Seventh Centuries AD (seventh + century_ad)
Selected AbstractsDefining the OE hearg: a preliminary archaeological and topographic examination of hearg place names and their hinterlandsEARLY MEDIEVAL EUROPE, Issue 4 2007Sarah Semple The OE term hearg is interpreted variously as ,pagan temple', ,hilltop sanctuary' and even ,idol'. It is a rare survival in the English place-name record. When it can be identified, the place name is commonly considered to refer to a location of pre-Christian religious activity, specifically a pagan Anglo-Saxon temple. Taking inspiration from the extensive and methodologically well-advanced studies in Scandinavia, which have successfully related place-name evidence for cultic and religious sites with the archaeology and topography of these localities, this paper adopts and uses a similar methodology to investigate the archaeological and topographic character of a selection of hearg locations. The traditional interpretations of the place name are questioned and evidence is presented that these sites are characterized by long-lived, localized cult practice spanning the late prehistoric to early historic periods, but with activity reaching a zenith in the late Iron Age to Romano-British eras, rather than the fifth to seventh centuries AD. [source] The decline of eastern Arabia in the Sasanian periodARABIAN ARCHAEOLOGY AND EPIGRAPHY, Issue 1 2007Derek Kennet This paper lists and reviews the archaeological evidence for the Sasanian period in eastern Arabia (third,seventh centuries AD). Much of the published evidence is shown to be either erroneous or highly doubtful, leaving very little evidence that is reliable. It is argued that the paucity of evidence in comparison to the Hellenistic/Parthian period indicates that this was a time of marked and continuing decline in the number and size of settlements, the number of tombs and the amount of coinage in circulation, all of which probably result from a population that was both declining in size and participating less in the types of production and consumption that leave discoverable traces in the archaeological record. This is in contrast to the historical evidence, which, although patchy, is stronger for the Sasanian period than it is for the Hellenistic/Parthian period. The argument for decline challenges some generally accepted historical views of eastern Arabia at this time, which see the region as undergoing a notable period of growth. In conclusion, some brief consideration is given to the possible causes of the decline. [source] A MULTI-ANALYTICAL APPROACH FOR THE CHARACTERIZATION OF COMMODITIES IN A CERAMIC JAR FROM ANTINOE (EGYPT),ARCHAEOMETRY, Issue 3 2009E. RIBECHINI This paper describes a multi-analytical chemical study performed on the original, almost totally conserved, content of a small ceramic jar from the Antinoe archaeological site (fifth to seventh centuries ad, Roman Egypt) and now belonging to the archaeological collection of the Istituto Papirologico ,Girolamo Vitelli' (Florence, Italy). Scanning electron microscopy with an energy-dispersive X-ray spectrometer (SEM,EDX), Fourier transformed infrared spectroscopy (FTIR) and X-ray diffraction (XRD) were all used to characterize the inorganic components of the archaeological material. The organic substances were analysed using FTIR, direct exposure mass spectrometry (DE,MS) and gas chromatography , mass spectrometry (GC,MS). The inorganic component essentially consisted of halite (NaCl). Among the NaCl crystals, lamellar elements were identified. They were chemically characterized by carbonato-apatite and showed a concentric morphology typical of the scales of small fish. The most prevalent organic constituents of the sample were monocarboxylic acids, ,,,-dicarboxylic acids, and cholesterol and its oxidation products. The organic material composition was consistent with the occurrence of lipids of animal origin. In addition, diterpenes related to pine pitch were also identified. The overall results suggest that the material recovered in the small ceramic jar found in Antinoe is a residue of fish-based pickles such as garum, muria, allex and liquamen, which were commonly used in Roman times. [source] THE COMPOSITION AND MANUFACTURE OF EARLY MEDIEVAL COLOURED WINDOW GLASS FROM SION (VALAIS, SWITZERLAND),A ROMAN GLASS-MAKING TRADITION OR INNOVATIVE CRAFTSMANSHIP?*ARCHAEOMETRY, Issue 2 2005S. WOLF Archaeological excavations between 1984 and 2001 at the early Christian cemetery church in Sion, Sous-le-Scex (Rhône Valley, Switzerland), brought to light more than 400 pieces of coloured window glass dating from the fifth or sixth centuries ad. The aims of this paper are threefold: first, to characterize the shape, colour and chemical composition of the glass; secondly, to understand whether the production of the coloured window panes followed traditional Roman glazing techniques or was of a more innovative nature; and, thirdly, to provide some indications as to the overall design of these early ornamental glass windows. Forty samples of coloured glass have been analysed by wavelength-dispersive X-ray fluorescence. The results of the chemical and the technological studies showed that most of the glass was produced using recycled glass, particularly as a colouring agent. Some of the glass was made of essentially unmodified glass of the Levantine I type. The results taken together seem to confirm that raw glass from this region was widely traded and used between the fourth and seventh centuries ad. The artisans at Sion were apparently still making use of the highly developed techniques of Roman glass production. The colour spectrum, manufacture and design of the windows, however, suggest that they represent early examples of ornamental coloured glass windows. [source] A multi-proxy study of Holocene lake development, lake settlement and vegetation history in central Ireland,JOURNAL OF QUATERNARY SCIENCE, Issue 2 2005K. A. Selby Abstract Stratigraphical investigations, geomorphological mapping, and diatom, plant macrofossil and pollen analyses were undertaken in and around two lakes in central Ireland to establish correlations between changes in lake conditions and catchment vegetation throughout the Holocene. Similar investigations of an adjacent mire reveal early Holocene changes in lake level and area. The palaeoecological data show high correlations related to variations in lake depth and area, catchment vegetation type, organic inputs and trophic status. Catchment-scale deforestation is gradual and occurs through the Bronze and the Iron Ages, and the construction of a crannog in the early Medieval period (seventh century AD) appears to be associated with a widespread increase in deforestation and mixed agriculture in the catchment. Both pollen and plant macrofossils suggest that one of the crannogs was used for crop storage in addition to domestic and any other activities. In the early to middle Holocene similarities in the proxy-data appear to be climatically driven through changing lake levels and areal extent whereas the later Holocene record is clearly dominated by anthropogenic changes within the catchment and the construction of crannogs in the lakes. The advantages of combining multi-proxy indicators of lake hydroecology with the vegetation record are illustrated. Copyright © 2005 John Wiley & Sons, Ltd. [source] Archaeomagnetic investigations of Iron Age slags in Denmark,ARCHAEOLOGICAL PROSPECTION, Issue 2 2003Niels Abrahamsen Abstract In Denmark iron production, by means of reducing bog-iron ore with charcoal, was carried out at least between the second and seventh century AD. Since the 1960s magnetic mapping of iron slag remains have been used extensively at several sites in the southwestern part of Jutland in Denmark (e.g. at Drengsted, Snorup, Krarup and Yderik). A description of some of the magnetic surveying results, ideas of magnetic modelling, and magnetic and chemical analysis of slag from some of these areas are given. The Danish Iron Age slag pits are strongly magnetic, and consequently they are quite easy to locate magnetically. The slag, however, is often magnetically non-homogeneous, and accordingly the remanent magnetic direction of the original magnetization is not uniform. Hence individual slag pits are not good recorders of the direction of Earth's magnetic field. Therefore dating of individual slag pits by means of a magnetic mastercurve, using either inversion and modelling of the magnetic field anomaly from the slag, or by using conventional palaeomagnetic techniques by orientated cores, are still difficult to make with sufficient resolution.
