Recovering social and cultural dynamics from plaster floors: chemical analyses at ancient Chunchucmil,Yucatan, Mexico

Phosphate analysis and trace metals analysis were used to determine activities that took place on plaster floors in domestic contexts at the ancient Maya site of Chunchucmil, Yucatan. Research on activities and the use of space contributes to an understanding of social relations within household groups as well as unforeseen patterns that structure refuse discard. The floors analyzed in this paper pertain to three structures in two neighboring houselots dating to the Early Classic (300–600 A.D.) period. Data from the chemical analyses were utilized in conjunction with associated architectural features and artifacts found on the floors. These three lines of information were interpreted with the help of models developed from ethnographic and ethnoarchaeological research. The results demonstrated functional differentiation of rooms within elaborate residences and suggested that front rooms were used to host visitors. The results also suggested that different types of debris were managed differently. Finally, chemical analyses suggest that non-elite Maya occasionally enacted rituals often restricted to elites.     

Identifying wine and oil production: analysis of residues from Roman and Late Antique plastered vats

The production of oil and wine was an important aspect of the ancient Mediterranean economy. Among the material remains related to the production of these substances, installations used for their production provide evidence that is still unexploited. Although archaeological studies have been carried out on these installations, problems can arise in the identification of their function, as wine and oil production structures can be similar and the archaeological traces insufficient to establish which substance was produced.     

Understanding evolution in the Antwerp chemical cluster: the role of regional development strategies

Research on regional economic development increasingly embraces more nuanced perspectives on the evolution of clusters, industries and agglomerations. The extent to which the emergence and decline of clusters can be directed with intentional regional development strategies is, however, a major point of discussion. The article links the cluster life cycle concept to regional development strategies in order to examine the trajectory of Europe’s largest chemical complex in and around the Port of Antwerp (Belgium). This chemical cluster has matured and currently is in a state of stability. Although the cluster did not experience growth over the last decades in terms of new entrants, it did transform internally and maintained its importance as a production centre. Thus, whereas lock-in mechanisms hampered growth, they also prevented the cluster from going into a state of decline. We argue that while regional development strategies stimulated new emerging clusters in the Flemish region, vested interests in the port and associated lock-in mechanisms have resisted such developments in Antwerp. New growth trajectories based on the chemical cluster were therefore difficult to recreate in the Antwerp region.     

Magendie and the chemists: the earliest chemical analyses of the cerebrospinal fluid

Having described the spinal fluid, Fran?ois Magendie (1783-1855) called upon a number of chemists in Paris to analyze the material, in the effort to decide if it was a special secretion of the nervous system or simply a filtrate of the blood. J.L. Lassaigne (1800-1859) and J.P. Couerbe (1805-1867) responded. Their results, and those of some earlier investigators, are described. In the ensuing years of the nineteenth century, other investigators similarly conducted analyses of spinal fluid, but these were usually of single constituents in poorly defined diagnostic conditions. In 1909-1912, William Mestrezat (1883-1928) took advantage of the recently introduced technique of lumbar puncture, which by now had become hospital routine, and introduced the modern era of systematic analysis of many components of the spinal fluid, correlated with specific disease states.

Ancient technology and computer aided design: olive oil production in southern Spain

Abstract

Until the twentieth century, the two most widely used technologies for extracting oil from olives were the tower press and the beam press. Although many examples still exist, this paper is the first to discuss either press from the point of view of engineering. Working from sketches, photographs and measurements obtained from exhibits in the Museo de la Cultura del Aceite (Museum of Oil History) in Hacienda 'La Laguna', Jaén, Andalucia, Spain, the presses have been modelled using computer aided design techniques. Computer animation has also been employed to establish how the presses worked.     

Testing the provenance of Patayan pottery at Las Colinas: chemical and petrographic analyses of phyllite-temper fragments

Mobile Patayan foragers of the interior desert of southwestern Arizona were makers of Lower Colorado Buff Ware ceramics. These containers were sometimes traded to Hohokam irrigation agriculturalists at the western margin of the Hohokam territory. By A.D. 1100, the distribution of Patayan Buff Wares shifted to the east, penetrating the Hohokam heartland. Some theorists have suggested the ceramic distribution implies a migration of Patayan people, who joined agricultural communities in the Hohokam core area. One way to assess this idea is to identify the production of Patayan material culture within the Hohokam territory. We test for the local manufacture of Lower Colorado Buff Ware at the Hohokam village of Las Colinas, where Patayan pottery was found in abundance, and a Patayan enclave has been inferred. Using petrographic analysis and SEM-EDS assays of the phyllite temper fragments in the Patayan wares, we conclude that the Patayan pottery was made elsewhere and was not fabricated with local materials at Las Colinas.     

Societal repercussions of the rise of large-scale traditional iron production: a West African example

Numerous scholars have outlined what they believed to be the consequences of the advent of iron technology in sub-Saharan Africa: increased food production using more efficient bush clearing tools; increased population densities; larger and more stable communities; increased trade, specialization and social differentiation; and the embryonic rise of modern politics. (Davidson 1974.) However, little has been demonstrated in the field.A regional study of the Bassar iron industry of northern Togo has shown that the rise of large-scale iron production may lead to higher population densities, larger and more stable communities, a more aggregated settlement pattern in the ore zone, and increased craft specialization and trade. However, it does not necessarily result in a significant increase in the degree of political centralization. The Bassar data also suggest that even the appearance of relatively small scale iron production may generate similar trends, albeit at more modest levels.

Résumé De nombreux auteurs ont décrit ce qu'ils proposent d'avoir été les conséquences de l'adoption de la technologie de fer dans l'Afrique au sud du Sahara: augmentation de la production de nourriture à l'aide des outils plus efficaces pour débroussailler le paysage; augmentation des densités de population; communautés plus grandes et plus stables; croissance de la commerce, de la specialisation artisanale et de la differentiation sociale; et naissance embryonique de la politique moderne (Davidson 1974). Cependant il n 'y a que très peu de ce schéma qui a été validé par les recherches sur le terrain.Une étude régionale de l'industrie du fer des Bassar du nord de Togo a montré que l'essor de la production de fer à grande échelle peut aboutir à des densités de population plus hauts, des communautés plus grands et plus stables, une répartition de l'habitat plus agrégée dans la zone des minerais de fer, et l'augmentation de la specialisation artisanale et du commerce. Cependant il n'aboutit pas obligatoirement à une centralisation importante au niveau politique. Les résultats fournis par cette étude des Bassar nous amènt à proposer aussi que même l'apparition de la production modeste de fer peut donner naissance à des développements comparables, mais d'un ampleur plus restreint.

     

Deciphering the inorganic chemical record of ancient human activity using ICP-MS: a reconnaissance study of late Classic soil floors at Cancuén,Guatemala

Inorganic chemical analysis of soil floors using inductively coupled plasma-mass spectrometry (ICP-MS) was undertaken to provide information on the nature and location of past human activity in the ancient Maya city of Cancuén, Guatemala. The use of ICP-MS to detect trace and ultra-trace elemental enrichment of two excavated soil floors from the late Classic period is the first study of its kind in Mesoamerican archaeology. Geochemical background of the site was established by the analysis of palaeosols and nearby undisturbed ‘off-site’ soil profiles. Robust statistical methods used in the study clearly distinguished the level of anthropogenic enrichment across the former floors. Many elements measured showed only minor departures (10–20%) from the site's background soil chemistry. The greatest levels of elemental enrichment were detected in the rare earth elements, mercury, and gold. The latter is of particular interest considering the consensus that gold was absent from the world of the Classic-period Maya. Comparisons of the spatial pattern of mercury enrichment with lithic and archaeological data show strong linkages to past industrial and ritual activities. Elevated rare earth element concentrations were recorded broadly across both soil floors and are considered to be related to concentrated human occupation in antiquity.     

A comparison of chemical and petrographic analyses of Neolithic pottery from South-eastern Europe

This paper deals with the importance of chemical analyses in characterising prehistoric pottery fabrics. Two three-year projects focussed on the minero-petrographic and SEM/EDS analyses of the oldest pottery from south-east Europe (ca. 6000 cal BC). Whereas in the Impressed Ware culture of the Adriatic region, optical microscopy was sufficient to identify provenance, the more uniform geological background of the central Balkans required chemical analyses to be able to differentiate between different raw materials. Multiple bulk analyses of each sherd were obtained to gauge the variability in composition within each vessel. The limiting factor in determining provenance in this area appears to be the similarity of clay sources, not the inhomogeneity of the coarse pottery. This is shown here using results from four of the sites, including three where petrographic analyses could not establish provenance.     

Ceramic production,consumption and exchange in the Banda area,Ghana: Insights from compositional analyses

Ceramic production, exchange and consumption in the Banda area, west central Ghana has been affected by historical developments ranging from recent competition with alternative vessels (made of metal and plastic) to political economic upheavals that altered community relationships within and outside the region. In this study, we explore spatial and temporal patterning in pottery production, exchange and consumption using a combination of analytical techniques. Instrumental neutron activation analysis (INAA) of a large sample (491 specimens) of archaeological and ethnographic pottery, clay and temper samples from sites across the Banda area has led to the identification of seven compositional groups whose differential distribution implies shifts in resource selection through the last thousand years. Laser ablation-ICP-MS analysis was used to explore the effects of distinctive tempering agents (crushed slag) on the bulk chemical signature of a subset of Banda ceramics, while petrographic analysis provides insight into the preparation of ceramic fabrics. We integrate insights from these diverse physical studies to investigate the dynamics of pottery production, exchange and consumption over the course of the last millennium in the Banda area and explore potential linkages with broader political economic transformations.     

The upper mills quarter of Bamberg: Innovative,adaptive reuse

The Bavarian town of Bamberg had a complex of old mills which had become an eyesore to its citizens. In the late 1970s, work was undertaken to rehabilitate the structures. The end result has been a successful case of adaptive reuse. This is not just another case of adaptive reuse to the extent that it has been innovative. This case is examined in the context of a theory of urban renewal which had been popular and prevalent during the period when Bamberg's most distinctive and distinguished section, Die Altstadt (Oldtown), had to face change.     

Olive oil production on bronze age Crete: nutritional properties, processing methods and storage life of Minoan olive oil

Archaeological studies on olive oil produced in Crete in the Bronze Age focus primarily on aspects such as the period when olive cultivation became widespread, the number of olive trees cultivated, or the quantity of oil stored in the Minoan palaces. Olive oil is however an organic substance, a perishable product, the nutritional and storage properties of which are determined by environmental, agronomic, processing and storage conditions. In this paper archaeological, environmental and biochemical evidence is combined to present a comprehensive picture of the potential quality, nutritional and storage properties of Minoan olive oil. The comparative evidence presented suggests that Minoan olive oil was equal in quality to the cold-pressed virgin olive oils produced today, and as such, the oil was nutritionally important in the Bronze Age and a valuable trade commodity.     

Multilevel (mis)governance of palm oil production

The palm oil industry exemplifies the ‘regionalisation without regionalism’ pattern seen in other industries in Asia: extensive, regionally concentrated transnational economic integration accompanied by a low level of formal regional institution-building. Production is concentrated in Malaysia and Indonesia, and Asian countries account for a major share of the market for intermediate products. The ownership structure of palm oil production reflects the dominance of transnational Malaysian and Singaporean firms. There is no authoritative regional institution governing production, investment standards or labour in the industry. A patchwork of both enabling and regulatory governance institutions supports the industry. These are formal and informal, public and private, and are situated at multiple levels: within, below and across the nation state. Although the governance structure surrounding the palm oil industry has supported it well in terms of production volumes and profits, large externalities—environmental and social costs—persist. This article argues that the governance failures associated with the industry stem from different stakeholders' competing interests in contexts of highly unequal wealth and power distribution. Misgovernance is not an unintended consequence of institutions failing to keep up with markets in scale and scope, but is embedded in the multilevel governance regime that supports, and partially regulates, the industry.     

Framing a survey of textile mills: RCHME's West Riding experience

Abstract

Large numbers of multi-storey textile mills have become redundant in the north of England. In 1984 the Royal Commission on the Historical Monuments of England embarked on a survey of these mills in the former West Riding of Yorkshire. Following a pilot survey in the Worth Valley and Keighley, an initial survey identified 1400 mills and a ten per cent sample has been selected for fuller recording. This article discusses the considerations involved in defining the method and scope of the survey.     

Transitions in Islamic plant-ash glass vessels: on-site chemical analyses conducted at the Raya/al-Tur area on the Sinai Peninsula in Egypt

This study focuses on the chemical composition of Islamic plant-ash glass (dated from the 9th to 11th centuries) excavated from the Raya/al-Tur area on the South Sinai in Egypt. Plant-ash glass objects from the Raya site were classified into three compositional types based on on-site chemical analyses with a portable X-ray fluorescence spectrometer. Based on typological characteristics and chemical composition comparisons with contemporary glass objects from other Islamic sites, one hypothesis holds that plant-ash glass objects produced in the Syria–Palestine or Mesopotamian regions could have been imported to Raya during the 9th to 10th centuries. In particular, some colorless glass vessels with a high magnesium/calcium ratio were noted to exhibit post-Sassanian cut decorations. Conversely, most of the bluish-green plant-ash glass objects from the Monastery of Wadi al-Tur near the Raya site exhibited relatively high levels of aluminum, titanium, iron, and lead. These pieces were likely produced during the Fatimid period (late 10th to 12th centuries), and based on their elemental composition, possibly originated in Egypt. The present work provides a greater understanding of chronological changes in post-9th century Islamic plant-ash glasses and the development of social and commercial networks within the Middle Eastern area.     

Councils, memory and mills: the early development of the Peace of God in Catalonia

The Peace councils which took place throughout west Francia from the late tenth century have long been recognized as complex political, social and ritual events. Discussions of the Peace, however, often neglect the local factors which informed these councils. The earliest councils in Catalonia were characterized by remarkable variety in both their organization and in their objectives. Some elements of these councils reflect longstanding regional traditions. Earlier provincial synods, for example, shared many of the same concerns expressed at Peace councils. Both synods and councils testify to an impressive level of regional episcopal co-operation. The 1027 Council of Toulouges provides a rich opportunity to explore the microsocial and micropolitical alliances and animosities which motivated one council. The monastery of Sant Miquel de Cuixà, whose abbot organized this council and two others, had been developing a network of mills and irrigation canals near the council's site. The choice of the council's site was motivated, in part, by the desire to secure Cuixà's grip on these property rights. The mills near Toulouges are an example of the local impulses which informed early Peace councils; understanding these impulses can contribute to current debates about the Feudal Revolution.     

Change in chemical composition of early Islamic glass excavated in Raya,Sinai Peninsula,Egypt: on-site analyses using a portable X-ray fluorescence spectrometer

The Raya port (eighth to 12th centuries) on the Sinai Peninsula, Egypt, was one of the important port cities for the Red Sea trade. We performed on-site analyses of Islamic glass vessels (used in eighth to 11th centuries) mainly from this site in Egypt using a portable XRF spectrometer. The aim of this paper is to contribute to our understanding of the chemical compositions of early Islamic glass vessels by comparing their archaeological date and typology. In the early Islamic period, glass objects were mainly produced from natron as the soda source. Among the natron glass analyzed in this study, glass vessels with low titanium and iron and high strontium contents, which were probably produced in the Syria–Palestine region, were excavated in the eighth century layer. From the ninth century layer, a large number of samples with high levels of calcium, titanium and iron, probably produced in Egypt, were found. It should be noted that a large number of glass vessels with this chemical composition were found at the Raya site, because this type of glass was rarely reported from other Islamic sites. We finally concluded that this type of glass seems to be produced under a fixed recipe, although some samples contain a colorant or decolorized materials.
