Archaeological research on palaces and architectural spaces related to power factions allow a better understanding of the social dynamics of political economies. Several types of palaces appear in Mesoamerica according to distinct forms of sociopolitical organization. For Tlaxcallan, a Late Postclassic (A.D. 1250/1300–1519) geopolitical state-level polity with a highly collective government, the existence of palaces has been questioned. We reconsider the existence of palaces in Tlaxcallan through the contextual analysis of an architectural complex (CA-2) of Tepeticpac, one of the sectors of the conurbated area. We evaluate the functionality of CA-2 as a palace by examining the processes of occupation and abandonment of the building in relation to its architectural and stratigraphic sequence and the type of associated artifacts. The comparison between archaeological and historical data indicate that Tlaxcallans probably had palaces, but they were less ostentatious compared to others found in societies with more centralized governments.

This Special Section focuses on recent research centered on iron-ore mirrors in Mesoamerica and Central America. Iron-ore mirrors are rare and esoteric artifacts, mainly crafted by specialized centers in the Maya, central Mexico, and Zapotec areas from the Early Preclassic to the Postclassic. They were found in numerous archaeological sites and cultures, from the Gila River in the United States to the isthmus of Panama.

In this introduction, we present a temporal, geographical, and contextual framework for the actual knowledge on mirrors, in order to fully understand the complexity and importance of the research on these prestigious artifacts. Indeed, the mirrors combine spiritual and political power in a portable and material way, giving a great insight into Mesoamerican beliefs and leading to important information on the relation between rulers of different political centers from different cultural areas.

Finally, we present the articles of the Special Section and give an overview of their content and relevance to the topic.

This article revisits a long-neglected site in Northern Belize, the Classic Maya settlement of El Pozito, located in the Orange Walk District. Investigations led by Mary Neivens and Dennis Puleston explored the site between 1974 and 1976, documenting its architecture and recovering a substantial quantity of artifacts. Afterward, events conspired to bring these investigations to a close, leaving the site in a half-century scholarly limbo. The research here seeks to rectify this. Combining extant field notes with sporadic publications and recently conducted ceramic analysis, the authors reconstructed El Pozito's sequence of construction, occupation, and usage over 20 centuries. This new research revealed a settlement of surprising complexity, combining aspects of urban functionality amid a landscape of rural complexity. This article argues that the best way to understand such complexity is through the conceptual lens of a “town.” Neither a city nor a dispersed rural settlement, El Pozito functioned as a critical node that connected local, agrarian Maya with each other as well as the whole of the Classic Maya world. In this way, the research here seeks to rehabilitate this site, rescue it from its scholarly limbo, and restore its place in understanding the complex pre-Columbian landscapes of Northern Belize.

The Classic period lowland Maya used iron-ore mosaic mirrors and deposited mirrors in the burials of rulers and other people. Depictions of mirrors suggest that they were used for scrying, as were mirrors in Mesoamerica at the time of the Spanish arrival. Maya mirror users of this kind were conjurors, who used a variety of other divining and conjuring instruments and materials, including plates and shallow bowls. Three rulers at El Peru-Waka', now called Waka' by researchers at the site, an ancient city in northwestern Peten, Guatemala, were buried with mirrors and associated divining and conjuring materials. Following a brief introduction to the city and its temples, we describe the arrangement of mirrors and associated materials in three royal tombs. We suggest that the mirrors in these tombs were used in conjuring supernatural beings into existence, particularly Akan, a death god and wahy spirit who was a patron of the Waka' realm. We propose that the rulers and mirror conjurors of Waka' were oracles and that Waka' was known for prophecy. References to Sihyaj K'ahk' in text and iconography at Waka', and his association with oracular paraphernalia such as mirrors, lead us to propose a prophetic aspect of the visit of Sihyaj K'ahk' to the site eight days prior to his famous arrival at Tikal in a.d. 378. We suggest that the three rulers we discuss were mirror oracles sustained by the prestige of the prophecy of Sihyaj K'ahk'.

Slate disks have been reported from various excavations in the Maya Highlands. These artifacts have typically been described as supports or backings for iron-ore and pyrite mirrors. A number of these objects have been recovered in context at Kaminaljuyu, Guatemala. Whenever objects with reflective surfaces are identified in the field, they tend to be interpreted as mirrors, but they may have been worn as insignia on clothing. Recent finds at Kaminaljuyu, such as special deposits associated with Ballcourt B, suggest the use of reflective objects as part of the ballgame player's paraphernalia. The ballgame was an important ritual practice at Kaminaljuyu, as exemplified by the 13 ballcourts reported at the site. Archaeological evidence for this new interpretation will be presented, as well as a review of other examples excavated throughout the highlands, as part of an exploration of the exchange networks connected to regional trade in these exotic goods.

This article presents the results of a preliminary bioarchaeological study of 10 funerary urns containing human burned remains from the Los Tamarindos urn-field cemetery dated to the Postclassic period. I was able to determine the basic biological profile data. In addition, I determined the fragmentation rate as well as the thermal alternation of bones from funerary urns from Los Tamarindos, which allowed me to propose the first observations about the Pretarascan cremation burial practices in this region. The low weight of bones indicates that burials should be determined as partial burials; however, they contain fragments of bones from each anatomical region. The structure of the bones and the chromatic discoloration caused by the thermal alternation indicate that temperature during the cremation did not exceed 900°C, given that the cremains did not exhibit the recrystallization structure, which is interpreted as a characteristic feature of the high maximum temperature of a funerary pyre during the cremation.

Sea-level rise and settlement are investigated at Ta'ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves tolerate salt water, but under conditions of sea-level rise, the plants grow vertically to keep their leaves above water. Sediment, leaves, and detritus trapped in the prop roots form mangrove peat, which serves as a proxy for sea-level rise. AMS dating of fine red mangrove roots determined that the local sea levels rose at Ta'ab Nuk Na throughout the Late Classic period and continued into the Postclassic period. Radiocarbon dates obtained from the wood-post samples yielded Late Classic–period dates. Comparing the radiocarbon dates from the wooden posts and the sediment core samples determined that the site was abandoned before the rising seas flooded the area. Evidently, sea-level rise did not play a role in site abandonment.

Nearly 60 complete or fragmentary slate backings from iron-ore mirrors have been found in pre-Columbian funerary contexts in northern Costa Rica, including a couple that bear Maya hieroglyphic inscriptions. With the exception of a single example dating between a.d. 800 and 1550, these slate objects typically occur in contexts dating from 300 b.c. to a.d. 500–600. Recent geochemical analyses indicate foreign production of these artifacts, likely in the Maya area, where slate-backed iron-ore mirrors were related to power, shamanism, and divination, and were manufactured by highly specialized artisans working under the patronage of members of the elite, particularly in the Classic period. In this article we address the question of when, how, and why mirrors from Mesoamerica made their way to Costa Rica and, ultimately, into the funerary contexts from which they have been recovered. To that end, we analyze the regions, contexts, style, and chronology of these Costa Rican examples and compare them with contemporary styles and contexts in the Maya area, including a reinterpretation of one mirror-back presenting hieroglyphic inscriptions. Finally, we explore potential distribution routes and the potential mechanisms of exchange that existed between these distant, yet somehow related areas.

In this study, I use the type-variety-mode analysis to define the diagnostic ceramic material for the Ik'hubil Ceramic Complex dating to the Terminal Classic (ca. a.d. 780–930/1000). The percentages of shared ceramic content indicate that multiple sites in the mid-to-lower Sibun Valley are members of an Ik'hubil Ceramic Sphere. My preliminary analyses of sites in the lower Belize River valley suggest that the Ik'hubil Sphere may extend across a broader area of north-central Belize during the Terminal Classic, discrete from the Spanish Lookout Sphere in the upper Belize Valley. Northern Yucatec traits are identified in ceramics and architecture in the eastern Sibun and Belize Valleys, along with marked changes in foodways. The presence of trading diasporas and more intimate social relationships, such as intermarriage, may explain this mix of local and hybrid forms of material culture introduced by the ninth century in this part of the eastern Maya Lowlands.

El sitio de Tak'alik Ab'aj se encuentra en la bocacosta suroccidental de Guatemala. Durante las excavaciones del Entierro 1 de la Estructura 7A, fechado para finales del preclásico tardío (150 d.C.), se recuperó un rico ajuar funerario compuesto por decenas de piezas de jadeitita, hematita, pirita y cuatro mosaicos “reflectores” de este mismo material. Cada uno fue labrado con la misma tecnología de manufactura y soporte “flexible” de fragmentos de cerámica (ensamblados con resina) por primera vez documentado, y diseño propio para la función y significado que desempeñara. Dos de ellos fueron integrados en la pechera y faldellín del traje ceremonial; los otros dos como parte del ajuar adicional de un posible portaestandarte.

En este trabajo se incluye el estudio traceológico-tecnológico de las teselas de estos mosaicos del Entierro 1 a través de la caracterización de sus huellas de manufactura con arqueología experimental y microscopías óptica y electrónica de barrido. De esta manera se detectó una elaboración muy estandarizada en la que se aprovecharon instrumentos hechos con rocas volcánicas locales, como la dacita, cuyo sello tecnológico no ha sido reportado hasta el momento en otra colección lapidaria maya.

Different types of iron ore and pyrite were used to craft a wide variety of reflective artifacts in pre-Columbian Mesoamerica, including “mirrors,” pectorals, necklaces, and dental inlays, among others. In the Maya region, most of these have only been visually assessed, without using analytical techniques. Consequently, our understanding of the diversity of raw materials used in artifact production has been limited. This article presents preliminary results from a pilot study aiming to identify the raw materials used in the manufacture of different reflective objects from a small sample of finds from the sites of La Corona and Cancuen, located in Guatemala, through the use of scanning electron microscopy with EDS detectors (SEM-EDS), energy-dispersive X-ray fluorescence (EDXRF), X-ray diffraction (XRD), and Raman spectroscopy. Although further analyses are needed to confirm the representativeness of the sample, these results indicate the use of hematite and goethite (iron oxides), but not pyrite (iron sulfide). This study also shows how improved knowledge of raw material use can elicit previously unknown patterns of distribution and exchange, and highlight patterns of inter- and intrasite variability in the production, use, and exchange of reflective objects over time in the Maya region throughout the Classic period.

This article presents and analyzes a newly discovered petroglyph from Tetzcotzinco (mun. Texcoco, Mexico) in the form of arranged pecked dots. Based on what is known about Mesoamerican divinatory systems, calendars, and the perception of space, the interpretation takes into account both the encoded numerical values and the layout of the dots. The main argument is that this and similar representations’ function was not limited to simple counting of days or serving as a kind of astronomical marker, in which the arms of the cross indicated, for example, equinoxes, which is by far their most common interpretation in academic literature. Instead, it represented calendrical cycles through the numbers, as suggested by some scholars. Based on this hypothesis, the article explores the possible connection between numbers registered in Tetzcotzinco's “pecked cross” and specific diagrams from indigenous divinatory books. Therefore, the plausible interpretation of the symbolism of this petroglyph is that it either expressed a series of meanings related to the agrarian period(s) and rain god(s) or less-known Mesoamerican calendrical cycles, such as half trecenas or seven- and nine-day periods.

Drawing upon iconological theory, this article argues that mirrors and blood were regarded as a conceptually linked pair within the imperial ideology of Teotihuacan, Mexico from the second century onward. The relationship between blood and mirrors is shown to have codified with the construction of the Pyramid of the Feathered Serpent, Teotihuacan's third largest edifice. This monument's facade was adorned with hundreds of monumental sculptures of oracular mirrors, some number of which incorporated actual mirrors formed of obsidian. I demonstrate that the Teotihuacan mirror sign took obsidian, a form of black volcanic glass that was intensively worked in the city, as a key referent. This monument was also the site of a historically large human sacrifice of more than 200 individuals, an event argued here to have involved bloodletting with obsidian knives and blades. I note that Teotihuacan interest in the mirror icon increased in concert with the city's residents’ application of the reflective material of obsidian to warring and other blood-spilling behaviors. The mirror icon evoked both obsidian as a radiant material, as well as obsidian's potential for application to forceful martial actions. The article concludes that this icon in part signified imperial force, which was made real through the weaponization of the smoking glass.

Although iron-ore mirrors are commonly found in the Maya area, very few workshops are known to date. Cancuen, Guatemala, is one of the few sites to show evidence of iron-ore production during the Late Classic (a.d. 600–800). This article reviews all the available data on this material in Cancuen in light of the recent excavations, and, by combining spatial and technological analysis, proposes to shed new light on the spatial organization of this production. By comparing the composition and the social context of production in Cancuen with that of Aguateca (Inomata and Eberl 2014), we suggest that there was a division of tasks between sites in which Cancuen's artisans were involved in the first stage of the production of luxury goods, whereas other stages, such as the arrangement of the tesserae on the supports and their repolishing, were more socially invested and made by elite artists at the recipient sites.

Sounds produced by humans and their environment are perceived and codified based on people's experiences as members of social groups, resulting in some sounds being used as means of communication. In this article, we present an archaeoacoustic study of diverse types of instruments excavated or collected from Comalcalco and Jonuta, two important pre-Hispanic Maya sites located in the modern state of Tabasco (Mexico). We propose a methodology to analyze organological and acoustic characteristics for each type of instrument, considering their relevant archaeological information, so as to provide some interpretations of how sounds could have been materialized, shared, and used in specific moments of Maya ritual and daily life.

Desde la antigüedad, los artefactos de pizarra fueron utilizados por sociedades asentadas en diversos puntos del continente americano; su uso abarcó diferentes temporalidades y múltiples formas.

En el caso particular de Teotihuacán, ubicado en el centro de México, los artefactos en cuestión se reportan dentro y fuera de esta ciudad, depositados como ofrenda y asociados directamente al fuego, al agua y al inframundo. Aunque la pizarra fue una materia prima con una presencia constante en Teotihuacán, sólo se reconoce cuando aparece asociada a los espejos, cuando presenta diseños iconográficos, o con evidencia de decoración. Al respecto, en este texto señalamos la importancia de la pizarra en Teotihuacán, su cronología y contexto. De acuerdo con los resultados de los análisis tipológicos, geológicos y de caracterización, proponemos el aprovechamiento de diversas materias primas dentro de un mismo yacimiento, así como la identificación de las áreas de extracción de la pizarra utilizada por los teotihuacanos a través del tiempo.

Estos datos nos permiten inferir las funciones rituales, simbólicas y jerárquicas de esta materia prima dentro de la metrópoli teotihuacana.

Smith and Kidder (1951:44) were among the first to highlight pyrite pre-Hispanic mirrors as “marvels of painstaking craftsmanship.” These mirrors present reflective surfaces consisting of 20–50 pyrite tesserae with beveled edges, perfectly cut, and average 2 mm in thickness. The first known examples of mirrors in Mesoamerica were the “Olmec” type—a concave mirror created from a single hematite piece developed during the Middle Preclassic period. Later, in the Classic period, pyrite mosaic mirrors replaced them. Unfortunately, we do not understand the changes from one type to the other. In this work, we present two pyrite mirrors found at the site of Chiapa de Corzo, Chiapas, Mexico, dating around 700–500 b.c., as possible forerunners of Classic pyrite mirrors. Also, we present traceological analysis of their manufacturing process using experimental archaeology and scanning electron microscopy. Based on these examinations, we identify likely materials and techniques employed in crafting them. We posit that production of these mirrors could have been the result of the development of specialized artisans at distinct workshops, increasing the complexity and labor investment in the lapidary objects as prestige goods.

We describe an analysis of the flaked stone tools recovered from households in the Postclassic central Mexican city of Calixtlahuaca (a.d. 1130–1530). Most artifacts are obsidian and represent the blade-core technology, but biface and bipolar artifacts are also represented. Even though household residents were involved in limited biface and bipolar reduction, it appears that the city did not have any resident blade producers. This finding is at odds with the views of many archaeologists, who tend to associate craft production with the emergence of complex Mesoamerican urban centers. We examine the technologies from temporally distinct Calixtlahuacan household assemblages. We discuss why the quantity and quality artifacts associated with blade production are not consistent with resident blade making in the city. Finally, we examine four models for blade provisioning: (1) whole-blade trade, (2) processed-blade trade, (3) long-distance itinerant craftsmen, and (4) local, hinterland-based craftsmen. Evaluating how the Calixtlahuacans got their flaked stone tools has important implications for the comparative understanding of the organization and scale of economic provisioning systems in Postclassic central Mexico. This analysis supports new inferences about the nature of commercial networks that supplied the Toluca Valley prior to the arrival of the Spanish in the sixteenth century.

This article utilizes the Maya Hieroglyphic Database (Looper and Macri 1991–2022) to study the spellings of three glyphic values based on T713 (Thompson 1962), namely, the logogram K′AB′ ‘hand, arm’ (n = 88), the logogram K′AL ‘to close, wrap, adorn’ (n = 484), and the syllabogram mi (n = 68), cataloged as MZ1, MR1, and MR2, respectively, by Looper et al. (2022). The main goal is to study the functions of certain graphemes typically placed atop T713 (T713's “holding site”) when it has the value K′AL, and to determine to what extent such signs can be described as lexical determinatives. The article concludes that MZ1 K′AB′ constitutes the unmarked value of T713, while MZ1 K′AL requires contextual or graphemic disambiguation, the latter facilitated by means of phonetic complements (e.g., k′a or la) or lexical determinatives (e.g., T617/1M3). Syntagmatic contextual associations resulting from frequent proximity to other signs was a common factor in the establishment of certain signs as lexical determinatives. The question of MR2 mi, which can be analyzed as either a digraph or a case of a “phonetic determinative” (distinct from “phonetic complement”) in the holding site of T713, is left open to future research.

The Kaan (“Snake”) kings, a powerful political entity in the Classic Maya Lowlands, were housed in the Early Classic period at Dzibanche, and they moved their capital to Calakmul by the year a.d. 642 (Helmke and Awe 2016; Martin 2020:138–139). Their network of alliance and intermarriage radiated southward, and Waka's early eighth-century queen, Lady K'abel, was from the Kaan bloodline and married in to the Wak lineage, exemplifying the close connection between the two political entities. The discovery of Stela 44 in tunneling efforts in M13-1, the city's important ritual center, allows us to trace political ties between the Kaan and Wak kings to significantly earlier than previously known, which seem to begin around the mid-sixth century. This monument provides insight into three converging lines of evidence supporting the profound alliance these elites had built: first, the accession of a Wak king, Wa'oom Uch'ab Ahk, under the supervision of the Kaan king K'ahk’ Ti’ Ch'ich’; second, the father of the new king, Chak Tok Ich'aak, seems to be connected to La Corona, another early Kaan ally; and third, the mother of Wa'oom Uch'ab Ahk, Ix Ikoom, is also connected to La Corona and the broader Kaan hegemony through her title ix sak wahyis.
