Discovering the antipodes

Recent work on the past of Australia and New Zealand is surveyed in terms broadly relevant to the many evolving geographies of European settlement overseas since the eighteenth century. Although there was uncertainty about the future of historical geography in the antipodes during the late 1960s, a good deal has been accomplished in the last six years. Recent work has been strongly empirical as historical geographers, and others, have sought to understand the complexity of local development. In this process of discovery, there are immense possibilities for further work. New questions asked of new sources, incisive analyses and thoughtful syntheses will reveal much about the development of society and setting in these outposts of nineteenth-century European expansion.     

Perforated shell and stone objects from Sharm

A group of six shell and four stone perforated objects is examined with a view to determining their function. Several possibilities are suggested as a result of a number of parallels in southeastern Arabia.     

Destruction of microstructure in archaeological bone: a case study from Portugal

Sampling of archaeological human bone may not be justified, contrary to former high expectations regarding adult age assessment based on histomorphometry. The alterations in buried bone as a result of bacterial action are readily visible in the scanning electron microscope (SEM). An understanding of the chemical and structural changes to cortical bone requires work at the level of a few microns. This paper reports on problems encountered during analyses of samples of human bone from Mesolithic (ca. 8000 calbp) shell midden sites at Muge in central Portugal, and the methods used to try and overcome these problems. We believe we have shown that these Mesolithic bones are partly comprised of bacterially reprecipitated mineral, which has had collagen removed, with consequent obliteration of bone microstructure. We conclude that microbial destruction of the structure of archaeological bone can be a serious impediment to analysis of the characteristics of the population represented by those skeletal remains.

Three-dimensional visibility analysis of architectural spaces: iconography and visibility of the wall paintings of Xeste 3 (Late Bronze Age Akrotiri)

In recent years various methods of visibility analysis have been applied to investigate human engagement, experience and socialisation within historic and prehistoric ’natural’ and built environments. On many occasions these approaches appear to be either extremely limited or wholly inadequate for the interpretation of complex built structures and building interiors because they do not fully model the three-dimensional geometry of such spaces. This paper briefly reviews computational approaches to visual analysis that have been previously applied in archaeological research, and then goes on to introduce a new analytical technique that uses fully 3D reconstructions of past environments. This method integrates common functionalities of 3D modelling software and Geographic Information Systems (GIS), essentially permitting viewshed analysis to be performed upon objects of any form and shape modelled in 3D. We argue that the proposed methodology can generate new data and encourage fresh lines of enquiry in the study of extant and partially preserved historic and prehistoric built structures in a variety of contexts, ranging from building interiors and townscapes to landscapes. The potential of the method is illustrated by applying the suggested analysis to explore visual perception issues associated with the urban remains of Late Bronze Age Akrotiri (Thera, Greece).
