Hansen Abstract Popular fi lm depictions of varied cultures, ranging from the Chinese, Africans, and Native Americans have repeatedly provided a variant perception of the culture. In works of fi ction, this fl aw cannot only provide us with entertainment, but with insights and motives in the ideological, social, or economic agendas of the authors and/or directors as well as those of the critics. Mel Gibson’s Maya epic Apocalypto has provided an interesting case study depicting indigenous warfare, environmental degradation, and ritual violence, characteristics that have been derived from multidisciplinary research, ethnohistoric studies, and other historical and archaeological investigations. The fi lm received extraordinary attention from the public, both as positive feedback and negative criticism from a wide range of observ- ers. Thus, the elements of truth, public perception, relativism, revisionism, and emic/etic perspectives coalesced into a case where truth, fi ction, and the virtues and vices of the authors and director of the fi lm as well as those of critics were exposed.

  • Banco De México Pre-Columbian Series
    Banco De México Pre-Columbian Series Of NCLT Coins, 1992 – 1998 By Don Bailey 1 THE PRE-COLUMBIAN COINAGE PROGRAM OF MEXICO At the American Numismatic Association's Convention in Baltimore on July28, 1993 The Banco de Mexico held a press conference to announce the beginning of a new commemorative coinage program. This new program would be known as "The Pre-Columbian Coin program". This event was to coincide with the 500th anniversary of Christopher Columbus discovery of the Americas in 1492. This series of commemorative coins will honor six Pre - Columbian civilizations: the Aztec, Central Veracruz, Mayan, Olmec, Teotihuacan, and the Toltec cultures. The first series released in 1992 was to honor the Aztecs. This culture originated in the northern part of Mexico at Aztlan, what is now known as Arizona and Sonora. This Nahuatl speaking tribe referred to themselves as the Mexica or Teochca. In the 13th century after a century of nomadic wandering settled on small islands in Lake Texcoco. In 1325 they created the city known as Tenochtitlan, which is now Mexico City. In the 15th century the Aztecs were only exceed in size by the Incas in Peru. This culture reflected of a highly specialized society with expanded trading, an imperial administration and an agricultural economy. This Aztec Empire ceased to exist when Cuauhtemoc died. He ruled of the Aztecs in 1521 during the siege of Tenochtitlan and led the fight against Herman Cortes and his Spanish conquistadors. Surrendering after weeks of street fighting, Cuauhtemoc was tortured and put in prison. Later Cortes hanged him on his march to Honduras.

    Mexico - Air Pollution and Ancient Cultures UWinteriM 2018: January 2 - 18 Mexico UWinteriM 2018 Study Abroad Syllabus page 1 Mexico - Air Pollution and Ancient Cultures - UWinteriM 2018 In the 8th offering of this exciting course, students travel to five exotic locations in southern Mexico. We'll visit amazing archaeological sites, world-class museums, and universities. We begin in Teotihuacán, the City of the Gods, just outside Mexico City, home to the third largest pyramid in the world (yes, you can climb it!). From there we travel to El Tajín, an impressive Gulf Coast site where ancient ballgames ended in human sacrifice. Next up is Monte Alban, an ancient city where the Zapotec civilization flattened an entire mountaintop using only hand tools. Monte Alban is just outside Oaxaca, an unforgettable place with a wonderful mixture of indigenous and modern cultures. After Oaxaca it's on to Palenque, an ancient Mayan site deep in the jungle, with toucans and howler monkeys to keep us company. We’ll finish the course in Ciudad del Carmen and the Universidad Autónoma del Carmen. We are going to these amazing places to study the effects of acid rain on cultural heritage sites. Ancient structures such as pyramids and their once-colorful stucco coverings are easily damaged by acid rain. In the developing countries of Latin America, efforts to protect these sites from environmental corrosion are in their early stages. Students will examine firsthand the relationships between meteorology, air pollution, and cultural heritage. Joint activities with Mexican university students will increase the value (and fun) of the experience.

  • Young Speakers of Mexican Indigenous Languages: Contesting Language Ideologies and Policies
    Young speakers of Mexican indigenous languages: contesting language ideologies and policies Thesis submitted in accordance with the requirements of the University of Liverpool for the degree of Doctor in Philosophy by Lucia Tina Brandi August 2018 1 Declaration This work is original and has not been submitted previously in support of any degree, qualification or course All sentences and passages quoted from published sources have been specifically acknowledged by referencing to author, work and page(s). ---------------------------------------------------------------------------------------- Lucia Brandi 2 Abstract Young speakers of Mexican indigenous languages: contesting language ideologies and policies In Mexico, the institutionalisation of language rights is reconfiguring discourses of indigeneity. Cultural and linguistic diversity are increasingly reframed as national patrimony, and generic notions of indigeneity firmly embedded into national identity. While such discourses coincide with global concern at language endangerment, they are better contextualised as policy responses to social unrest which, from the late 20th century onwards, has been effective in instrumentalising linguistic and cultural identity as a mobilising factor. This study is set in the highlands of central Mexico, in a stronghold of indigenous Totonac language and culture, and moreover, with a unique and recent history of social and cultural mobilisation. The study deconstructs prevailing language ideologies and policies, and analyses how local language management,

  • Homegardens and the Dynamics of Totonac Domestic Groups in Veracruz, Mexico
    Ana Lid del Angel-Pérez: Homegardens and the dynamics of Totonac domestic groups in Veracruz, Mexico Homegardens and the dynamics of Totonac domestic groups in Veracruz, Mexico Ana Lid del Angel-Pérez Instituto Nacional de Investigaciones Forestales Agrícolas y Pecuarias, [email protected] Abstract The Totonac are an ethnic group that have used homegardens as a strategy for production and social reproduction since pre-colonial Mexico. These homegardens, associated with a family dynamic exhibiting various stages of the domestic group cycle, are flexible elements that allow them to adapt to changing environmental conditions. Fieldwork in the Totonac area suggests that several types of homegardens are associated with different stages of the domestic group cycle. The author concludes that it is not convenient to approach the study of homegardens only through production logic, as this prevents observing the dynamics within them and perceiving their relationship with the organisation of everyday life and the domestic group reproduction in a changing context and with different styles of adaptation, resilience, storage, reprocessing and cultural continuity. KEYWORDS: Culture, nuclear families, extensive families, survival strategies, social reproduction Introduction Since precolonial times, the region inhabited by the Totonac people has encompassed the Central Gulf Coast of Mexico, from the coastal plain to the foothills of the Sierra Madre Oriental mountain range. This region is part of the Mesoamerica geographical-cultural area, where the original people living there share certain cultural, material and ideological features (Ochoa et al. 1999 70). During the classical period (600–900 AD), the town of El Tajin emerged as the most prominent cultural and economic center, until it was abandoned due to Toltecan- Chichimecan invasions (Manzanilla 1999: 168).

Zuelania guidonia is a tree species of cultural importance in Totonac society. This tree is a central element of the Los Voladores (the “flying men”) pre-Hispanic ritual ceremony. However, the populations of Z. guidonia have decreased due to anthropogenic activity. This study aimed to codesign an agroforestry model for the recovery of Z. guidonia populations by combining scientific and traditional agroforestry knowledge at the El Tajín archaeological site in Veracruz, Mexico. We assessed the abundance of Z. guidonia and analyzed plant species richness and diversity in forest fragments. Species were classified according to plant regeneration modes (light-demanding and shade-tolerant) and to the local uses of secondary forests and conserved forest fragments. In addition, we worked collaboratively in a project that consisted of workshops, focus groups, open interviews, drawings, and field walks with community members. We studied a small population of Z. guidonia and recorded 116 woody species.
