青铜器与青铜时代

青铜是指红铜（纯铜）与锡或铅等元素的合金,因表面色泽黄中泛白,略显青色而得名。青铜的熔点比红铜低,而硬度却比红铜高,所以具有较强的可塑性与较高的耐用性,适合于铸造各种器具。     

Large scale smelting of speiss and arsenical copper at Early Bronze Age Arisman,Iran

We report analyses of different slag types found at the Early Bronze Age site of Arisman in North-West Iran. Here, an estimated 20 tons of slag provide evidence of sustained and large-scale production of metal, using both furnaces and crucibles. The results show that both speiss, an iron-arsenic alloy, and arsenical copper were produced, apparently side-by-side at the same site but using different ores and processes. We offer a tentative outline of the metallurgical processes involved in the production of these arsenic alloys and an explanation why speiss needed to be produced from arsenopyrite in a separate step, instead of using the mineral in its native form as a source for arsenic. We suggest that the speiss was then added either to secondary copper ore or to separately smelted copper metal, in order finally to produce arsenical copper in a regular and well-controlled process.     

Sheep wool in Bronze Age and Iron Age Europe

This study presents the results of a series of wool measurements from Bronze Age and Iron Age skins and textiles from Hallstatt, and Bronze Age textiles from Scandinavia and the Balkans. A new method of classification that was set up and applied on mostly mineralised Iron Age material has now been applied to a large body of non-mineralised material from the Bronze and Iron Ages. Three types of microscopes were used and their advantages and disadvantages assessed. The results of the investigation cast new light on sheep breeding and fibre processing in prehistoric Europe, and suggest that different sheep breeds existed in Bronze Age Europe.     

Chemical and mineralogical examination of metallurgical ceramics from a Late Bronze Age copper smelting site in Cyprus

For metallurgical processes in antiquity functional materials were required, which were sufficiently heat resistant. Commonly, ceramics were used for the production of furnaces, tuyères and crucibles. Because normal pottery usually could not withstand the extreme temperatures, which were needed for metallurgical operations, the ceramic production process had to be modified. An analytical case study will be presented on refractory ceramics from the Late Bronze Age copper smelting site Politiko-Phorades (Cyprus). Cyprus had a major role in copper production, starting from this period, and the selected site is the earliest primary smelting site discovered in Cyprus until now. Furnace and tuyère fragments were analysed chemically and mineralogically, in order to investigate ancient ceramic technology in view of heat resistance.     

Stone circles and the structure of Bronze Age society

Analyses of modern human societies have consistently demonstrated the presence of recurrent grouping levels forming a nested, hierarchical structure. That this structure exists in both hunter-gatherer and western industrialized societies suggests that it may be a fundamental organizing principle of considerable antiquity. Stone circles are perceived as being foci of aggregation for prehistoric groups and thus provide a proxy for the sizes of those aggregations. Combining an empirical analysis of a sample of 140 stone circles with a Monte Carlo simulation model that derives expectations for a continuous size distribution based on the nested hierarchy concept, the current paper suggests that similar organizing principles were already in place during the Bronze Age. Furthermore, it is suggested that findings traditionally attributed to the operation of the ‘rank-size rule’ may in fact reflect the basic underlying structure of human society.     

A Bronze Age Quarry in Eastern Crete

Abstract

The sandstone quarry at Mochlos is one of four major quarries in eastern Crete that were worked during the New Palace Period of Minoan civilization (ca. 1700–1450 B.C.) to produce large ashlar blocks for nearby Minoan sites. At that time sandstone, or ammoudha, as it is known locally, was especially valued as a building material, partly because of its distinctive color and texture, but mainly because of the ease with which it could be cut, and the stone was used extensively for exterior façades, for walls around interior courts, and for other architectural features of the more important buildings on these sites. This article describes the quarry at Mochlos in some detail, including the quarrying techniques employed, and argues that the destination of the stone from the Mochlos quarry was the Minoan palace at Gournia. The article ends with a comparison of the four ammoudha quarries in eastern Crete.

Evidence of Social Stratification in Bronze Age Denmark

Abstract

The Late Bronze Age hoards (12th–6th centuries B.C.) from Denmark are examined as evidence of the existence of social ranking in that prehistoric society. The hoards contain bronze weapons and ornaments which seem to function as sumptuary goods and appear to be ranked according to regular rules. The hoards also represent economic wealth and include objects of ritual importance. This intersection, in single finds, of material reflections of the political, religious, and economic systems in the society, along with the inferred existence of social ranking, suggests the presence of a prehistoric chiefdom in Denmark in the Late Bronze Age.     

Middle Bronze Age Ramparts: Functional and Symbolic Structures

Abstract

The Middle Bronze Age is a period of urban rebirth, with one of its hallmarks being massive earthworks surrounding cities. These structures have been studied extensively, with traditional interpretations of their function revolving around defensive aspects. However several scholars have called into question the validity of these interpretations, offering alternative explanations revolving around more “social” reasons. The present paper suggests that while the structures were constructed for protecting the city and its inhabitants, this only strengthens its “social” symbolism. Of major importance to its symbolism is the effect the ramparts had on the landscape, altering it permanently, and giving an impression of controlling the landscape.

Natural preservation mechanisms at play in a Bronze Age wooden shovel found in the copper mines of Alderley Edge

A wooden shovel, dating from the Early Bronze Age, has survived in a remarkable state of preservation in the copper mines of Alderley Edge, Cheshire UK. Other historic timbers recovered from the mines, whilst still intact, have fared less well. An X-ray investigation into the distribution of minerals through the shovel using portable X-ray Fluorescence (PXRF) along with the use of synchrotron-based X-ray Absorption Spectroscopy (XAS) measurements of the copper and arsenic chemical speciations has provided clues to the methods by which metals from the mining environment have entered the wood of the shovel and ensured its survival. The distribution and nature of the minerals so determined suggest that the copper and arsenic, along with a significant lead content, entered the shovel during its original use in working mineral-rich deposits, rather than through the burial environment. The insights gained are expected to be applicable to other wooden artefacts recovered from ancient copper mines in other places.     

Bronze and Iron Age Amber Artifacts in Croatia and Bosnia-Hercegovina

Abstract

The question as to whether or not Yugoslavia played a role in the Bronze Age amber trade to Greece has traditionally been answered negatively because of the scarcity of amber finds in that country. Amber finds that have come to light as a result of more intensive exploration after World War II have been thought to be of local origin by some Yugoslav scholars. Spectroscopic analysis of 35 archaeological amber artifacts from the Yugoslav provinces of Croatia and Bosnia-Hercegovina of the Bronze and Iron Age shows 31 of them to be of imported Baltic amber. The finds are discussed in their archaeological and geographic contexts as a first step towards re-assessing the place of the Eastern Adriatic area in the southward movement of amber.     

The Origins of the Bronze Age of Southeast Asia

White and Hamilton (J World Prehist 22: 357–97, 2009) have proposed a model for the origin of the Southeast Asian Bronze Age founded on seven AMS radiocarbon determinations from the Northeast Thai site of Ban Chiang, which would date the initial Bronze Age there to about 2000 BC. Since this date is too early for the derivation of a bronze industry from the documented exchange that linked Southeast Asia with Chinese states during the 2nd millennium BC, they have identified the Seima-Turbino 3rd millennium BC forest-steppe technology of the area between the Urals and the Altai as the source of the Southeast Asian Bronze Age. We challenge this model by presenting a new chronological framework for Ban Chiang, which supports our model that the knowledge of bronze metallurgy reached Southeast Asia only in the late 2nd millennium BC, through contact with the states of the Yellow and Yangtze valleys.
