Colorado. (The program had also been used in the states of Oregon, Utah and New Mexico). Although my sample size was small due to the lack of valid responses received from educators in Colorado, my evaluation data (cautiously) confirmed that the program was basically effective at the precollegiate level. I recently followed up with this program and I’m happy to say that it is doing very well. The Project Archaeology Program (PA) is now in partnership with Montana State University (MSU) and has become a national phenomenon. Amendments to the materials are continually being made in order to enhance its effectiveness, and the first of three new sets, PA: Investigating Shelter has recently been published and is now available. Further information can be obtained here.

This exciting follow up has spurred me on to write a post about the importance of teaching archaeology in the classroom. 

A short introduction

The benefits of public education in archaeology have been known for some time. However, in both the United States and Great Britain, the subject of archaeology is still not included within pre-college education as a separate subject (aside from post-16 A Levels in England and Wales). In today’s world, teachers not only have the task of teaching curriculum subjects, but they are also challenged by countless other issues, such as keeping up with the constant progression in computer technology, coping with children with special needs (e.g., ADHD, dyslexia or autism), dealing with school bullying, and making sure that their students meet the requirements of national and local curriculum standards. It is no surprise, therefore, that teachers are reluctant to add an entirely new field of study into their already overburdened classroom agendas, especially one that is viewed to be somewhat esoteric.  Additionally, financial constraints usually mean that archaeology programs rarely receive major budget allocations or grants, and those already in existence are usually the first to be terminated when considerable cut backs are made. Nevertheless, recognition of the need for more, and better public education about archaeology is emerging throughout both the US and the UK, as it is acknowledged that an improved public understanding of archaeology will result in the appreciation of archaeological sites and data, and thus less destruction of the archaeological heritage by the uninformed, such as pothunters, curio-seekers, and vandals. Precollegiate students and teachers form a segment of the general public that have become a key audience for archaeologists to instill their subject matter into formal classroom curricula. Not only does virtually every future adult initially experience early life as a student, but the resulting inquisitiveness from children can often have an influential effect on the attitudes of adults, such as parents, and grandparents. Researchers therefore believe that this is the most effective means for the transmission of heritage education standards and ethics to the general public. 

What is archaeology?

Before discussing the importance of archaeology education in pre-college classrooms, it may be helpful to define what the term “archaeology” means. Many people have described archaeology in numerous different ways over time. Some discrepancies are probably the result of the way in which the past was previously studied and how it has continually changed to develop into a more scientific endeavor, whilst also becoming more concerned with human behaviors. Others, however, view it according to their own personal experiences, either as professional archaeologists, indigenous communities, or as interested members of the general public. In order to maintain public interest in the subject, therefore, it is crucial that professional archaeologists empathize and cooperate with other people’s views. For the purpose of this post, I have endeavored to provide a very basic outline of archaeology, so that a fundamental understanding of the subject can be grasped:

Archaeology involves the scientific study of past human cultures through the material objects (artifacts) that were left behind, and the physical remains of the natural environment in which they were connected (faunal and floral remains, soils, and so on). The term culture defines the shared customs and behaviors that exist, including language, belief systems and technologies. Archaeological remains provide clues about when a site was occupied and the way people were living (for instance, about social organization and cultural change). Although written records may sometimes help, in some cases (particularly in the US) no such records exist. Archaeology can thus be used to study the prehistoric past, prior to when written evidence begins, as well as during the historic part of history to support written documents. Archaeology is thus a multicultural discipline, which encourages respect for past and present human populations, and is a means of conserving our shared human heritage by providing individuals with viewpoints about their own links with the past.

Why is it important to teach archaeology in schools?

Education in archaeology can serve several purposes:

1) First, it can be used to fight the increasing problem of damage to archaeological remains, as a result of vandalism, looting, unscientific digging, insensitive development, destruction from natural forces, or simple neglect, by promoting a sense of responsibility and stewardship of the cultural heritage. Archaeology involves the study of the nonrenewable and fragile remains of past cultures, and it is a useful way to encourage awareness about the need to protect archaeological sites. It is being ever more recognized that archaeological sites are being destroyed at an alarming rate. Although legislation and regulation (for example, the National Historic Preservation Act in the U.S. and the Department of the Environment’s planning system currently under major reform in the U.K.) exist in order to deter some pothunters, experts believe that preventative measures such as education in archaeology would be more successful at protecting our heritage than threats of fines or jail sentences. Problems occur when people do not understand that their own explorations can permanently damage archaeological sites. They do not appreciate that artifacts, which are removed from their original depositional context, lose much of what they can tell us about the past. Further, many people are inclined to collect the most eye-catching artifacts (for example, arrowheads or decorated ceramics) without realizing that the loss of the artifact, much less an entire class of artifacts from a site or even region, can seriously impede what can be learned about an archaeological site as a whole. Indeed, many of the uninitiated are under the impression that archaeologists take finds home in order to expand their personal collections! This brings us to the second reason.


2) Teaching archaeology in schools can extinguish many of the myths about what archaeology entails. Although increased awareness from popular movies, such as the “Indiana Jones” series or “Lara Croft Tomb Raider” has brought archaeology to the attention of both the American and British Public, such exotic depictions stray significantly from reality. The word, “archaeology”, to most of the lay public evokes many stereotypical images about handsome and rugged adventurers, seeking buried treasure in dangerous terrain and ancient ruins, as well as a variety of tug-of-war skirmishes thrown in just for good measure. Too often misrepresentations by the media contribute to such misconceptions by focusing on the most sensational aspects of the profession, such as spectacular ruins and unusual artifacts that capture the imagination. More ordinary finds such as fragments of clay pipe or pottery sherds are rarely reported. In the real archaeological profession, spectacular discoveries are uncommon, and work usually involves a combination of demanding physical labor and meticulous research. (In fact, I recall one incident long ago where strangely our team did come across something very shiny amongst some Pre-Roman British Iron Age deposits in the south of England. We were extremely excited at such an oddity and continued to carefully trowel, only to find that a dismantled Austin Morris A30 car had contaminated the stratigraphy! Such a scenario is in fact more realistic than finding buried treasure.)

Moreover, a popular belief is that archaeologists spend all of their time excavating. More than a few have assumed that my days as an archaeologist would involve solely digging around in the dirt (or exhuming some mysterious tomb in Egypt, or even worse, digging up dinosaurs). Essentially, archaeologists spend a fairly small amount of time excavating, compared to that spent analyzing and interpreting sites and finds, and preparing technical reports. In fact, the whole archaeological process starts well before any dirt is even removed from the topsoil, depending on what research questions there are. Experts say that it is indeed this misrepresented idea of archaeology that interferes with efforts to establish archaeology into the precollegiate curriculum, as it is erroneously presumed to be far too complicated or expensive. Such a notion that archaeology is just a bit of fun and teachers should get students involved in digging up some sort of feature on their school grounds can also unwittingly produce a generation of pothunters. It is therefore crucial to include the public in a wide range of resource types in order to produce future generations who have a better understanding of the great need for the protection of the archaeological heritage from the menace of unskilled excavations.

3) It is further recognized that teaching prehistory can lessen stereotypical views about people who lived in the past, influencing students’ consideration of other people and their heritage. Many children believe that women contributed little to the modern world, and that non-whites have no history. Such attitudes relating to racial or gender-role identity are harmful, as they dehumanize people by disregarding the distinctiveness and value of their cultures. For instance, in the US, the subject of history generally begins with the arrival of Christopher Columbus on San Salvador in 1492, excluding the larger part of human occupation in the Americas. Focusing solely on the written past not only ignores Native American cultures, but also overlooks other Americans who were deprived of formal education up until the beginning of the last century. Everyone’s past is important and should be impartially included in pre-college classrooms. Archaeology education enables a way of examining the life ways of indigenous peoples before and after European contact in the US.  In my opinion, teaching the past using the single method of the written record, but excluding the archaeological evidence, is akin to teaching reading and writing with the use of only consonants and the exclusion of vowels! To acquire a better comprehension of the whole subject, it is important to use all tools available.

4) Archaeology is a superb way to gain student’s interest, while also addressing many educational concerns in the classroom. Archaeology presents real evidence and artifacts concerning actual people from the past, stimulating enthusiasm and generating feelings of intrigue, adventure and discovery. As well as making formal education more exciting, it is known that archaeology encourages complex thinking and team building skills, and it is broad-based in nature, enabling it to be effectively taught across traditional school subjects. Teachers find archaeology useful for enhancing a range of subjects for students of many ages and abilities, including geography, history, science, social studies, art, mathematics, citizenship and language arts. Students also find archaeology lessons intellectually engaging. Research has also shown that students who learn about the past through archaeology and its multidisciplinary hands-on activity-based nature (with teacher guidance), as opposed to the alternative traditional and passive textbook-based approach, tend to advance more cognitively, are likely to retain more information, and find such studies more rewarding classroom experiences.

Conclusion

Archaeology in precollegiate education is a very worthwhile technique, which corresponds well with curriculum needs and state requirements making it more acceptable to professional educators. Students are generally interested in learning about the subject, and in their excitement are often keen to tell others about it, thus encouraging a broad spectrum of the public to respect our heritage resources. It seems therefore that the multidisciplinary subject of archaeology can increasingly make a large impact on precollegiate education. The creation of programs to spread positive messages about the value of our nonrenewable cultural resources should be considered a fundamental component of most public schools, in order to secure the future of our past. Although the subject of archaeology is not yet taught as a separate subject in its own right at precollegiate level in the US and UK, the good news is that there is an increasing number of organizations (both government agencies and individual archaeologists) who have made the effort to increase the availability of appropriate curricula resources for archaeology education. It is not in the scope of this post to list them all here, but I have provided a few links below for further information.

Some Refitting Studies At Boxgrove, West Sussex, England



In my last post, I discussed the topic of refitting ancient stone tools and how such studies can provide us with important information about past human activities (see previous post). In this article, I would like to take the subject one step further and to show how refitting has been applied to the middle Pleistocene site of Boxgrove, and how it has helped improve our understanding of early human organization in the production of stone tools. Although a number of refitting studies have been carried out at Boxgrove, I will focus on a project that I previously completed relating to a specific part of the site, called Unit 4C, Area Q/2D (thanks to the cooperation and support of Mark Roberts, Norah M. Moloney, Michael J. Shott, Chris Bergman, Francis Wenban-Smith, Nick Ashton, Darren Lankstead and Matthew Pope).

A short introduction to Boxgrove

The Acheulean site of Boxgrove is located in a stone quarry in West Sussex, England. It has been dated to around 500,000 years ago, and has been under ongoing investigation by the Institute of Archaeology Field Unit (University College London) since the early 1980s (under the direction and of Mark Roberts and Matthew Pope). The main archaeological or soil horizon (within what is referred to as Unit 4 or the Slindon Silt Member) contains large numbers of flint artifacts, and is associated with being occupied by Acheulean flint knappers. The lithics for my refitting study came from this unit in Area quarry 2 (See diagram below).


The lithics studied from Area Q2/D comprised almost entirely of more than 700 flakes. Over a hundred refits were obtained by systematically conjoining the flakes, much like a 3-D jigsaw puzzle.

The depositional integrity of the area

To determine whether the artifact concentrations related to early human activities, as opposed to simply disturbances via natural agents (such as burrowing animals, plant roots or water flow), the distribution of refitted flakes were recorded in detail. Lithic finds were counted and plotted on graphs, and then distances were measured between refitted flake pieces. Most of the refits were found to be in close proximity to one another, and when results (such as the distribution of artifact size and the total number of refits obtained) were compared to other site studies, it was established that the artifacts had suffered relatively little movement and could generally be associated with past human behavior.

Organization within the site

In order to learn more about the early cognitive abilities of the flint knappers in this area, flake-reduction sequences and the nature of manufacturing technology were observed. Flakes were first set apart according to whether they had been produced by soft (i.e., both soft organic and soft stone materials) or hard (i.e., hard stone) hammer percussion. Interestingly, it was determined that over half of the flakes had been produced by soft hammer percussion, and that most of the debitage came mainly from stage 2 of the reduction sequence (trimming and shaping). Such findings can have many implications for hominid behavior. The use of both soft and hard hammer percussion modes would imply that they undoubtedly possessed divergent levels of skill. Also, if bones or antlers were utilized, these would not have been as commonly available as stone for convenient use, and it may therefore imply that these early humans carried out some form of mental planning. It must be noted, however, that there are some limitations to distinguishing between different types of percussor, and soft cortical flint nodules may well have produced the same characteristics as antler or bone. Nevertheless, the fact that many antler and bone soft hammers have been found frequently at Boxgrove would suggest that such an assumption would not be implausible.

Spatial distribution of lithics across the landscape

The characteristics of assemblage composition were compared with another adjacent unit area (Q/2A) to find out if there were any connections between the two. Such an examination can provide clues about behavioral patterns such as planning and mobility in transport distances, and this is particularly important for the Palaeolithic period. Studies of the debitage from Area Q/2A came from stage 3 of production (final modification of the tool), whereas Area Q/2D has been used particularly for stage 2 of the reduction sequence (trimming and shaping).  It would seem that stage 1 (acquisition and roughing out of the nodules) had been performed elsewhere. This implies that flint knappers exploited certain areas for particular stages of production, and then the unfinished tools were transported to other areas for the next stage of the reduction process. This again tells us that a certain level of forethought had been involved in the planning of the tool from the conception to completion.

Summary

Despite its limitations (when it comes to understanding site formation processes, recognizing discrete stages of the reduction process and distinguishing between hard and soft hammer percussion modes), refitting analysis of lithic artifacts from Area Q2/D has demonstrated that it can provide many useful insights relating to the cognitive abilities of the earliest colonizers of Northern Europe around half a million years ago (as previously attested by work in other areas at Boxgrove).

Putting the Pieces Together: Refitting ancient stone tools

A SHORT HISTORY OF REFITTING

“Refitting” (sometimes also known as “conjoining”) can be traced back to F. C. J. Spurrel’s work at the Palaeolithic site of Crayford, England, in 1880. However, the technique’s potential has now become more widely known, thanks mostly to the relatively recent work at several later Stone Age sites, such as Pincevent and Meer in Europe, Kapthuring and East Turkana in Africa, and the Negev Desert in Israel.

WHAT IS REFITTING?

The creation of chipped stone tools involves a reduction sequence, which is characterized by the cumulative removal of raw material. When flaking stone, each stage involves the reduction of the original mass and the creation of tool fragments or manufacturing debris. This process of stone reduction is always irreversible, as each removal is permanent. Although it may be possible to make some adjustments along the way, unlike other materials such as metal or clay, it is not possible to start again with the original mass. The knapper, therefore, needs to plan his approach carefully, so that the best results are obtained during the reduction process. The basic stages of the reduction sequence include: procurement of the raw material and preliminary roughing out, trimming and shaping, and then final modification of the tool. Another (European) term for this sequence is called chaîne opératoire, although the name also includes the stage that occurs after completion of the finished tool (i.e., the maintenance/modification of the tool through use and final discard of the artifact). Lithic materials preserve well on archaeological sites due to their inorganic nature, enabling evidence from every stage of the reduction process.

Refitting includes at least partial reconstruction of the pieces of stone so that they almost resemble their original form. Flakes that have been struck from a core can be reassembled, by rejoining or fitting pieces together, much like a 3-D jigsaw puzzle. Although the process can be very tedious and time-consuming, it has the potential to tell us many things about past activities.


WHAT CAN IT TELL US?

Traditionally, refitting has been used to help reconstruct artifacts for illustrative or display purposes, or in order to obtain a better appreciation of the artifact’s original appearance. Refitting studies are now, however, being used to glean a greater understanding of archaeological record. By employing refitting studies, archaeologists are able to make inferences about:

* The depositional integrity of the area
It is possible to establish that the artifact concentrations were not merely the result of natural disturbances, but surviving evidence relating to human activity. For example, tight spatial clustering of refitted material would imply that there was little disturbance of the area.

* Organization within the site
Flake-reduction sequences and the nature of manufacturing technology within different parts of a site unit can be distinguished. For instance, large flakes with completely cortical dorsal surfaces would indicate that the very beginning of the reduction process was carried out in that area. Insights about early cognitive abilities may also be obtained from the use of manufacturing technology, such as hard-hammer (stone) or soft-hammer percussion (entailing the use of antler, bone or wood).

* Spatial distribution of lithics across the landscape
Archaeologists can compare the different characteristics in assemblage composition between two different unit areas in order to find out whether there are any associations. This may provide clues relating to behavioral patterns, such as forethought and mobility in transport distances, which is particularly important for the Palaeolithic period. For instance, two separate areas may have been used for particular stages of tool production.


WHAT DOES THE REFITTING PROCESS ENTAIL?

Although refitting has been used on a variety of materials (pottery, bone, shell, glass, metal and wood) and can involve various methodologies, for the purpose of this post I will discuss the approach I have used for stone tools.

First and foremost, it is important to ensure that all pieces to be refit are labeled accordingly, so that they can be properly returned to the correct storage container at the end of the project. It is advantageous to have a sufficient work area, so that the whole collection can be laid out and viewed at the same time, and for the whole duration of the refitting process. If this is not possible, trays may be used to compare batches based on a certain criterion. In order to protect the artifacts from breakage, a protective foam sheet may be laid on top of the surface area.

Once taken out of their bags, the lithics, can be sorted into groups, based on attributes such as cortex variations, color, inclusions, technological stages, or into whole pieces and broken pieces. For example, broken pieces can be split into proximal ends (those with bottoms missing), mesial parts (those broken at both ends) and distal ends (those broken at the top). The size of the break may also be taken into consideration for the order in which they are sorted. Some minimum size limit of flakes may be established for large collections or for those where there are project time constraints. It is advisable to correlate the pieces with a contour map and site grid, in order to view the lithic densities and to understand the significance of where the pieces come from. For example, it may be beneficial to separate flakes into specific groups based on the densities in their distribution.


The lithics are refitted in a systematic way. Comparison of the pieces can be quite a laborious process, as some trial and error is involved at the beginning. However, with time it is possible to recognize various characteristics (such as color, size, texture or shape) from pieces that may have come from the same core. However, it is also important to note that in some cases, features can differ dramatically between pieces within the same block (e.g., if some of the flakes had been thermally altered through heating). Once the refitting for one batch has been completed, the next group may be done in the same manner, after which time the refitter may also compare the two groups for further possible refits. All conjoinable pieces should be recorded as found and glued together using a reversible adhesive (i.e., one that may be easily removed).

Conjoining is a very lengthy process, and it is difficult to find every potential refit. It is therefore necessary to decide how much refitting is sufficient for the goals of the analysis. Once all refitting has been accomplished, it is important to look at the lithic markings to see where they came from.  Index cards can be used in order to record refit numbers and sketches may be made to document the position of lithics (i.e., whether joins are above or below other pieces). It can also be helpful to input the data onto a spreadsheet (each flake would be recorded as a separate entry and include such details as size, distance and reduction stage). Locations of the refits can then be plotted on a scaled graph in order to infer meaning from the patterns constructed.


SUMMARY

Although we don’t yet know the full potential of refitting, and many scholars are aware of the fact that it does have some limitations (for example, the recognition of discrete stages in the reduction process is not as straightforward as one would assume, and site formation processes are not entirely understood), refitting can nevertheless provide a fundamentally useful tool when viewed in the context of other pertinent information (such as microwear analysis). With careful and methodological application, refitting studies can provide us with crucial information relating to many aspects of archaeology.

ARCHAEOLOGY GLOSSARY


CORE: The basic lump source material for a stone tool.
Cortical surface or Cortex: A tough, dull-white powdery and porous coating found on the outer surface of newly exposed flint nodules. This may also include smooth weathered surfaces.
Debris or débitage: Waste material created during stone tool production.
Flake: A piece of stone material removed from a core or another flake by striking.
Knapper: Someone who works stone to create a tool by applying force to its surface, either by percussion or by pressure.
Lithics: Artifacts made of stone.
Microwear or usewear analysis: the study of the working edge of an artifact for signs of use. Patterns of wear, damage or residues may be observed via a high-powered microscope.
Palaeolithic or Paleolithic: Meaning the ‘Old Stone Age’ (between approximately 2.5 million and 20,000 years ago). It pertains to the prehistoric period from the time crude tool manufacturing activities began until the appearance of fully modern human hunting and gathering societies. This era demonstrates an evolution in human brain-size, together with a refinement in stone tool technology. 
REDUCTION PROCESS/SEQUENCE or “chaîne opératoire”: The cumulative and irreversible removal of fragments from a core during the creation of a stone tool.
