Recent research conducted in northern Michoacan, west Mexico, has yielded significant new datasets that can be used to reconsider the occupation of this region in the Postclassic period (a.d. 900–1541), prior to and during the rise of the Tarascan state. LiDAR data, in particular, has facilitated reassessment of the archaeological record and its implications concerning the population and social dynamics of this region. In this article, I combine data collected through traditional field-based research with LiDAR-derived data to reassess the population aggregation that occurred during a.d. 1250–1450 in the Zacapu Basin, resulting in the formation of a large urban system. Compared to prior population estimates and interpretations regarding the urban structure of the Zacapu Malpaís sites, the integration of these datasets enables both an increased scale of analysis and finer resolution, thus providing a clearer picture of one of the earliest episodes of urbanization in west Mexico.

En el siglo dieciséis, la conquista española se extendió rápidamente hacia lo que hoy se conoce como el occidente de México. A partir de 1522, el reino tarasco sucumbió frente a los españoles y con ello iniciaron su proyecto de colonización y expansión territorial. Desde las primeras décadas, los españoles moldearon las actividades cotidianas para asegurar el control sobre las poblaciones indígenas, incluyendo la evangelización y promoviendo la explotación económica de los nuevos territorios.

Uno de los primeros pasos fue reorganizar el patrón de asentamiento de las poblaciones tarascas. En vísperas de la Conquista, los tarascos habitaban en pequeñas aldeas situadas en las cumbres y laderas de las montañas. Los españoles modificaron el patrón de asentamiento a través de dos medidas principales: en primer lugar, el desplazamiento de los antiguos asentamientos (pueblos viejos) a los valles o llanuras cercanas, con el fin de evitar que los sitios se convirtieran en fortalezas; en segundo lugar, los españoles reagruparon a la población en centros más grandes, conocidos como congregaciones.

Más allá de la distribución espacial de los lugares, esta transformación afectó por completo la configuración del espacio y repercutió en la relación existente entre los pobladores y el paisaje y con ello en la geografía sagrada. A partir del ejemplo de la localización de dos pueblos en el norte del estado de Michoacán—el sitio prehispánico Mich. 68-El Caracol y el pueblo colonial Mich. 415-Las Iglesias, descubiertos gracias a la obtención de imágenes LiDAR del Proyecto Arqueológico Uacúsecha—discutiremos las características de la distribución espacial antes y después de la Conquista y sus implicaciones en la relación existente entre la sociedad, el paisaje y la cosmovisión de la población.

Among the numerous archaeological remains that recent LiDAR flights revealed in Guatemala and Mexico, agrarian features are the most abundant. Archaeologists today are compelled to revise their paradigms in terms of methodology and assessment of environmental appropriation for agriculture. The Malpaís de Zacapu in west Mexico is one example. Besides the discovery of a substantial Epiclassic occupation near the well-documented Postclassic urban centers of the area, LiDAR imagery brought to light a deeply modified agrarian landscape and thereby dramatically changed our understanding of human settlement in this lava flows complex.

Focusing on the northern part of the Malpaís, this study uses archaeogeographical and soil science methods to assess ancient farming systems and their evolution. We updated the archaeological and soil maps of the area, combining traditional field survey techniques and LiDAR-derived data interpretation. This allowed us to identify residential zones and a wide range of associated agrarian features adapted to the variety and agronomic challenges of volcanic soils. We further implemented a production-consumption model to reconstruct agricultural strategies from the Epiclassic to the Middle Postclassic period, from self-reliance to the necessity of supra-local agricultural inputs, possibly foreshadowing the Tarascan state tribute system.

According to Purepecha oral tradition, the ancestors of the Uacusecha dynasty that ruled Michoacan at the beginning of the sixteenth century began their epic in the Zacapu region. The importance of this region also lies in the research carried out since the early 1980s that led to the elaboration of a regional sequence outlining the trajectory of pre-Hispanic societies centuries before the emergence of the Tarascan state.

New research carried out on the area since 2009 has clarified this reference framework and opened new perspectives. The research focused on the Malpaís volcanic flows and its immediate surroundings. It addressed the transformations experienced by pre-Hispanic societies between a.d. 500 and a.d. 1580, and their interactions with the volcanic environment with unprecedented analytical detail. The joint contributions of remote sensing, archaeological fieldwork, dating, and geological study participate in renewing a diachronic approach of this unique landscape of northern Michoacan.

El período de aproximadamente tres siglos (600–900 d.C.), que corresponde al epiclásico, fue el escenario de una notable expansión de los asentamientos en la cuenca de Zacapu y sus alrededores. Si bien la zona parecía carecer de núcleos monumentales mayores equivalentes a los que se conocían en las regiones vecinas del Bajío o del sur de las tierras altas michoacanas, los trabajos recientes en la parte noroeste del Malpaís de Zacapu cambian esta concepción. Los datos proporcionados por medio del LiDAR y nuevos trabajos de campo revelaron complejos monumentales de dimensiones inéditas para la zona que estructuran una red de asentamientos menores distribuidos en un amplio territorio. Estos descubrimientos ofrecen nuevos datos sobre la arquitectura pública y doméstica de la época. La distribución de estos asentamientos y su relación con áreas dedicadas a la explotación de recursos agrícolas y mineros permiten vislumbrar un sistema más complejo e integrado, el cual pudo tener elementos comunes al de un altepetl. El objetivo de este artículo es presentar esta nueva información y reevaluar, a partir de ella, la organización territorial del período considerado.

En la cuenca lacustre de Zacapu a lo largo de su ocupación prehispánica (100 a.C. a 1450 d.C.), la dacita, una roca de origen volcánico, fue un recurso estratégico dentro de la economía regional, con el cual los antiguos habitantes de la zona elaboraron una serie de artefactos líticos ligados tanto a actividades de subsistencia y artesanales como rituales. Las investigaciones iniciadas en 2011 en dos minas-taller del yacimiento de dacita del Cerro Vicente expusieron una explotación extensa y organizada en torno a este recurso. En 2015, a partir de la cobertura LiDAR, se identificó un tercer complejo minero con evidencias de una explotación a cielo abierto y subterránea, esta vez en el yacimiento de Las Minas. Con el fin de comprender los mecanismos de explotación de la dacita, se ha llevado a cabo un análisis espacial de este sitio con distintas escalas de aproximación, para caracterizar las evidencias materiales vinculadas con la actividad extractiva. La combinación en nuestra investigación de la información que aporta el LiDAR y la proveniente de la prospección en el campo, nos ofrece un panorama completo del yacimiento, su organización espacial y funcional en un contexto más amplio como un paisaje prehispánico de extracción.

Recent years have seen the rapid expansion of airborne and spaceborne remote-sensing products adopted by archaeologists for interpreting ancient landscapes and managing heritage resources. A growing and increasingly specialized literature attests to the promise and availability of commercial and publicly funded satellite imagery, as well as UAV-mounted sensors across a range of resolutions and price points. In the South Caucasus (including the countries of Armenia, Azerbaijan, and Georgia), a growing commitment to landscape approaches in archaeology is stimulating the adoption of satellite remote sensing as an important new tool for identifying and managing archaeological resources while tracing the impact of historic land-use alterations in survey areas. Nevertheless, budgetary challenges and a lack of training opportunities among international partners and heritage organizations outside of the funding streams of large academic institutions can lead to widening technological gulfs in the discipline that reinforce colonial relationships. Building on recent technical articles covering specific imagery datasets, this article aims to address this by providing a general review of free or low-cost remotely sensed datasets available to archaeologists, with the aim of broadening awareness of these important tools and their vocabularies, and illustrating them with recent published examples from the South Caucasus.

The Michoacán-Guanajuato volcanic field (MGVF) hosts >1,400 monogenetic structures younger than 5 Ma. Here we focus on the Malpaís de Zacapu Late Holocene cluster located in the western part of the Zacapu lacustrine basin, situated in the heart of native Purepecha province. The Malpaís de Zacapu comprises four distinct eruptions: the Infiernillo lava flow emitted at ~1450 b.c.; Malpaís Las Víboras, a purely effusive eruption at ~1000 b.c.; the Capaxtiro compound lava flow at ~150 b.c.; and the most recent eruption, the Malpaís Prieto lava flow at ~a.d. 900. Although these lava flows are not inhabited today, they were densely populated in pre-Hispanic times (before a.d. 1521), especially during the Milpillas phase (a.d. 1200–1450). Volcanological studies (geochemical studies and detailed mapping using high-resolution DEM from LiDAR) allowed us to characterize these eruptions in terms of their magma source (rock chemical composition, mineral assemblage), age (radiocarbon and paleomagnetic dating), magnitude and dynamics (volume, morphology of the deposits), as well as lava flow emplacement duration. The findings allow us to infer the potential impact that these eruptions had on the pre-Hispanic settlement history of the area.

Within archaeology, the value of livestock is usually presented in terms of use values, the calories and products animals provide humans. Yet domestic animals are also sources of wealth that accrue symbolic and social values, tying livestock production to the reproduction of human social relations. Taking a Marxist perspective that recognizes dialectical relations between forms of value, we develop a model based on ethnographic examples in which the cycling between use value and social/symbolic values adhering to wealth in livestock are mobilized for the reproduction of ‘wealth in people’, or the accumulation of rights stemming from relationships between people. This model of cycling between forms of value can be applied to many ethnohistorical agropastoral political economies. We apply it to Pre-Pottery Neolithic B societies (c. 8500–7000 bc) in Jordan. During this time, the mode of production shifted from one grounded in the community to one centered on extended households. We suggest wealth in people was a key asset for LPPNB households and that wealth in livestock served as a major component of, and a particular ‘moment’ within, its reproduction. This might help explain the accelerated pace by which livestock production overtook hunting in the southern Levant in the eighth millennium bc.

Arguably the most enigmatic of the Maya calendar cycles, the 819-day count has challenged modern scholars for decades. Even today it is not completely explained and there are several areas for further research, including its relationship with the synodic periods of the planets visible to the naked eye. Earlier research has demonstrated a four-part, color-directional scheme for the 819-day count such that each of the calendar stations progress in increments of 819 days in cycles of 4 × 819 days. Although prior research has sought to show planetary connections for the 819-day count, its four-part, color-directional scheme is too short to fit well with the synodic periods of the visible planets. By increasing the calendar length to 20 periods of 819-days a pattern emerges in which the synodic periods of all the visible planets commensurate with station points in the larger 819-day calendar.

San forager populations in nineteenth-century southern Africa were forced to adapt to greatly destructive aspects of the colonial project. Forging new societies from heterogeneous sources, they engaged in prolonged armed insurgency, recording their exploits, presence and beliefs in the rock-art archive of the Maloti-Drakensberg. These images reference conflict and trauma, conventionally interpreted as visions of spiritual warfare. However, viewed through the lens of post-traumatic stress disorder (PTSD), deeper dimensions emerge. PTSD is the culturally subjective experience of generalizable neuropathologies which develop following a traumatic event. Diagnosable in diverse communities worldwide, it nonetheless requires insider idioms to understand its local expressions. We explore how PTSD manifested in this historic and cultural context; how its symptomatic social dysfunctions would have been understood in forager aetiology, and how its intrusive flashbacks would have intruded on altered-state experiences induced to heal the consequences of violence. We find that the artists were not passive victims of trauma, but rather used art symbolically to reconsolidate individual and collective understandings of traumatic events.

Theories derived from the ontological, posthumanist, or the new materialist turn have been increasingly employed in various fields within archaeology in the past decade. Recently, Roman archaeology also picked up on these theories: however, critical integration as well as more theoretical refinement is necessary to show the real potential of such theories. New materialism is not about writing a ‘history of objects’, but about a better ontological positioning of the non-human and human otherness. For Roman archaeology it can therefore be a powerful tool to broaden our perspectives on material culture and diverse social issues such as inequality, marginalized communities, slavery and coloniality. In this paper I will show how we can regard ontological fluidity in the Roman world through a new theoretical lens.

Direct accelerator mass spectrometry (AMS) dating is crucial for a correct integration of plant remains in the (pre)history of crops, particularly for those that do not belong to the Neolithic package and are known to arrive in Europe much later. This paper reviews one of the earliest records of rye from Romania. The grains were discovered in the tell settlement of Cunești, which belongs to the Gumelnița communities (ca. 4600–3900 BC). In 1954, due to Danube flooding, a large portion of the south part of the tell collapsed, and between the burnt dwelling visible in the resulting profile, a large number of sherds from three typical Gumelnița pots were identified. According to the excavation’s author, rye grains were found in association with those sherds, and it was assumed that a batch was stored in these Eneolithic vessels. Consequently, the rye was published as belonging to the Gumelnița period. Our reanalysis led to two radiocarbon (14C) dates, from two different laboratories, which indicate that the Cunești rye is not prehistoric but dates to the medieval period. To correct this error concerning this rye batch and the implications for European archaeology, we decided to republish these grains in an updated chronological framework. In addition, we performed stable isotope analyses on the charred grains, confirming they were cultivated on dry land, as well as a 3D morphometric investigation. Our research brings new and original data on rye cultures from the medieval period in southeastern Europe.

The presence of domestic animals is a key feature of the Neolithic. Their earliest presence in archaeological contexts across the European continent is often interpreted as reflecting farming practices. However, domestic animals often escape, survive, and become feral. Using the comparative example of colonial North America, this article's aim is to illustrate what happens when livestock are introduced to a new, continental temperate environment. Taking a dual historical and archaeological perspective, the author reiterates and elaborates on the suggestion that feral animals were almost certainly a feature of the European Neolithization process.
