The first direct evidence of pre-columbian sources of palygorskite for Maya Blue

Maya Blue, a nano-structured clay–organic complex of palygorskite and indigo, was used predominantly before the Spanish Conquest. It has fascinated chemists, material scientists, archaeologists and art historians for decades because it is resistant to the effect of acids, alkalis, and other reagents, and its rich color has persisted for centuries in the harsh tropical climate of southern Mesoamerica. One of its components, palygorskite, is part of modern Maya indigenous knowledge, and ethnohistoric and archaeological data suggest that its modern sources were probably utilized in Prehispanic times. Yet no direct evidence verifies that palygorskite was actually mined from these sources to make Maya Blue. Here we characterize these sources compositionally, and compare our analyses to those of Maya Blue from Chichén Itzá and Palenque. We demonstrate that the palygorskite in most of these samples came from modern mines, providing the first direct evidence for the use of these sources for making Maya Blue. These findings reveal that modern Maya indigenous knowledge about palygorskite, its mining, and its source locations, is at least seven centuries old.     

Where is Lowland Maya archaeology headed?

This article isolates three important trends in Lowland Maya archaeology during the last decade: (1) increased use of the conjunctive approach, with renewed appreciation of context and provenience; (2) waning use of the label unique to describe the Maya; and (3) an effort to use the Lowland Maya as a case study in social evolution.     

‘The first duties of persons living in a civilized community’: the Maya, the Church, and the colonial state in southern Belize

In recent years, historical geography has been at the forefront of new scholarship on the spatiality of colonial power and its complex relations with indigenous communities. This literature shows that imperial policies – emerging through state and scientific institutions, cultural practices, and capitalist ventures – required particular ways of conceptualizing, mapping, and organizing spaces and territories which transformed the geographies of indigenous communities, livelihoods, and identities. Through a close reading of archival texts from the late 19th and early 20th century, this paper examines the spatial and political relations between three groups: the Catholic Church, the British colonial state, and the Maya communities of southern British Honduras. Differences between the Catholic Church and the British colonial state – in their aims and approach to winning hegemony over the Q'eqchi' and Mopan Maya – were accommodated and assuaged by a tacit agreement: that the Maya must be settled in permanent communities. Colonial power, in both its spiritual and statist modalities, was imminently geographical, and this geography comprised the common ground between Church and state in their approach to the Maya.     

Postclassic Maya slips and paints and their relationship to socio-political groups in El Petén,Guatemala

LA-ICP-MS analysis of the chemical composition of the exterior slips and red and black pigments used for painted decoration of the three Postclassic Maya slipped ceramic wares suggests that the Itzá and Kowoj used different pigments for exterior slips and decorative motifs. Additionally, different slips and paints were used depending on vessel form and decorative program (red, black, or red-and-black painting or incising). When examined with previous ceramic paste chemical analyses, the data aid in better understanding the changing socio-political alliances and dominance relations in central Petén at the eve of Spanish contact.     

The children of Kaminaljuyu: Isotopic insight into diet and long distance interaction in Mesoamerica

Known for its spectacular tombs and adobe talud–tablero architecture, the highland Guatemalan city of Kaminaljuyu is key to models of long distance interaction in Mesoamerica. We use stable isotopic data from human bone, dentine and tooth enamel to reconstruct Kaminaljuyu’s dietary history. Stable carbon isotope ratios and alkaline earth ratios of enamel carbonate indicate a decline in maize consumption from Preclassic to Classic periods, perhaps due to the desiccation of Lake Miraflores, which was used to irrigate Late Preclassic fields. Stable oxygen and strontium isotope ratios in enamel shed light on the geographic origin of Early Classic skeletons, and show that the central skeletons in the tombs were local children. However, four decapitated skulls and two peripheral skeletons show enriched oxygen ratios, similar to Lowland Maya sites. Strontium isotope ratios indicate that most of these are from an area underlain by Cretaceous limestones; one is from a metamorphic region. Two individuals may have traveled to or from Central Mexico. The greater evidence for lowland individuals among the tomb skeletons implies that political connections with the Maya area were more significant to elites at Kaminaljuyu than was direct contact with Central Mexico.     

Cluster analysis of mixed-level data: Pottery provenience as an example

Provenience or “sourcing” studies of archaeological objects most commonly employ quantitative measurements of amounts of chemical constituents in the artifacts and source materials. These are then used in statistical grouping procedures known as cluster analyses. Many additional attributes of artifacts and sources, yielding lower-level qualitative data, are also of potential importance in determinations of artifact origins. These attributes are usually neglected because of the longstanding difficulty in treating “mixed-level” data, that is, combining both qualitative observations and quantitative information in a single powerful statistical procedure. A series of cluster analyses were run on two data sets consisting of archaeological pottery, using mixed-level characterization data in the CLUSTAN program with Gower's coefficient of similarity. The clustering solutions are interpretable in terms of provenience and production strategies.     

Contact and Missionization at Tayasal,Petén,Guatemala

Abstract

Until their conquest by the Spanish in 1697, many Itza Maya occupied a large village at Tayasal, Petén, Guatemala. After the conquest, two missions were built there. The village and missions are located within 2 km of modern Flores, which was once Nojpetén, the Itza capital, and later the Spanish presidio (fortified administrative center). Our excavations uncovered the San Bernabé mission on the Tayasal peninsula and defined the Late Postclassic-period (a.d. 1400–1525) occupation of the site. San Bernabé was established in the early 18th century as part of Spanish efforts to control indigenous populations in Petén. Our research demonstrates that the Late Postclassic settlement was larger than indicated by previous research and supported a relatively large ceremonial architectural group. Evidence of indigenous practices was recovered from deposits within the mission, though many elements of Itza religion found in the Late Postclassic group were absent from the mission settlement. These data provide additional evidence of religious syncretism in colonial situations.
