CHEMICAL ANALYSIS OF COPPER ALLOY TRADE METAL FROM A POST-CONTACT HURON SITE IN ONTARIO,CANADA

Fifty-three copper-based metal fragments, recovered from the Robitaille site in southcentral Ontario, were analysed by neutron activation to establish their chemical make-up and to sort them by their trace elemental chemistries. Three different European copper samples, one brassy copper and 48 brass samples with five different chemistries were found. As few as eight trading actions may account for all of the recovered European metal fragments.     

UNRETOUCHED BLADES IN THE LATE MESOLITHIC OF SOUTH SCANDINAVIA. A FUNCTIONAL STUDY

Summary. While most microwear analyses of flint artefacts have involved formal retouched tools, this paper concentrates on unretouched blades from 4 South Scandinavian Mesolithic sites, seeking to establish how frequently and on what materials such pieces were used and whether they were selected for identifiable morphological reasons. The results are based on a study of 496 specimens, from various archaeological contexts. The materials processed ranged from soft to medium hard and most blades were used once only, as disposable tools. Their role relates more to 'manufacturing'than 'subsistence'activities. Blades seem to have been selected mainly according to their edge angles, with specific tasks in mind (a situation for which ethnographic parallels can be quoted), and they were evidently deliberately struck with a view to use rather than being chosen from random débitage. Various aspects of these conclusions are discussed.     

LÖWITH,LÖWITH'S HEIDEGGER,AND THE UNITY OF HISTORY

This article is about the problem of the unity of history as seen through the writings of Karl Löwith. By “unity of history” I understand the notion that all history constitutes one and only one range of kinds of objects and/or one field of knowledge. The article argues that the problem of the unity of history—though often neglected as a matter of mere argumentative infrastructure—is central to a number of wider problems, most prominently the possibility of a plural understanding of historicity and the possibility of ultimately avoiding a unified historical teleology. The article revisits Löwith's writings and proposes a variety of novel interpretations with the aim of evincing the centrality, and of exploring diverse aspects, of the problematic of the unity of history. This problematic is shown to have informed Löwith's work on the secularization thesis as well as his debate with Hans Blumenberg. The foundations of Löwith's discussion of the problem are pursued across his ambivalent critique and appropriation of Heidegger's model of an ontology of historicity as marked by inevitable internal conflict and thus disunity. The paper reconstructs the manner in which, after the Second World War, Löwith's philosophy of history sought to salvage basic traits of the Heideggerian model when it tried to establish the possibility of plural historicity from a notion of the natural cosmos. It is demonstrated that the motives for this salvage operation ultimately extended beyond the problem of Löwith's reception of Heidegger and concerned the possibility of continuing any debate on the philosophy of history.     

ANALYSIS OF BONE FROM THE BRONZE AGE SITE BOVENKARSPEL-HET VALKJE,THE NETHERLANDS: A PRELIMINARY REPORT

Bones from a Bronze Age settlement in a low-lying area in The Netherlands were analysed for their content of strontium and certain other elements. Low strontium concentrations in the human bones indicate that part of the diet consisted of animal products. Milk and dairy products were probably also incorporated in the diet. This would have had a marked effect on the Sr/Ca ratio of the total diet and on the strontium content of human bones. Anomalous mean strontium concentrations for the animal species are tentatively explained in relation to the specific environment of the settlement. Different pasturing practices for cattle and sheep/goat respectively are possibly reflected by the strontium content of their bones.     

Bersu's Goldberg IV: A Petty Chief's Establishment of the 6th–5th Centuries B.C.

Goldberg bei Nordlingen, located in southern Germany, was excavated earlier this century by Gerhard Bersu. The results of his work were never fully published. This paper concentrates on his excavation of the Hallstatt D settlement known as Goldberg Phase IV. An appraisal of the available evidence shows that Phase IV can be divided into two distinct Sub-Phases, and continuity of occupation is demonstrated. The fortification of Phase IVB indicates a community under threat, and an increase in social differentiation is implied by the appearance of a palisaded enclosure to house the chief and by differences in the structure and functionality of the settlement's buildings.     

A Fractal Approach to Identifying Urban Boundaries. 城市边界识别的分形方法

Fractal geometry can be used for determining the morphological boundaries of metropolitan areas. A two‐step method is proposed here: (1) Minkowski's dilation is applied to detect any multiscale spatial discontinuity and (2) a distance threshold is located on the dilation curve corresponding to a major change in its behavior. We therefore measure the maximum curvature of the dilation curve. The method is tested on theoretical urban patterns and on several European cities to identify their morphological boundaries and to track boundary changes over space and time. Results obtained show that cities characterized by comparable global densities may exhibit different distance thresholds. The less the distances separating buildings differ between an urban agglomeration and its surrounding built landscape, the greater the distance threshold. The fewer the buildings that are connected across scales, the greater the distance threshold.     

TECHNOLOGY AND PROVENANCE OF A COLLECTION OF ISLAMIC COPPER‐BASED OBJECTS AS FOUND BY CHEMICAL AND LEAD ISOTOPE ANALYSIS*

Chemical and lead isotope analyses were utilized to determine the composition, technology and origin of a collection of Islamic copper‐based objects found in Jordan. The atomic absorption spectrometry results show that the objects were made of different types of copper‐base alloys that contain various amounts of zinc, tin and lead. The use of brass, highly leaded brass and quaternary alloys of Cu‐Zn‐Sn‐Pb in the manufacture of everyday, household objects strongly points to Islamic traditions. The lead isotope compositions of the objects match very well that of the copper ore mined from the Dolomite‐Limestone‐Shale unit of the Arabah copper mines.
