High dynamic range imaging for archaeological recording

This paper notes the adoption of digital photography as a primary recording means within archaeology, and reviews some issues and problems that this presents. Particular attention is given to the problems of recording high-contrast scenes in archaeology and High Dynamic Range imaging using multiple exposures is suggested as a means of providing an archive of high-contrast scenes that can later be tone-mapped to provide a variety of visualisations. Exposure fusion is also considered, although it is noted that this has some disadvantages. Three case studies are then presented (1) a very high contrast photograph taken from within a rock-cut tomb at Cala Morell, Menorca (2) an archaeological test pitting exercise requiring rapid acquisition of photographic records in challenging circumstances and (3) legacy material consisting of three differently exposed colour positive (slide) photographs of the same scene. In each case, HDR methods are shown to significantly aid the generation of a high quality illustrative record photograph, and it is concluded that HDR imaging could serve an effective role in archaeological photographic recording, although there remain problems of archiving and distributing HDR radiance map data

Palimpsests of Immaterial Assemblages Taken out of Context: Tracing Pompeians from the Void into the Digital

This paper explores some ontological aspects of archaeological voids and enclosures together with their translations and substitutions, and considers the nature of spaces within material archaeological deposits and artefacts. The dematerialized and rematerialized bodies of the victims of Vesuvius in CE 79 are reappraised as a case study. By problematizing the voids we are able to think critically about the ontological status of the victims’ persistent traces and residues. Specifically, using Gavin Lucas’ grid of forces models, we explore how these traces and residues have been transformed into different kinds of objects, including, most recently, rematerializations in the digital, through their ongoing intra-actions within the domains of archaeology, museology, and additive manufacturing. Through this analysis the ambivalent nature of these traces and residues becomes more sensibl

An Exploratory Spatial Analysis of the Churches in the Southern Mani Peninsula, Greece

The Mani Peninsula is home to hundreds of Orthodox Christian churches that were built within the last millennium. As in other parts of the Eastern Mediterranean countryside, the topological relationship between churches and settlements is a critical factor in understanding the significance of the sacred landscape. Many churches are situated in the central part of a village or on its very edge, but others – what are referred to as “outlying churches” or exokklisia – are built at great distances away. In this paper, we make the first attempt to assess the spatial relationship between the spaces where people worshipped (the churches) and the spaces where they lived (the settlements) at a regional scale, focused specifically on the Middle Byzantine period and later (mid-9th century CE to the present day). Comparing these patterns across the Byzantine, Ottoman, and Modern periods allows us to frame Mani’s sacred infrastructure within a changing, diachronic perspective. The results point to a change in the topological relationship between church and settlement that is best described as the “nucleation of the sacred landscape.

The byre's tale : farming nutrient-poor cover sands at the edge of the Roman Empire

ABSTRACT Prior to the construction of a highABSTRACT-speed railway track (TGV) between Antwerp (Belgium) and the Dutch border, archaeological and geoarchaeological research was conducted at several archaeological sites. All are situated in the northern Campine, a region characterised by quartz-rich, nutrient-poor cover sands. On the site of Brecht-Zoegweg, two well preserved deepened byres (‘potstallen’) were uncovered in Roman stable-houses. Stables with sunken floors are commonly recorded on Roman-period farms in the sandy part of northern Belgium. Following medieval to sub-recent parallels in the area, they are considered to be features serving agricultural fertilising purposes through the intentional accumulation of dung and the creation of manure by mixing with added organic matter (sods or ‘plaggen’). This archaeopedological research investigates several questions concerning the origin and the infill process of these remarkable features. Field observations, analytical and micromorphological data point to a gradual succession of events leading to a byre with a sunken floor, rather than an intentional digging out of the floor concomitant with the house construction and a post-occupational filling or levelling. It is furthermore suggested that plaggen fertilisation could indeed have been applied, at least in some of the phases of the byre use.This article is part of a book edited at the occasion of the Geoarchaeological meeting of Bruges: Soils as records of Past and Present: the geoarchaeological approach.

Assessment of plastics in the National Trust: a case study at Mr Straw's House

The National Trust is a charity that cares for over 300 publically accessible historic buildings and their contents across England, Wales and Northern Ireland. There have been few previous studies on preservation of plastics within National Trust collections, which form a significant part of the more modern collections of objects. This paper describes the design of an assessment system which was successfully trialled at Mr Straws House, a National Trust property in Worksop, UK. This system can now be used for future plastic surveys at other National Trust properties. In addition, the survey gave valuable information about the state of the collection, demonstrating that the plastics that are deteriorating are those that are known to be vulnerable, namely cellulose nitrate/acetate, PVC and rubber. Verifying this knowledge of the most vulnerable plastics enables us to recommend to properties across National Trust that these types should be seen as a priority for correct storage and in-depth recording

Geographical information retrieval with ontologies of place

Geographical context is required of many information retrieval tasks in which the target of the search may be documents, images or records which are referenced to geographical space only by means of place names. Often there may be an imprecise match between the query name and the names associated with candidate sources of information. There is a need therefore for geographical information retrieval facilities that can rank the relevance of candidate information with respect to geographical closeness of place as well as semantic closeness with respect to the information of interest. Here we present an ontology of place that combines limited coordinate data with semantic and qualitative spatial relationships between places. This parsimonious model of geographical place supports maintenance of knowledge of place names that relate to extensive regions of the Earth at multiple levels of granularity. The ontology has been implemented with a semantic modelling system linking non-spatial conceptual hierarchies with the place ontology. An hierarchical spatial distance measure is combined with Euclidean distance between place centroids to create a hybrid spatial distance measure. This is integrated with thematic distance, based on classification semantics, to create an integrated semantic closeness measure that can be used for a relevance ranking of retrieved objects

Transit, Transition Excavating J641 VUJ.

In July 2006 archaeologists from the University of Bristol and Atkins Heritage embarked on a contemporary archaeology project with a difference. We ‘excavated’ an old (1991) Ford Transit van, used by archaeologists and later by works and maintenance teams at the Ironbridge Museum. The object: to see what can be learnt from a very particular, common and characteristic type of contemporary place; to establish what archaeologists and archaeology can contribute to understanding the way society, and specifically we as archaeologists, use and inhabit these places; and to challenge and critique archaeologies of the contemporary past. In this report we describe our excavation and situate it within a wider debate about research practice in contemporary archaeology
