1.1 Prologue What is archaeomineralogy? The term has been used at least once before (Mitchell 1985), but this volume is the first publication to lay down the scientific basis and systematics for this subdiscipline. Students sometimes call an introductory archaeology course "stones and bones." Archaeomineralogy covers the stones component of this phrase. Of course, archaeology consists of a great deal more than just stones and bones. Contemporary archaeology is based on stratigraphy, geomorphology, chronometry, behavioral inferences, and a host of additional disciplines in addition to those devoted to stones and bones. To hazard a definition: archaeomineralogy is the study of the minerals and rocks used by ancient societies over space and time, as implements, orna ments, building materials, and raw materials for ceramics and other processed products. Archaeomineralogy also attempts to date, source, or otherwise char acterize an artifact or feature, or to interpret past depositional alteration of archaeological contexts. Unlike geoarchaeology, archaeomineralogy is not, and is not likely to become, a recognized subdiscipline. Practitioners of archaeomineralogy are mostly geoarchaeologists who specialize in geology and have a strong background in mineralogy or petrology (the study of the origin ofrocks).

This manual pulls together—and illustrates with interesting case studies—the variety of specialized and generalized archaeological research strategies that yield new insights into science. Throughout the book there are templates, consisting of questions, to help readers visualize and design their own projects. The manual seeks to be as general as possible, applicable to any society, and so science is defined as the creation of useful knowledge—the kinds of knowledge that enable people to make predictions. The chapters in Part I discuss the scope of the archaeology of science and furnish a conceptual foundation for the remainder of the book. Next, Part II presents several specialized, but widely practiced, research strategies that contribute to the archaeology of science. In order to thoroughly ground the manual in real-life applications, Part III presents lengthy case studies that feature the use of historical and archaeological evidence in the study of scientific activities.

Nanotechnology is sweeping the world. This science of very small particles, which includes genetic modification and the reconfiguring of the arrangement of atoms, presents possibilities beyond imagination. It also has huge implications for all South Africans, especially at home. How exactly is this new technology playing out in South Africa? In countries like India, nanotechnology is being supported as a source of income and innovation. It has the potential to improve both the human condition and a countrys productivity and competitiveness. Is South Africa doing what it should and could to foster nanotechnology and biotechnology, and to advance bioeconomies within the country? And what does the new technology mean for us as consumers? How many of us know that this technology is already being employed in substances like suntan cream and lipstick, with potential health implications for users? The application of nanotechnology poses risks as well as huge benefits, so we need to be particularly vigilant of the ethics and dangers of it. This book provokes discussion around these important topics and relays eyeopening information to those of us who thought all of this was sci-fi.

The present volume comprises aspects of both basic and applied limnology. They include works on physical, chemical, and biological limnology, as well as experimental approaches in selected areas. Contributions from investigators regarding aquatic conservation and biodiversity were specifically not available and therefore, these aspects are considered in various included works. Most manuscripts deal with lentic aquatic resources. This is not surprising since Mexican limnology followed the general study trend of that from temperate limnology. Despite this, we must emphasize that lotic resources in Mexico are quite important both locally and regionally. This does not mean that rivers are not under limnological research in Mexico, just that their study has only recently begun. It is the intention of the volume to stimulate a larger section of limnologists to further research in this field. It is to be hoped that policy-framing governmental authorities in Mexico will benefit from it, and consider some of the aspects described so that further damage to the epicontinental waterbodies can be halted, and remedial measures can be considered in the future.

Conceived as a contribution to the continuous construction of the identity of the Codex Mendoza, the present volume is organized around three axes: material analysis, textual and stylistic interpretation, and reception and circulation studies. The works of Barker-Benfield and MOLAB further our objective of understanding the manuscript's materiality. The re-binding and conservation process registered by Barker-Benfield has allowed us to do away with speculation regarding the method of production used to create the manuscript and its previous bindings. This, in turn, has allowed heretofore accepted connections, such as the authorship of Francisco Gualpuyogualcal, to be reexamined. Similarly, the analysis undertaken by the MOLAB team and headed by Davide Domenici has settled the debate on the nature of the pigments used in the production of the manuscript. This has added additional layers of nuance to previously held interpretative hypotheses on the meaning of specific pigments and the strictness of their application in the tlacuilolli. While color holds meaning for the tlacuilo, color is not inexorably linked to its materiality. These observations have the potential to inspire a new generation of interpretative studies, based on ever more accurate data regarding the material nature of the Codex Mendoza. Interpretative studies of the manuscript in this volume represent a line of inquiry that, by considering the manuscript from the complex perspectives of the work of art, literature, and bibliography, complement previous anthropological and historical readings of the Codex Mendoza. My essays as well as those by Diana Magaloni and Daniela Bleichmar reconsider the number and style of the artists who produced the manuscript in order to understand both the process by which it was created as well as the place it occupies in the artistic context of the early viceroyalty. Far from entering a binary relation between subjugator and subjugated, the decisions made by these artists and intellectuals manifest the forms of thinking and seeing time and space in the Mesoamerican world. I demonstrate that the pictures in the Codex Mendoza were painted in a workshop in which one, two, or more individuals collaborated on each page to create a single composition; as such, the creation of these pictures took on an air of rituality and functioned as "an instrument to recreate, reactualize, and make coherent the historical becoming linked to territory with cosmic patterns" (Magaloni, this volume). This last observation complements and reinforces Joanne Harwood's proposed reading of the third section of the manuscript. For Harwood, notwithstanding the originality of the visual solutions used to compose this section of the manuscript, the Codex Mendoza's pre-Columbian model resonates with a Mesoamerican religious genre: the teoamoxtli.

This Handbook provides a transnational reference point for critical engagements with the legacies of, and futures for, global archaeological collections. It challenges the common misconception that museum archaeology is simply a set of procedures for managing and exhibiting assemblages. Instead, this volume advances museum archaeology as an area of reflexive research and practice addressing the critical issues of what gets prioritized by and researched in museums, by whom, how, and why. Through twenty-eight chapters, authors problematize and suggest new ways of thinking about historic, contemporary, and future relationships between archaeological fieldwork and museums, as well as the array of institutional and cultural paradigms through which archaeological enquiries are mediated. Case studies embrace not just archaeological finds, but also archival field notes, photographic media, archaeological samples, and replicas. Throughout, museum activities are put into dialogue with other aspects of archaeological practice, with the aim of situating museum work within a more holistic archaeology that does not privilege excavation or field survey above other aspects of disciplinary engagement. These concerns will be grounded in the realities of museums internationally, including Latin America, Africa, Asia, Oceania, North America, and Europe. In so doing, the common heritage sector refrain 'best practice' is not assumed to solely emanate from developed countries or European philosophies, but instead is considered as emerging from and accommodated within local concerns and diverse museum cultures.

Mesoamerican communities past and present are characterized by their strong inclination toward color and their expert use of the natural environment to create dyes and paints. In pre-Hispanic times, skin was among the preferred surfaces on which to apply coloring materials. Archaeological research and historical and iconographic evidence show that, in Mesoamerica, the human body—alive or dead—received various treatments and procedures for coloring it. Painting the Skin brings together exciting research on painted skins in Mesoamerica. Chapters explore the materiality, uses, and cultural meanings of the colors applied to a multitude of skins, including bodies, codices made of hide and vegetal paper, and even building “skins.” Contributors offer physicochemical analysis and compare compositions, manufactures, and attached meanings of pigments and colorants across various social and symbolic contexts and registers. They also compare these Mesoamerican colors with those used in other ancient cultures from both the Old and New Worlds. This cross-cultural perspective reveals crucial similarities and differences in the way cultures have painted on skins of all types. Examining color in Mesoamerica broadens understandings of Native religious systems and world views. Tracing the path of color use and meaning from pre-Columbian times to the present allows for the study of the preparation, meanings, social uses, and thousand-year origins of the coloring materials used by today’s Indigenous peoples.
