Looking back, looking forward: Paleopathology in Andean South America.

Over the past twenty years, the field of Andean paleopathology has advanced significantly thanks to a new generation of scholars who have been attracted to this region and whose innovative research has expanded our knowledge substantially. The papers in this special issue demonstrate how the field of Andean paleopathology has diversified and grown to become what is today a truly interdisciplinary enterprise involving archaeology, ethnohistory, biological anthropology, geochemistry, medical imaging, and genetics. These studies apply theoretical approaches to research questions that are increasingly innovative and nuanced as well as analytical methods that were in their infancy when I wrote my 1997 survey of the field.

A mass sacrifice of children and camelids at the Huanchaquito-Las Llamas site, Moche Valley, Peru.

Here we report the results of excavation and interdisciplinary study of the largest child and camelid sacrifice known from the New World. Stratigraphy, associated artifacts, and radiocarbon dating indicate that it was a single mass killing of more than 140 children and over 200 camelids directed by the Chimú state, c. AD 1450.

Trepanation Procedures/Outcomes: Comparison of Prehistoric Peru with Other Ancient, Medieval, and American Civil War Cranial Surgery.

More prehistoric trepanned crania have been found in Peru than any other location worldwide. We examine trepanation practices and outcomes in Peru over nearly 2000 years from 400 BC to provide a perspective on the procedure with comparison with procedures/outcomes of other ancient, medieval, and American Civil War cranial surgery. Data on trepanation demographics, techniques, and survival rates were collected through the scientific analysis of more than 800 trepanned crania discovered in Peru, through field studies and the courtesy of museums and private collections in the United States and Peru, over nearly 3 decades.

Reprint of-Differential diagnosis: Trepanation.

Trepanation is the scraping, cutting, or drilling of an opening (or openings) into the neurocranium. World surveys reveal that a number of ancient cultures experimented with cranial surgery, and that in some areas these practices continued into modern times. Archaeological discoveries of possible trepanations continue to be made, often from geographic areas or time periods from which the practice was not previously known.

Craniofacial plasticity in ancient Peru.

Numerous studies have utilized craniometric data to explore the roles of genetic diversity and environment in human cranial shape variation. Peru is a particularly interesting region to examine cranial variation due to the wide variety of high and low altitude ecological zones, which in combination with rugged terrain have created isolated populations with vastly different physiological adaptations. This study examines seven samples from throughout Peru in an effort to understand the contributions of environmental adaptation and genetic relatedness to craniofacial variation at a regional scale.

Violence and weapon-related trauma at Puruchuco-Huaquerones, Peru.

Conquest of indigenous peoples in North America is understood primarily through ethnohistorical documents, archaeological evidence, and osteological analyses. However, in the Central Andes, the colonial enterprise and its effects are understood only from postcontact historical and ethnohistorical sources. Few archaeological and bioarchaeological studies have investigated Spanish Conquest and colonialism in the Andean region [for exceptions see Klaus and Tam: Am J Phys Anthropol 138 (2009) 356-368; Wernke, in press; and Quilter, in press].

Chapter 1: ancient trepanation.

Cranial trepanations began to be performed more than 5000 years ago in Europe and as early as the 5th century BC in the New World. It was only in the mid-19th century, however, that men of medicine began to realize that the openings in some of the unearthed ancient skulls were made by individuals skilled in surgery, and that the practice was routinely performed on the living. Some of the first reports on these unusual skulls and their significance came from pioneer neurologists and neurosurgeons, including Paul Broca and Victor Horsley.

Prehistoric trepanation in the Cuzco region of Peru: a view into an ancient Andean practice.

In this study, patterns of prehistoric trepanation in the southern highlands of Peru were examined through an analysis of 11 Cuzco-region burial sites. Trepanations were found in 66 individuals, with several individuals exhibiting more than one trepanation, for a total of 109 perforations observed. The predominant methods used were circular cutting and scraping-methods that proved highly successful with an overall 83% survival rate and little ensuing infection.

Biodistance analysis of the Moche sacrificial victims from Huaca de la Luna plaza 3C: Matrix method test of their origins.

The purpose of this study is to test two competing models regarding the origins of Early Intermediate Period (AD 200-750) sacrificial victims from the Huacas de Moche site using the matrix correlation method. The first model posits the sacrificial victims represent local elites who lost competitions in ritual battles with one another, while the other model suggests the victims were nonlocal warriors captured during warfare with nearby polities. We estimate biodistances for sacrificial victims from Huaca de la Luna Plaza 3C (AD 300-550) with eight previously reported samples from the north coast of Peru using both the mean measure of divergence (MMD) and Mahalanobis' distance (d2).

Mummified trophy heads from Peru: diagnostic features and medicolegal significance.

Several forms of mummified human trophy heads were produced by prehistoric and historic native groups in South America. This paper describes the diagnostic features of trophy heads produced by the Nasca culture of ancient Peru. A growing interest in these mummified heads among collectors of Pre-Columbian art and antiquities has led to their illegal exportation from Peru, in violation of national and international antiquities laws.
