Animal dung from arid environments and archaeobotanical methodologies for its analysis: An example from animal burials of the Predynastic elite cemetery HK6 at Hierakonpolis,Egypt

Abstract

Paraffin flotation has been used extensively in archaeoentomology and paleoentomology in the last four decades but not tested systematically. Its efficiency is here assessed. Eighty-five per cent of the identifiable coleopteran remains were recovered regardless of any variables. Some explanations of the method's variable efficiency given in published literature were tested, namely the experience of the technician, the nature of the residue, and the taxon and body part. Difference in recovery rates between four categories of workers proved significant. Residue type influences the efficiency of the method but the type of sclerite was of little importance in the process. Overall, however, paraffin flotation was shown to be sufficiently efficient and its continued use is recommended.     

Hydrological monitoring of an alluviated landscape in the lower Great Ouse valley at Over,Cambridgeshire: the quarry restoration phase

Abstract

This paper sets out the results of the last phase of the hydrological monitoring programme conducted at the Hanson Over quarry in Cambridgeshire, during the first full year (March 2004 to March 2005) in which the area of the first phase of gravel extraction was reinstated as reed beds under the management of the Royal Society for the Protection of Birds. It follows on from the studies of the pre-extraction and extraction phases, both published previously in Environmental Archaeology (French et al. 1999; French 2004). It is reassuring to report that the groundwater table in the formerly quarried area and the landscape immediately upstream and downstream has ostensibly been restored to pre-extraction levels, along with a return to previous pH, conductivity, redox and dissolved oxygen values in the groundwater system. Significantly, the continuing gradual fall in groundwater levels observed beyond 500 m from the quarry face for a distance of at least 1·5 km was seen to be arrested, although these had not quite recovered to pre-extraction levels downstream to the northeast. In addition, the soil moisture within the alluvial overburden and the buried palaeosol has also almost returned to pre-extraction levels. This indicates that the clay bunding of the formerly quarried areas acts as an effective barrier against further water abstraction, both inside and outside the sealed area, and allows the natural aquifer to begin to return to its previous levels of influence.

The study dramatically indicates that both the mineral operator, drainage authority and archaeological curator need to collaborate from the outset of any quarrying operation to ensure the continuing maintenance of the groundwater and soil moisture system regardless of how well the combined gravel and water abstraction processes are conducted, and how successful the post-quarry conservation is. As every site's landscape dynamics contribute to its individual hydrological setting, each case is different and requires tailored monitoring programmes to protect the archaeological and palaeo-environmental record from the adverse effects of water abstraction associated with development schemes.     

Mortimer Wheeler's Theatre of the Past

Abstract

This paper examines the nature of Mortimer Wheeler's work as a public archaeologist, and in particular his efforts to display the archaeological process to interested members of the public. By focusing on the excavations at Maiden Castle, Dorset, from 1934 to 1937 we compare Wheeler's stated philosophy of public archaeology with his practice in the field. At Maiden Castle the theatre of excavation was the centrepiece of a carefully marketed archaeological experience including tours, souvenirs, and a well-developed media strategy. By applying the commodity model of public archaeology as an analytical framework we highlight the sophistication and success of Wheeler's 'theatre of the past'. This analysis lays a foundation for further critical historical studies of both the public understanding of the past, and of Wheeler's life and works.     

Electron paramagnetic resonance of mosaic glasses from the Mediterranean area*

Ancient mosaic glass tesserae sampled from archaeological sites located in the Mediterranean area have been analysed by Inductively Coupled Plasma‐Optical Emission Spectroscopy (ICP‐OES). The aim of the research was to understand the role played by 3d transition metals in the optical properties of such samples. In order to better identify the specific effect of the main chromophorous element, modern samples have been prepared in the laboratory by adding to a colourless base frit controlled concentrations of colouring oxides. Samples with compositional and optical properties similar to the ancient ones have been obtained. For all these modern samples, as well as for all the ancient ones, electron paramagnetic resonance (EPR) measurements have been performed. The features of the EPR spectra could be successfully associated with the presence and abundance of the paramagnetic colouring ions (namely iron, manganese and copper) and to their oxidation states. This could be a basic step towards understanding the provenance and chronological attribution of mosaic glass tesserae.     

CHEMICAL AND MINERALOGICAL APPROACHES TO THE ORGANIZATION OF LATE BRONZE AGE NUZI WARE PRODUCTION

In order to investigate the nature and organization of high‐status ceramic production in the Late Bronze Age, samples of Nuzi Ware from four different sites were analysed using scanning electron microscopy (SEM–EDS) and inductively coupled plasma atomic emission spectroscopy (ICP–AES). Chemical and mineralogical evidence suggests that Nuzi Ware was produced in at least two distinct regions, one probably in the Adhaim Basin in northern Iraq and another possibly in the Orontes catchment in southeastern Turkey. The existence of individual production units probably developed in response to the local elites' desire to imitate the tastes of the Mitanni aristocracy, resulting in a mapping of political relationships on to material culture.     

The Use and Deployment of Modern Wood Samples as a Proxy Indicator for Biogeochemical Processes on Archaeological Sites Preserved in situ in a Variety of Environments of Differing Saturation Level

Abstract

In situ preservation of archaeological sites is becoming an ever increasing trend as a means of preserving our cultural heritage. In connection with this the environmental conditions, such as water level, dissolved oxygen, temperature, pH and water chemistry, of a site are often monitored. It is generally agreed that a waterlogged and anoxic environment is essential for optimal preservation conditions but the set-up and maintenance of an environmental monitoring programme can be costly.

This paper discusses the design and use of a system whereby modern samples of wood can, with a minimal disturbance of the soil, easily be deployed and retrieved from archaeological sites. The system was deployed in an unsaturated environment, an environment with fluctuating water levels and a fully saturated peat bog. The samples were assessed after two years using microscopic, physical and molecular biological methods, and the types of wood-degrading organisms seen were compared with the results of environmental measurements. Modern wood samples were used, as the microbial ecology of wood-degrading organisms in these different types of environments is relatively well documented. Preliminary conclusions show that the deterioration processes of modern wood samples in these environments act as a good proxy indicator of the environmental conditions and biogeochemical processes ongoing at a site.     

DISTINCT,LATE BRONZE AGE (c. 1650 bc) WALL‐PAINTINGS FROM AKROTIRI,THERA, COMPRISING ADVANCED GEOMETRICAL PATTERNS*

This paper studies a set of wall‐paintings of the Late Bronze Age (c. 1650 bc ) initially decorating the internal walls of the third floor of the edifice called ‘Xeste 3’, excavated at Akrotiri, Thera, whose restoration is now in progress. It deals with the methods used for the drawing of the geometrical figures appearing in these wall‐paintings. It is demonstrated that most of the depicted configurations correspond with accuracy to geometrical prototypes such as linear spirals and canonical polygons. It is pointed out that the steady lines of the figures, their remarkable repeatability, the precision of the geometrical shapes and their even distribution in the wall‐paintings indicate a very distinctive use of the ‘Xeste 3’ third floor, which is now investigated.     

SOUTHERN ASIA'S OLDEST INCENDIARY MISSILE?*

A small burnt ball was recovered in 1995 from the basal fills of a ditch surrounding the Bala Hisar, or High Fort, of Charsadda, Pakistan. Associated by Sir Mortimer Wheeler with the siege of the ancient site by Alexander the Great in 327 bce , the ditch forms part of the city's defensive circuit. Using geochemical and microscopic techniques (X‐ray diffraction, micro‐FTIR, SEM and GC–MS) the ball is identified as an artificial composite of mineral (mostly barite) and flammable resinous organic matter originating from conifers from the Podocarpaceae, Araucariaceae and Cupressaceae. The physical and chemical nature of the find suggests that the ball was ignited in a fire, although whether this was a deliberate or accidental occurrence is impossible to establish. The analytical data, combined with the archaeological context of the find, leads us to evaluate whether the find represents southern Asia's earliest incendiary missile.

ARCHAEOMETRICAL INVESTIGATION OF SICILIAN EARLY BYZANTINE GLASS: CHEMICAL AND SPECTROSCOPIC DATA*

A series of early Byzantine glasses, recovered in Ganzirri (Sicily, Italy), was analysed for major, minor and trace elements. All the analysed fragments were found to be natron-based silica–lime glass. Concerning minor and trace elements, the samples can be divided into two groups: glass with high Fe, Ti and Mn contents ( HIMT glass) and glass with low levels of Fe, Ti and Mn. These results, strictly in agreement with literature data for glass of the Mediterranean region, can be interpreted as a consequence of the wide trade network established in this region and of the intense circulation of raw glass and artefacts from different Mediterranean areas. X-ray absorption spectroscopy studies at Fe and Mn K-edges, performed on HIMT glass, indicate that Fe is in the oxidized form while Mn is in the reduced form.
