Tras revisar los datos arqueotanatológicos registrados desde el siglo diecinueve y realizar el análisis bioantropológico de todos los componentes esqueléticos humanos correspondientes, exponemos por primera vez un análisis integral del patrón mortuorio de Palenque-Lakamha’, cuya monumentalización data del Clásico Maya. Describimos la amplia distribución de sepulturas en los diferentes sectores del asentamiento, el elevado número de edificios dedicados a las prácticas funerarias, la preferencia por el uso de cistas, la frecuente colocación de más de un individuo en el mismo espacio sepulcral y la estandarización de la posición extendida en decúbito dorsal, con orientación al norte.

Un aspecto sobresaliente es el reingreso a los sepulcros, particularmente en entierros colectivos, depositados en contenedores de piedra, que presentan remoción, desplazamiento o ingreso de muertos y/o artefactos. Además de la identificación de esta secuencia funeraria que explica la desviación del patrón mortuorio, se propone una interpretación basada en datos etnográficos para entender la interacción entre vivos y muertos.

La distribución de los sepulcros, la prominencia de la actividad post-inhumación y los datos iconográficos y epigráficos sugieren que Palenque-Lakamha’ pudo haber sido un lugar vinculado al pasaje liminal hacia el inframundo, donde la frecuente interacción con los muertos y el importante número de mausoleos permitía entablar diálogos con el sagrado y, por ende, renovar los ciclos cósmicos.

The central Maya lowlands (CML) display an uncommon demographic history—the absence of a millennial population rebound from its former occupational peak, about 800 CE. Here we postulate why the loss of a well-populated CML during the Late Classic-Terminal Classic periods failed to regain substantial occupation during the subsequent 700-800 years before the Spanish conquest of the Maya realm. Updating the narrative of stressful human-environmental conditions, shifts in trade routes, and long-term paucity of occupation in the CML, we examine push-pull factors that affected Postclassic Maya population geography. These factors include population pressures, environmental hazards, resource conditions, and livelihood standards that existed in the Postclassic Period between northern and coastal lowlands and the CML. The advantages that the CML maintained before Postclassic times, foremost regaining superior environmental conditions for agriculture, were insufficient pull factors given the low levels of push factors in the northern and coastal lowlands. We draw attention to the under-treated problem—the failure of a population rebound in the CML—and encourage improvements in systematic data and analytics to address it, including consideration of non-material, socio-cultural factors.

This article examines the measurement systems used in the built environment of Xochicalco, a significant Epiclassic archaeological site located in Central Mexico. Through careful analysis of the dimensions of the various structures, we identified two primary measurement units: U7 (1.47 m) and U8 (1.68 m). These units exhibit similarities to the Mayan zapal and Nahua maitl, which have been previously documented across diverse temporal contexts and other regions within Mesoamerica. The investigation revealed patterns in the application of these units related to orientation, functionality, and construction methods, indicating meticulous planning and potential symbolic importance. The frequent use of measurements that are multiples of three, four, nine, and twelve times the base units suggests the utilization of standardized measuring instruments. This study enhances our understanding of Mesoamerican measurement practices, particularly at Xochicalco, and provides insights into cultural interactions and construction traditions during the Epiclassic period.

Maya Blue is a unique hybrid pigment created by combining organic indigo with the inorganic clay mineral palygorskite. First used for architectonic decoration in the Terminal Preclassic, it became widespread in the Late Classic on figurines, murals, and elite ceramics. Unlike indigo, it is notable for its durability and resistance to degradation by acids, alkalines, organic solvents and fading. The authors analyzed 17 samples of Maya Blue on pottery from the Late-Terminal Classic periods, a.d. 680–860, from Buenavista del Cayo, Belize. Using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), it was determined that the palygorskite in these samples likely came from Sacalum, Yucatan, some 375 km away. The authors suggest several routes by which palygorskite might have been transported from Yucatán to Buenavista. The pigment or knowledge of how to produce it likely was conveyed through high-status exchanges rather than commercial trade. Maya Blue held significant cultural and religious importance. It symbolized water and rain and was associated with the god Chaahk. Maya Blue appeared initially at Buenavista on architecture and rare imported ceramics but its use gradually increased on locally produced Belize Valley wares. Use at Buenavista peaked in the early 9th century before disappearing around a.d. 860. The study demonstrates the potential of trace element analysis in identifying long-distance social interactions in ancient Mesoamerica.

Greenstone is commonly used to produce culturally significant items across Mesoamerica, including axes, earspools, figurines, and beads. This research characterizes the mineralogy of greenstone materials recovered from sites in the Jovel Valley, Chiapas, Mexico, to document the range of green minerals utilized by the inhabitants. Our analysis of the objects suggests that the Late Classic and Early Postclassic Maya of the Jovel Valley had access to a variety of greenstone minerals, including serpentinites, green micas, grossular, and jadeite. X-ray diffraction and X-ray fluorescence spectrometry characterization of reference materials suggests procurement of greenstone resources from the well-documented sources of the Motagua–Polochic Fault Zone, and also potentially from sources in the Chalchihuitán–Chenalhó area of Chiapas, Mexico. The Jovel Valley had access to materials over long distances through historically documented trade routes that allowed the movement of greenstone materials west from the Motagua River Valley into highland Chiapas or south from the Chalchihuitán–Chenalhó area.

We present a synthesis of treatment of the dead from before 700 b.c. to the fifteenth century a.d. in the lower Ulúa River Valley of northern Honduras. Building on evidence of burial alignments to a prominent mountain first identified for the Classic period, we argue that mortuary rituals served to integrate politically independent communities within a shared cosmological landscape. We identify alignment of burials toward the same mountain beginning in the Middle Formative period. At this time, a cycle of mortuary treatment resulted in bodies of some of the dead being commingled in shared secondary burial sites in caves, significant locations in the cosmological landscape. During the Classic period, secondary mortuary treatment continued, now performed within settlements again united by orientation to a shared cosmological landscape. The addition of solar alignments may be evidence of adoption by some families of Lowland Maya cosmological beliefs. This impression is solidified in Postclassic burial practices that align closely with those of specific Lowland Maya societies. We argue that the afterlife cycles through which the living interacted with the dead, in a tension between individualization and communal belonging, included strategies through which social relations, community histories, and ties among communities were created.

In 2017, the authors supervised the recovery of a pre-Hispanic stone sculpture near the community of La Victoria, in the Sierra de los Tuxtlas, southern Veracruz, Mexico. The fortuitous discovery of this monument afforded a rare research opportunity to conduct a controlled, systematic archaeological investigation of a known, but poorly documented, Early Classic–period (a.d. 300–450) sculptural tradition. Moreover, this archaeological salvage project facilitated a crucial dialogue with local stakeholders regarding the recovery and final disposition of the monument. This collaborative effort enabled researchers to wed governmental oversight and academic interests with the concerns of local stakeholders, thereby furthering the investigation, conservation, and public appreciation of Classic-period archaeology along Mexico's southern Gulf Lowlands.

In the present discussion, I will focus on the creation of baby warriors in Mesoamerica in a twofold manner: as human beings and as blade stones. The emphasis will be on central Mexico, complemented with essential data from other parts of Postclassic Mesoamerica. By juxtaposing information from historical sources in a novel way, this investigation seeks to offer new insights that should reinforce the idea that warriors captured on the battlefield were considered to be children. Although this idea has been suggested before, this article aims to contribute new historical evidence that not only confirms this notion but also widens our understanding of the creation of nonbiological offspring. Making kin out of Others aims to satisfy a cosmological need to incorporate vital energy and elements for individual and collective personhood from outside of the community. The second idea of this investigation focuses on a related productive variant of this gestational dynamic, suggesting that by stone flaking and chipping, children (of stone) were fabricated. Some of them were indeed “child blade stones” who personified warriors and fed themselves with sacrificial victims, securing sustenance for the hungry gods. I argue that the birth of these warriors should be integrated into a major mythological theme—namely, the Child Hero and the Old Adoptive Mother.
