Human biology in the Classic Maya collapse: Evidence from paleopathology and paleodiet

We review evidence from human biology—paleopathological and isotopic paleodietary studies on ancient Maya skeletons—to assess the validity of ecological models of the Classic Maya collapse, in which elevated disease and deteriorating diet are commonly assumed. To be upheld, the health arguments of ecological models require that the Maya disease burden (1) was greater than that for many other societies and (2) increased over the span of occupation. The dietary argument requires (1) consistent change in diet from Preclassic and Early Classic Periods to the Terminal Classic and (2) increasing social divergence in diet. A correlation between diet and disease is necessary to link these arguments. Neither pathology nor isotopic data consistently support these criteria. Instead, it appears that local environmental and political factors created diversity in both disease burden and diet. In view of the human biological data, we are skeptical of ecological models as generalized explanations for the abandonment of Classic Maya sites in the southern lowlands.     

How Was Edmond Halley’s Map of Magnetic Declination (1701) Constructed?

Edmond Halley made two scientific voyages in the Atlantic Ocean as captain of the HMS Paramore between 1698 and 1700. Following these voyages he published the first map showing lines of equal magnetic declination in 1701. Halley did not reveal how he constructed the map, however, and it remains unknown. In this study, a construction procedure is hypothesized that uses mathematical tools that were available in his day, namely arithmetical averages and Isaac Newton’s method of divided difference for fitting a polynomial curve to data. To enable his map construction, a method is suggested whereby Halley could have created new data to augment the situations where insufficient data were collected.     

Kings and commoners at Copan: Isotopic evidence for origins and movement in the Classic Maya period

Eight human interments were excavated in the 1990s beneath the Acropolis at the Classic Maya site of Copan in Honduras, which was the capital of a Maya kingdom from ca. AD 400 to 800. These human remains come from both royal tombs and less elaborate burials dating to the early part of this period and lie deep in the accumulated architectural layers of the Acropolis. We present a brief summary of the context, contents, and external links represented by these interments. Several lines of evidence point to connections between early Copan and Teotihuacan in the Central Highlands of Mexico, and Tikal in the central Maya lowlands of the Petén in Guatemala.     

Recent Progress in Bioarchaeology: Approaches to the Osteological Paradox

The publication of The Osteological Paradox (Wood et al., 1992, Current Anthropology, 33:343–370) a decade ago sparked debate about the methods and conclusions drawn from bioarchaeological research. Wood et al. (1992, Current Anthropology, 33:343–370) highlighted the problematic issues of selective mortality and hidden heterogeneity in frailty (susceptibility to illness), and argued that the interpretation of population health status from skeletal remains is not straightforward. Progress in bioarchaeology over the last few years has led to the development of tools that will help us grapple with the issues of this osteological paradox. This paper provides a review of recent literature on age and sex estimation, paleodemography, biodistance, growth disruption, paleopathology, and paleodiet. We consider how these advances may help us address the implications of hidden heterogeneity in frailty and selective mortality for studies of health and adaptation in past societies.     

Goble,Andrew Edmund,Confluences of Medicine in Medieval Japan： Buddhist Healing,Chinese Knowledge,Islamic Formulas,and Wounds of War

This PhD thesis deals with the infamous plundering of the Imperial garden Yuanmingyuan in the wake of the British-French capture expedition of 1860. The approach and the strategies of the British and French actors involved are described from a micro-perspective. In the nineteenth century, plundering took center stage in a number of actions by colonial armies worldwide, as discussed by the author, Ines Eben v. Racknitz.     

Microbiology of Concretions, Sediments and Mechanisms Influencing the Preservation of Submerged Archaeological Artifacts

Research conducted at deep-ocean ship wreck sites in the North Atlantic Ocean, the Mediterranean Sea and in the Gulf of Mexico have revealed that microorganisms play a significant role in both the preservation and loss of submerged artifacts. Research to be reported concentrates on the influence of microbiologically induced concretions on the survival of maritime artifacts. Rusticles, a common form of concretion, have been found to provide valuable information to archeology (Garzke et al. 1997, Proceedings of the Society of Naval Architects and Marine Engineers). The role of rusticles in the preservation of recalcitrant materials such as coal and glass fragments that become embedded within these growths, as well as forensic chemical analysis can be used to determine the nature of goods or munitions being carried by the ship at the time of its sinking, and will form examples.
