CfP EAA Barcelona 2018: Re‐thinking medieval and early modern pestilences from a biosocial perspective: advanced methods and renewed concepts in archaeological sciences

EAA Barcelona 2018 – 5‐8 September 2018
Call for Papers and Posters
Deadline: 15 February 2018
Re‐thinking medieval and early modern pestilences from a biosocial perspective: advanced methods and renewed concepts in archaeological sciences

While contagious diseases have affected the human species since its origins, great medieval epidemics (e.g. plague, leprosy, tuberculosis) have sparked particular interest for decades. In recent years, archaeology has played an increasing role in the scientific study of medieval pestilences, notably by providing reliable data on both the paleobiology of epidemic victims and their burial treatment. Despite the various breakthroughs reached by interdisciplinary research, the study of past epidemics still needs to get improved, particularly through an integrated analysis of biological and social dimensions of these diseases, which are closely interrelated. We invite contributions regarding both recent methodological advances in the retrospective diagnosis of infectious diseases and the output of archaeological sciences on social and cultural factors acting in human populations’ adaptability to these diseases.

The session shall address various questions, among which:
– What are the new lines of research and future perspectives in paleopathological and palaeomicrobiological study of these diseases?
– What information paleobiological data derived from skeletal assemblages can provide on the epidemiological characteristics of the diseases?
– What was the endemicity of diseases in various places, how did they evolve over time, and how did various diseases competed each other?
– How funerary archaeology and textual sources contributes to reappraise the history of these diseases (e.g. attitudes towards the victims in terms of their integration and/or exclusion, depending on the time period and cultural framework)?
– Which methodological implementation would be desirable in the future to allow retrospective diagnosis of still poorly-known diseases (e.g. ergotism)?

EAA Vilnius 2016: Session report on “Plague in diachronic and interdisciplinary perspective”

The following session report by Doris Gutsmiedl-Schümann (Freie Universität Berlin, Germany), Sacha Kacki (Université de Bordeaux, France), Marcel Keller (MPI-SHH Jena, Germany) and Christina Lee (University of Nottingham, UK) will be published in The European Archaeologist. With kind permission of the EAA.

Edit 17-02-07: filmed talks are now linked under the respective name.

Plague, an infectious disease caused by the bacterium Yersinia pestis, occurred in at least three major historical pandemics: the Justinianic Plague (6th to 8th century), the Black Death (1348-1352, with further epidemic outbreaks until the 18th century), and the Modern or Hong Kong Plague (19th to 20th century). However, it appears that the disease may be much older: DNA from Bronze Age human skeleton has recently shown that plague first emerged at least as early as 3000 BC. As any disease, plague has both a biological as well as a social dimension. Different disciplines can therefore explicate different aspects of plague which can lead to a better understanding of the disease and its medical and social implications.

The session was held on 2nd September 2016 as part of the 22nd Annual Meeting of the EAA with the aim of bringing together researchers from different disciplines who work on plague. It addressed a series of research questions, such as:

  • Which disciplines can contribute to the research on plague?
  • What are their methodological possibilities and the limitations of their methodologies?
  • How can different disciplines work together in order to gain a more realistic and detailed picture of plague in different periods and regions?
  • How did different societies react to plague? In which way may we prove or disprove evidence for such reactions – and which disciplines may contribute to the debate?
  • What where the common aspects, and what the differences of the various plague outbreaks? Are there any epidemiological characteristics that are essential and/or unique to plague?
  • What are possible implications of the pandemic spread and endemic occurrence of plague through the ages for the interpretation of historical and cultural phenomena?

Ecological Approaches in Medieval Rural Archaeology

  • R. Schreg, Ecological Approaches in Medieval Rural Archaeology. European Journal of Archaeology 17(1), 2014, 83-119
    DOI 10.1179/1461957113Y.0000000045

    [There is currently no Open Access, sorry!].

In recent years, scientific methods of bio- and geoarchaeology have become increasingly important for archaeological research. Political changes since the 1990s have reshaped the archaeological community. At the same time environmental topics have gained importance in modern society, but the debate lacks an historical understanding. Regarding medieval rural archaeology, we need to ask how this influences our archaeological research on medieval settlements, and how ecological approaches fit into the self-concept of medieval archaeology as a primarily historical discipline. Based mainly on a background in German medieval archaeology, this article calls attention to more complex ecological research questions. Medieval village formation and the late medieval crisis are taken as examples to sketch some hypotheses and research questions. The perspective of a village ecosystem helps bring together economic aspects, human ecology and environmental history. There are several implications for archaeological theory as well as for archaeological practice. Traditional approaches from landscape archaeology are insufficient to understand the changes within village ecosystems. We need to consider social aspects and subjective recognition of the environment by past humans as a crucial part of human–nature interaction. Use of the perspective of village ecosystems as a theoretical background offers a way to examine individual historical case studies with close attention to human agency. Thinking in terms of human ecology and environmental history raises awareness of some interrelations that are crucial to understanding past societies and cultural change. (Abstract)

The article takes the late medieval crisis as an example for the complexity of interaction and proposes to understand the Black Death within the framework of human ecology.

Yersinia pestis – the missing ecological and historical dimension

Reposted from http://archaeologik.blogspot.de/2011/11/yersinia-pestis-missing-ecological-and.html

Yersinia pestis, Direct Fluorescent Antibody Stain (DFA),
200x Magnification
(Centers for Disease Control and Prevention‘s
Public Health Image Library [PHIL],
identification number #1918 [public domain]).
In a recent article a group of German and Canadian researchers presented the genome of Yersinia pestis as it has been extracted from burials of the London East Smithfield burial ground dated to 1348/49 (Bos et al. 2011). This site has been excavated by the Museum of London after it has been localised in 1986 (Grainger et al. 2008).
The article aims at the reconstruction of the ancient genome of Yersinia pestis, as this promises implications for the understanding of infectious diseases, as “genomic data from ancient microbes may help to elucidate mechanisms of pathogen evolution and adaptation for emerging and re-emerging infections”.
The authors conclude:
1.) “Genetic architecture and phylogenetic analysis indicate that the ancient organism is ancestral to most extant strains and sits very close to the ancestral node of all Y. pestis commonly associated with human infection. Temporal estimates suggest that the Black Death of 1347–1351 was the main historical event responsible for the introduction and widespread dissemination of the ancestor to all currently circulating Y. pestis strains pathogenic to humans.” The classic Black Death was quite different from previous epidemics. The authors refer to the Justinian plague “popularly assumed to have resulted from the same pathogen: our temporal estimates imply that the pandemic was either caused by a Y. pestis variant that is distinct from all currently circulating strains commonly associated with human infections, or it was another disease altogether.”
2.) “Comparisons against modern genomes reveal no unique derived positions in the medieval organism, indicating that the perceived increased virulence of the disease during the Black Death may not have been due to bacterial phenotype. These findings support the notion that factors other than microbial genetics, such as environment, vector dynamics and host susceptibility, should be at the forefront of epidemiological discussions regarding emerging Y. pestis infections.”
