Of plagues,planes and politics: Controlling the global spread of infectious diseases by air

In recent years, the implications of globalisation for the spread of infectious diseases has begun to emerge as an area of concern to political geographers. Unsurprisingly, much of the contemporary literature focuses on the multifarious threats posed by human and, increasingly, non-human mobility. Prompted by current geopolitical concerns surrounding the public health implications of regular international air travel, this paper extends such research by exploring the ways in which the technology of the aeroplane stimulated the production of new international sanitary initiatives aimed at safeguarding global public health in an era of mass aeromobility. By tracing the development of sanitary regulations for aerial navigation, from their origins in the 1920s through the twentieth century in particular, we document the emergence of a series of public health interventions that were designed to limit the public health threat associated with increased international air travel and the concomitant rise in the mobility of infectious diseases. From inoculation certificates to quarantine and the routine ‘disinsection’ of passenger aircraft with powerful insecticides, modern air travel is replete with a complex set of procedures designed to lessen the risks associated with flying between different climatic and ecological zones. Our detailed examination of the historical context in which these procedures were devised and implemented leads us to consider the importance of time and space, power and efficacy, to the development of a more nuanced understanding of the shifting public health response to an increasingly fluid, mobile, and inter-connected society.     

Locating the Harbour: Myos Hormos/Quseir al-Qadim: a Roman and Islamic Port on the Red Sea Coast of Egypt

Recent maritime investigations at Quseir al-Qadim, on the Red Sea coast of Egypt, have revealed the importance of this port in both the Roman and later Islamic periods. This paper outlines the key evidence for the location of the harbours, from survey, sedimentological analysis and selective excavation. The Roman harbour, occupied between the 1st century BC and the 3rd century AD, was located in a now-silted lagoon. Over 100 sedimentological cores indicated its siltation process. By the time the site was reoccupied in the 12th century AD, the harbour was reduced to a small bay at the entrance to the former lagoon.

Fiat Lux: Functional Analysis of Three Saxo-Norman Pottery Lamps from Berkeley,Gloucestershire

THIS PAPER COMPRISES analysis of three Saxo-Norman pottery lamps recovered during archaeological excavations in 2012 in the Edward Jenner Museum garden, Berkeley, Gloucestershire. While such vessels have been known to archaeologists since the earliest days of Saxon and medieval pottery studies, their specific function, other than general ‘lighting’, has never been considered. Similarly, the composition of the fuel in such lamps has not been scientifically verified. In the following paper, both of these areas are addressed through experimental archaeology and organic residue analysis. The conclusion reached is that the lamps were chosen for use in a late-Saxon industrial workshop as they were ideal for the setting, providing a consistent, stable and bright light source in comparison with other available lighting methods of the period.     

Dendrochemical analysis of a tree-ring growth anomaly associated with the Late Bronze Age eruption of Thera

The most marked tree-ring growth anomaly in the Aegean dendrochronological record over the last 9000 years occurs in the mid 17th century BC, and has been speculatively correlated with the impact of the Late Bronze Age eruption of Thera (Santorini). If such a connection could be proved it would be of major interdisciplinary significance. It would open up the possibility of a precise date for a key archaeological, geological and environmental marker horizon, and offer a direct tie between tree-ring and ice-core records some 3600 years ago. A volcanic explanation for the anomaly is highly plausible, yet, in the absence of a scientifically proven causal connection, the value of the proposed correlation is limited. In order to test the hypothesis, dendrochemical analysis via Synchrotron Radiation Scanning X-ray Fluorescence Microscopy (SXFM), Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was carried out on growth-ring series from four trees displaying the anomaly. Increases of sulfur, calcium, and rare earth elements following the onset of altered growth, plus concentration spikes of zinc and hafnium in the first affected growth-ring provide promising new evidence in support of a volcanic causal factor. Although a volcanic association is implied, the new data are not sufficient to prove a link to the exact eruption source.
