Understanding the Quadruple Flutes of Teotihuacan, Mexico

This paper presents the results of a study on the quadruple flutes (multiple pipes) from the UNESCO World Heritage Centre of Teotihuacan, Mexico, based on a thorough examination of the fragmented, restored and partly reconstructed archaeological finds and the manufacture and subsequent test of a series of playable reproductions with a refined reconstructive design. For the latter, organological features, such as the diameter, number and position of the fingerholes/tone holes and the length of the individual pipes of the restored finds are challenged and a new design is proposed that might be closer to the original construction of the Teotihuacan instruments. The study reveals a better understanding of the particular construction, acoustics and musical possibilities of the Teotihuacan quadruple flutes.

Sonic Artefacts of Teotihuacan, Mexico (Horns, Trumpets and Pipes)

This paper presents the acoustic study of a sample of sonic artefacts, in particular a selection of wind instruments (horns, trumpets and pipes), from the UNESCO World Heritage Centre of Teotihuacan, Mexico, based on a thorough examination of the accessible and playable archaeological finds and the construction and subsequent test of a series of experimental models. Combined with the archaeological and iconographical information, the study helps to deduce information with regard to the urban settings in which these instruments might have been used. It also reveals some basic acoustic components of the music once performed in Teotihuacan.

Numerales y cómputo del tiempo en la iconografía de Teotihuacan, México

Este trabajo identifica íconos de numerales asociados a dos tipos de cómputo del tiempo plasmados en el arte de Teotihuacan durante el periodo Clásico (150-650 dC). Primero, se analiza la pintura mural del altar de Atetelco, distinguiendo seis íconos de números y un símbolo matemático empleados para computar cuentas de 104 años trópicos, y 72 y 7.300 ciclos sinódicos de Venus. Un segundo análisis muestra que ambas cuentas fueron usadas en obras de estilo teotihuacano mediante una iconografía distinta al sistema numérico de puntos y barras. Las fechas teotihuacanas pueden ser correlacionadas con los registros de la cuenta larga del área Maya, lo que nos permite datar los monumentos y artefactos arqueológicos mediante la iconografía. La evidencia muestra que los teotihuacanos midieron el tiempo a largo plazo plasmando las cuentas en complejas obras como parte de la institucionalización del registro del tiempo.

Nuevas estrategias turísticas en Teotihuacán, México tras la pandemia Covid-19

El turismo cultural en el valle de Teotihuacán, México, tiene la oportunidad de diversificarse y ofrecer nuevas estrategias tras la pandemia del Covid-19, mediante el aprovechamiento de los recursos históricos y tradicionales con que cuenta, para reducir la excesiva carga turística en la zona de monumentos prehispánicos. En este trabajo presentaremos opciones para establecer nuevos circuitos de visita, basados en el patrimonio inmaterial de la región, como la base de nuevos productos turísticos sostenibles, con medidas de bioseguridad que garanticen al visitante una estancia saludable e informada. El estudio está enfocado a buscar alternativas para mantener el flujo de visitantes al valle, pero distribuidos en una serie de atractivos que dinamicen de manera directa sectores sociales como el artesanal y el gastronómico, potencializando la categoría de Pueblo Mágico que comparten las cabeceras municipales de Teotihuacán y San Martín de las Pirámides.

A HIGH-RESOLUTION CHRONOLOGY FOR THE PALATIAL COMPLEX OF XALLA IN TEOTIHUACAN, MEXICO, COMBINING RADIOCARBON AGES AND ARCHAEOMAGNETIC DATES IN A BAYESIAN MODEL

ABSTRACT Teotihuacan is one of the most studied archaeological sites in Mesoamerica because of its exceptional size and urban planning; however, its last years of occupation and abandonment are still under debate. We report a high-resolution chronology for the Xalla complex integrating archaeomagnetic dates, radiocarbon (14C) ages, and detailed archaeological information about sample type and context in a Bayesian model. The model includes 42 14C ages and 7 archaeomagnetic dates grouped in 6 phases, including samples from collapsed roofs with 14C ages earlier than expected, suggesting a problem of inbuilt age. The archaeomagnetic dates on lime plasters were classified in unburned samples, related to the time of construction, and burned samples, related to the Big Fire associated to the abandonment of Teotihuacan. The modeled 14C ages resulted in shorter intervals, with the possibility of differentiating the construction phases, confirming that big beams had inbuilt age. Further, combining the two dating methods and classifying lime plaster samples in burned and unburned, it was possible to date different events within the same archaeological context. It is concluded that by combining these two dating methods and understanding the moment that each sample is dating, it is possible to obtain solid and precise chronologies.

THE TEMPLE OF QUETZALCOATL, TEOTIHUACAN: NEW DATA ON THE ORIGINS OF THE SACRIFICIAL VICTIMS

Continuing isotopic investigation of the sacrificial burials and trophies beneath the Feathered Serpent Pyramid (Temple of Quetzalcoatl) in ancient Teotihuacan, Mexico, has produced new results. Isotopic proveniencing using bioapatite strontium and structural carbonate oxygen isotopes in tooth enamel was applied to 39 samples, 24 from the sacrificial victims and 15 from the trophy jaws. Both the strontium and oxygen isotope ratios suggest that most or all of the sacrificial victims came from the central highlands of Mexico, which includes the area of Teotihuacan. In this sense, we find somewhat less multiethnicity represented among the military at Teotihuacan than previously thought. Analysis of carbon isotope ratios in enamel structural carbonate indicated a childhood diet dominated by maize, relatively homogeneous among the victims at the pyramid, and typical for much of pre-Hispanic Mesoamerica.
