We know a good deal about the events that led to the conquest of Yucatan by these foreigners, and the subsequent replacement of their state by a resurgent but already decadent Maya culture, for we have entered into a kind of history, albeit far more shaky than that which was recorded on the monuments of the Classic Period. The traditional annals of the peoples of Yucatan, and also of the Guatemalan highlanders, transcribed into Spanish letters early in Colonial times, apparently reach back as far as the beginning of the Postclassic era and are very important sources. But such annals should be used with much caution, whether they come to us from Bishop Landa himself, from statements made by the native nobility, or from native lawsuits and land claims. These are often confused and often self-contradictory, not least because native lineages seem to have deliberately falsified their own histories for political reasons. Our richest (and most treacherous) sources are the K’atun Prophecies of Yucatan, contained in the “Books of Chilam Balam,” which derive their name from a Maya savant said to have predicted the arrival of the Spaniards from the east.

  • Centeredness As a Cultural and Grammatical Theme in Maya-Mam
    CENTEREDNESS AS A CULTURAL AND GRAMMATICAL THEME IN MAYA-MAM DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Wesley M. Collins, B.S., M.A. ***** The Ohio State University 2005 Dissertation Examination Committee: Approved by Professor Donald Winford, Advisor Professor Scott Schwenter Advisor Professor Amy Zaharlick Department of Linguistics Copyright by Wesley Miller Collins 2005 ABSTRACT In this dissertation, I look at selected Maya-Mam anthropological and linguistic data and suggest that they provide evidence that there exist overlapping cultural and grammatical themes that are salient to Mam speakers. The data used in this study were gathered largely via ethnographic methods based on participant observation over my twenty-five year relationship with the Mam people of Comitancillo, a town of 60,000 in Guatemala’s Western Highlands. For twelve of those years, my family and I lived among the Mam, participating with them in the cultural milieu of daily life. In order to help shed light on the general relationship between language and culture, I discuss the key Mayan cultural value of centeredness and I show how this value is a pervasive organizing principle in Mayan thought, cosmology, and daily living, a value called upon by the Mam in their daily lives to regulate and explain behavior. Indeed, I suggest that centeredness is a cultural theme, a recurring cultural value which supersedes social differences, and which is defined for cultural groups as a whole (England, 1978). I show how the Mam understanding of issues as disparate as homestead construction, the town central plaza, historical Mayan religious practice, Christian conversion, health concerns, the importance of the numbers two and four, the notions of agreement and forgiveness, child discipline, and moral stance are all instantiations of this basic underlying principle.

  • Maya Medicine*
    MAYA MEDICINE* by FRANCISCO GUERRA THE traditional dependence of the European historian on cultural patterns developed by Mediterranean civilizations tends to disregard pre-Columbian achievements in the New World. Our main cultural stream had its source around the 3rd millennium B.C. in the Nile, Euphrates and Indus valleys, when the oldest civilizations developed an agriculture based on artificial irrigation. Egyptians and Hindus worked metals, used beasts of burden and the plough, and established a system of writing; the Sumerians added to all these technical achievements the principle of the wheel. New World Civilizations In that far-off age the American Indians were still migrating southwards and establishing themselves in territories where domestication of maize became possible. To the three great American civilizations-Maya, Aztec and Inca- the wheel, the plough, iron implements, and the use of beasts of burden remained unknown until the arrival of the Europeans, although the Inca made limited use of the llama. A true system of writing going beyond pictographic representation was attained only by the Maya, but the Aztec reached the greatest military and political power without any such advances. Despite these technical limitations the pre-Columbian Americans could claim in a few instances some intellectual superiority over the Old World. The Maya possessed a philosophical outlook on life, a sense of balance, of architectural perfection and an unquestioned mathematical accomplishment which made them, so to speak, the Greeks of the New World. In the same way, the political enterprises of the Aztecs may be compared with those of the Romans; and carrying the simile a step farther we could find a parallel of agressiveness between Incas and Carthaginians.

  • Adoring Our Wounds: Suicide, Prevention, and the Maya in Yucatán, México
    Adoring Our Wounds: Suicide, Prevention, and the Maya in Yucatán, México By Beatriz Mireya Reyes-Cortes A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Anthropology in the Graduate Division of the University of California, Berkeley Committee in Charge: Professor Stanley Brandes, Chair Professor William F. Hanks Professor Lawrence Cohen Professor William B. Taylor Spring 2011 Adoring our Wounds: Suicide, Prevention, and the Maya in Yucatán, México Copyright 2011 by Beatriz Mireya Reyes-Cortes Abstract Adoring Our Wounds: Suicide, Prevention, and the Maya in Yucatán, México By Beatriz Mireya Reyes-Cortes Doctor of Philosophy in Anthropology University of California, Berkeley Professor Stanley S. Brandes The first decade of the 21st century has seen a transformation in national and regional Mexican politics and society. In the state of Yucatán, this transformation has taken the shape of a newfound interest in indigenous Maya culture coupled with increasing involvement by the state in public health efforts. Suicide, which in Yucatán more than doubles the national average, has captured the attention of local newspaper media, public health authorities, and the general public; it has become a symbol of indigenous Maya culture due to an often cited association with Ixtab, an ancient Maya ―suicide goddess‖. My thesis investigates suicide as a socially produced cultural artifact. It is a study of how suicide is understood by many social actors and institutions and of how upon a close examination, suicide can be seen as a trope that illuminates the complexity of class, ethnicity, and inequality in Yucatán. In particular, my dissertation –based on extensive ethnographic and archival research in Valladolid and Mérida, Yucatán, México— is a study of both suicide and suicide prevention efforts.

  • Mayan Medicine: Rituals and Plant Use by Mayan Ah-Men
    MAYAN MEDICINE: RITUALS AND PLANT USE BY MAYAN AH-MEN by Kaylee Doemel Submitted to the Faculty of The Archaeological Studies Program Department of Sociology and Archaeology in partial fulfillment of the requirements for the degree of Bachelor of Science University of Wisconsin-La Crosse 2013 Copyright © 2013 by Kaylee Doemel All rights reserved II MAYAN MEDICINE: RITUALS AND PLANT USE BY MAYAN AH-MEN Kaylee Doemel, B.S. University of Wisconsin-La Crosse, 2013 Mayan civilization is a great example of a culture that was able to live off of the land and thrive using the resources around them. This paper looks at ah-men healers in Classic Mayan societies. It examines the plants and rituals used when curing illnesses and how we can observe this in the archaeological record. Classic Mayan ideology is also looked at in regards to its connection to ah-men and medicine, looking at ah-men's position in society due to the knowledge that they possessed. This paper also examines modern Mayans today and the ancient healing techniques that they practice. With this information, looking at what seemed to work and not work for curing different illnesses in Classic Mayan societies, modern medicine may become more natural, using plants and other resources available to cure illnesses. III ACKNOWLEDGEMENTS I would like to say a special thanks to my thesis advisor Dr. David A. Anderson and my reader Dr. Timothy McAndrews for all the help and encouragement in this process. I would also like to thank my writing group members Brittany Viviani and Kristine Fitzpatrick for all of their help and input while writing this paper.

    Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus .

El incendio de 1998 ha sido considerado como el punto de quiebre para los cambios y tensiones que están ocurriendo actualmente en la región. Método: Se realizaron 66 entrevistas semiestructuradas y a profundidad a pobladores de dos comunidades indígenas ubicadas dentro (Tziscao) y fuera (Antelá) del Parque. Los temas tratados fueron: las experiencias durante el incendio de 1998; las políticas públicas en torno al uso del fuego; y la voz de la comunidad para comprender quiénes son, dónde y cómo se ha producido el nacimiento de los “Sin fuego”.
