Ritual responses to drought: An examination of ritual expressions in Classic Maya written sources

Planting and rain-beckoning rituals are an extremely common way in which past and present human communities have confronted the risk of drought across a range of environments worldwide. In tropical environments, such ceremonies are particularly salient despite widespread assumptions that water supplies are unproblematic in such regions. We demonstrate for the first time that two common but previously under-appreciated Maya rituals are likely planting and rain-beckoning rituals preferentially performed at certain times of the year in close step with the rainy season and the Maya agricultural cycle. We also argue for considerable historical continuity between these Classic Maya ceremonies and later Maya community rituals still performed in times of uncertain weather conditions up to the present day across Guatemala, Belize, and eastern Mexico. During the Terminal Classic period (AD 800-900), the changing role played by ancient Maya drought-related rituals fits into a wider rhetorical shift observed in Maya texts away from the more characteristic focus on royal births, enthronements, marriages, and wars towards greater emphasis on the correct perpetuation of key ceremonies, and we argue that such changes are consistent with palaeoclimatic evidence for a period of diminished precipitation and recurrent drought.     

Kingship in the Late Preclassic Maya Lowlands: The Instruments and Places of Ritual Power

The Maya of Central America constitute the only truly literate pre-Columbian civilization. Analysis of ancient Maya hieroglyphic texts and accompanying images dating from the Classic period (A.D. 200–900) documents the presence of a central and pervasive institution of governance: ahaw. The material symbol systems of the Lowland Maya of the protoliterate Late Preclassic period (350 B.C.-A.D. 100), as evinced in monumental decorated buildings and in portable art, suggest that these Maya innovated ahaw, the institution of kingship. The authority of ahaw rested upon direct descent and spiritual communion with the ancestors of all Maya, the Ancestral Heroes. Along with noble lineage, ahaw claimed charismatic power through the performance of shamanistic ritual. The Late Preclassic antecedents of the shamanistic parameters of ahaw are discussed in light of Classic and Postclassic ritual expressions.     

Population structure of the Classic period Maya

This study examines the population structure of Classic period (A.D. 250-900) Maya populations through analysis of odontometric variation of 827 skeletons from 12 archaeological sites in Mexico, Guatemala, Belize, and Honduras. The hypothesis that isolation by distance characterized Classic period Maya population structure is tested using Relethford and Blangero's (Hum Biol 62 (1990) 5-25) approach to R matrix analysis for quantitative traits. These results provide important biological data for understanding ancient Maya population history, particularly the effects of the competing Tikal and Calakmul hegemonies on patterns of lowland Maya site interaction. An overall F(ST) of 0.018 is found for the Maya area, indicating little among-group variation for the Classic Maya sites tested. Principal coordinates plots derived from the R matrix analysis show little regional patterning in the data, though the geographic outliers of Kaminaljuyu and a pooled Pacific Coast sample did not cluster with the lowland Maya sites. Mantel tests comparing the biological distance matrix to a geographic distance matrix found no association between genetic and geographic distance. In the Relethford-Blangero analysis, most sites possess negative or near-zero residuals, indicating minimal extraregional gene flow. The exceptions were Barton Ramie, Kaminaljuyu, and Seibal. A scaled R matrix analysis clarifies that genetic drift is a consideration for understanding Classic Maya population structure. All results indicate that isolation by distance does not describe Classic period Maya population structure.     

A Zooarchaeological Test for Dietary Resource Depression at the End of the Classic Period in the Petexbatun,Guatemala

Zooarchaeological analyses of animal remains from the Petexbatun sites in the Guatemalan lowlands provide proxy evidence to test a hypothesis of dietary insufficiency during the Maya “collapse.” Ecological foraging theory and resource depression models are used to interpret animal use patterns before and after the disintegration of the Petexbatun polity at the end of the Late Classic period (around a.d. 800). Environmental failure models of the Maya “collapse” at the end of the Late Classic imply that a dietary insufficiency, and particularly a lack of animal resources, was associated with the political and social transitions of this period. However, the results of this zooarchaeological study do not support this hypothesis and point instead to very limited early reductions of only highest-ranked dietary species. The lack of evidence for specific resource depression associated directly with the period of political collapse does not support a model of environmental failure during political disintegration in the Petexbatun. Correlations are found between animal use patterns and the specifics of site size and periods of peak political activity, suggesting that small-scale resource depressions might have resulted at some sites during early periods of human population growth, site expansion, and increasing political activity.     

The causes and consequences of deforestation among the prehistoric Maya

The collapse of the Classic Maya state is investigated from an ecological perspective. Settlement and palynological data from the Maya center of Copan, Honduras, are presented which indicate that substantial clearing of the upland pine forest had occurred prior to and during the abandonment of that urban center. A comparative use- rate analysis suggests that the increased clearing of pine was primarily caused by demands for domestic fuel wood by an expanding urban population. This forest mismanagement is directly linked to accelerated erosion rates which are considered primary elements in the collapse of the Maya state.     

Bioarchaeological investigation of ancient Maya violence and warfare in inland northwest Yucatan,Mexico

This study investigates evidence of changes and continuities in ancient Maya violence and warfare in inland northwest Yucatan, Mexico from the Middle Preclassic (600–300 BC) to the Postclassic (AD 1050–1542) through bioarchaeological analysis of cranial and projectile trauma. It is hypothesized that the frequency of violence increases before the Classic Maya collapse and remains high during the Postclassic period. It is also hypothesized that the flat, open terrain was conducive to warfare and resulted in higher trauma frequencies than in other parts of the Maya area. Results show that the frequency of cranial trauma decreases before the Classic collapse and increases in the Postclassic, partially matching the expected chronological trends. The frequency of cranial trauma does not differ significantly from other Maya regions but the pattern does: for all periods, males have more healed injuries than females and they are concentrated on the left side of the anterior of the skull. Some injuries appear to be from small points hafted in wooden clubs. In addition, projectile trauma is evident in a scapula with an embedded arrowhead tip, the first such case reported in a Maya skeleton. Overall, these results suggest greater reliance on open combat and less on raids in this region compared with other parts of the Maya area, possibly due to the flat, open terrain, though the identification of perimortem trauma in both women and men indicates surprise raids on settlements were also practiced.

Classic Maya State, Urbanism, and Exchange: Chipped Stone Evidence of the Copán Valley and Its Hinterland

In this article I use quantitative data from 91,916 pieces of chipped stone artifacts from the Copán Valley and its hinterland in Honduras to understand better the nature and role of exchange in the development of a Classic Maya state-level society. The results of this study suggest that intraregional exchange was more crucial for state development than was longdistance exchange. The management of procurement and exchange of utilitarian commodities, such as Ixtepeque obsidian blade cores, along with other factors, played a significant role in the development of the Copán state. In contrast to other major Maya lowland states, the Copán state directly obtained obsidian blade cores from nearby sources, distributed them to local leaders at Copán, and exported them to local rulers in neighboring regions. In this sense, the Classic Copán state maintained a centralized and integrated political and economic organization based on far more than kinship, ideology, and ritual, [exchange, complex society, urbanism, Classic Maya state]     

3800 Years of Quantitative Precipitation Reconstruction from the Northwest Yucatan Peninsula

Precipitation over the last 3800 years has been reconstructed using modern pollen calibration and precipitation data. A transfer function was then performed via the linear method of partial least squares. By calculating precipitation anomalies, it is estimated that precipitation deficits were greater than surpluses, reaching 21% and <9%, respectively. The period from 50 BC to 800 AD was the driest of the record. The drought related to the abandonment of the Maya Preclassic period featured a 21% reduction in precipitation, while the drought of the Maya collapse (800 to 860 AD) featured a reduction of 18%. The Medieval Climatic Anomaly was a period of positive phases (3.8–7.6%). The Little Ice Age was a period of climatic variability, with reductions in precipitation but without deficits.     

Status and Power in Classic Maya Society: An Archeological Study

This article uses archeological data to examine how social relations allocate economic and political power in ancient complex societies. Based on recent excavations in the Copan Valley, Honduras, the socioeconomic organization of the basic residential group is reconstructed and the existence of a pervasive social hierarchy demonstrated. I argue that during the Late and Terminal Classic periods, the Maya were organized into a series of internally ranked and externally stratified status lineages (Goldman 1970) that structured social, economic, and political relationships.     

Like Water for Chocolate: Feasting and Political Ritual among the Late Classic Maya at Xunantunich, Belize

Subtle differences in the context of feasting and manners of food consumption can point to underlying levels of civil and social competition in state-level societies. Haute cuisine and high styles of dining are characteristic of societies with fully developed civil and social hierarchies such as Renaissance Europe and the Postclassic Aztec. Competitive yet socially circumscribed political and social organizations such as the Classic lowland Maya may have prepared elaborate diacritical meals that marked status, but the nature of feasting remained essentially patriarchal. Ancient Maya feasting is recognizable through archaeologically discernible pottery vessel forms that were used to serve festival fare such as tamales and chocolate. Comparison of ceramic assemblages across civic and household contexts at the site of Xunantunich, Belize, demonstrates that drinking chocolate, more so than eating tamales, served as a symbolic cue that established the political significance of events among the Classic Maya.

Detection of significant demographic differences between subpopulations of prehispanic Maya from Copan, Honduras, by survival analysis

Heterogeneity and small sample size are problems that affect many paleodemographic studies. The former can cause the overall distribution of age at death to be an amalgam that does not accurately reflect the distributions of any of the groups composing the heterogeneous population. The latter can make it difficult to separate significant from nonsignificant demographic differences between groups. Survival analysis, a methodology that involves the survival distribution function and various regression models, can be applied to distributions of age at death in order to reveal statistically significant demographic differences and to control for heterogeneity. Survival analysis was used on demographic data from a heterogeneous sample of skeletons of low status Maya who lived in and around Copan, Honduras, between A.D. 400 and 1200. Results contribute to understanding the collapse of Classic Maya civilization.     

Assessing the impact of ancient Maya animal use

Tropical forest animals are at high risk worldwide as a result of over-exploitation and forest clearing. Zooarchaeological studies of animal use by the ancient Maya of the southern lowland regions of Guatemala, Honduras, Belize, and Mexico provide long-term historical information on animal populations under conditions of human population growth and climatic change that is valuable to both archaeology and conservation biology. In this paper, zooarchaeological data from 35 chronologically defined faunal sub-samples recovered from 25 ancient Maya archaeological sites are used to assess the effects of ancient hunting on animal populations of the Maya region between the Preclassic and Colonial periods (2000 BC–AD 1697). The variations in species abundance are used as a proxy for describing changes in ancient Maya hunting practices and hunted animal populations, interpreted on the basis of hunting efficiency models from foraging ecology. A significant reduction in the proportion of large mammals, particularly Odocoileus virginianus, in zooarchaeological assemblages between the Late Classic (AD 600–850) and Terminal Classic/Postclassic periods (AD 850–1519) suggest that over-hunting during the Late Classic may have led to a reduction in availability of these animals to the ancient Maya hunters in the later periods. This finding is discussed in relation to important social and environmental variations to evaluate the impact of hunting and other factors such as forest clearance and climate on ancient animal populations in the Maya region.     

Porotic Hyperostosis and Paleoepidemiology: A Forensic Perspective on Anemia among the Ancient Maya

Porotic lesions caused by childhood anemia are commonly found on ancient Maya crania and have been cited as evidence for extremely poor nutrition during the Classic Period. We reconsider this characterization in the light of recent data on childhood anemia in rural Guatemala and the prevalence of porotic hyperostosis in crania of forensic skeletal remains of rural highland Maya from Plan de Sanchez, Baja Verapaz, which date to 1982. The abundance of porotic hyperostosis in adults from Plan de Sanchez fits well with the number of modern rural children suffering from anemia, but the lesions are very rare compared to archaeological series. Although some minor change in diet and infection may contribute to differences in porotic hyperostosis, it is likely that higher mortality leads to fewer anemic lesions in modern adult crania. We hypothesize that more anemic children survived to adulthood in the past than do today, [iron-deficiency anemia, porotic hyperostosis, Maya, nutrition, forensic anthropology, osteological paradox]     

Delineating genetic relationships among the Maya

By 250 AD, the Classic Maya had become the most advanced civilization within the New World, possessing the only well-developed hieroglyphic writing system of the time and an advanced knowledge of mathematics, astronomy and architecture. Though only ruins of the empire remain, 7.5 million Mayan descendants still occupy areas of Mexico, Guatemala, Belize, El Salvador, and Honduras. Although they inhabit distant and distinct territories, speak more than 28 languages, and have been historically divided by warfare and a city-state-like political system, and they share characteristics such as rituals, artistic, architectural motifs that distinguish them as unequivocally Maya. This study was undertaken to determine whether these similarities among Mayan communities mirror genetic affinities or are merely a reflection of their common culture. Four Mayan populations were investigated (i.e., the K'iche and Kakchikel from Guatemala and the Campeche and Yucatan from Mexico) and compared with previously published populations across 15 autosomal STR loci. As a whole, the Maya emerge as a distinct group within Mesoamerica, indicating that they are more similar to each other than to other Mesoamerican groups. The data suggest that although geographic and political boundaries existed among Mayan communities, genetic exchanges between the different Mayan groups have occurred, supporting theories of extensive trading throughout the empire.     

Intertooth patterns of hypoplasia expression: Implications for childhood health in the Classic Maya collapse

Enamel hypoplasias, which record interacting stresses of nutrition and illness during the period of tooth formation, are a key tool in the study of childhood health in prehistory. But interpretation of the age of peak morbidity is complicated by differences in susceptibility to stress both between tooth positions and within a single tooth. Here, hypoplasias are used to evaluate the prevailing ecological model for the collapse of Classic Period Lowland Maya civilization, circa AD 900. Hypoplasias were recorded in the full dentition of 160 adult skeletons from six archaeological sites in the Pasión River region of Guatemala. Instead of constructing a composite scale of stress experience, teeth are considered separately by position in the analysis. No statistical differences are found in the proportion of teeth affected by hypoplasia between “Early,” Late Classic, and Terminal Classic Periods for anterior teeth considered to be most susceptible to stress, indicating stability in the overall stress loads affecting children of the three chronological periods. However, hypoplasia trends in posterior teeth may imply a change in the ontogenetic timing of more severe stress episodes during the final occupation and perhaps herald a shift in child-care practices. These results provide little support for the ecological model of collapse but do call to attention the potential of posterior teeth to reveal subtle changes in childhood morbidity when considered individually.

Carious lesions and maize consumption among the Prehispanic Maya: an analysis of a coastal community in northern Yucatan

Patterns of carious lesions were analyzed in the Classic period coastal Maya population of Xcambó, a salt production and administration center in northern Yucatan. To this end, the study investigated caries in the permanent dentitions of 163 adult skeletons, 23 from the Early Classic (AD 250-550) and 140 from the Late Classic period (AD 550-750), equally distributed between sexes. The archaeological and bioarchaeological evidence indicates a wealthy and socially homogeneous population dedicated to salt production and administration in the Early Classic that switched to pure administrative functions in the Late Classic. The results indicate an increase in caries from 7.4% and 21.2% (males and females respectively) from the Early Classic to 14.0% in males and 27.4% in females from the Late Classic period. The rate of caries in the Early and in the Late Classic phases of continuous occupation is not consistent with a simple interpretation of a heavier reliance on maize during the latter phase, characterized by a sedentary lifestyle, particularly for the male segment of the society now dedicated completely to the administration of the salt mines. Rather, the increase in caries rates in both sexes is best explained within a broader context of overall food habits, new cariogenic foods for both sexes, and the changes in lifestyle imposed by the increased socioeconomic role of the site. Our conclusions stress the limitations imposed by interpreting carious lesions solely in terms of single dietary components, such as maize consumption, without taking into account broader aspects of cultural and socioeconomic relevance.
