Environmental Degradation and the Classic Maya Collapse at Copan, Honduras (a.d. 600–1250): Evidence From Studies of Household Survival
Authors: Paine Richard R. , Freter AnnCorinne
Published: October 2008

The Late Classic Maya abandonment of the Copan Valley, Honduras, began in the ninth centurya.d. and lasted approximately 250–300 years. The relationship between local ecological setting and residential group abandonment is examined by applying event-history analysis to the known occupation spans of 140 residential mound groups, dated by obsidian hydration. Late Classic households in ecologically vulnerable sections of the Copan Valley—as measured by slope, soil type, and natural vegetation—had significantly higher risk of abandonment than households in more ecologically stable settings. Abandonment risk rises sharply in all regions at the end of the seventh centurya.d. Both computerized agricultural simulations and settlement demographic reconstructions indicate that increased levels of agricultural intensification necessary to meet the subsistence needs of Copan's growing population would have led to large-scale erosion in upland areas and a significant reduction of soil fertility in all regions of the valley at that time. Mound-group abandonment patterns tend to support the hypothesis that environmental degradation played a dominant role in the collapse of the Copan polity.
Ancient Maya Trading Ports and the Integration of Long-Distance and Regional Economies: Wild Cane Cay in South-Coastal Belize
Authors: McKillop Heather
Published: October 2008

The importance of Maya sea trade was the sea's integrating role as provider of ritual and subsistence resources and ritual symbolism in the Maya economy. Coastal as opposed to inland transportation of obsidian and other exotics was enhanced because of coastal–inland exchange within the southern Maya lowlands. Results are presented on fieldwork conducted to investigate Maya sea trade by the South Coastal Archaeology in Belize (SCAB) project in the Port Honduras area of south-coastal Belize between Punta Gorda and Punta Negra. The research focused on identifying features characteristic of Maya trading ports that participated in long-distance trade and their impact on regional economies. The first part of the project, with fieldwork in 1982, identified the offshore island site of Wild Cane Cay as a trading port from the Classic through Postclassic periods (a.d. 300–1500). The discovery of some 30 sites during the second phase of the project, dating from the Protoclassic through the Postclassic periods (a.d. 1–1500), indicated that the coastal area had a long period of settlement in contrast to the inland area of southern Belize where settlement was concentrated during the Late Classic period (a.d. 600–900). The patterns of distribution of similar-sourced obsidian, and blades instead of cores within the south-coastal area indicated that some exotics were regionally distributed and that Wild Cane Cay was the nexus of regional distribution. The importance of coastal-inland exchange is underscored by the presence of specialized salt-production sites, coastal resources, and inland goods—notably “unit-stamped” pottery and moldmade figurine whistles.
Eastern Chajoma (Cakchiquel) Political Geography: Ethnohistorical and Archaeological Contributions to the Study of a Late Postclassic Highland Maya Polity
Authors: Hill Robert M.
Published: October 2008

The Chajoma were a major Late Postclassic polity in highland Guatemala. Referred to as the Akajal or Akul in the Annals of the Cakchiquels and Popol Vuh, their territory previously has not been fully defined. Based on a small group of sixteenth-century documents preserved in the records of a later litigation, it is now possible to identify the origins of the Chajoma, approximate the time of their arrival in their new territory, and define the extent of their territory. Combined with information on archaeological sites associated with this occupation, we can provisionally characterize the polity's composition and estimate its population.
The Architecture of the Teuchitlan Tradition of the Occidente of Mesoamerica
Authors: Weigand Phil C.
Published: October 2008

This study examines the geometry of the architecture of the Teuchitlan tradition of western Mexico. An argument will be made that these concentric circular buildings represent formal architectural planning and that they have cultural significance. The pattern dating from the Classic period (ca.a.d. 200–700) will be stressed.
Formal Architecture and Settlement Organization in Ancient West Mexico
Authors: Ohnersorgen Michael A. , Varien Mark D.
Published: October 2008

Classic-period settlement in the Teuchitlan region of West Mexico is characterized by the presence of unique, formal circular structures surrounded by residential areas. Previous research in the area has suggested the presence of a four-tiered settlement hierarchy based on the size of these structures, although, to date, this judgment has been made on a largely impressionistic basis. Our research further examines Weigand's Teuchitlan settlement data. We present a theoretical perspective for understanding the role of sites with formal architecture and evaluate the presence of a site-size hierarchy through volumetric estimations. Scenarios for site interaction are suggested by our use of a gravity model. Our primary goal is to propose models of Teuchitlan settlement organization, which can be tested by ongoing fieldwork in the region.
Datos preliminares sobre el descubrimiento de una tumba de tiro en el sitio de Huitzilapa, Jalisco
Authors: de la Vega Jorge Ramos , Camberos M. Lorenza López Mestas
Published: October 2008

Excavaciones recientes de rescate en el sitio de Huitzilapa, en la cuenca de Magdalena, centro de Jalisco, resultaron en el descubrimiento y la excavación de una tumba de tiro no saqueada. Se describen la tumba y sus contenidos, y se presenta una serie de fechas de radiocarbono que se concentran en el primer sigio de nuestra era. Las excavaciones proporcionan datos importantes sobre el contexto de las conocidas figuras de las tumbas de tiro, la cronología de este distinctivo complejo mortuorio y la relación de los ambos con la arquitectura de la tradición Teuchitlán.
Political Boundaries and Political Structure: The Limits of the Teuchitlan Tradition
Authors: Beekman Christopher S.
Published: October 2008

Many social scientists have proposed a relationship between the structure of a boundary and that of the system it delimits. Substantial anthropological and historical research has found the same tendency in analyses of traditional political structure. A model based on these findings was applied to the Teuchitlan tradition of Classic-period West Mexico, a region where the degree of political complexity and unification has been a subject of debate. A focused study of the eastern boundary of the Teuchitlan Valley was undertaken to examine the nature of its political structure. Fieldwork located a number of defensive features forming a well-structured boundary system in the La Venta corridor that connects the Teuchitlan and Atemajac Valleys. Other fortifications ringing the Teuchitlan Valley strongly suggest that a defensive network had been established to monitor access into the core of the Teuchitlan area. A unitary, territorial form of administration (following the work of Southall and Luttwak) is proposed as a model for political dynamics in the core region, but a review of the evidence for the more-distant Teuchitlan architecture suggests that, at most, only a hegemonic form of control more akin to that of the segmentary state was exercised outside of the core valley. A connection with long-distance resource acquisition is possible, but highly speculative at present.
Archaeological Interpretations of West Mexican Ceramic Art From the Late Preclassic Period: Three Figurine projects
Authors: Day Jane Stevenson , Butterwick Kristi , Pickering Robert B.
Published: October 2008

Scholars of West Mexico generally rely on the ceramic figurine tradition found in shaft tombs for interpreting the prehistory of the Late Preclassic period. Three new projects on shaft-tomb ceramics seek to advance our understanding of the Late Formative culture and societies of this region. First, ceramic figures are examined for evidence of the ball game in West Mexico; second, for cultural information about domestic and community organization; and third, for ways to differentiate authentic figures from modern reproductions.
Technological Change: Ceramic Mortuary Technology in the Valley of Atemajac From the Late Formative to the Classic Periods
Authors: Aronson Meredith
Published: October 2008

This study investigates prehistoric West Mexican mortuary activities as technological systems. Specifically, the production, distribution, and use of mortuary ceramics are considered within a social context. Technological changes occurring between the Late Formative and Classic periods (200b.c.–a.d. 700) at the site of Tabachines are compared to changes occurring at the center of the Teuchitlan tradition, 50 km away. At Tabachines, all aspects of the technology point to profound social change: tomb construction, treatment of the dead and offerings, and the approach to the production and use of mortuary ceramics. These changes are considered within a regional scope.
The Sayula Basin: Lifeways and Salt Flats of Central Jalisco
Authors: Valdez Francisco , Liot Catherine , Acosta Rosario , Emphoux Jean Pierre
Published: October 2008

Recent research in the Sayula Basin of central Jalisco is gradually presenting a fuller view of the lifeways that characterized the people who lived on this thoroughfare, traditionally known for its vast salt flats. Salvage excavations undertaken at two major sites have supplied a number of new elements that are confirming and expanding previous knowledge of the chronological sequence, the ceramic complexes, the uses of space within an apparently closed area, and the possible sphere of interactions developed by the pre-Hispanic inhabitants of this part of western Mexico. Special attention is given to evidence relating to the study of native salt production.
Monkey Business at Northern River Lagoon: A coastal–Inland Interaction Sphere in Northern Belize
Authors: Mock Shirley Boteler
Published: October 2008

Ongoing fieldwork at the coastal site of Northern River Lagoon (NRL) in northern Belize, a specialized saltmaking community, has revealed a consumer relationship with the large, inland, stone-tool-producing center of Colha during the Late to Terminal Classic. Artifact distribution suggests that this economic partnership involved the movement of salt, salted products, and trade goods to Colha in exchange for stone tools. This inland–coastal partnership was enhanced by a shared ideology reflected in the iconography of identical Palmar Orange-polychrome plates. The presence of the ideologically imbued plates in both elite and nonelite contexts suggests they were intended to strengthen group allegiance and reinforce territorial boundaries during this troubled time. This study stimulates new insights into the structure of ancient Maya coastal–inland interaction spheres in northern Belize, thereby facilitating comparisons between local areas within a regional context.
Decapitated Lunar Goddesses in Aztec Art, Myth, and Ritual
Authors: Milbrath Susan
Published: October 2008

Aztec images of decapitated goddesses link the symbolism of astronomy with politics and the seasonal cycle. Rituals reenacting decapitation may refer to lunar events in the context of a solar calendar, providing evidence of a luni-solar calendar. Decapitation imagery also involves metaphors expressing the rivalry between the cults of the sun and the moon. Huitzilopochtli's decapitation of Coyolxauhqui can be interpreted as a symbol of political conquest linked to the triumph of the sun over the moon. Analysis of Coyolxauhqui's imagery and mythology indicates that she represents the full moon eclipsed by the sun. Details of the decapitation myth indicate specific links with seasonal transition and events taking place at dawn and at midnight. Other decapitated goddesses, often referred to as earth goddesses with “lunar connections,” belong to a complex of lunar deities representing the moon within the earth (the new moon). Cihuacoatl, a goddess of the new moon, takes on threatening quality when she assumes the form of atzitzimimeattacking the sun during a solar eclipse. The demonic new moon was greatly feared, for it could cause an eternal solar eclipse bringing the Aztec world to an end.
The Vanderbilt Petexbatun Regional Archaeological Project 1989–1994: Overview, History, and Major Results of a Multidisciplinary Study of the Classic Maya collapse
Authors: Demarest Arthur A.
Published: October 2008

The background, research design, structure, personnel, and history of investigations of the Vanderbilt Petexbatun Archaeological Project are summarized and critiqued. The major findings of each of the dozen subprojects of this multidisciplinary investigation of Maya civilization in the southwestern Peten region of Guatemala are reviewed. Subproject results include important new evidence on Classic Maya history, warfare, ecology, nutrition, cave ritual, social organization, and trade. These are summarized with particular emphasis on the implications of the Petexbatun findings for theories of the decline of southern lowland Maya civilization at the end of the Classic period.
Classic Maya Defensive Systems and Warfare in the Petexbatun Region: Archaeological Evidence and Interpretations
Authors: Demarest Arthur A. , O'Mansky Matt , Wolley Claudia , Van Tuerenhout Dirk , Inomata Takeshi , Palka Joel , Escobedo Héctor
Published: October 2008

From 1989 to 1996, excavation and surveys were carried out at dozens of sites and intersite areas in the southwestern Peten by the Defensive Systems Subproject of the Vanderbilt Petexbatun Regional Archaeological Project and by subsequent related Vanderbilt investigations. The excavations and analyses explored fortification systems, related settlement, and artifactual evidence. Beginning at abouta.d. 760, the major centers of the Classic Maya civilization in the Petexbatun region were fortified by a massive expenditure of labor on defensive walls of masonry, usually surmounted by wooden palisades. As warfare accelerated, major centers and later even small hilltop villages were located in highly defensible positions and were fortified by walls, palisades, moats, and baffled gateways. Despite these efforts, all major centers were virtually abandoned by the early ninth century. Bya.d. 830, only the island fortress of Punta de Chimino and a very reduced and scattered population remained in the Petexbatun region.
The Paleoecology and Ancient Settlement of the Petexbatun Region, Guatemala
Authors: Dunning Nicholas , Beach Timothy , Rue David
Published: October 2008

The Petexbatun region has a series of upland ridges surrounded by lowland wetlands. In Preclassic times, ancient Maya peoples began colonizing the region along waterways. Although few in number, they cleared large areas of upland tropical forest for agriculture and induced significant soil erosion. Population contracted in the region during the Early Classic, and mature tropical forest growth returned. During the Late Classic, population expanded rapidly across the region, forest clearance resumed, and desirable, intensively cultivated, upland areas were divided by an elaborate wall system. Upland agriculture during the Late Classic included the use of several types of terracing that significantly checked soil erosion during this period. Considerable variation may have existed between the urban agriculture practiced in the region's three major centers—Dos Pilas, Tamarindito, and Aguateca.
Biological Perspectives on the Collapse of the Pasión Maya
Authors: Wright Lori E.
Published: October 2008

This paper reviews bioarchaeological research that aimed to test the biological correlates of ecological explanations for the Maya collapse using human skeletal remains from five sites in the Pasión region. Stable isotope ratios of bone collagen and alkaline earth ratios in bone minerals do not support the expectation of increased reliance on maize and declining meat consumption during the final years of Pasión occupation. Moreover, skeletal pathology does not illustrate any increment in anemia, infectious disease, or dental growth disruption that is predicted to have been a consequence of high population density and deteriorating nutrition. Instead, changes in the social distribution of foods during the Terminal Classic supports the mounting evidence that the Pasión collapse was fueled more by sociopolitical transformations than environmental ones.
Changing Ceramic Production and Exchange in the Petexbatun Region, Guatemala: Reconsidering the Classic Maya Collapse
Authors: Foias Antonia E. , Bishop Ronald L.
Published: October 2008

The typological, modal, and chemical analyses of the pottery from the Petexbatun region of southwestern Peten, Guatemala, are used to establish a regional ceramic chronology and to assess three theories used to explain the Classic Maya collapse of the ninth and tenth centuriesa.d.The three explanations are based on: (1) foreign invasion; (2) commercialization; and (3) internal warfare. Each of these theories suggests different changes in the regional ceramic-production and -exchange systems of the Petexbatun. Shifts in the ceramic production system are monitored using a standardization study, while instrumental neutron-activation analysis (INAA) is used to model changes in interregional exchange. The results of these analyses indicate that there was a continuity in the ceramic assemblage from the Late Classic Nacimiento phase (a.d.600–830) to the Terminal Classic Sepens phase (a.d.830–950). Together with little change in architectural, mortuary, and other artifactual styles, this finding suggests that no foreign groups invaded the Petexbatun region, and therefore did not lead to the collapse in the Pasion region. The small decreases in pottery standardization and the minor shifts in interregional exchange do not support the second theory that a major reorganization of Maya economy undercut the power base of the Maya elite class. On the other hand, these small decreases in standardization and in the scale of exchange do support the third theory, which suggests that internal warfare between the regional polities disrupted exchange, leading to more localized production. The stability of the ceramic production and exchange systems in the Petexbatun region throughout the collapse also suggests that the political and economic systems were largely disconnected. These findings suggest that internal political processes leading to an increase in competition and to intensified warfare were important factors in the Classic Maya collapse of the Petexbatun region in Peten, Guatemala.
Reconstructing Classic Maya Socioeconomic Differentiation and the Collapse at Dos Pilas, Peten, Guatemala
Authors: Palka Joel W.
Published: October 2008

Three field seasons of extensive residential archaeology at Dos Pilas, Peten, Guatemala, provide important data for the examination of ancient Maya social structure and the Classic Period collapse in the Petexbatun region. A sampling strategy guiding excavations in structures of different size and architectural configuration enables us to reconstruct the multifaceted, segmented nature of Maya social inequalities and helps to elucidate the effects of the collapse on the lives of people of various socioeconomic ranks and statuses. Other significant findings of the project include hieroglyphic vessels and stone sculptures in nonroyal elite domestic compounds, postcollapse occupation in the settlement, as well as continued craft production and interregional trade into Terminal Classic times and after elite abandonment of the site. The results of household archaeology at Dos Pilas, which demonstrate that elites were affected first and foremost during the collapse, support theories of intensified elite competition, socio-political instability, and warfare for the Maya downfall in the Petexbatun Region, and not environmental degradation or breakdowns in interregional trade.
Arroyo de Piedra: Sociopolitical Dynamics of a Secondary Center in the Petexbatun Region
Authors: Escobedo Héctor L.
Published: October 2008

Arroyo de Piedra occupies a strategic position between the sites of Dos Pilas and Tamarindito, the dominant polities in the Petexbatun region. Temples, palaces, sculptured monuments, quarries, and a defensive wall reflect the importance of this small site. Archaeological and epigraphic investigations conducted by Vanderbilt University from 1990 to 1994 demonstrate that Arroyo de Piedra was founded and ruled by members of the royal family of Tamarindito during the Early Classic. In the Late Classic, Arroyo de Piedra was absorbed by the expansionistic Dos Pilas dynasty through a matrimonial alliance. The marriage was apparently imposed by means of coercion as suggested by evidence of intentional destruction of local sculpture. The center was abandoned during the Terminal Classic, after the fall of Dos Pilas.
Glimpses of the Dark Side of the Petexbatun Project: The Petexbatun Regional Cave Survey
Authors: Brady James E. , Scott Ann , Cobb Allan , Rodas Irma , Fogarty John , Sánchez Monica Urquizú
Published: October 2008

The Petexbatun Regional Cave Survey (PRCS) is the first large cave study to be undertaken as part of a major archaeological expedition. The survey's primary objective was assessing the extent to which surface architecture at Dos Pilas was configured by features in the sacred landscape. All three of the major architectural complexes at the site had a direct relation to caves, and a number of important secondary buildings and even residential units were deliberately laid out to incorporate caves. Excavation revealed evidence of Preclassic utilization of all of the major caves, indicating that their status as sacred landmarks had been established long before the eighth century florescence of the site. The importance of the caves in site configuration was mirrored in the artifact assemblage. Despite the survey's much smaller size, the cave investigations recovered 20–50% more of the overall assemblage at Dos Pilas in an array of artifact categories. A review of the archaeological literature suggests that the importance ascribed to caves at Dos Pilas in both site configuration and local economy can be found elsewhere and probably reflects a much wider pattern of utilization.
Punta Canbalam in Context
Authors: Dahlin Bruce H. , Andrews Anthony P. , Beach Timothy , Bezanilla Clara , Farrell Patrice , Luzzadder-Beach Sheryl , McCormick Valerie
Published: October 2008

Investigations at Punta Canbalam on the Gulf Coast of Campeche reveal it is probably the largest of several important but underreported trading sites on the pan-Mesoamerican maritime trade route. The coastline has been unstable for the last thousand years, subjecting the site to sea level changes and repeated episodes of beach erosion and redeposition. The relatively dense scatter of temporally mixed, highly weathered sherds and other artifacts on an exceedingly narrow, modern beach indicates that it is all secondarily deposited and that its original location was offshore. An interdisciplinary team is beginning to recognize clues in its environmental and cultural contexts as to where this peripatetic site was originally located and the extent to which it depended upon exchanges of salt, petty commodities from inland, and canoe-borne exotics from afar. This predominantly Terminal Classic and Early Postclassic site likely served as a port of entry for obsidian, jade, fine-paste ceramics, and other goods for the nearby inland city of Chunchucmil. It also probably supplied the interior with marine and estuarine food and ornamental and ritual products in exchange for inland agricultural products and other items.
The Lowland Maya “Protoclassic”
Authors: Brady James E. , Ball Joseph W. , Bishop Ronald L. , Pring Duncan C. , Hammond Norman , Housley Rupert A.
Published: October 2008

The term “Protoclassic,” employed regularly but inexplicitly in the literature of lowland Maya archaeology, has become increasingly nebulous and ambiguous in both meaning and usage. This paper reviews the history and use of the term and presents a formal redefinition of the Protoclassic as a ceramic stage based explicitly and exclusively on ceramic criteria. Some suggestions regarding future use of the term also are offered. The paper further addresses and resolves a number of persisting questions regarding Protoclassic orange wares, including problems concerning the actual existence of the “Aguacate ceramic group.” and the relationships of Aguacate-group pottery to other emergent orange wares of the terminal Late Preclassic and initial Early Classic periods. The nature and significance of the “Holmul I Style,” the “Floral Park Ceramic Sphere.” and the relationships of the two to each other and the larger, redefined “protoclassic” ceramic stage also are examined. A spatial distribution for protoclassic ceramics considerably expanded over what has ever been reported previously is described, and Chronometric data are presented to support a revised chronology for the protoclassic ceramic stage. Finally, ceramic data are offered that suggest a real subdivision of the protoclassic ceramic stage into an early, emergent facet originating entirely within Late Preclassic lowland traditions, and a later, fully “Classic” facet corresponding to the early Tzakol (Tzakol 1) ceramic horizon.
Community Organization in the Parroquia de Yaxcaba, Yucatan, Mexico, 1750–1847
Authors: Alexander Rani T.
Published: October 2008

The following paper examines archaeological variability in community organization of sites in the parroquia de Yaxcaba. Yucatan, Mexico, froma.d.1750 to 1847. Using historical and archaeological evidence, the course of political-economic change in Yucatan is followed from the recovery of the Indian population in 1750, through the Bourbon reforms and Independence from Spain, to the Caste War of Yucatan in 1847 in order to assess its implications for continuity or discontinuity of Maya adaptive patterns. Three settlements—a pueblo, a hacienda, and an independent rancho—were intensively mapped to reveal patterns of house lots, streets, features, plazas, and public architecture. Differences in spatial organization among the settlements can be specifically linked to variation in population growth, tax structure, and land stress coincident with changes in the colonial regime. Variation in household production strategies and the choice of tactics that minimize subsistence risk were largely dependent on the community's degree of integration with the colonial system. The evidence from Yaxcaba suggests that two key processes are particularly important in determining articulations between rural and urban areas: disenfranchisement from the means of production and the extension of credit. These two processes affect variation in the relations of production that partly explain how communities either become entangled in or remain apart from political-economic change.
The Ceramics of Cuello, Belize
Authors: Kosakowsky Laura J. , Pring Duncan C.
Published: October 2008

The site of Cuello in northern Belize provides a long ceramic sequence from the early Middle Preclassic, ca. 1200b.c., to the Late Preclassic, sometime in the fourth centurya.d.Excavations begun at Cuello in 1975 were completed in 1993. The initial controversy concerning the chronological placement of the earliest pottery of the Swasey and Bladen complexes is challenged by examining the 1992 and 1993 excavated material in a “blind analysis,” without benefit of stratigraphic information. The results demonstrate conclusively the stratigraphie priority of Swasey ceramics below Bladen, which in turn lie below pottery of the Middle Preclassic Lopez-Mamom complex. Cuello operated within the homogeneous Mamom ceramic sphere during the Middle Preclassic and within the Chicanel ceramic sphere during the Late Preclassic. The ultimate breakup of the Chicanel sphere resulted in Cuello's adherence to the older ceramic traditions, while other Maya sites had begun the production of polychrome pottery. Cuello represents one of the best-known Middle Preclassic Maya sites yet investigated, and it provides an important perspective on this poorly understood time period in the Maya lowlands.
Refining an Early Formative Ceramic Sequence From the Chiapas Coast of Mexico
Authors: Lesure Richard G.
Published: October 2008

Analysis of Early Formative ceramics from the site of Paso de la Amada, on the coast of Chiapas, Mexico, yields a refined sequence for the period 1400–1000b.c.A simple key has been developed to classify midden assemblages. Its utility for creating chronologically sensitive groupings is confirmed by multidimensional scaling of 32 units. The refined ceramic sequence provides a basis for investigating short-term sociopolitical dynamics during the Early Formative period.
Famine Vulnerability in the Contact-Era Basin of Mexico
Authors: Whitmore Thomas M. , Williams Barbara J.
Published: October 2008

This study simulates vulnerability to famine and food poverty among peasant households in the Basin of Mexico two decades after the Conquest. Using demographic and cadastral data recorded in theCódice de Santa María Asunción(Tepetlaoztoc), vulnerability is assessed by comparing household and patio-group (household compound) food production to consumption needs at the same scales, Modeling of food production of the principal subsistence crops (maize, beans, and maguey) uses the soil types noted for each field in the Asuncion document and a production model that accounts for soil-productivity differences. Both typical and poor years are modeled. Household and patio-group food needs are based on the codex data for each individual in the community. The study reveals that 60% of the population was at risk of famine in a poor year and that up to 16% would have suffered food poverty in a typical year. Nevertheless, even in a poor year, 40% of the population would have had adequate-or-better nutrition. Thus, this analysis supports contrasting views of early Contact-period nutrition. Because of the unequal distribution of food-production resources in Nahua society, some commoner households were usually adequately fed, while others normally suffered chronic undernutrition. Patio groups represent a possible response to this situation, as analysis by patio group indicated reduced vulnerability to food poverty. Land per capita ratios appear to be the best explanation of the differences in food poverty and famine risk among the households or patio groups.
The Ceramic Chronology of Ek Balam, Yucatan, Mexico
Authors: Bey George J. , Bond Tara M. , Ringle William M. , Hanson Craig A. , Houck Charles W. , Lope Carlos Peraza
Published: October 2008

Since 1984, the Ek Balam Project has been investigating the organization and developmental history of a large Maya polity in the northeastern part of the Yucatan Peninsula. The survey included both urban Ek Balam, the largest regional center during the Late Classic period (a.d.600–900), covering a minimum of 12 km2, and its rural hinterland. One result of this project has been the construction of a preliminary ceramic history of the region, the subject of this report. Evidence supports a sequence of occupations extending from the Middle Preclassic through the Hispanic period (600b.c.–a.d.1600). The ceramic sequence, constructed from a type-variety analysis of more than a quarter of a million pieces of pottery from surface survey and excavations, consists of six preliminary ceramic complexes. This ceramic analysis extends our understanding of Maya cultural development in the northern Maya lowlands to a largely unknown area of the peninsula.
Diachronic Ceramic Evidence and its Social Implications in the Chikinchel Region, Northeast Yucatan, Mexico
Authors: Kepecs Susan
Published: October 2008

In this paper I present new, surface-collected ceramic data from the previously little-known Chikinchel region in northeast Yucatan. My goals are twofold: first, to expand the utility of surface-collected materials by suggesting a technological approach (paste analysis) to classify small or eroded sherds; and second, to place Chikinchel into the larger spatial and temporal framework of the northern Maya lowlands. The ceramic analyses presented here span the Late Formative through Spanish Colonial periods. Diachronic changes in the regional distributions of the different wares that compose the Chikinchel ceramic inventory are demonstrated and discussed in terms of larger processes occurring across the peninsula.
Before the Florescence
Authors: Smyth Michael P.
Published: October 2008

The period preceding the Terminal Classic florescence in the Puuc region of Yucatan, Mexico has not received adequate research attention. Recent comprehensive site survey and excavation at Chac II (Chac) are exploring Puuc origins and have begun to redress the lack of chronological understanding regarding the region by independently linking architectural styles to ceramic sequences via a program of absolute dating. Results to date suggest that Chac was a significant Early Classic center (a.d.300–600) that also experienced a major Late Classic (a.d.600–800) occupation. Multiple lines of chronological evidence, including buildings with a mix of early architectural styles and associated pre-Cehpech and Cehpech ceramics (a.d.800–1000) within sealed architectural and stratigraphic contexts, suggest a period of architectural transition and the antecedents of Cehpech ceramics dating to the sixth century. These new chronological data and associated evidence for foreign contacts perhaps reaching to central Mexico argue for the assignment of a Middle Classic period (a.d.500–700) to the region, with broad evolutionary implications for Puuc origins and pan-Mesoamerican contacts.
Yula, Yucatan, Mexico
Authors: Anderson Patricia K.
Published: October 2008

A major impediment to understanding the Terminal Classic to Early Postclassic transition in northern Yucatan has been the lack of a reliable ceramic chronology defined from stratigraphic contexts at the site of Chichen Itza. The temporal relationship of Cehpech and Soluta ceramics is central to resolving the issue of the correct chronological placement of Chichen Itza. The results of stratigraphic excavations at Yula, a small site 5 km south of Chichen Itza, provide the strongest evidence to date that Cehpech and Sotuta ceramics were contemporaneous. Statistical analysis of pottery composition by stratum confirms a positive correlation between Sotuta and Cehpech, which are clearly differentiated from earlier pottery. Rather than following a linear sequence in which Cehpech precedes Sotuta, as suggested by R. E. Smith and other early researchers, these two slatewares represent coeval regional variation. Thus, the major occupation of Chichen Itza dates not to the Early Postclassic, but to the Terminal Classic. The results of this research contribute toward the redefinition of the Terminal Classic and Early Postclassic periods in the northern Maya lowlands.
The Chronology of Yaxuna
Authors: Suhler Charles , Ardren Traci , Johnstone David
Published: October 2008

Research at the ancient Maya city of Yaxuna, located in the heart of the Yucatan Peninsula, has provided sufficient data to suggest a preliminary chronological framework for the cultural development of this large polity. Primary ceramic and stratigraphie data are presented to support a five-phase scheme of cultural history, encompassing the Middle Formative through Postclassic periods (500b.c.–a.d.1250). In addition to chronological significance, the political ramifications of a pan-lowland ceramic trade are addressed. Yaxuna experienced an early florescence in the Late Formative–Early Classic periods, when it was the largest urban center in the central peninsula. A second renaissance in the Terminal Classic period was the result of Yaxuna's role in an alliance between the Puuc and Coba, in opposition to growing Itza militancy. This paper proposes a chronological framework for the cultural development of one northern Maya region in order to facilitate an understanding of this area as part of the overall history of polity interaction and competition in the Maya lowlands.
The Return of Quetzalcoatl
Authors: Ringle William M. , Negrón Tomás Gallareta , Bey George J.
Published: October 2008

Continuing analysis of the site of Chichen Itza suggests that its construction dates primarily to the Late Classic period, ca.a.d.700–1000, rather than the Early Postclassic. This paper examines the implications of this redating for the well-known “Toltec” problem. Since Chichen largely antedated Tollan-phase Tula, we conclude that what is usually identified as Toltec imagery in fact dates to an earlier Epiclassic horizon extending from Morelos and Puebla to the Gulf Coast and Yucatan. Chichen Itza, we suggest, was the eastern node in a network of shrine centers dedicated primarily to Quetzalcoatl/Kukulcan. This network transcended political boundaries and included such sites as Cholula, Cacaxtla, El TajIn, Xochicalco, and ultimately Tula. The Quetzalcoatl cult is manifested by a specific complex of traits and seems to have expanded militarily with messianic vigor. Pilgrimage was also an important activity at these centers. This cult axis apparently continued into the Postclassic period, and was responsible for the distribution of the Mixteca-Puebla art style. In Yucatan, Mayapan would seem to have assumed Chichen's position as the major Yucatecan node, although accompanied by several new shrines along the Caribbean coast.

A comprehensive site survey and excavation program took place in 1995 and 1996 at the Maya center of Chac II (Chac) located within the Puuc hills region of Yucatan, Mexico. This work presents a body of evidence in support of the idea that Chac was an important center beginning in the Early Classic period (a.d.300–600) that experienced significant foreign contacts. In addition, multifaceted data from surface, soil, architectural, and excavated contexts are addressing major questions pertaining to architectural and ceramic chronologies, the founding of the Puuc stoneworking tradition, site activity areas, and patterns of land use. Furthermore, dating indicates that Chac predated Sayil and that the two sites have a close geographical relationship. Also, terrace agriculture appears to have been widespread at Chac, contrasting greatly with Sayil where intensive gardening was widely practiced. In light of the new information from Chac, we argue that the traditional models of Puuc origins are inadequate. Investigations at a major Early Classic site in the heart of the Puuc region suggests that the region's rise was indigenous coupled with external ties to foreign groups reaching to central Mexico. The site of Chac is thus taking on strategic importance for understanding the origins of Puuc civilization, providing a rare opportunity to study a Maya center that was on the brink of urbanism in one of the most urban ancient Maya areas. These new data are helping to elucidate the nature of Maya urbanism in the Puuc region and establish the kinds of cultural links that existed between the northern Maya Lowlands and the rest of Mesoamerica during the Classic period.
Leadership at Sayil
Authors: Carmean Kelli
Published: October 2008

This paper explores the nature of community leadership within the Late–Terminal Classic Maya site of Sayil, Yucatan, Mexico. The distribution of political and religious activities—as represented archaeologically by cylindrical stone monuments (“altars”) and Oxkutzcab Applique censers—is examined. It is argued that such activities are dispersed into the upper ranks of Sayil society, rather than concentrated in the royal, ruling sector. It is further argued that the residential areas in which political and religious activities were concentrated may have been the loci of lineage heads of Sayil, who maintained important leadership roles despite attempts at centralization by the rulers.
Classic Maya Mortuary Anniversaries at Piedras Negras, Guatemala
Authors: Fitzsimmons James L.
Published: October 2008

In her studies of Maya hieroglyphs at the site of Piedras Negras, Guatemala, Tatiana Proskouriakoff (1960) observed that Maya rulers often celebrated the anniversary of their accession. She recognized that a number of repeated dates were not associated with accession, but could offer no explanation for them. Recent study of the inscriptions associated with these dates has revealed a wealth of ritual information: the rulers of Piedras Negras commemorated the anniversaries of births, deaths, and mortuary activities with a number of ceremonies. This report addresses those ceremonies at Piedras Negras and examines the hieroglyphic and archaeological evidence for similar events at other Classic Maya sites.
Deity Relationships in Mesoamerican Cosmologies

Published: October 2008

The study of deity images in pre-Columbian Mesoamerican artworks and pictographic texts has been dominated by a concern to classify them for identification of the individual gods. The usual approach has been taxonomic classification, emphasizing the attributes consistently shared by various images to distinguish them as members of a single class (i.e., a single deity). However, identifying criteria are shared by more than one deity class, and the desired consistency in a set of traits for class membership has never been realized, such that scholars still disagree as to the proper identification of these images. This study takes a different approach, by examining the relationships among gods manifested in both imagery and text. It focuses on the Maya God L, who shares some identifying features with God M and also shares certain contexts with the God Bolon Yokte. These associations reflect their spatiotemporal alignments, with God L representing the stability of the primordial cosmic center, whereas Gods M and Bolon Yokte are “travelers” who move within the periphery. From these relationships we begin to explain not only the fluidity of deity imagery, but also how deities served as metaphoric representations of dynamic social and cosmic processes.
Tomb Use and Reuse in Oaxaca, Mexico

Recently, a major debate has arisen over the interpretation of Monte Albán Tomb 7. This debate hinges, in part, on whether the skeletal assemblage comprised either primary or secondary burials. Previous studies of Mesoamerican mortuary practices generally have recognized only primary and secondary burials in tombs. Findings from a recently excavated tomb in Ejutla, Oaxaca, demonstrate that a third possibility exists: multiple-interment tomb assemblages. These assemblages result from a process we call “ongoing tomb use.” Based on comparisons with the Ejutla interments we propose that the Monte Albán Tomb 7 assemblage may have resulted from ongoing tomb use.
Context, Cult, and Early Formative Period Public Ritual in the Mixteca Alta
Authors: Blomster Jeffrey P.
Published: October 2008

From the Early and Middle Formative periods, hollow ceramic-baby figurines in the Olmec style—representing a suite of shared symbols and iconography—appear at sites throughout Mesoamerica. Hollow babies are usually reported without provenience, which has prevented a context-based analysis. The recent discovery of a hollow-baby figurine in a bell-shaped pit in the Mixteca Alta of Oaxaca provides the opportunity to examine the role and purported distribution of these objects across Mesoamenca. Based on consideration of the Etlatongo hollow-baby image, a semiotic analysis of contemporaneous solid figurines from Oaxaca, and the volume and nature of its bell-shaped-pit context, hollow babies are interpreted as ritual paraphernalia used in display and public ceremonies that reflect the emerging social ranking of this period. Moving beyond a socioeconomic interpretation, the interregional relationships expressed through hollow-baby figurines are suggested to evince participation in a regional cult.
Multiethnicity or Multiple Enigma

During the summer of 1995, an intensive archaeological survey of the Río Talgua drainage in eastern Honduras was conducted after the discovery of the Talgua Cave in the Department of Olancho. One important goal of this survey was the identification of the indigenous population responsible for depositing the ninth-centuryb.c.human burials found upstream in Talgua Cave. In addition to this survey, four other caves were found and/or explored during this season, and limited excavations were also conducted at the mounded site of Talgua downstream and at the ceramic-production site of Chichicaste in the mountains to the west. Preliminary analysis of the architecture and ceramics from 39 newly identified archaeological sites in the Talgua Valley suggests that all appear to date to the Late Classic period (a.d.600–900), leaving the location of the Middle Formative period population unresolved. A review of the survey, cave, and ceramic data, however, does reveal possible information about the multiethnic nature of the regional political system and local social structure that existed in this previously unstudied area of Central America.

Resonant modulation of the flow in a tidal channel
Authors: Mullarney Julia C. , Hay Alex E. , Bowen Anthony J.
Published: October 2008

The coupling between a quarter‐wave resonance in a coastal bay and a Helmholtz mode in an adjacent cove (connected to the bay through a narrow channel) is investigated by comparing field measurements to analytical and numerical model predictions. Pressure and velocity spectra from locations throughout the bay reveal an oscillation with a period of approximately 1 hour, consistent with a quarter‐wave seiche mode. The associated sea surface displacements throughout the bay are small (less than 5 cm RMS, i.e., only 10% of the tidal elevation). Velocities within the channel are significantly modulated in the 1‐hour band, with amplitudes up to 40% of the peak tidal current. The analytical model shows that the modulation of the channel flow results from the interaction between the quarter‐wave mode in the main basin and a Helmholtz resonance in the cove, also with a period near 1 hour. The amplitude and phase of the 1‐hour oscillation varies through the tidal cycle because of the change in Helmholtz frequency with tidal elevation. Good quantitative agreement between the data and the model predictions is obtained if a drag coefficient approximately 3–4 times larger than the classical value of 3 × 10−3 is used in the channel and cove.
