CORRELATION BETWEEN SPECTRAL, SEM/EDX AND ELECTROCHEMICAL PROPERTIES OF MAYA BLUE: A CHEMOMETRIC STUDY*

2009

Visible spectra, composition from SEM/EDX and solid-state electrochemical data are correlated for a set of 12 Maya Blue samples from different archaeological sites of Campeche and Yucatan (Mexico). In addition to indigo and dehydroindigo, indirubin and other possibly indigo-type compounds can be detected in Maya Blue samples. Application of hierarchical cluster analysis techniques allows similarity relationships to be established between samples from different sites, confirming prior results which suggest that the preparation of Maya Blue pigment evolved with time during the Maya culture following a ramified scheme.

Tiempos de crisis y cambios socioculturales en Chupicuaro al final del Preclásico: evidencias paleoambientales e indicadores arqueológicos en el vall…

2012

International audience; "Los trabajos realizados en el valle de Acámbaro evidenciaron para finales del Preclásico (hacia 100 a.C.), una serie de cambios que denota un tiempo de crisis y de transición. El estudio revela una reducción drástica del número de sitios del Preclásico Terminal (fase Mixtlán: 1-250 d.C.), así como una nueva configuración espacial. Las excavaciones avalan las observaciones de superficie y comprueban que, a partir de 100 a.C., los asentamientos sufren una desocupación: en dos sitios excavados observamos estratos de abandono y luego de reocupación, y en los demás constatamos un abandono definitivo. Esta evolución parece coincidir con una baja demográfica. Los acontecim…

Alcance y límites del uso antropológico de algunos conceptos de la filosofía de Wittgenstein. Plantas sagradas, magia y el culto de San Simon en Guat…

2021

Ante todo, mi objetivo era aclarar los aspectos múltiples y superpuestos del lenguaje religioso, y el debate que se ha desarrollado primero entre Wittgens-tein y Frazer, y luego con otros autores posteriores. En segundo lugar, quería para mostrar cómo los conceptos wittgensteinianos sobre el lenguaje religioso pueden encontrar una aplicación en el campo antropológico - con la idea de verificar la fiabilidad de las herramientas metodológicas e intelectuales suge-ridas por el filósofo vienés en el análisis de rituales mágico-religiosos - he aplicado sus ideas a tres estudios de caso en el campo de la antropología social en el ámbito mesoamericano: el culto a San Simon de Guatemala, los ritual…

Multianalytical characterization of pigments from funerary artefacts belongs to the Chupicuaro Culture (Western Mexico): Oldest Maya blue and cinnaba…

2019

Abstract The colours used in Pre-Hispanic Mesoamerica to decorate walls, codices or artefacts have been the subject of numerous studies, with particular attention to Maya blue, red and white pigments. However, most of these studies have been focused on emblematic cultures of the Classic period (ca. 300–1000 CE), such as Teotihuacan and Maya cultures. This work proposes a new chronology of the preparation and use of these pigments, particularly Maya blue, by analysing samples of the Pre-Classic period (ca. 1800 BCE–300 CE). The samples belong to ceremonial artefacts decorated with blue, red and white pigments, in a funerary context from the Chupicuaro culture, which was developed between 600…

Characterization of prehispanic cosmetics found in a burial of the ancient city of Teotihuacan (Mexico)

2012

The present paper reports the chemical data obtained on samples of pigmenting materials contained in 31 miniature vessels found in a burial found in Teopancazco, a multiethnic neighborhood center located in the southeastern sector of the archaeological site of Teotihuacan (Central Mexico) and the analytical protocol established for the complete characterization of these archaeological materials. For this purpose a multi-technique approach based on the combination of several non destructive and micro-destructive instrumental techniques, namely, light microscopy (LM), scanning electron microscopy-X-ray micro-analysis (SEMe EDX), transmission electron microscopy (TEM), voltammetry of micropart…

An anthracological approach to understanding Late Classic period cultural collapse in Mesoamerica’s northwestern frontier

2012

International audience; For over 50 years, researchers have suggested that increased regional rainfall over the highland deserts of Mesoamerica's northwestern frontier zone during the Classic period (AD 200-900) allowed for the colonization of the zone by farming groups who originated from Central and/or West Mexico. A severe and prolonged drought is hypothesized to have later provoked the abandonment of the region by these sedentary populations by AD 900. However, very little research has been carried out in the zone to detect evidence of this proposed climate change. I present results from the first systematic study of wood charcoal from the northwestern frontier, comparing the data from …
