A hallmark of ancient Mesoamerican art and religion is the ability of ritual practitioners, sometimes called “shamans,” to transform. The Olmec were-jaguar is a well-known example of the phenomenon. Artifacts from different regions demonstrate that these beliefs involved many animal and spiritual entities and a porous boundary between humans and other beings. In this article, we examine the archaeology of ritual transformation in Preclassic or Formative period (2000 BC–AD 250) Oaxaca, Mexico. As links between the physical world and other dimensions, altered bodies reflect negotiated relationships among people, animals, ancestors, deities, and landforms. Traditional interpretations of transformational art have oversimplified the role of nonhumans in these processes by representing ritual practitioners as “impersonating” other beings; for example, by wearing masks. We draw on almost two centuries of archaeology, Indigenous history, and ethnography to demonstrate that the reification of separate cultural and natural worlds is a modern artifice that would be unrecognizable to ancient Oaxacans. It was via transformation that ancient Mesoamerican people intimately knew their world, engaged the senses, and acquired knowledge.

Emotions are a vital part of coalescent communities. Specifically, they help create the broader relational fields in which coalescent communities form; they also dictate the practices and sentiments of community members as well as the impacts of these communities on the wider world. This article examines the “affective fields” that created Noble-Wieting, a late thirteenth-century Langford-Mississippian village in what is now central Illinois. Due to population movements, social unrest, and climate change during the thirteenth through fifteenth centuries in the North American Midwest, feelings of unease and anxiety colored the larger relational and affective fields in which Noble-Wieting was constructed and were the driving force behind the construction of coalescent communities like Noble-Wieting. Archaeological evidence from an ongoing consultative and collaborative project at Noble-Wieting shows that the layout of the village and the activities that occurred there facilitated community integration and thus mitigated residents’ anxiety, at least to some degree. This study shows that the physical layout and materiality of communities are crucial in altering residents’ experiences and emotions.

This article examines the functions and meanings of akropoleis in Greek antiquity, drawing on references from ancient textual sources from Homer until the second century AD. Despite its rarity in literature and epigraphy, the word ‘akropolis’ carried a wide array of often conflicting connotations throughout antiquity. This study highlights how the symbolic meaning of ‘akropolis’, in parallel with historical developments, developed from an overall marker of civic pride in Classical-period texts to a metaphor of oppressive rule in later literature. While acknowledging local and temporal variation, the study argues for a careful, historically grounded application of the term in scholarship. Ultimately, akropoleis emerge not only as architectural features but as potent cultural signifiers with enduring resonance in the political and philosophical imagination of antiquity.

Oil contamination in estuarine and coastal ecosystems presents major challenges for environmental monitoring due to the complex mixture of organic matter from biogenic and petrogenic sources. This review synthesizes recent advances and limitations in the combined use of carbon isotopes δ13C and Δ14C to trace petroleum contamination in marine sediments. Sixteen empirical studies were analyzed to evaluate the effectiveness of this dual-isotope approach in identifying fossil carbon, estimating its degradation state, and assessing its environmental persistence. While δ13C provides insights into organic matter sources and transformation, Δ14C offers a sensitive tracer for detecting fossil carbon inputs, even in low concentrations or mixed matrices. The review highlights how their integration strengthens source attribution and enhances the resolution of hydrocarbon monitoring in dynamic coastal settings. An exploratory typology based on Δ14C and Fm is proposed to semi-quantitatively classify contamination severity and support cross-study comparisons. Despite its potential, the approach faces challenges such as high analytical costs, limited laboratory access, and a lack of methodological standardization. Future efforts should focus on integrating compound-specific isotope analysis, expanding applications in mangrove ecosystems, and refining interpretative models to improve the forensic utility of carbon isotopes in oil spill investigations. This review contributes to the systematization of isotopic methods in environmental forensics and reinforces their role in tracing petroleum-derived carbon in sensitive coastal environments.

This paper presents 56 AMS radiocarbon dates from three early medieval sites in Italy: nine from the Roman Villa of Vacone in Vacone (RI), Lazio, 29 from the Roman Villa of Selvicciola in Ischia di Castro (VT), Lazio, and 18 from the necropolis of Povegliano Veronese (VR), Veneto. These results more than double the number of previously published radiocarbon dates from early medieval Italy and are therefore a substantial contribution to the absolute chronology of early medieval cemeteries of Italy. These dates have implications for the relative dating of grave goods, grave reuse, and explaining the presence of graves with multiple individuals.

Coastal, riverine, and lacustrine environments have played a central role in the development of human societies, yet locating and documenting this record of activity in littoral environments have proven difficult. Terrestrial survey methods reach their limit at the water’s edge, whereas marine geophysical equipment often struggles in depths of less than 1 m. This “white ribbon” of missing data represents a persistent methodological gap but one that is rich in information. Recent work on Scottish crannogs, or artificial islands, has highlighted this predicament while also providing a test bed for practical solutions. This article presents the results of that work: a robust and repeatable workflow for high-resolution shallow-water photogrammetry, tested in challenging conditions and benchmarked against the GNSS-enabled accuracy of drone surveys. The approach combines stereophotogrammetry, using artificial scale bars for internal calibration, with ground control points to enable the integration of terrestrial and underwater data. This method is both accessible and efficient, offering a replicable framework for recording archaeological sites at the water’s edge.

In this paper, we reconsider the relationship between continuity and change in archaeology by arguing that material continuities do not necessarily imply conservatism or resistance to change but function as precondition for transformation. Drawing on Deleuze and Guattari’s notion of thought as a ‘play of forms’, we conceptualize architecture as an active medium of sense-making, through which societies reframe novelty within familiar epistemic traditions. We examine two case studies: proliferation of compound coresidential enclosures (CCE) in the Central Andes and adoption of the vihara in Angkorian Cambodia. Though often interpreted as ruptures or external impositions, both forms drew upon existing religious and political traditions, making new social projects legible. Over time, these architectures reorganized social relations and became central to emerging formations: Andean ayllus and Khmer Theravada Buddhism. By reframing continuity as a resource for sense-making rather than conservatism, we argue that transformation emerges through creative reworking of tradition, situating thought-in-action at the core of historical change.
