Anselm Kiefer: a study of his artistic materials

The style of the contemporary German artist Anselm Kiefer is highly innovative and unconventional and is characterized by the use of diverse materials that he selects and combines according to the emotions that they stir in him. The conservation and preservation of works by Kiefer are particularly difficult tasks because of the heterogeneity and, in some cases, the incompatibility of the materials used; therefore, a thorough characterization is crucial before any intervention is considered. In this paper, we report the results of an investigation on a fragment from a multimaterial work and on samples from the paintings Bohemia Lies by the Sea and Die Größe Fracht. The large fragment was cut by the artist himself from a work in progress and is considered destitute of any artistic value; therefore, it was possible to sample it extensively. This fragment and the samples from the Die Größe Fracht and Bohemia Lies by the Sea paintings were analyzed by ultraviolet (UV) fluorescence imaging, fiber optic reflectance spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, Raman spectroscopy, X-ray diffraction, gas chromatography-mass spectrometry, and pyrolysis gas chromatography-mass spectrometry. This multitechnique approach allowed us to fully characterize and identify pigments, dyes, and organic components that reflect the diversity of the materials typically chosen by the artist. The results are evaluated in the context of the interview that Antonio Rava had with the Anselm Kiefer in 2000.     

Macroscopic analysis of the bead assemblage from the South Arabian port of Sumhuram,Oman (seasons 2000–2013)

The city of Sumhuram (300 BC–AD 500) is the most important pre‐Islamic settlement in Dhofar, southern Oman. Since the time of its discovery it was evident that its commercial vocation placed it within a complex system of exchange between India and the Mediterranean. Sumhuram was a key site of the kingdom of Hadramawt, built in a place that was geographically strategic to control the most important Indian Ocean trade routes. The importance of the site made the bead assemblage exceptionally rich in materials, technologies used in the production, and provenance. The study of the relationship between materials and shapes, necessary for the creation of a specific typology, has revealed a number of trends. These, in connection with the reference stratigraphy have, in some cases, enabled the identification of differences on a chronological basis. Furthermore, it is possible to detect different uses of materials in different areas of the city. The variety of imported products (raw materials and products) once again underlines the importance of this city‐port in the international maritime trade and its strong connections with India.     

Dialectical movements with the Toba people in the Argentine Chaco

Since 1998, I have undertaken fieldwork with the Indigenous peoples of the Argentine Chaco, focusing initially on their dances and embodied practices. After this ethnographic research, I began to think more deeply about the relationships between fieldwork and reflexivity and the possibilities of redefining analytical categories in the global South. The purpose of this article is to revisit my emphasis on a ‘dialectical approach to embodiment’ as a starting point for analysing cultural transformation in Latin America. I argue that this methodological approach has been closely linked to the interweaving of conflicting embodied experiences and peripheral geopolitical locations. In this regard I analyse how the contradictory experiences identified in my fieldwork with the Toba people, and also in my intersubjective and geopolitical positions as a Latin American academic woman, led me to a critical re-examination of dialectics. Further, I describe how this methodological approach, while well received among Latin American scholars has to some degree been resisted by (North) American and British scholars, and I explore the geopolitical implications of these disparate academic positions. Through these critical movements, I hope to contribute to rethinking dialectics in postcolonial contexts, adding some embodied voices from the Latin American South.     

The Archaeology of Poverty and Human Dignity: Charity and the Work Ethic in a 1930s Depression Era Itinerant’s Camp on the Toowoomba Range Escarpment, Queensland

This paper outlines the ethnohistory and archaeology of a Great Depression camp for unemployed men, established at Toowoomba, Queensland, in 1932. The camp was self sufficient and highly ordered. We interpret the material signature of the camp as a symbol of main-stream middle-class Australian values. Thus the camp is also a material symbol of the work ethic central at this time to notions of human dignity, respect and the moral development of individuals. We conclude that the archaeology of the camp demonstrates a strong work ethic among the ‘inmates’ and a degree of visible charity enabled by the historical concept of the ‘deserving poor’.     

Effect of organic and inorganic consolidation agents on Tlaltecuhtli monolith

A huge monolithic piece corresponding to the first years of the sixteenth century has been discovered in Mexico City. It represents the earth goddess Tlaltecuhtli. The preservation of such a magnificent piece is imperative. Therefore, the surface has to be characterized and the interaction of consolidants with the rock has to be understood.Some of the consolidation methods are impregnation of the mineral with nopal or silicic acid derivatives. In this work we compare the physico-chemical effects of organic and inorganic consolidants. Original and impregnated samples are characterized with a series of original techniques: X-ray diffraction, nuclear magnetic resonance, nitrogen adsorption and small angle X-ray scattering. Fractal dimension, specific surface area and pore size distribution clearly differentiated the samples. The organic materials, nopal gum or slobber, cover the mineral particles with a smooth layer. The KSE solutions react and lead to microporosity.     

Cooked Bones? Method and Practice for Identifying Bones Treated at Low Temperature

Is it possible to determine low‐temperature cooking in archaeological bones? The indirect exposure of bones to fire at low temperature (≤ 100 °C), linked to cooking, produces macroscopic modifications on these bones. These modifications have not been clearly or systematically described previously. Instead, physicochemical changes at nanometric level are only now beginning to be understood. In this paper, our principle aim is to explore new methods and techniques that correlate macroscopic features such as smoothness or light transparency with physicochemical characterization results that could aid towards detecting cooked bones in the archaeological record. This study then selected 11 archaeological samples, both human and non‐human. Bones were considered to be thermally treated or not, on the basis of macroscopic criteria. Complementary characterization techniques were used to study morphology (scanning electron microscopy and small angle X‐ray scattering), structure (X‐ray diffraction and transmission electron microscopy), local composition (energy‐dispersive X‐ray spectroscopy) and texture (gas adsorption). Indeed, fractal dimension, particle size, crystalline percentage or specific surface area may well explain some of the macroscopically observed modifications on these samples. The possibility that such apparent modifications may also be due to diagenesis is also considered. From an archaeological point of view, the results are promising. Our characterization of human and non‐human bones demonstrates that physicochemical techniques are complementary and provide good criteria against which to distinguish boiled from un‐boiled archaeological samples.

Production of the Roman Cement in Italy: characterization of a raw material used in Tuscany between 19th and 20th century and its comparison with a commercialized French stone material

An experimental approach in order to investigate the possibility that some Italian limestones were used for the production of Roman Cement is proposed. Three types of Pietra Alberese, a marly limestone used since Roman times for the production of “lime” in Tuscany (Italy), were selected. By burning of these stones, specimens of binders were realized. The characteristics of these binders were compared with the binder obtained by burning a French marly limestone commercially used for the production of Roman Cement.

All samples of carbonate stones were preliminarily characterized from the chemical, mineralogical, and petrographic point of view. The colorimetric coordinates were measured on both rock samples and hardened binder samples. The analysis carried out shows that Pietra Alberese with an high content of clay minerals develops a similar microstructure with respect to that developed by the French marly limestone used for the production of Roman Cement.     

The Non-Sense of an Ending

This article contributes to the scholarship on Portuguese writer José Cardoso Pires as well as the study of the neorealist short story in Portugal. It analyzes the ending of the neorealist short story as a moment of utopian projection and draws a comparison with Cardoso Pires's short story endings. This study demonstrates that Cardoso Pires displaces the ending of the story as a moment of concordance to a moment of continuing crisis. The author suggests that through the design of problematic narratorial voices that advance ambiguity and irony, Cardoso Pires requires from the reader an engagement with the text that mirrors the writer's engagement in society.     

Geography of belonging: nostalgic attachment,transnational home and global mobility among Romanian immigrants in Spain

This article explores how human global mobility is linked to a sense of home and belonging and outlines ways in which European Union (EU) enlargement could contribute to broader debates about migration, both empirically and theoretically. To accomplish this aim, I use the context of Romanian migration to Spain. Since EU enlargement in 2007, Spain has emerged as a major destination for Romanian migrants. The main argument of the paper is that transformations in the EU over the past 20 years through its open border policy have changed migrant workers into EU movers, and this change affects people's perceptions about sense of home. This analysis is prompted by a qualitative and narrative turn in migration studies, and an emphasis on new mobility pathways in accounting for the embodied dimensions of migration. Key to the paper is an analysis of how people can maintain a sense of home while being on the move. It attempts to demonstrate that migrants' experiences of belonging in their host country may vary greatly depending on the time of movement, the politics of EU borders, the nature of mobility and personal and individual circumstances.
