Story, Page 11 THE CAUSES OF WAR By Jonathan Haas Curator of New World Archaeology and Vice President, Collections & Research come to the topic of the anthropology of war from the perspective of an archae- ologist. You are forgiven for wondering what an archaeologist could possibly have to say about war — the Trojan War perhaps, but warfare in general? Archaeol- ogy deals with ancient people, long dead, bro- ken stones and dusty bones. There are two faces to archaeology, how- ever, and two different kinds of goals guiding the direction of archaeological research. The first looks at the his- tories of peoples from the near and distant past. Using artifacts and other material remains of past human behav- ior, archaeologists attempt to fill in the historical detail of different people, places, and times. This is the traditional realm of archaeology, and what we most often associate with the discipline. But an alterna- tive goal for archae- ology is to go beyond the ancient past and use the archaeolog- ical record to help explain patterns of human behavior in the present as well as in the past. It is in this realm of explanation that archaeology can contribute most to our understanding of intercultural and interethnic violence in the modern world. es ee Ethnic and cultural differences are a necessary and sometimes artificial prerequisite of warfare. The causes of warfare are not ethnic differences, however, but economic and demographic conditions at a given moment in time. to gain a new perspective over very long peri- ods of time on the relationship between warfare and the rise of ethnic differences. Archaeology also allows us to see that warfare between dif- ferent ethnic groups in relatively simple soci- eties is an irregular phenomenon, subject to environmental influences. I would offer two different insights into warfare drawn from archaeological research. First, ethnic and cultural differences are a nec- essary and sometimes artificial prerequisite of warfare. What I mean by “artificial” here is that if ethnic differences don’t exist before a war, they are sometimes made up to justify a war. Second, the causes of warfare are not to be found in ethnic dif- ferences, but in the economic and demo- graphic conditions at a given time. Less than Human During the recent Persian Gulf crisis, a segment of “All Things Considered” on National Public Radio had a discus- sion of Saddam Hus- sein’s policy of using foreign nationals as “shields” to protect critical facilities. President Bush denounced this tactic by asserting that even Hitler did not do such a dastardly thing in World War II. Curious as to how common such a practice might have been in the past, the NPR commentator con- tacted Shelby Foote, the In the Persian Gulf war, George Bush set the stage for the assault on Iraq by establishing the inhumanity of the Iraqi enemy. So too we see the pattern of cultural differentiation emerge as a precursor to the beginnings of warfare in the prehistoric past. Looking at the historical trajectory of the Anasazi Indians, the archaeological record shows that the origins of warfare go hand in hand with the evolution of cultural or ethnic differences. Actually the separation of different and distinct ethnic groups starts first, and it is only after it is fully developed that one of the conditions for conflict appears to have been met. The full evolution of ethnic differences takes several hundred years. In the first century A.D., the entire Anasazi region is culturally similar. Everybody basically looks alike, with the same kinds of settlements, similar types of pottery, arrowheads, burials, houses, etc. By A.D. 1000 this pattern is in the midst of a transformation, with the emergence of clear regional and subregional differences. Pottery is decorated with different designs, and houses are different from one area to another, for example. Over the course of the next two cen- turies this pattern continued to develop and quite distinct culture groups appear in the archaeological record. Groups such as the Mesa Verde and Kayenta Anasazi are distinguished by pottery designs, tool types, housing styles, burial practices, religious structures, and rock art. It is centuries after this pattern of culturally distinct groups becomes well established that a pattern of warfare first appears. (Continued on page 10) folksy historical consultant on the Civil War miniseries. Foote commented that indeed the Union had used very similar tactics when they took prominent Southern civilians and placed them on The two ceramic vessels shown here illus- trate the divergence in style and form that emerged after A.D. 1000 in the Anasazi region. The pot below is a Kayenta black- on-white “seed” jar used for storage, while the vessel at left is a classic Mesa Verde black-on-white mug, used for eating. My own research is on the origins and evo- lution of warfare among the native people of the southwestern United States in the centuries prior to the arrival of the first Europeans in 1540. This research has produced a specific historical record of the beginnings of warfare in the 13th century A.D. among the Anasazi living in what is now the Four Corners region of Ari- zona, New Mexico, Colorado, and Utah. “Anasazi” is a term taken from the Navajo lan- guage meaning “ancient ones.” It is generally used to refer to the prehistoric peoples who built the classic pueblo and cliff dwellings that we so commonly associate with the Southwest. My colleagues and I have attempted to trace the native patterns of war and peace for the next several hundred years through the peri- od of first contact with early Spanish explorers and the following century of Spanish colonial- ism. Beyond this historical detail, however, the research offers some insights into the type of warfare we are likely to find in tribal societies in the present as well as the past. Specifically, through the archaeological record, we are able supply trains in an effort to prevent Rebels from attacking the trains. (This effort was futile, it turned out.) The Union forces only took this measure, however, after the Rebels had killed prisoners of war simply because it was too much trouble to keep them. Foote’s interpretation of these phenomena is interesting in the present context. He argued that in the heat of war, even between culturally very similar people, once one side committed a perceived inhumane act, the door was open for the other side to respond in an equally inhu- mane way. Acts of war become justifiable if the opponent is seen as being inhumane and thus somehow less than human. In the Civil War, where there were no real ethnic differences between the North and the South, difference was created to justify killing. Paul McGrath VITAL FUNCTIONS By Willard L. Boyd President, Field Museum he Field Museum is a little city in itself, open every day of the year except three. Like any town with lots of traffic, it requires basic ser- vices that are provided by a corps of dedicated staff members working largely out of sight. But members of the Museum ought to be aware of how vital these functions are. Our housekeeping staff, consisting of 33 people, works two shifts to keep the space clean and attractive for visitors of all sorts, whether members of the general public or scholars from around the world. We contract with Service Master, a commercial cleaning firm, to maintain up-to-date training programs to achieve the highest standards of cleanliness. We take great pride in the fact that in any pub- lic space one is likely to visit, ours is among the very cleanest. Along with housekeeping there is the regu- lar paint-up, fix-up that needs to go on in any- body’s place of business or home. We have a group of 14 engineers as well as seven painters and carpenters who on a daily basis have to repair leaks, maintain the boilers and air condi- tioning equipment — and change light bulbs. Indeed, there are some 15,000 to 20,000 light bulbs in the Field Museum. The Field Museum consists of nearly one million square feet, of which 400,000 square feet is open to the public and 400,000 has limit- ed access because it houses research and collec- tions. Heating and cooling this space is both a major engineering feat and a major demand on our financial resources. Through a_conserva- tion program over the past 15 years, our opera- tions manager, Norman Radtke, has achieved wonders by reducing consumption to hold costs at the 1980 level. For example, when the Northwest Coast Indian Hall and Inuit exhibit was opened in 1981, no special cooling or heat- ing equipment was provided; rather, oscillating ceiling fans draw the air in from other parts of the Museum and thereby cool and heat that exhibit. Special lighting to conserve energy was also installed. The heart of the Museum is of course its collections, and those collections must be secure. Our security staff of 42 works around the clock to keep the building protected. On the one hand we are obviously providing security from theft — but comparable demand has to be placed on security from fire and water damage. Then of course there is the question of pay- ing the bills, which are many. This is the responsibility of the finance, accounting, cashier, and payroll departments. It is their responsibility not only to make timely payment but also to apply the funds in the proper legal and business manner to meet the standards of the Internal Revenue Service and the various agencies that monitor our use of funds. The purchasing department has the responsibility for finding a myriad of goods ranging from lumber, paint, and glass to stainless steel labo- ratory equipment, at the same time meeting various kinds of government regulations and institutional objectives such as including minority and women’s business enterprises. And if you ever come to a program put on by the Education Department, it is amplified by our audio-visual department, three people who work seven days a week to provide the best in public-programs support for our visitors. Our own print shop, which is now 60 years old, pro- vides most of the stationery, forms, and other printed paper that the Museum, like every large organization, requires. The Museum staff receives mail from all over the world; it is all handled by three mail- room employes who also mail out thousands of communications each month. Both incoming and outgoing mail often includes scientific specimens of the rarest form. We are proud of the fact that all of the ser- vices which are essential to making this Muse- um great are carried on without undue notice by the public, which shows how efficiently and effectively these varied staff members serve you, the visitor. From time to time, Jn the Field will intro- duce you to some of the men and women who make up the Museum services staff. CRANE, INGER NAMED TO MacARTHUR CHAIRS wo Field Museum scientists have been named to chairs established under a major grant from the John D. and Catherine T. MacArthur Foundation. They will be honored at the annual meeting of the Founders’ Council April 8. Jonathan Haas, Vice President for Collec- tions and Research, announced the appoint- ments of Peter R. Crane as MacArthur Curator of pale- obotany and of Robert F. Inger as MacArthur Curator of amphibians and reptiles. Crane is chairman of the Geology Department, and Inger is past chairman of the Zoology Department. Peter Crane’s recent research has focused on the origins of the flowering plants in the mid-Cretaceous period some 100 million years ago. Robert Inger has been working on the evolu- tion of amphibians and rep- tiles in Borneo and the effects of logging on those : faunal communities. The Founders’ Council is composed of individuals who contribute $1,500 or more annually or who make other major gifts sup- porting the Museum as an international center for scientific research and education.

NEW CURATOR IN FISHES ark Westneat has been appointed assistant curator in the division of fishes, Department of Zoology. His principal research interests are the evolutionary relationships among the 600 species of wrass- es, and the “functional morphology” of feeding and swimming in fishes. The latter study is an effort to document — using high-speed film and video — the mechanisms of force transfer from muscle through connective tissue to skeleton in three families of living fishes. Interpretation of data involves comparative anatomy, theory from mechanical engineering, and new image- and motion-analysis techniques. Westneat also seeks to clarify the patterns of evolution in these functional systems. Westneat received his Ph.D. from Duke University in 1990.

UPSTAIRS, DOWNSTAIRS TOMB ROBBING 101 By Steve Crescenzo lorence Selko is explaining the mummification process that ancient Egyptians used to preserve their dead to a group of sixth graders from Rockford who all look like they would rather be somewhere else. However, as Selko gets to the part when the brain is pulled out of the skull with a hook — “I know it’s right before lunch . . . sorry,” she apologizes — the children start to perk up. She keeps the momentum rolling, asking the class, “Who thinks they would be a good robber?” A dozen kids raise their hands, and then listen intently as Selko describes how tomb robbers tunneled their way into a pyramid to steal the valuable jewels contained within. Now that she has their attention, she’s ready to start her tour of the “Inside Ancient Egypt” exhibit. So are the kids. Selko, who will be 71 in April, has been leading tours as an Education Department vol- unteer for almost eleven years. She works with people of all ages, including college classes and adult tour groups, and over the years has learned to adapt her style of teaching to suit whatever group she is trying to reach. “You have to do different things to different people to get them to open up,” she explains. PROGRAM ON FORGERY IN ETHNOGRAPHIC ART he Collections Committee, the Muse- um’s newest special-interest support group, meets March 25 for “Facts about Fakes,” a presentation on forgery in ethnographic art by Bennet Bronson, chairman of the Department of Anthropology, with Phillip Lewis, curator of primitive art and Melanesian anthropology. A reception in the Founders’ Room begins at 5:30 p.m. and the program starts at 6 p.m. For information, call Heidi Bloom at (312) 322-8874. The Collections Committee, chaired by Mr. and Mrs. James J. Glasser, was organized to increase awareness about the Museum’s unparalleled ethnographic collections and to provide a forum for the exchange of ideas and information on ethnographic collections and collecting. The group plans to host a variety of edu- cational activities and programs including pre- sentations by Field Museum scholars, behind- the-scenes tours of Field Museum collections, conservation lectures and workshops, and vis- its to private collections of Chicago-area col- lectors. Although she is involved in several dif- ferent programs, rang- ing from a “Sugar and Spice” program in the botany exhibit to a pre- sentation on the masks of the Northwest Coast Indians, Selko says the Ancient Egypt tour is her favorite — and her forte. “I’ve taken all of Frank Yurco’s classes, and I always go back to him whenever I have any questions.” Yurco is the Museum’s Egyp- tology consultant. It’s that in-depth knowledge of her subject matter that makes Selko’s tours special events. Visitors under her care share in the wealth of her knowledge, learning rather than merely looking as she deci- phers hieroglyphics and points out the canopic jars that are used to hold the organs of corpses about to be mummified. Selko first volunteered during the “Gold of El Dorado” and “Great Bronze Age of China” exhibits in 1980s and plans to continue volun- teering “as long as I am able to get around.” “T’m retired,” she explains when asked why she likes to be so involved with the volun- teer program, “and life really doesn’t mean all that much if you have nothing to do. Volunteer- ing gives me a real feeling of satisfaction that I am helping people, and besides that, I love Egypt, so it’s fun and interesting for me as well.” WALKING TOUR OF SWITZERLAND hether you’re a casu- al walker or an expe- rienced hiker, there’s something special for you in an unusual Field Museum Walk- ing Tour of Switzerland June 4-17. Escorted by two resi- dents of Engelberg, Jacqueline and Arne Tofte, the daily walks will range from five to ten miles with adequate rest stops. Four locations will be visited including Engelberg, Zermatt, Zuoz, and Appenzell. Outdoor activities take place at an altitude of more than 4,000 feet, with cable cars or mountain railroads used to reach higher elevations. The Toftes have been host- ing similar walking tours for the past twelve years, and their extensive knowledge of the lesser-known trails, customs, and specialties of the region promise to make this tour one of the most exciting ever presented to Museum members. Along the way, charming area hotels and excellent local cuisine will add much to the enjoyment of this unusual tour. Cost of the tour is $3,475, including air- fare from Chicago, all accommodations, and most meals. Members who are thinking about a Fall trip might consider the Museum’s three-week tour of Botswana and Zimbabwe, September 17 — October 4. Highlights include the Larvon Bird Garden in Harare, with some 430 species on the wing; Mana Pools National Park on the Zambezi River; Victoria Falls; the Okavango Delta; and Chobe National Park.

Through the use of hands-on, interactive learning tools, visitors can discover how the “plates” that carry the continents and oceans are constantly mov- ing, and how that movement affects the world we live in. The theory of plate tectonics, which creat- ed one of the most profound revo- lutions in scientific history, states that heat from the Earth’s interior propels the surface “plates” into constant motion. These movements have played a key role in all phases of the Earth’s his- tory, including development of the atmosphere, the evolution and diversi- y §= fication of life, moun- tain building and ocean basin formation, and past and present earthquake and vol- cano activity. Plate tectonics also affects global climate. Plate movements over the past 50 million years changed sea levels and oceanic and atmospher- WHERE THE WORLD ic circulation, ultimately resulting in the forma- tion of polar ice caps and recurrent “ice ages.” These changes take on special meaning with current concerns about global warming and the Greenhouse Effect. Visitors to “Moving Earth” will get an up- close view of how plate tectonics works as they walk into a cutaway six-foot globe and experi- ence first-hand the Earth’s layers and the con- vection of heat from the core to the surface. They will also be able to touch the layers of the earth in a three-foot cross-section of a globe, and see how plates actually move on the earth’s surface by sliding around the plates on a small interactive globe. The exhibit also includes an animated video that traces the history of plate movements for the past 600 million years. Later components of “Moving Earth” will be devoted to “Earth Processes” and “Global Climate.” The exhibit is located at the north end of the second floor, where it will eventually be joined by a major new exhibit titled “Life Over Time” that will explore the evolution of life on earth. >, NatureWorks .

There are also plans to renovate and move the Maori meeting house from the ground floor fo the space vacated by the apatosaur in the In November 1992, “Exploring American Wilderness” will open in the Rice Wing (first floor west) where “Mammals of America’ used to be. This part of the animal kingdom exhibits will also include a zoology resource center in Rice Hall where “Mammals of Africa” used to be — right next to the current “Into the Wild” exhibits. A new tultidisciplinary exhibit on Africa, scheduled to open in November 1993, will go into the remaining first floor west space. On the second floor, “Life Over Time” will be installed in the northeast halls, using two currently empty halls as well as the north half of “Plants of the World.” To make room, “Plants of the World” has been combined with the “Useful Plants” exhibit to form a single large botany exhibit in the southeast halls of the second floor. __.

Center left: The Southwest today is in a cycle similar to that of the 13th cen- tury, with most annual precipitation coming in the form of heavy summer thundershowers.

Bottom right: Hard to conceive, but there was a signifi- cant prehistoric set- tlement atop this steep mesa.

WAR... (Continued from page 1) Fifty years of war In the middle of the 13th century, the peo- ple of the region suffered prolonged environ- mental stress — cyclical droughts, erosion of arable land, and growing malnutrition. It is only under these circumstances that we see indica- tions of warfare breaking out among the differ- ent culture groups of the Anasazi. We find burned houses, wrecked villages, headless skeletons, and skeletonless heads. The people took extraordinary measures to move their homes into protected and highly defensible locations, and defensive communication net- works link together all of the villages in a wide region. Although we do not have good evi- dence of the intensity or frequency of warfare at this time, the archaeological data do provide a record of serious, endemic warfare all across the northern Southwest for a period of about 50 years, after which the entire region was abandoned. Note that conflict arose only after the development of discrete, culturally different groups. Prior to this cultural differentiation, there are no signs of warfare in the Anasazi heartland for centuries, The various subgroups of the Anasazi, these early ethnic groups, were at peace with one another. They coexisted side by side for more than 200 years with absolutely no signs of conflict between them. It is long after the cultural foundations have been laid for distinguishing “us” from “them” that raiding, killing, and burning appear as a complex response to environmental stress. While cultural or ethnic differences are found as a precondition of warfare, they should not be interpreted as a sufficient condition or cause. For this we must look elsewhere. Ethnic violence Again returning to the modern world, we read and hear every day of the breakup of east- ern Europe and the reemergence of violence between different ethnic groups. The inference is often made in the press that the violent ten- sion has always been there but it has been sup- pressed by the power of the communist state. With the fall of communism, the inherent eth- nic hatreds bubble to the surface and the vio- lence of Yugoslavia, or Armenia, or Azerbaijan results, But is the cause of this violence simply ethnic difference? Are the Croats and Serbs killing each other because of differences in their religion and linguistic backgrounds? Or are such ethnic differences a convenient divid- ing line in countries facing economic collapse and chaos? The silent and remote archaeologi- cal record from the American Southwest sug- gests that economics and not ethnicity is the driving engine behind the warfare we see aris- ing in eastern Europe and recurring elsewhere around the world. With the Kayenta Anasazi, the original pat- tern of warfare arose only after 150 years of progressively deteriorating environment. We have a detailed environmental record for this region carefully reconstructed from tree rings, geological analysis of soils, and pollen sam- ples. This record of the centuries prior to the onset of conflict shows that beginning about A.D. 1100, the environment began to change from one highly favorable to farming, to one not so favorable. Prior to 1100, there was lots of annual precipitation, most coming in winter snows, no signs of droughts, generally a high water table, and rich, built-up soils. The human remains from this period reflect a population that was relatively healthy, with good nutrition and few diseases related to diet. Population densities were relatively low, with abundant land for the number of people in the region. After 1100, while the population continued to grow, the precipitation pattern changed, with less overall moisture and a shift to more sum- mer-dominant rainfall. The significance of summer-dominant rainfall in the Southwest is that the water comes in the form of thunder- showers that drop a great deal of rain in a very short period of time. The water then does not soak into the ground, but washes away, carry- ing soil with it. Erosion, therefore, increases at the same time. So there is not only less annual precipitation, but it is coming in a form that is not as useful to farmers, and it is eroding away their arable land. This pattern then intensified over the next 200 years, and the ancient Anasazi farmers found themselves faced with an increasingly hostile environment at a time of maximum population density in the region. Archaeologically, we see signs of growing mal- nutrition, declining average age at death, and a significant increase in the deaths of small chil- dren and infants. Us vs. them It is in response to such severe environ- mental and demographic stress that warfare first arises among the Anasazi. There were too many people, their crops were failing, their land was being washed away, and their children were dying of malnutrition. Their adaptive strategies, so successful in the past, were no longer adequate to cope with a changed envi- ronment. Peaceful relations with neighboring groups, once a source of security in times of occasional stress, no longer could be relied upon. “Us” and “them” together in a world of relative bounty, became “us” versus “them” in a world of stress and shortage. I should also point out here that residents of this region had faced similar environmental problems in earlier centuries but had not resort- ed to conflict with their neighbors. The cultural circumstances, however, had changed. Popula- tion was greater, and the emerging ethnic dif- ferences served as a natural line of cleavage within the region as a whole. Thus, warfare, the killing of one’s fellow human beings, became an option in the range of responses of the Anasazi only after the cultural homogeneity had broken down and diverse ethnic or tribal groups had appeared. Returning to the archaeological record of the Anasazi, a complex set of environmental and demographic conditions led to warfare ini- tially in the 13th century. Then at the end of that century, three things happened. First, the heartland of the Anasazi was abandoned, with some of the people moving south and oth- ers east into the Rio Grande Valley of New Mexico. Second, the conditions of environ- mental stress began to ease. The cycle of droughts ended and the pattern of soil erosion shifted to one of gradu- al soil aggradation. Finally, the pattern of endemic warfare that emerged in the Anasazi heartland changed as the emigrants moved out into other areas. It did not stop completely, but it decreased significantly and cycled up and down at a subregional level. In the Rio Grande Valley of New Mexico, where it appears some substantial portion of the emigrants settled, there are indications of high- ly defensive site locations for the first half of the 14th century. But the Rio Grande Valley represented a rich new resource zone at least in the initial years of heavy immigration from the west, with ample land and water. There are few signs of malnutrition. While there was certainly great ethnic diversity in the Rio Grande Valley, the primary causes of warfare were removed from the adaptive equation. Without the envi- ronmental pressures stimulating raiding and fighting, peace was a more adaptive option for the people in the valley. The level of conflict thus greatly abated in the 14th century as the people moved down off the hilltops; signs of violence occur only sporadically. The long historical perspective of archaeol- ogy gives another kind of insight into crosscul- tural patterns of warfare. We see from the data in the Southwest that tribal people cycle both in and out of endemic patterns of conflict. War- fare is not inevitable, even among ethnically diverse groups. Groups that are at war in one era or generation may well be at peace in the next. Without the long-term view of the archae- ological record, this pattern is difficult to see ethnographically. Groups known as being peaceful, such as the Xingu of Brazil, the Semai of Malaysia, or the Pueblos of northern New Mexico may be at one point in the cycle, while others known for raiding and fighting, such as the Yanamamo of Brazil, the Nuer of East Africa, and the Iban of Malaysia are at another point. Archaeology shows that warfare in tribal groups must be viewed in historical context. As the pressures leading to warfare abate so too does the warfare. Increased prevalence of war While archaeology helps highlight the cyclical nature of warfare among tribal peoples, it also helps show that the warfare loop of the cycle has been increasingly dominant as one moves closer in time to the present. Ten thou- sand years ago, there is almost no evidence for warfare anywhere on earth. Then, as the WESTERN TECHNOLOGY IN CHINA QING DYNASTY CARVED GLASS VASES By Chuimei Ho Department of Anthropology efore the 19th century, one of the few aspects of Western science to have been genuinely admired in the East — along with ship-building, cannon- casting, and astronomy — was the technology of glass making. Both blown and molded types of glass were made in China at least several centuries before the Christian era, often by private crafts- men not under royal patronage. The craft, how- ever, remained underdeveloped and even may have disappeared from time to time. Early glass workers seem to have made only small decora- tive items — beads, hairpins, pendants, rings, and sometimes perfume-type bottles. They also had few color choices: smudgy clear, blue, greenish blue, and opaque white. A breakthrough came about 1700 when Emperor Kangxi (1664-1722) set up a glasshouse with Bernard Kilian Stumpf, a Ger- man missionary, helping to build the furnace. Only then could large glass objects be made: vases, plates, bowls, and teacups as well as snuff bottles. Quality still seems to have been a problem, however. In 1756 Emperor Qianlong (1736-1796) was so annoyed with the inferiori- ty of certain officially commissioned glass bowls made in Canton that he forbade payment to the craftsmen. Two vases recently donated to the Field Museum show that progress was nonetheless being made in this period, particularly in the area of carved glass decoration. Part of the inspiration may have come from Qianlong’s technical consultant, the French Jesuit Gabriel- Leonard de Broussard, a trained glass specialist who served in the Imperial Glasshouse between 1742 and 1756. Glass in the Qianlong period improved so markedly that objects from the Imperial Glasshouse often formed part of official gifts to governments of other countries, including France. The impact of glass went beyond the palace and was felt even in private industry. By the time of the late 18th century, one reads from trading inventories that Chinese glass can- dlesticks were good enough for exporting to Japan, another Asian country where glass mak- ing traditions were old but not strong. By the WAR... world’s population grew to fill in available niches, states evolved and spread, and warfare appeared in the evolutionary trajectories of an increasing number of societies around the world. Furthermore, at least in the world areas with which I am familiar, the frequency of war- fare escalates over time. Five-hundred- or thou- sand-year cycles shorten to fifty- or one-hun- mid-I9th century, Chinese glass beads had even found markets in North America — at least some of the beads used by Indians in Alaska, British Columbia, and even California are thought to have come from China. The Museum’s new glass vases have the translucent yellow color associated with wares made for imperial use, and are of outstanding quality. They are a matched pair in a simple but classical shape — a plain long neck and a round body with rich carved decoration. They are heavy, with walls as thick as 1.1 cm. The vases were first blown to shape, then part of the surface was cut away leaving the designs in relief. The vases, completed in 1747, appear to be too classically Chinese in sentiment for Father de Broussard to have been directly involved — the designs come from conventional Chinese decorative art, and the technique of low relief carving in hard materials comes from tradition- al jade and stone work. But de Broussard is known to have been trying to produce glass objects that were exceptionally difficult in exe- cution. It is conceivable he oversaw the manu- facturing process while the actual labor was done by experienced glass workers from Guangdong or Shandong provinces. There are few precisely dated exam- ples of Chinese glass from Qianlong’s 60- year reign, and these vases are the earliest known. They were donated to the Muse- um by the daughters of the late Mr. and Mrs. Abba Lipman, who were long-time Chicago residents. Two of the daughters, Mrs. Dodie Baum- garten and Mrs. Bar- bara Kent, are mem- bers of the Collections Committee, the Muse- um’s recently orga- nized support group interested in ethno- graphic and historical artifacts. dred-year cycles. This pattern does not necessarily indicate that people in the modern age are somehow more inherently violent and culturally prone to warfare. Rather, the causes of warfare have become more prevalent. There is no relief for population pressure, and the sources of eco- nomic and environmental stress are unrelent- ing. Archaeology can be used to study the origins and develop- ment of patterns of conflict in prehis- toric times, and it offers some hope that such conflict need not be accepted as an inevitable con- comitant of ethnic diversity and cultur- al evolution. Cat. No, 259809 (detail) Cat. No, 259809 Cat. No, 259808 (detail) As these photos demonstrate, the best 18th-cen- tury Chinese glass carving is variable in depth, creating rounded design elements, Most of the work was refined by hand; later examples tend to be mechanical, cut with wheels so that the rigid relief is shown in a single level. The body of each vase has four panels, two circular and two fan-shaped. Surrounding the panels are intertwined bands and stylized lotus scrolls of the type called “foreign lotus” in China. These traditional design motifs and the conventional vessel shape indicate that the vases were probably meant for solemn occa- sions where a conservative feeling and exquisite workmanship would be appropriate. The engraved poems within the panels alse deserve attention. Qianlong was perhaps the most productive writer among all rulers in world history — he published nearly 10,000 poems. For these vases, where all the poems are about time and solitary feelings, we know that Qianlong selected at least one 9th-century verse for engraving along with several of his own, The thrill of a lifetime. . . and inner peace beyond imagining.
