This article analyzes the assemblages of humans and other-than-humans that animated the sacred landscape of Cerro de la Virgen, a hilltop site occupied during the Formative period (1800 BC–AD 250) in the lower Río Verde Valley of coastal Oaxaca, Mexico. Commensalism in the region increased markedly in scope and complexity throughout the Formative period, culminating in the region's first polity at AD 100. Feasting practices became relatively standardized, but the placement of objects and bodies in public architecture—a set of collective practices associated with the vital forces that animated the cosmos—varied considerably from site to site during the late Terminal Formative period (150 BC–AD 250). Lower Verde scholars have argued that these idiosyncrasies reflect the myriad collective identities of the region's hinterland communities, a pattern rooted in local affiliations that may have conflicted with an expanding regional identity centered at the urban center of Río Viejo. I augment this discussion by highlighting the role that the materiality of the landscape, present before humans even occupied the region, played in the construction of collective identity. I develop an interpretive approach that pays special attention to Indigenous concepts of ontology, particularly those related to animacy and its transference, and uses the semiosis of American philosopher Charles Peirce to elucidate meaning from deposits of cached objects. The animate qualities assembled through fired clay and chiseled stone at Cerro de la Virgen afforded a ritual pattern that was unique in coastal Oaxaca at the end of the Formative period.

This report examines the deposit of a sixteenth-century cache of silver aquillas within a Chachapoya household at the site of Purun Llacta de Soloco. The report examines their context and contents. These findings have implications for a larger examination of social value in Andean societies and the specialized treatment and use of ritual objects during the tumultuous colonial period.

This article examines Middle and Late Preclassic period ritual activity and caches discovered in the Central E Group complex at the ancient Maya site of Cival, which is located in northeastern Peten, Guatemala. It focuses on a series of excavations conducted in 2013 and 2014 at Structure 9, the E Group's western radial pyramid and uses theories of social memory and sacred place to provide insight into the recently discovered caches, termination rituals, and the deliberate destruction of architectural features found there. It also draws on previous ritual activity conducted in the Central E Group plaza and the site's broader history to obtain a more comprehensive understanding of the role of this complex as a sacred place and hub of memory at Cival for more than 1,000 years.

Even though lithics in the Maya region have traditionally been relegated to appendices and tool-type lists, much has been done to move beyond this descriptive approach in the last decade. In this article we highlight general themes of lithic studies in the Maya region since 2011, including economic production and exchange, the role of lithics in ritual practice, and the use of previously understudied raw materials and lithic forms, such as ground stone. Employing a temporal scope that encompasses the Maya and their preceramic predecessors, we explore gendered patterns of research within lithic studies from a feminist perspective and discuss the impacts that gender disparities have on academic thought.

Biophysical conditions played a fundamental role in early human colonization of insular territories, particularly in food-producing societies dealing with limited resources and the challenges of maintaining a sustainable carrying capacity. Studies on past human colonization of small oceanic islands thus offer insights into economic plasticity, ecological impacts, and adaptation of early food-producing groups. On the coast of southern Chile, early evidence is dated to 950 cal BP of island colonization by coastal populations with mainland subsistence systems based on the exploitation of marine resources, along with gathering, managing, and cultivating plants and hunting terrestrial animals. Strikingly, the extent to which these mixed economies contributed to insular colonization efforts is largely unknown. Here we used organic residue analysis of ceramic artifacts to shed light on the subsistence of populations on Mocha Island in southern Chile. We extracted and analyzed lipids from 51 pottery sherds associated with the El Vergel cultural complex that flourished in southern Chile between 950 and 400 cal BP. Chemical and stable isotope analysis of the extracts identified a range of food products, including C3 and C4 plants and marine organisms. The results reveal the central role of mixed subsistence systems in fueling the colonization of Mocha Island.

During the Middle Horizon (AD 600–1000), obsidian was transported in greater quantities and distances than ever before identified in the Andes, in part by the expansionary Wari state. Two of the three major obsidian sources used in the south-central Andes are located in the modern department of Arequipa, Peru. Arequipa was a region of intense Wari influence and intrusive presence; however, little is known about regional obsidian use. Portable X-ray fluorescence (pXRF) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) were used to analyze 383 obsidian artifacts recovered from 10 archaeological sites in Arequipa. Results highlight diachronic and spatial patterning related to obsidian procurement strategies, state versus bottom-up exchange networks, and local participation within the Wari realm. A wide variety of geological obsidian sources, including nonlocal obsidians originating from Wari's Ayacucho heartland, were used. By the late Middle Horizon, the Wari had consolidated regional resources with the sole use of Alca-1 and Alca-4 bedrock obsidians, the largest-sized and highest-quality sources in the area. We assess related models of obsidian procurement and exchange related to state political economy, long-distance caravan activity, and the role of local ceremonial/waystation centers that facilitated the flow of ideas, goods, and people across Arequipa.

Archaeological research on the architecture and sculpture of Tiwanaku society in the south-central Andes follows two separate paths: one emphasizes iconographic interpretation, whereas the other studies lithic materials’ origin and spatial relations. This separation, stemming from dualistic modern thought, is an obstacle to a comprehensive understanding of lithic sculptures and their role in Tiwanaku society. This article focuses on the Ponce and Bennett monoliths, the two largest and most complex sculptures of the Tiwanaku ceremonial center. It presents the results of an iconographic analysis identifying minimal design components ordered in a three-level nested hierarchy and their distribution over the spatial structures of both sculptures. This analysis incorporates existing information about lithic materials and quarries, the monoliths’ locations, and spatial relationships. All those data are interpreted in the light of Aymara and Quechua ontologies about the relationships between mountains, stones, and images. Characterizing aspects of the Tiwanaku site and its role in lithic production, this article extends the limits of Tiwanaku society to include nonhuman agents and suggests that we overcome anthropocentric biases.

We previously reported astronomical alignments with the principal temple of the archaeological site of El Paraiso in coastal Peru. Here we describe a new investigation of nine small platform mounds associated with the two giant animal effigy mounds at the site. A total station map of the site permits possible astronomical alignments to be measured directly from the AutoCAD map by Pixelstick or AutoCAD. We corrected alignments for obliquity and for the apparent curvature of the sun and moon over the crest of nearby ridges. Azimuths for astronomical events were obtained from Starry Night Pro Plus 6.4.3. We found that 13 of 14 alignments were within 1° of the predicted astronomical values (and all 14 were within 1.5°). To account for these findings and those of the giant animal platform effigy mounds at the site, we propose a cosmology in the Late Preceramic period of solar and lunar alignments and the linkage of supernatural animals to dark cloud constellations. The building of these mounds was directed by astronomer priests. A shared belief in a cosmology that included a punishing force may have eased transactions by engendering trust among individuals living across river valleys and at different altitudes.

The Tiwanaku civilization (around AD 500–1100) originated in the Bolivian altiplano of the south-central Andes and established agrarian colonies (AD 600–1100) in the Peruvian coastal valleys. Current dietary investigations at Tiwanaku colonial sites focus on maize, a coastal valley cultivar with ritual and political significance. Here, we examine Tiwanaku provincial foodways and ask to what degree the Tiwanaku settlers maintained their culinary and agrarian traditions as they migrated into the lower-altitude coastal valleys to farm the land. We analyze archaeobotanical remains from the Tiwanaku site of Cerro San Antonio (600 m asl) in the Locumba Valley and compare them to data from the Tiwanaku site in the altiplano and the Rio Muerto site in the Moquegua Valley during the period of state expansion. Our findings show high proportions of wild, weedy, and domesticated Amaranthaceae cultivars, suggesting that Tiwanaku colonists grew traditional high-valley (2,000–3,000 m asl) and altiplano (3,000–4,000 m asl) foods on the lowland frontier because of their established cultural dietary preferences and Amaranthaceae's ability to adapt to various agroclimatic and edaphic conditions.

We examined stable isotopes (δ13C, δ15N, and δ34S) of camelid, cavid, and cervid remains from Upanca, an archaeological site located in the Southern Nasca Region on the south coast of Peru. Occupation at the site began in the Middle Archaic (around 3200–3000 BC) and continued through the Nasca period (AD 100–650). Remains predating 2500 BC show low δ13C and δ15N values, whereas remains after this time show increasing and especially more variable isotopic values. We interpret this pattern as marking both a process of agricultural intensification and camelid husbandry diversification. Agricultural intensification began first with C3 plants in fertilized fields, beginning around 2200 cal BC, followed by an increasing use of C4 plants (maize, kiwicha, or both), particularly after 800 cal BC. By the beginning of the first millennium, people were using a diverse range of strategies to raise llamas and alpacas, including feeding them wild or cultivated C3 plants, feeding them cultivated C4 plant foods, mixing C3 and C4 plant foods, foddering some in natural coastal environments, and acquiring still other camelids by hunting wild stocks (guanaco, vicuña). Data also suggest that cavids were consuming at least some C4 products after 1000 cal BC and that the use of C4 plants increased over time.

The nineteenth century was a dynamic period for hacienda workers on the south coast of Peru. Former Jesuit vineyards with two of the largest enslaved African-descended populations in rural coastal Peru—the haciendas of San Joseph (San José) and San Francisco Xavier (San Javier)—and their annexes in Nasca's Ingenio Valley underwent dramatic transformations with the replacement of their grapevines with cotton and the introduction of new types of workers. Cantonese indentured workers were contracted beginning in the 1830s, and the majority-enslaved workforce was legally emancipated in 1854. Seasonally, highland Andean workers joined the demographically shifting permanent hacienda population. We use evidence from excavated midden contexts at San Joseph, San Xavier, and San Joseph's annex of Hacienda La Ventilla to explore these changing agroindustrial dynamics and worker well-being in the eighteenth and nineteenth centuries. Despite the transformations at the estates, we find that culinary practices developed by enslaved Africans and their descendants during the Jesuit administration, such as the preparation of one-pot meals and stews, continued into the republican era among Cantonese indentured laborers and wage workers of Indigenous, mestizo, and Cantonese origins. We argue that such strategies centered on foodways were a crucial aspect of worker self-care regimes and broader well-being.

Coccidioidomycosis is an infectious fungal disease endemic in Bolivia's Gran Chaco region that is caused by inspiration of the spores of Coccidiodes species. It is a respiratory pathology that can spread to the skeleton and produce diffuse lytic lesions in different parts of the body. This disease has rarely been described in historic populations, and we present here a new case of coccidioidomycosis in a mummified human individual. It corresponds to a female individual with an age at death of 25–35 years, dated to the Tiwanaku epoch of the thirteenth century AD. It was found inside a sepulchral cave near the city of Ulloma in western Bolivia. Radiographic examination shows numerous osseous lytic lesions with central cavitation concentrated on the cranial table and vertebral bodies. The observed condition could correspond to the secondary phase of coccidioidomycosis. This diagnosis is noteworthy because coccidioidomycosis was mainly described as a male work-related disease and has never been found in ancient western Bolivia.

Este artículo analiza la arquitectura del período Clásico de Pahñú, un centro ceremonial en el noreste del valle del Mezquital, México. Esta arquitectura se distingue porque desarrolló un estilo local, integrando elementos de distintas tradiciones culturales. Por un lado, los conjuntos arquitectónicos de patio hundido siguen los estándares de la tradición del Bajío. Por otra parte, los edificios muestran rasgos de la arquitectura monumental teotihuacana y zapoteca. A partir de esta evidencia se concluye que Pahñú definió su identidad étnica estableciendo filiaciones políticas con las culturas del centro y el Bajío. Esta interpretación pone a prueba varias explicaciones previas que conciben el desarrollo regional durante el período Clásico como aculturación o resistencia a Teotihuacán. Asimismo, pone a prueba las interpretaciones que sostienen que la fusión cultural entre los grupos del centro y el Bajío comenzó hasta el Epiclásico. Finalmente, Pahñú es importante porque representa un pequeño centro político que mantuvo su liderazgo por unos seiscientos años, aprovechando su posición fronteriza entre el centro y el Bajío.

We present macrobotanical, starch, and phytolith data from artifacts and sediments from Middle Formative La Blanca (1000–600 cal BC) and Late Formative El Ujuxte (600 cal BC–cal AD 115 ) in the Soconusco region in Guatemala. Potential economic plants identified included palm (cf. Arecaceae), two varieties of maize (Zea mays), guava (Psidium guajava), bean (Phaseolus), chili peppers (Capsicum), squash (Cucurbitaceae), custard apple (Annonaceae), coco plum (Chrysobalanaceae), lerén (Calathea), arrowroot (Maranta), and bird-of-paradise (Heliconia). The results suggest that control of food production and consumption was critical for the transition from complex chiefdoms during the Middle Formative to the archaic state in the Late Formative. The arrival of a more productive South American variety of maize at El Ujuxte (about 2549 BP) allowed elites to exploit an already existing broad-based economic system and to use the maize-based religious system to increase control over maize agricultural practices and maintain power through ideology and disciplinary power. These data suggest that the arrival of fully domesticated South American maize likely influenced the overall development of Mesoamerican state-level societies.

Complex human–environmental processes form identifiable, lasting features on the landscape that can illuminate past human behavior and human–environment interactions. We examine the anthropogenic landscape of the ancient port of Macurany, located along the middle Amazon River in Parintins, Brazil, and identify four classes of anthropogenic landscape features at the site: wharfs, middens, terra preta (dark or black earths), and cultural forests. Middens, terra preta, and cultural forests have been found at archaeological sites in regions surrounding Macurany, but wharfs have not previously been reported in Amazonian contexts predating European contact. Taken together, these features are clearly the result of anthropogenesis and represent a range of subsistence, settlement, and infrastructure-building activities pointing to an ancient society that was actively engaged in modifying the surrounding landscape for purposes beyond settlement and subsistence. Evidence for a permanent, extensive, continuously settled society practicing intensive landscape engineering in this region of Amazonia reinforces findings of dense habitation, infrastructure, and early urbanization in Amazonia prior to European contact. This research helps expand our understanding of human–environment interactions, landscape formation processes, and settlement organization in ancient Amazonia.

This article charts the collection history of the only surviving precolumbian cotton reliquary (cemí) from the Dominican Republic, establishing its provenance from the mid-nineteenth century through a previously unpublished manuscript written by the collector, Rodolfo Domingo Cambiaso Sosa, and using archival documents in Italy. The cemí, found in a cave in the southwest of the country near the town of Petitrou (Enriquillo), was purchased in 1882 by Admiral Giuseppe Giovanni Battista Cambiaso, one of the founders of the Dominican Navy. It emerged in international publications commemorating the quadricentennial of the Spanish–Indigenous encounter in 1892 and shortly thereafter was sent to Genoa, Italy. It entered the collections of Turin's Royal Museum of Antiquities in 1928 before being passed to the newly established Museum of Anthropology and Ethnography. It was rediscovered by Dominican scholars in the 1970s and has inspired numerous investigations since, including renewed collaborative links between the Dominican Republic and Italy.

Settlement scaling theory predicts that higher site densities lead to increased social interactions that, in turn, boost productivity. The scaling relationship between population and land area holds for several ancient societies, but as demonstrated by the sample of 48 sites in this study, it does not hold for the Northern Maya Lowlands. Removing smaller sites from the sample brings the results closer to scaling expectations. We argue that applications of scaling theory benefit by considering social interaction as a product not only of proximity but also of daily life and spatial layouts.

The Napo River basin, which is situated within the Upper Amazon archaeological region, is one of the most speciose forests in Greater Amazonia. Standard thinking in scholarship and science holds that these forests are essentially pristine because any Indigenous impacts in the past would have been minimal, seedbanks would have been nearby, and natural forests would have reappeared after the humans left, died out, or dispersed. Inventory research in 2019 on three ridgetop forests in Waorani territory inside the Curaray basin (which drains to the right margin of the Napo River) and a comparable inventory on one control site forest along the Nushiño River (also in the Curaray basin) show human impacts from about the late nineteenth century to about 1960; they occurred during the period of wartime among Waorani themselves and between Wao people and outsiders. The human impacts resulted in the high basal-area presence of two long-lived species with important Waorani cultural uses: cacao (Theobroma cacao L.) and ungurahua palm (Oenocarpus bataua Mart.). These species have high frequency and dominance values and do not occur in the control site, which is comparable in terms of elevation above the flood zone of the rivers in the sample. These findings mean that alpha diversity in the right margin sector (or south) of the Napo River basin cannot a priori be explained by reference to traditionally, biologically accepted patterns of ecological succession but may require knowledge of historical patterns of Indigenous land use and secondary landscape transformation over time due to human (specifically Waorani) impacts of the past.

This article reports the material evidence of roads in the northwestern Maya Lowlands that were in use from the Middle Preclassic (800–300 BC) through the Late Classic (AD 700–900) period in Chiapas and Tabasco, Mexico. The study includes archaeological evidence recovered from field research in an area covering approximately 670 km2 and 618 recorded archaeological sites. It presents the physical characteristics of a series of piedmont paths that connected the region from the Usumacinta River to the Tulijá River, including large population centers such as Palenque and Chinikihá. The study uses a geographic information system (GIS) least cost path (LCP) analysis to identify the location of roads and how they relate to regional settlement patterns. It also tests the use of modern computational models to advance regional studies in the Maya area. Study results show how the Classic Maya adapted and appropriated the region's topography to facilitate movement, long-term settlement, and the building of landesque capital.
