Academic literature on the topic 'Aztec chronology'

AbstractArchaeologists working in the Basin of Mexico have long accepted a chronology in which sequential ceramic phases (Metepec, Coyotlatelco, Mazapan, Aztec I, and Aztec II) define the period between the last stages of Classic Teotihuacan and the immediate antecedents of Late Postclassic Tenochtitlan. The absolute chronology of these phases has remained tentative, and there have been hints of possible temporal overlap between some of them. A series of 37 new radiocarbon dates from three deep, stratified sites in the Basin of Mexico suggest (1) that the traditional sequence of phases is essentially valid; (2) that both Coyotlatelco and Aztec I may have begun significantly earlier than traditionally believed; (3) that there may have been partial chronological overlap between Late Coyotlatelco and Early Aztec I in some parts of the basin; (4) that there was probably little significant temporal overlap between Aztec I and Aztec II; and (5) that the ethnohistorically recognized sociopolitical complexity of the long era in question is amply reflected in a regional ceramic sequence that still requires considerable refinement in both time and space.

AbstractThis article offers a revision of the chronology and settlement history of Tula, Hidalgo, synthesizing information obtained from numerous investigations and 68 radiocarbon and seven archaeomagnetic dates. Tula Chico's earliest settlement appeared while the region was under the control of Teotihuacan as one of many hilltop Coyotlatelco settlements in the region. The monumental center at Tula Grande did not appear until after Tula grew to power, presumably with the consolidation of the other Coyotlatelco polities. Extensive exposure of residential structures in numerous localities have revealed a widespread pattern of barrios containing households exhibiting a wide range of social status that enjoyed access to a wide variety of luxury items including the first reported objects of gold. Tula Grande and the Tollan phase city appear to have already been abandoned and in ruins prior to the arrival of Aztec II peoples. The Late Aztec period occupation shows a preoccupation with Tula's ruins that parallels similar evidence from the Templo Mayor excavations suggesting it was indeed the place the Aztecs called Tollan.

AbstractThe Aztec city-state of Otumba is the focus of a long-term project of archaeological investigation. Analysis of surface and excavated ceramics and obsidian-hydration dates for the capital—Otumba—indicate a dispersed Mazapan occupation, a scattered early Aztec (Aztec II) occupation, and an intense Late Aztec (Aztec III) and Early Colonial (Aztec III/IV) occupation. In the paper we incorporate recent radiocarbon dates to refine the local late Postclassic chronology. A cluster of hydration dates suggests the early (Mazapan) occupation starts ca. a.d. 900. Aztec II ceramics, which are widely distributed in surface artifact collections, may begin as early as a.d. 1200 and continue until a.d. 1400, overlapping Aztec III ceramics, which we have dated from a.d. 1350 ± 50 to 1521 and later. Otumba continued to have a substantial occupation until ca. a.d. 1600/1620 in the early seventeenth century, when most of the Aztec town was abandoned.

We describe the development of a new chronology for the Postclassic site of Calixtlahuaca, Toluca, Mexico. We identify three ceramic phases using discriminant analysis of decorated and plainware types. These phases are consistent with excavated stratigraphy, as well as a series of 54 radiocarbon dates. We then assign absolute dates to the phases using Bayesian analysis of radiocarbon dates and historical information on the date of site abandonment. The resulting chronology identifies three phases at the site: Dongu (A.D. 1130-1380), Ninupi (A.D. 1380-1450), and Yata (A.D. 1450-1530). We then discuss the local and regional implications of the chronology. More broadly, our results demonstrate the utility of using multiple, complementary methods for developing more precise chronologies.

In this paper, we present a complete list of eclipses documented in the Mexica manuscripts. We use this list together with information in the chronicles to outline a possible method used by Mexica chronologists for linking historical with retrodictable cosmic events that were deliberately chosen to fit historical circumstances. Solar events, particularly eclipses, figure prominently in a scheme that stresses the recurrence of like-in-kind events positioned at multiples of the Xiuhmolpilli (52-year) cycle. Thus, both the foundation of the empire and calendrical adjustments related to the fictional chronology of World Ages are connected to eclipses that were visible at Tenochtitlan and that fell either at the solstices or the equinoxes.

AbstractTo begin the discussion, I propose distinctions between four archaeological approaches to time. I call these clock time, phase time, social time, and characterization. Main points in the other papers are that Postclassic phases tend to be a century or more earlier than recently thought, that Aztec I may be much earlier than thought, and that there may be considerable temporal overlap among Postclassic phases. The evidence is fairly good for the first of these points, but less clear for the other two—more data are needed. I propose a slightly revised Teotihuacan chronology and mention some issues about the nature of the Teotihuacan to post-Teotihuacan transition.

Raised field agriculture in the Basin of Mexico was a highly sustainable farming method that did not depend upon centralised political control. Study of thechinampasystem around the Early and Middle Postclassic city of Xaltocan through a combination of remote sensing, GIS, targeted excavation and AMS dating has revealed an extensive area of raised fields that was abandoned when Xaltocan was conquered by an alliance of powerful neighbours during the fourteenth century AD. The rise and abandonment of the chinampa system were thus directly linked to the political economy of the city-state. The failure to revive the raised field systems in the following Aztec period can also be attributed to the impact of political, economic and ecological factors.

Kyi, Tanya L. Seeing Red: The True Story of Blood. Illus. Steve Rolston. Toronto: Annick Press, 2012. Print. Seeing Red is an informative, humourous, gory, and decidedly irreverent treatment of a subject close to all of our hearts. Canadian author Tanya Lloyd Kyi is best known for the 50 Questions series for young readers, featuring topics as diverse as fire, poison and underwear. The very clever illustrations, by award-winning comic and graphic novel artist Steve Rolston, are presented in shades of black, grey, and (naturally) blood red. The main narrative provides a fascinating overview of the red stuff, human and otherwise, and the central role it has played in history, culture, and science. Alongside the text in each chapter, the reader is treated to a comic book featuring (in a nod to Bram Stoker) a boy named Harker who keeps a notebook of his blood-filled adventures as he finds himself at the centre of the topic under discussion. And throughout, the author provides a wealth of related trivia and factoids using insets on subtle background graphics of red blood cells and band aids. Individual chapters focus on ritual and religion, coming of age, food and drink, family ties and genetics, medicine and forensics, and the human fascination with violence. And while not following a strict chronology, the author clearly demonstrates how human understanding of this vital fluid has developed throughout history. The chapter Rites of Passage should be of particular interest to pre-teens, with its graphic descriptions of how various cultures have developed painful and bloody initiation rituals to mark a boy’s transition to adulthood, and of the wide range of celebrations and taboos surrounding a girl’s first menstrual period. The ever-popular vampire is featured no more prominently than any other topic in the text, with only a couple of sections in the chapter Sips and Suppers that discusses the utility of blood in all manner of drinking and dining. But the introduction of a cute young female vampire to Harker’s story midway through the book will no doubt appease any disappointed Twilight fans. Pop culture references abound, and the author’s black humour skewers major religions and historical figures alike. A discussion of hemophilia features an illustration of Queen Victoria handing a jumbo pack of bandages to her daughter with the words “Don’t forget your dowry dear.” There’s no lack of gory detail in this book, from Aztec priests ripping beating hearts from the chests of their captives, to classifications of blood spatter velocities and how they correspond to different levels of violent injury. This book would be a great addition to any public or school library. Each chapter ends with a few questions from Harker’s notebook that may provide some interesting starting points for classroom discussion: “Is it okay to sacrifice animals for religious reasons? How is that different than killing for meat, or hunting for sport?” The reader is provided with a list of titles for further reading, and a selected bibliography. And with its fairly in-depth indexing, Seeing Red provides a handy reference to a lot of bloody information.
