Carl Heron Gørill Nilsen Ben Stern Oliver Craig Camilla Nordby 《Journal of archaeological science》2010
Gas chromatography–mass spectrometry (GC–MS) and bulk carbon isotope determinations have been performed on samples (‘cemented organic residues’, charcoal, sediment and fire-cracked rock) excavated from 12 slab-lined pits from various locations in Arctic Norway to test the premise that these archaeological features were used for the extraction of oil from the blubber of marine mammals, such as seal, whale and walrus. A wide range of lipid compound classes were detected especially in the cemented organic residues and in the charcoal samples. The presence of long-chain unsaturated and isoprenoid fatty acids together with oxidation and thermal alteration products of unsaturated acids such as dicarboxylic acids, dihydroxyfatty acids and ω-(o-alkylphenyl)alkanoic acids suggests that these features were used for marine oil extraction at elevated temperatures. Notably the location of the hydroxyl groups in the dihydroxyfatty acids provides a record of the positional isomer of the precursor fatty acid and allows confirmation that 11-docosenoic (cetoleic) acid, the most abundant C22:1 isomer in marine oil, was a major component of the original lipid. Further information was provided by the presence of long-chain fatty acyl moieties in surviving triacylglycerols and the presence of cholesterol. A fungal metabolite, mycose (trehalose), was found in all samples apart from a fire-cracked rock and points to microbiological activity in the pits. Bulk isotope analysis conducted on the ‘cemented organic residues’ is consistent with modern reference samples of blubber and oil from seal and whale. These data provide clear analytical evidence of the function of slab-lined pits in the archaeological record and suggest widespread exploitation of marine mammals for producing oil for heating, lighting and myriad other uses in the past. 相似文献

Textural, mineralogical, and X-Ray fluorescence (XRF) analyses are used as a cost effective method to distinguish for the first time ancient Egyptian and Nubian-style ceramics found in Nubia. Textural and mineralogical data suggest that Nubian-style sherds are mixtures of sand, silt, and clay sediment that is generally finer grained and poorer in quartz than is the sediment mixture used to produce Egyptian-style pottery. Chemical data also establish a significant difference in the amount of chemical variation found within each style population, but nonetheless supports a considerable overlap in the possible provenance of both styles. Observations and data obtained during this study indicate that standardized, Egyptian-style manufacturing was introduced into Nubia under colonialism, without substantially altering the diversity of native methods of production. 相似文献

Carl I. Hammer 《Early Medieval Europe》1997,6(1):47-76
Based upon an examination of the Bavarian law code and detailed analysis of thirty eighth- and ninth-century deeds from Bavarian cartularies, this article argues that land sales were common in early medieval Bavaria and generally followed codified procedures, derived in part at least, from late-Roman vulgar law. The essential element in the sale was the payment of the purchase price ( pretium ) which established its validity. This purchase price, even when expressed in monetary forms, was seldom executed in specie and was determined by customary social as well as strictly economic considerations. The Church probably was the primary purchaser of land to consolidate properties obtained by gift, and lay men and women sold land to meet public obligations, to obtain necessary stock and to satisfy personal wants. 相似文献

The author discusses aspects of how time appears and is used by the individual and by society. In focus is what the author calls the ideological time scale as it appears in Western society. The concept of the ideological time scale implies systems of strong, ideological signals transferred through time in the human mind from one generation to another. One such signal is the age-old concept of the hero and the symbolism projected around this concept. The paper ends with an admonition to scholars to be aware of and study the kinds of messages transferred through time by this signal system. These messages carry important information about the ways in which society directs itself in the time continuum. 相似文献
