    AN OUTLINE HISTORY OF CONSERVATION IN

    ARCHAEOLOGY AND ANTHROPOLOGY AS

    PRESENTED THROUGH ITS PUBLICATIONS

    Niccolo Leo Caldararo

    ABSTRACTThe article provides a survey of the historical development of preservationpractice in archaeology and anthropology, with reference to both techniques and philosophy. Theprimary focus is placed on the evolution of a body of knowledge through the literature and therise of scientific methods and specialization. The article includes a substantial historical

    bibliography.

    1 EARLY DEVELOPMENTS IN ARCHAEOLOGICAL AND

    ANTHROPOLOGICAL CONSERVATION

    This paper will discuss briefly some of the historical origins of conservation in archaeology andanthropology; it will, however, focus mainly on archaeology. Although conservation treatmentsapplied by conservators and restorers in general to archaeological and anthropological artifactshave not developed separately from conservation efforts in anthropology and archaeology, theygenerally represent two different trends of thought and practice which have influenced each

    other.

    The earliest restorations were done in the classical workshops of craftsmen and artists of everygreat civilization. For example, Ku-Szu-Ksieh (Van Gulik, 1958) described methods of repair forpaper scrolls in fifth-century A.D. China. The transition from these origins to the modernprofessional concept of conservation is of particular interest to the field of archaeological andanthropological conservation. Nevertheless, the roots of scientific conservation were traced byGettens (1974) only to the Rome Conference of 1930, sponsored by the League of Nations.Santucci (1963), however, began his history with chemical experiments by Chaptal onrestorative methods for paper, parchment, and papyrus reported in 1787, and the 1809 report,also by Chaptal, on ancient pigments; Christoforno Marino's nineteenth-century work on the

    restoration of faded writing on parchment (Gallo, 1951); and Piaggi and Davy's experiments withunrolling papyrus from Herculaneum (Bennett 1806; Davy, 1821).

    The tragedies which befell antiquities found in Herculaneum, Pompeii, and Stabia at the hands ofrestorers certainly influenced the scholars and scientists of the period of their discovery(Winckelman, 1771).1 The desire to see objects in their original condition, unaltered byadditions, and to detect fakes led to scientific procedures. This desire, along with the need toestablish provenance of manufacture and to develop systematic criteria to resolve questions ofthe objects' materials and techniques led to the introduction of the chemical analysis of ancient

    objects first published2 by M. H. Klaproth in 1798 (Goffer, 1980).

    Analysis of excavated metals, chiefly bronzes, advanced rapidly between 1800 and 1875 withthe publication of twenty-five papers by 1850 and many more by 1875 (Caley, 1951). Onestudent of conservation history credits archaeological research with establishing the philosophy

    of preserving original creations and ending the restorative destruction of the sixteenth tonineteenth centuries (Hulmer, 1955:72). Whether this philosophy can be credited with a similarchange in attitude toward archival materials, books, maps, etc., is unclear, nevertheless theimpetus toward the preservation of such materials also appeared at this time.

    Scientific studies on the effects of gas lights on leather bindings were made by Faraday in 1843,by G. Davis in 1877, and by C. Woodward in 1888. The first attempts to apply practicalexperience and scientific knowledge in restoration were published by Bonnardot in 1846 and1858. The application of techniques from various disciplines and communication betweenscholars and scientists on preservation problems were pioneered by Cardinal Ehrle, keeper of theVatican Library and promoter of the International Conference of St. Gallo on preservation ofarchival materials in 1898 (Santucci, 1963:40).

    The St. Gallo Conference was held at the same time that the first report of the Committee on theDeterioration of Paper appeared in London. It was followed by the Archivists' Conference inDresden in 1899, the International Congress of Libraries in Paris in 1900, and the establishmentof a scientific committee for the study of the decay of leather bookbindings by the LondonSociety for the Encouragement of Arts, Manufacture and Commerce in 1900. A similarcommittee was created in Germany in 1911, and the foundation of the restoration laboratory ofthe Rome Archivio Centrale dello Stato occurred the same year.

    2 EARLY TWENTIETH-CENTURY ORGANIZATION OF THE FIELD

    Especially important were discussions and cooperative efforts which resulted from the Cairo(1937), Athens (1931), and Madrid (1934) conferences of scientists and scholars andrepresentatives of the international museums sponsored by the International Museums Office ofthe League of Nations (IMO, 1949), which established the necessity for close inter-relationsbetween excavation and museum work. Much of this work is being investigated anew today withspecial focus on ancillary problems to ensure the proper care of artifacts, such as cataloguing,documentation and reporting (cf. King, et al. in Curator, 21/1, 1980), site or field conservation,and selection of criteria for collecting and storage (McGimsey and Davis, 1977; Grosso, 1978;Adamson, 1979; Lindsay Jr., 1979). Standards for proper treatment, including documentation, inthe field and the laboratory can increase the percentage of artifacts successfully retrieved and

    susceptible to productive long-term study (Feilden, 1979:34; 1982). The need in practice forsuch proper care has been reiterated for several years by various authors (Ford, 1977; Marquardt,et al., 1977; Frere, et al., 1978; Davies, 1978; Christenson, 1980; Lindsay Jr., 1979; Bourque,Brooke, Kelly and Morris, 1980; Stanley-Price, 19843

    Of course, the recovery of artifacts was of primary importance in the early phases of the historyof archaeology. What was called excavation often resulted in not only the loss of critical data onthe relationship between the object and stratigraphy but also the mass destruction of sites by awhole scale removal as well as the loss of large numbers ofobjects by theft, inadequate

    supervision and poor recovery techniques. This was often due to a lack of understanding of therelationship between the object and its environment but more often due to the disorder inherentin much if not most archaeological work in the nineteenth century (Hole & Heizer, 1965;Wheeler, 1954). The development of conservation techniques in archaeology has seen as unevenan evolution as has the excavation report (Caldararo, 1984) and in many ways suffers the same

    vagaries in application due to lack of priority and a lack of funding.

    The Lindsay study (1979:12730) found that the care of collections was at best a secondaryconsideration in the process of archaeological collection. Storage and conservation were seldomaddressed in reports and when they were they reflected a considerable diversity of treatment. Thereport in general found a lack of commitment to care of collections and proper storage andespecially to the conservation of collections. This lack of concern, however, may be a result of alack of funding as well as access to information. In a survey of thirty-seven course offerings byanthropology departments in American colleges and universities, conservation or preservationwas mentioned in only fifteen course descriptions from ten institutions.4

    3 INITIAL WORKS

    The specifics of a history of archaeological and anthropological conservation remain vague andonly fitfully illuminated in the literature. Although some archaeologists have written notes on theconservation and restoration techniques which they applied in the field and laboratory, the greatmajority have not. Fewer still have included these notes in their reports. One of the few sourcesof such information is the Society for American Archaeology Notebook(SAA-N). This informalpublication issued from 1939 to late 1942 provided a forum for archaeologists to describe newtreatments in the field and museum lab and to ponder common problems. Museum Work,published by the American Association of Museums, Curator, and Museum News in America,and the Museums Journal in England, have provided a similar outlet for archaeologists and

    anthropologists in museum settings. In 1933 the Fogg Museum began the publication of aperiodical of a scientific approach as applied to art and archaeology, Technical Studies in theField of the Fine Arts.

    Of the publications pertaining to artifact conservation, it is remarkable to note the similarity inorganization and subjects covered they reveal on comparison. Some similarity is due to thenature of the objects studied. From Rathgen (1905) to Dowman (1970) knowledge of theenvironment, soil conditions, changes in conditions which an object would go through, and anawareness of the limitations of the available materials for treatment have been a consistentthread.

    The first two works5 detailing the use of scientific techniques applied to the restoration andconservation of artifacts appeared in Germany just before the turn of the twentieth century. Theywere produced in response to the need to preserve objects of Egyptian origin in NorthernEuropean museums. The publication by Voss, appearing in 1888, was prepared at the request ofthe German government (Rathgen, 1905, ed.:v). Rathgen's work was published in German andthen translated into English in 1905 (Otto, 1979:47). It stands out from the general literature ofconservation in that it was more of a critical summary of the work of European conservators andscientists with whom he and Voss corresponded and whose work they knew through reports inpublications and of the experiences of collectors as well. Generally, Rathgen outlined the works

    of others and criticized it in terms of his own and colleagues' work. Both books may be said tohave resulted from problems produced by the extensive collecting of artifacts in Egypt byLepsius and other German archaeologists in the nineteenth century. The work of Voss andRathgen has been carried on by German conservators publishing their results in the pages ofDerPrparator and Maltechnick-Restauro and other publications.

    In the United Kingdom, Alexander Scott published three reports in 1921, 1923, and 1926 ontreatments done in the British Museum. Lucas published a comprehensive text of hisconservation treatments in its original form in 1924, the result of his work on the artifacts fromthe Tomb of Tutankh-Amen and his earlier studies as the Director of the Egyptian ChemicalDepartment (Anon., 1924). At about the same time he set up a laboratory at the Museum ofAntiquities in Cairo. The impact of this European work on American archaeologists and museumworkers came with the publication of Douglas Leechman's [application of Lucas's and otherEuropean practitioners'] techniques and procedures to the conservation of North Americanartifacts (1931). Leechman explains in his introduction that, at the time, there were only threebooks on the subject of preservation of museum specimens that were of any use and that one ofthese was the out-of-date translation of Rathgen. He states that the three were principally

    concerned with archaeological materials, particularly those from Egypt.

    Much of Leechman's philosophy and methodological procedure6in conservation has stood thetest of time, with the exception of some vague introductory phrases in which he cautions againstchanging the appearance of an object except, in some cases, very much for the better, andpromotes cleaning to return a specimen to the condition in which its original owner or makerwould have kept it. Even if we had ethnographic information detailed enough to tell us in everycase how a typical owner might keep a particular artifact, by modern professional standardsreturning it to this state would be a questionable and subjective exercise. Artifacts are found (i.e.collected from living users or archaeologically) containing traces of food, showing wear, orpossessing examples of repairs done in aboriginal settings which provide information about the

    people, their technology, diet and the attitudes they held toward the artifacts.

    Conservators are often faced with the problem of determining what is an aboriginal repair andwhat is a repair executed by a collector or dealer. Fried (1981:22945) has discussed thisproblem in detail as it affects scholarship. We have also some to realize since Leechman's time,that cleaned and restored or conserved have further implications which can compromisethe objects conceptually (Wolf & Mibach, 1983).

    This is especially a problem with museum objects7where articles of use, practical or spiritual,may be transformed into (isolated into) objects for aesthetic contemplation only. Witharchaeological materials, we have the added problem of the possible compromise of analysis,where the potential for trace element analysis and dating can be altered or destroyed even bysimple washing and handling (Brothwell, 1965; Geidel, 1982; Loy, 1983; Janaway, 1983). Anexcellent example of the dangers involved is the case in which Colin Fink cleaned an EgyptianOld Kingdom ewer and basin by electrolytic reduction and then decided after his examination ofthe objects that the Egyptians had had a chemical method of plating antimony on copper (1934).Forbes (1950:264) pointed out after a subsequent analysis that the antimony plating was due tothe electrolytic reduction of the copper objects by Fink.

    In the 1930s the series of conferences sponsored by the International Office of Museums (IMO)

    brought together archaeologists, scientists and scholars from all over the world. At theseconferences discussions of archaeological excavation, restoration and museology, and a desire tostandardize practice led to several publications. A journal, Mouseion, published by the IMOallowed results of work to be spread to colleagues who could not meet. Another IMO publicationwhich resulted from conference discussions was the Manual on the Technique of Archaeological

    Excavations (1940). Among the members of the editorial committee which produced the Manualwas H. J. Plenderleith, then Professor of Chemistry, Royal Academy of Arts, and Keeper of theResearch Laboratory at the British Museum, London. The Manual was planned as a standardizedguide to excavation work anywhere in the world. It contained a chapter on field conservationwhich drew on the recently published works ofPlenderleith (1934), Rosenberg (1934), SanaUllah (1934)S and that earlier of Rhoussopoulos (191112), among others.

    Plenderleith published a summary of his work(1956) which he intended as a handbook orworkshop guide much like the works which had preceded it (Rathgen, Lucas, etc.). The book,revised with the help of Werner in 1971, has been of immense importance in both the generalfield of conservation and in archaeology. Their work, like that of those who preceded them, wasdirected at introducing scientific methodology into a field which had previously been dominated

    by craftsmen. Both Plenderleith's 1956 edition, and his 1971 edition produced with Werner, aremajor contributions to the field of conservation and touch on field conservation techniques. Botheditions are generally concerned with treatments of objects once they are in the museum. Somearchaeological conservators have criticised their lack of detail in certain areas, for exampleHodges (1975:37); with respect to ceramics.

    4 SCIENTIFIC METHODOLOGY AND CONSERVATION IN

    ARCHAEOLOGY AND ANTHROPOLOGY

    The first American publication relating to archaeological and anthropological conservation was

    Forrest E. Clements's article in American Antiquity in 1936 (excepting the brief instructions ofHolmes and Mason, 1902). It was basically a summary of Leechman's earlier work in the contextof Clements's own experience. It was not until Keel published his work in 1964 that Americanarchaeology had a comprehensive manual designed especially for American collections inmuseum and university storage conditions. Still, Keel, like Leechman, dealt mainly withmuseum artifacts. His work was inspired by Plenderleith's 1956 edition ofThe Conservation ofAntiquities and Works of Artto which he devotes almost the entirety of his introduction,summarizing the earlier publication.

    With the introduction of scientific methodology, emerging technology of the day was quicklyapplied to pressing problems which threatened disastrous results if unchecked (e.g. see Howie,

    1984). For example, Leechman advised the use of celluloid dissolved in acetone as a consolidantfor a wide variety of materials. He also sprayed gasoline on artifacts to fumigate them(Leechman, 1931:129, and passim). However, this new tendency toward general use of chemicaltreatments was questioned quite early by Gettens (1933:41-1), who suggested that Lucas's use ofcelluloid solution and paraffin was inappropriate for some objects.

    In the last 20 years we have seen a vast array of synthetic products utilized for conservation andrestoration. A rather informal process of introduction developed8 as the discipline ofconservation matured. Rapid aging tests were occasionally applied prior to general introduction.

    6/30

    Yet as time has passed it has become evident that the aging of these treatments in real time andthe effects of varying conditions may produce unexpected results.9 In this vein we have therecent problems upon aging developed by soluble nylon (Sease, 1981) and the effect of light onplastics and thermoplastics in particular (Lightbody and Roberts, 1954; Pappas and Winslow,1981).

    It is certain that, since the founding of the Institute of Archaeology by Sir Mortimer Wheeler in1937 at the University of London, scientific attitudes have greatly aided the archaeologist in siteretrieval of artifacts and in laboratory procedures for their preservation. This has become mostapparent in underwater and marine archaeology, where retrieval is increasingly dependent onsystems developed by conservators (Bourque, Brooke, Kelly and Morris, 1980). Recent literaturecontains examples of archaeologists who recognize the need for and utility of the expertise ofconservators (South, 1976), though Clark (1954) and Wheeler (1954) set early foundations.

    Perhaps the bulk of innovations in technology along with new materials applied toarchaeological retrieval and laboratory work occurred without the intervention of conservatorsover the last 200 years. This process was generally haphazard and makeshift, with treatments

    applied with whatever materials were handy and without prior experiment on long-term effects,which often resulted in disastrous losses (e.g. Wheeler, 1954: 168). It is obvious, however, fromthe published literature of conservation scientists, researchers of the British Museum and theInstitute of Archaeology, as well as that of archaeologists, that many innovations wereintroduced either by way of scientific experimentation and practice applied in museums orthrough collaboration of conservators, archaeologists, and consulted scientists (cf. Plenderleithand Werner, 1971 ed.; Organ, 1968; McCawley, 1977; Howie, 1984).

    The archaeologist often requires microanalysis of materials for chemical content or traceelements, etc., and has historically gone to the research scientists of the museum conservationlaboratories (as well as to university scientists) for aid (e.g. Gettens, 1933). At this point the

    scientist is engaged in archaeometry. Archaeologists have learned much about ancienttechnologies by the detailed analysis of artifacts and their components. This process of analysiswhen uncovering the materials used as well as the techniques of manufacture can involverestoration of the object (Woolley, 1934:70). (Previously, reconstruction had been done either byarchaeologists, departmental employees, graduate students, or by specialized museum craftsmencalled preparators, the Jimmy Valentines of science as Stucker (1977:201) describes theirpaleontological counterparts, who often executed the exhibition of objects.)

    5 MODERN DEVELOPMENTS AND PRACTICE

    With the application of new scientific techniques and procedures, new information can bediscovered about formerly restored artifacts (Scott, 1926: 3940; Greene, 1979). To this end theteaching of archaeological conservation at the Institute of Archaeology of London University hasbeen likened to that of a physician's education: the practitioner must make a diagnosis of anobject's condition and propose treatment (Gedye & Hodges, 1964: 847). However, given theabove context, both student and archaeologist will encounter some difficulty in acquiringinformation concerning past and present conservation treatments and procedures. Although theArt and Archaeology Technical Abstracts cross-reference published articles relating toconservation, the amount of information in print on archaeological and anthropological

    conservation is comparatively small in relation to other fields of conservation or the body ofanthropological literature.

    With the rapid increase in technological apparatus and complex analytical procedures inarchaeometry and conservation, specialist scientists have become more prevalent. As Werner

    turned more toward ethnographic conservation, especially that of fragile organic objects, anotherscientist at the Research Laboratory, Robert M. Organ, began specializing in treatment andstorage of metals and wood.10 Organ published the practical but highly technical Design forScientific Conservation of Antiquities in 1968. Garry Thomson, scientific advisor to the NationalGallery, London, came to specialize in environmental concerns in museums, (such as airconditioning and the effects of air pollution on works of art). His 1978 publication, The MuseumEnvironment, is a concise description of environmental problems, their causes and prevention.W. A. Oddy, another British Museum Research Laboratory scientist, concentrated his studies onmetals and stone: corrosion and deterioration prevention and treatment (e.g. Oddy & Hughes,1970; Oddy, 1977).

    A similar trend has developed among continental European conservation scientists. TheFrench11 had been filling the pages ofMouseion from its inception, as well as Studies inConservation(France-Lord, 1962; Weil, 1958) with detailed reports of their work, most notablyin the conservation and analysis of archaeological metals. Italian contributions ranged from siteprospecting (Lerici, 1961) to the treatment of wooden objects (Augusti, 1959) to Torraca'ssubstantial aid to the field in the application of solvents to problems in conservation (Torraca,1975). In Poland, Jedrzejewska (1962; 196364) and in Czechoslovakia, Pelikan (1964; 1966)reported on progress in the treatment of archaeological artifacts, especially metals.

    Other European scientists in collaboration have published works on specific subjects. Anexample is the work by Mhlethaler, a Swiss Scientist, Bachman, (Swedish), and Noack(German), Conservation of Waterlogged Wood and Wet Leather, published in 1973. Mhlethaler

    also produced a comprehensive text on conservation (1967), while Stambolov published a majorwork on the methods of preparation and restoration of skin objects (1969) from his Amsterdamlaboratory. Significant research and experimentation were undertaken in Scandinavia. In the areaof textile conservation, the first conservation studio conceived to operate under scholarlycontrol was organized by two Stockholm museum directors under the leadership of AgnesBranting in 1908. Here scientific research and analysis were applied to the conservation of alltypes of textiles, in cluding archaeological textiles (Geijer & Franzen, 1975:7). Excavation ofarchaeological shipwrecks such as the Wasa and a long list of other excavated wrecks byScandinavian conservators and archaeologists developed conservation techniques on a widerange of objects (Patoharju, 1975:183187;Rosenqvist, 1959). Finally, Christensen (1952;1956)made substantial advances in the conservation of water-logged wood in Denmark.

    The subject of conservation in excavation was never the subject of a comprehensive work,although Plenderleith's chapter in the IMO Manual (1940) was an early yet brief attempt. Thismay, however, reflect the youth of the field of conservation, as there have been few generallyaccepted text books produced as opposed to those available in an older discipline such asarchaeology, no less technical or complex, which has a wide selection of up-to-date basic textsproduced regularly. Dowman's Conservation in Field Archaeology, published in 1970, was asOddy (1973:44) stated, the first (work) to describe in simple form, treatments which maysafely be carried out on archaeological finds in the field. Dowman's work is an excellent

    compendium of field techniques, treatments both for rescue operations and field laboratories aswell as storage directions and therefore a partial exception to the above generalization, extendingcare into the museum or university laboratory. For Dowman, aside from being out of print andcontaining some poor science (Oddy, 1973:45), has provided a much needed focus on materials,conditions, soils and methods of treatment specifically for the archaeologist. Some of Dowman's

    deficiencies are covered in a 1984 IC-CROM publication edited by Stanley-Price (1984), butalthough it includes many references, this publication fails to address other areas such as the roleof conservation in post-excavation analysis.

    A number of archaeological textbooks contain chapters or short sections which describe in moreor less detail the authors' practices in the field and laboratory with regard to conservation (e.g.Wheeler, 1954; Brennen, 1973: 151 and 161; Robbins, 1965: 173;88). Most of these are simplyoutlines of practice or lists of suggested procedures, chemicals and apparatus. Both of Heizer'sGuides fall into this category (Heizer, 1958; Heizer and Graham, 1967). The best of these textsgive examples of procedures with lists of materials as well as some cautionary remarks andsuggested alternatives, developed in some detail, differing from the former group in the specificsprovided and the background sketched to help deter possible problems. Examples of these are

    Hume 1968 and Joukowsky, 1980. With the exception of Joukowsky, none of these provides athorough reading list or bibliography upon conservation. None presents a conservation paradigmin a manner as complete as a workbook or a descriptive narrative as does Dowman, 1970.

    A recent article by Katherine R. Singley (1981) falls between Joukowsky and Dowman indescriptive effectiveness of directives. It is an excellent outline of what should be done in thefield for the care of artifacts after excavation. Outline must be stressed, for this is a very briefwork; useful as this paper is it does not touch on ecofactual remains, which make up a large partof many collections and excavation materials.

    Rescue publications of the Department of Archaeology of the University of Southhampton,

    especially Leigh (1978), give clear directions for field work but are generally limited to packingand storage. There are also several articles by Australians on conservation. Ambrose (1968)produced a practical summary of field conditions in Australia and appropriate treatments, andMcCarthy (1970) edited a volume containing several works on a variety of problems.

    Although there are professional guidelines in the field of conservation (AIC, 1980), there is nostandard view of treatment in every case. There is a wide variation in what is regarded as theproper treatment for any particular object or whether there should be any treatment at all (Beck,1982). Plenderleith admonished in 1940 (IMO, 1940:143), that the archaeologist must not leaveobjects in the hands of the conservator and give him carte blanche. The archaeologist must havea clear understanding of what can be done in the field, with those items left in situ as well asthose recovered, and what can be treated in the museum or university laboratory. In practice, thearchaeologist should have specific objectives which will dictate the type of conservation.However, in my experience these objectives are often short-sighted with respect to the survivalof the majority of objects, and the most often described treatments are cosmetic or are soconcerned with the immediate survival of the object for analysis that long-term treatments forsurvivability cannot be assured.

    Communication between archaeologist and conservator must be an ongoing process to updatewhat works in the field and to clarify the long-term effects of all treatments including those that

    may hinder research or analysis. Research and experimentation must be facilitated for thesuccessful recovery and preservation of artifacts.

    The retrieval of fragile fragments or of impressions of objects and the detection of trace elementsor information concerning the former existence of structures or objects (Biek, 1963:6065) is the

    meridian between the role of the conservator and that of the analytical scientist. Still, with all thetechnical skill of the scientists and the increasing specialization among conservators, it is thetraining of the excavators which is of utmost importance. It is with their ability and awarenessthat the successful recovery of an object begins.

    For historical collections one may also mention Guldbeck (1972), published by the AmericanAssociation for State and Local History, Waterer's 1972 work on leather which touches onarchaeological and ethnographic materials, and Lewis's Manual for Museums (1976) whichcontains information derived from the work of the United States National Park Servicecentralized laboratories set up in the 1930s by Carl P. Russell. While most of the efforts of theselaboratories have been oriented toward storage and exhibition as it is reflected in the content ofthis volume, there has been a long tradition of preservation treatments established by Park

    Service workers. Lewis's work follows on that by Ned J. Burns (1941); both were written forcurators, to provide guidance to practical solutions for collections. The impact of Burns's work,however, is problematic as even Keel (1963) hardly mentions Burns's work and then only thatconcerning the treatment of skin. Nevertheless, Burns's work was very detailed and his audience,being the Park Service personnel under whose care were many thousands of objects, probablygave his suggestions on treatments and care a very wide application. However, with reference tothis skin material, the work of Burns and that of Waterer mentioned above are of less value toarchaeologists and anthropologists than the comprehensive work ofReed (1972).

    Rowe (1953), in his summary of technical aids in anthropology mentions Rathgen (1905),Rosenberg (1917), Plenderleith (1934) and Leechman (1931) as the comprehensive texts in

    restoration. He mentions Lucas (1924) for chemical identification and analysis and Gettens(1950) and Fink (1933) for specific applications. The appearance of an article such as that byVelich (1965) in a journal of the professional caliber ofCuratorperhaps belies the actual effectof much of this work described above. While Velich's description of his treatments of skinartifacts of American Indians were not entirely unacceptable in the context of the time, they areextremely pedestrian in retrospect and must indicate a lack of familiarity with earlier publishedwork, most specifically in his restorative efforts with ballpoint pen.

    6 SPECIFIC GEOGRAPHIC DEVELOPMENTS

    To return to Canadian archaeology, passed over after the discussion of Leechman's earlycontribution, it has had a rapid and intense involvement with conservation. William Todd, ChiefConservator of the Royal Ontario Museum until his death in 1963, published several papers onthe conservation of materials, his subjects ranging from bone preservation (1941) to restorationof Chinese grave figurines (1952) to preservation research in Chinese bronzes. In 1966 theBritish Columbian Provincial Museum recruited its first conservator, who was the only one westof Toronto for the next four years (Ward, 1978:9). Care of collections prior to this date had beenexecuted by other staff specialists. In 1970 the first course in conservation was established at theUniversity of Victoria, entitled Conservation of Antiquities, as a course for curators. The

    Canadian Conservation Institute (CCI) was originally conceived in 1972 at Ottawa and twocenters were established in 1974, the Pacific Regional Center and an Atlantic Regional Center,followed by a small facility in Quebec in 1977, with Erika Schaffer the principal scientistinvolved in the preservation research program for archaeological and anthropological materialsof the CCI. Her work as a conservation scientist both in identifying materials of composite

    artifacts and designing treatment procedures has added considerably to the development of anorganized methodology (1971, 1974, 1976, 1981), as has the work of another Canadian scientist,Mary-Lou Florian (1976, 1977, 1978, 1981). The development in Canada of the application ofscientific techniques in archaeological conservation has been rapid especially in wet site andfrozen site problems (Hett, 1978). Mac-Donald presents a concise outline of the development ofwet site archaeology in Europe and North America in his 1977 article.

    While conservation in Australia dates well into the last century with the establishment of ageneral lab in New South Wales (Lloyd, 1981), conservation work there has benefited fromconservators with a broad range of skills and interests from fine arts to archaeology. Oneexample is Boustead, who treated a wide range of ethnographic objects (Boustead, 1960; 1966).Australian archaeologists have written several articles on both field practice and museum work

    (e.g. Macintosh, 1968; McCarthy, 1970). Their publications in general reflect a closerelationship with European (especially British) conservation efforts as well as localexperimentation. Boustead, like many Australian conservators, learned his trade as an apprenticeand later augmented his skills by tours of study in Europe, mainly England. Many Australiancultural institutions provided training for other surrounding nations through funds provided bythe Commonwealth; these ranged from India to Pacific Island nations.

    The tradition of the independent efforts of museum preparators in setting up conservationfacilities is seen in the creation of the first conservation lab in New Zealand in 1953 (Thompson,1985). The Pacific Regional Center, at its Honolulu facility in Hawaii, has trained local residentsand treated regional collections from the Pacific Islands, as well as sent conservators out on

    location (Lee, 1978). The Pacific Regional Center resulted from a study undertaken by Werner in1973 and sponsored by the Bishop Museum to determine the needs of Pacific Region museuminstitutions which led to the establishment of the Pacific Center in 1974 (UNESCO, 1980).

    The Soviets and East Europeans developed parallel technology in the application of materialsand have conducted extensive research and experimentation with synthetics (Nogid & Rozdnyak,1965; Tomashevich, 1969). Grabar published a restoration manual in 1960 which presents amixture of synthetic (new) and old traditional methods with some criticism of the poor agingresults of some particular traditional methods (Kovostovetz and Thomson, 1963). The same canbe said of the Japanese (Higuchi and Aoki, 1976; Aoki, 1985).

    Concerning the Japanese, Yamasaki (1957:83) places the first technical conservation work in1919 with the government-formed committee on the wall paintings of the Horyuji temple atNara. An attempt to stabilize the peeling paint was undertaken using natural resins (copal), butthe trial in a small area failed to produce satisfactory results and was discontinued. In 1933Professor S. Taki of Tokyo University organized a small study group of art historians, physicists,chemists, biologists and architects. Discussions of methods of repair and conservation of artobjects and studies of scientific and new methods of repair compared to traditional methods wereundertaken. In 1947 the group was organized into the Association of Scientific Research inAntiques with Professor Y. Shibata as president. A journal was established by this group,

    Scientific Papers on Japanese Antiques and Art Crafts, the first issue appearing in 1951,although today the primary Japanese publication for conservation is Science for Conservation.

    In addition to these efforts, the Institute of Art Research in Tokyo, founded in 1930, wasreorganized in 1952 as the Tokyo National Research Institute of Cultural Properties, with a

    Department of Conservation added to it (Yamasaki, 1957:83). This Department of Conservationwas housed in the Tokyo National Museum and was concerned mainly with the conservation ofpaintings and sculptures in temples and museums. This Department of Conservation was laterchanged to the Department of Conservation Science and a Department of RestorationTechniques was added (Ito, 1979:xi).

    In 1902 the Archaeological Survey of India proposed a chemical branch, which was establishedin 1917 when a laboratory was set up in the Indian Museum in Calcutta. Later the laboratory wastransferred to Dehre Dun and work organized on methods established at the British MuseumLaboratory (Swarnakamal, 1975:25). A laboratory was set up at the National Museum, NewDelhi, in 1958 as a central major research facility (Gairola, 1960; Agrawal, 1963). T. R. Gairola,Chemist, National Museum of India, New Delhi, published a Handbook of ChemicalConservation in 1960 which offered recommendations for treatments of all types of objectsfound in Indian museums; the handbook is organized by physical composition (organic, metalsand siliceous). Basically it is a manual for museum workers, written for the post-graduatestudents of the Department of Museology of the University of Baroda, although it does containexamples of treatments of archaeological materials. Gairola draws heavily from the Europeanand American literature and his own extensive experience.

    Shortly after the establishment of a central conservation laboratory at the Baroda Museum for theState of Gujarat, Swarnakamal published a book, Protection and Conservation of MuseumCollections (1975), which is entirely concerned with treatments in museums. Individualtreatments of archaeological materials were from time to time published in several Indian

    journals including Journal of Indian Museums, and Ancient India. Other Indian conservationlaboratories were established at Lucknow, and at the National Museum, New Delhi. In 1977, O.P. Agrawal, who studied under Gairola as well as at the Instituto Centrale del Restauro in Rome,published a book on the Care and Preservation of Museum Objects, one of a series of books onconservation in Indian museums and in Southeast Asia; it includes a bibliography onconservation in India. Agrawal is the Director of the National Research Laboratory forConservation of Cultural Property, Lucknow, and has edited a journal, Conservation of CulturalProperty in India, from 1967 to the present. He produced several studies on the conservationneeds of Asian nations as well as edited several books, including Conservation in the Tropics(1973), Documentation in Museums (1974) and The Small Museum (1975). His survey ofconservation needs and techniques of Southeast Asian cultural properties, originally published inMuseum in 1975 as Conservation in South and Southeast Asia, was expanded and republished byButterworths in 1984.

    In Africa, archaeological and anthropological conservation has been derived in most part fromEuropean efforts, particularly British and French. A manual for conservation of collections ofMiddle African museums was produced by Kennedy in 1959 and contains the usualorganization, beginning with the effects of climate on objects, the agents of deterioration(insects, microorganisms, etc.) and then an overview of restoration techniques. A substantialnumber of local institutions have developed techniques for the extraction and cleaning of fossil

    materials, derived from traditional methods in paleontology, especially in Kenya and SouthAfrica. For the purposes of this paper, conservation efforts in paleoanthropology will beconsidered a separate literature and will not be covered.

    Through the agency of international organizations several conservation scientists were able to

    travel widely sharing skills and initiating programs. One of these was Paul Coremans (1968:135139; Tahk, 1984:1625), whose energies and interests carried him from his base in Brussels atthe Institut Royal du Patrimoine Artistique to sites in Indonesia, Burma, Thailand, Iran, Iraq,Peru, Mexico, and the United States of America.

    F. Mairinger12 of the Insitut fr Farbenlehre und Farbenchemie, Academie der BildendenKnste, Vienna, recently visited China for the purpose of investigating analytical practice inconservation. He found their level of expertise based on pre-World War II technology, althoughthey apparently are being influenced by Japanese experience and new Western methods.13

    UNESCO, through its Museums and Monuments series, published a volume prepared by theInternational Centre for the study of the Preservation and Restoration of Cultural Property

    (Rome), now ICCROM, The Conservation of Cultural Property (1968). This was of specialinterest as it was written with reference to problems related to tropical conditions and situationswith few technical resources. Articles were prepared by such workers as Daifuku from Bangkokand Andrade from Brazil. Other shorter documents have resulted from special seminars orconferences supported by UNESCO and ICOM. Among these are the reports written by Werneron the Conservation of Ethnographical Collections (1968) and Conservation of CulturalMaterials in Humid Climates (Regional Seminar) published by the Australian NationalConference for UNESCO in 1980.

    In Argentina Tellchea (1981) produced a comprehensive text, Enciclopedia de la Conservacion yRestauracion, particularly designed for cultural materials found in South America and written for

    a wide audience, from craftsmen to conservators, as well as diverse environmental settings.

    7 CONCLUSIONS

    The development of conservation practice in archaeology and anthropology proceeded on asomewhat haphazard basis with European publications influencing American writers in a slowand uneven manner. The actual effect of these publications is questionable as treatments arescarcely mentioned in archaeological reports. In general, as Howie's results (1984) indicate forthe field of paleontology and as seems consistent from the bibliographic material in this paper,methods and materials are easily introduced but resist rejection. Publication of new data on

    materials, rejection/repudiation of inferior techniques, and the introduction of new methods areslow to reach the majority of practitioners.

    What this survey has shown is that there is a great need for conservators to offer courses inuniversity anthropology departments and to offer reviews of general anthropology andarchaeology texts, site reports and survey materials in order to expose archaeologists andanthropologists and their students to new trends in conservation. These reviews must be offeredto journals in the field of anthropology and archaeology as well as appearing as presentations innational and regional conferences. A related problem is the lack of general texts in conservation

    and especially archaeological conservation.

    Specialization in analytical and recovery techniques will most likely continue to benefit studentsof archaeometry rather than those minoring in conservation in university departments ofanthropology. The largest number of university positions call for individuals who can still teach

    in several general survey and subject areas while pursuing specialized research, but we can hopethat the trend of double masters (so frequently seen in England) of anthropologists with diplomasin conservation will increase.

    The trend toward specialization in conservation is becoming an increasing reality in thegraduation of conservation students from the various programs (NIC, 1984). This trend and theincreasing number of retiring general practitioners in conservation will deny to the field thepublication of generalized texts so prevalent in other fields and especially needed here tointroduce archaeologists and their students to the field. The composition of such texts differsfundamentally from collections of articles written by different specialists, in that the experiencedoverview is drawn from years of study and experiment seasoned with examples of trial and error

    so necessary to learning. Such texts are the foundation of any discipline and, as the yearly swarmof introductory texts in every field proves, a necessary means of updating and focusing any bodyof organized knowledge.

    The specter of so many experienced and older practitioners leaving the field by retirementwithout publishing summaries of their experience or outlines of their work in textbook formbrings to the mind the plea of the 1923 Committee on Restoration and Preservation of Painting,Drawing and Prints (Museums J., 1923:118): it does seem necessary to issue a reminder thatthe absence of any official record of the measure of success or failure is an effectual barrier tothe progress of knowledge upon the subject in question. The publication of volume I of HermanKhn's Conservation and Restoration of Works of Art and Antiquities by Butterworths (1986) isan exception which hopefully will become a trend.

    NOTES

    1. Brommelle (1956) describes a similar reaction to the early attempts at cleaning paintings inthe National Gallery in England that led to the Select Committee Reports of 1850 and 1853.

    2. Klaproth's paper was actually read publicly in 1795 but not published until two years later.Most authors, however, give Klaproth credit for the first publication even though a chemistnamed Pearson published a paper in 1796 and read in the same year (Caley, 1951:64; 1949:242).

    3. Osgood's (1979) observations of storage conditions and conservation practice in American andCanadian museums present considerable evidence supporting this view. His recommendationsfor conservation treatments are out of date at best and are, at worst, examples of the need forscientific, standardized conservation practice.

    5. Although the Bonnardot books among others (Brommelle, 1956; Ruhemann, 1968) wereearlier, the presentations of Rathgen and Voss were the first systematic applications of scientifictechniques (trans. note, Eng. ed. Rathgen, 1905). Rathgen's 1905 publication was most oftenquoted and referenced, though this two-volume Handbcher published between 1915 and 1924is referenced by both Rowe (1953) and Heizer & Graham (1967).

    6. Although certain segments of his paper have earned criticism for the fragmented treatmentpresented (Plenderleith, 1932: 508), many items were only described in outline.

    7. This concept was argued by Pettenkofer (1870) with regard to paintings and was extended byDoerner (1934) to other art objects.

    8. The National Conservation Advisory Council submitted a report, Proposal for a NationalInstitute for the Conservation of Cultural Property (1982), which outlined a formal process andaddressed the problems of the present situation; see pp. 2627. Howie's recent research (1984)has shown the rapid application of new synthetic products and the slow rejection of materialsfound to be inappropriate for treatment. Another aspect of this is the reapplication of oldtechniques once rejected and reintroduced at a later date, such as in bleaching in paperconservation. A table such as Howie's could be constructed for bleaching showing the use of thehypochlorites; the use of hydrogen peroxide (Scott, 1926), its rejection (Hey, 1977) andreintroduction (Walsh, 1986); or the use of sugar in the stabilization of wood, its fall from favorand reintroduction (Parrent, 1985). Werner outlines the introduction of some synthetic materialsin a 1968 report and later in a 1981 article.

    9. Greathouse and Wessel's Deterioration of Materials (1954) provides data on the complexitiesof the process of deterioration of natural and synthetic materials, as well as descriptions of thedisastrous results of material failing, when testing could not foresee the effects of varyingclimates and environments in combination with long-term oxidation, radiation and other factors.

    10. Organ (personal communication, 1985) objects to this generalization which basically reflectspublished reports of work. As Organ points out, the demands of one's professional duties oftenforced practitioners to treat a wide variety of objects, yet a particular worker's publications mayonly reflect the most interesting challenges, a special interest, or only those specific treatmentswhich he or she felt proposed the most significant contributions to the field. In the case ofarchaeology Organ's comments are even more appropriate: as the range of objects in mostarchaeological collections has demanded generalization in the practice of those who werecharged with their care, as well as the composite nature of most archaeological andanthropological objects; this has been especially true of work on archaeological excavations.Thesituation has been changing, but specialization has had a much greater effect in other areas of thefield of conservation, especially in paper and paintings. One particular example of the situationOrgan mentions is that of George Stout, whose publications were generally in the area ofConservation of Fine Arts, mainly paintings, but whose influence and other unpublishedcontributions were considerable in other areas of conservation (Plenderleith, 1987). Also, hispublished works were often of such breadth that they could be applied to numerous problemsand lines of inquiry in conservation as well as archaeology (e.g. the text on painting materials hepublished with Gettens in 1942).
