It is estimated that this large format manuscript has 800 pages and 300 colorful plates describing key historical passages and geographic descriptions of the key towns and villages of Mexico after the Conquest and during the first century of Spanish domination. Nevertheless, many scholars have expressed skepticism as to the authenticity of this mesmerizing mammoth-sized document. A recent controversy in Mexico has again raised this issue, as a Spanish gallery purchased one of these Cardona fragments and has recently sold it for US $200,000. Upon the request of the Biblioteca Nacional de Antropología e Historia, INAH, I inspected and analyzed the materiality of one of the purported fragments of the Codex Cardona in Mexico with portable spectrometry. I present in this poster the results of these scientific analyses and a tale of caution about one of the most elaborate forgery schemes known for Mexican manuscripts.

The Smoking Mirror, 2020

During 2017, several research teams analyzed the codex using both non-invasive and invasive methods to produce the largest scientific corpus of data ever created for any Mesoamerican codex to date. Here, I present the results of the tests undertaken by the Colors of History Project and Laboratory of the University of Colorado-Boulder. The presence of the pigment Maya Blue was confirmed; in addition, no modern inks or materials were found, and three more AMS C 14 dates placed the manufacture of the document in the Early Postclassic period. All of the material evidence rejects the idea that this document was a fabrication of the 20 th century; instead, the various studies support the authenticity of the Códice Maya de Mexico and place it as the oldest surviving book manufactured in the Americas.

Economic Anthropology, 2022

We argue that the root cause behind Indigenous depopulation in North America was not the lack of immunological defenses against novel pathogens introduced to the New World from the Old World, a hypothesis known as "Virgin Soil." Certainly many Indigenous people died of disease, but so did many Euro-American colonizers. The populations of colonizers rebounded, as most populations do, but Indigenous populations could not recover because of colonizer violence and the persistent marginalization perpetrated against them. We show that European settlers promoted and practiced an ideology of domination based on an exaggerated perception of risk against Indigenous communities. On the basis of colonial prejudices, they created a distorted perception of Native Americans that depicted them as dangerous savages, un-Christian, and untrustworthy. Native Americans were seen as capable of damaging the life and property of the colonists and as incapable of being assimilated by them. Colonists assessed the Indigenous groups as an unacceptable and intolerable risk that had to be eliminated, irrespective of the financial cost of waging war on them. This ideology of risk has continued to impact the lives and well-being of Indigenous people for more than five hundred years as demonstrated by the elevated deaths from COVID-19 for Native Americans and other persons of color. Structural inequalities derived from the ideology of risk are behind the deaths of Indigenous people even today. Risk can be approached as the probability of occurrence of a hazardous event and its consequences (risk = probability of loss/gain * danger * exposure * vulnerability). Specialists in the social sciences know that risk involves a balance between profit and loss, and there is risk associated with every aspect of life (Douglas 1985; Douglas and Wildavsky 1982). Indeed, risk-aversion behaviors may bring high opportunity costs, such as the loss of income to individuals or groups, and may be irrational from the point of view of classical economic theory (Blaikie et al. 1994). High risk, high returns is at the core of modern financial and insurance markets, on which the modern economy relies. Nevertheless, the public approaches risk based on the negative consequences and threats to human life, on bodily injury, or on loss of welfare due to external dangers outside their control. Risk assessment by most laypeople tends to be based on perception, and it is easily manipulated by propagation of irrational fear. We

ARCHAEOLOGICAL PERSPECTIVES ON THE STUDY OF OUTBREAKS DURING THE COVID-19 PANDEMIC COEVOLUTION, EMERGENCE, AND RESURGENCE OF PATHOGENS THROUGH HISTORY, 2021

Past epidemics have impacted large sectors of the population in affected regions, disrupted economic activities, and increased
social unrest. A pandemic like COVID-19 demands that we assess our weaknesses and strengths as a global society, or as societies across the world. The present pandemic encourages us to pause and to remember that, despite dwelling in artificial environments provided by powerful social and technological systems, we are still subject to ecological checks. It is precisely during moments of crisis when we can better observe structural
inequalities within our home communities and our global community more broadly. These are the right moments for taking political action to attack the root causes that produce and maintain vulnerabilities and inequalities.

No se encuentran elementos que apoyen que este documento sea una falsificación o haya sido alterado para hacer pasar materiales modernos como antiguos.

Se resalta que la mayoría de los académicos que han escrito acerca de este códice no lo han observado directamente y fundan sus argumentos con base en un número reducido de tomas fotográficas del documento. Esto ocasiona que se repitan juicios incorrectos acerca de la materialidad del códice. Hasta el momento ningún estudio previo había publicado imágenes de las microestructuras del códice con las magnificaciones adecuadas, por lo que esta investigación incluyó una toma completa del documento en fotomacrografía.

Se ubica este códice firmemente en el Posclásico temprano, con una alta densidad de probabilidad entre los años 1021 y 1154 d.C.

Together these 10 provinces were structured by 95 native states depicted as tributaries of the Aztec Empire in the Codex Mendoza. These states were composed of smaller segments or parts (parcialidades) dotting an intricate political landscape, likely comprising between 1,000 to 2,000 settlements of varying sizes that remain to be studied.

More interestingly, its appropriation and use by indigenous communities has not received proper
archaeological attention. In this paper I analyze the adoption of royal Spanish heraldry by Nahua political systems (altepetl) during the Colonial period, from the sixteenth to the eighteenth centuries. My primary goal is to understand the context, meaning, and social
practices for three late colonial banners from eastern Guerrero—the Lienzos de Chiepetlan IV, V, and VI. I argue that these three banners
can be treated as moveable pieces of a complex heraldic ensemble to form the full ornamented coat of arms of the Spanish king. These three banners permit us to compare and contrast indigenous narratives of allegiance and resistance to Spanish imperialism.

As a city represents the spirit of the Aztecs, as well as the most refined expression of Mesoamerican urbanism.
