Valuing place/placing value: the elusive normativity of landscape in rural Tuscany

Rural Tuscany has become both a paragon of harmonious beauty and a terrain of legal conflict and recrimination. When they do not resort to essentialist notions of taste, many commentators are prone to explain the ‘preservation’ of Tuscany's countryside as the outcome of locally rooted legislative interventions meant to prevent ‘speculation’ and ‘debasement’ (scempio). Tuscany is indeed the site of layers of normative constraints and guidelines, ranging from local zoning regulations to the expectations associated with UNESCO's World Heritage Site status. Far from being self-evident, however, these normative constructs have been debated in Tuscan society over decades of rapid and often chaotic change. The reinvention of rural Tuscany as a paragon of beauty emerged from the search for an elusive form of coherence and meaning, whose features generated both conflict and accommodations. By focusing on a valley in southern Tuscany which obtained the status of World Heritage Site in 2004 (the Orcia valley), the article shows the power of the circumventions, negotiations and reinterpretations in which rural Tuscans have engaged while navigating the alternative temporalities of global validation, national legitimation and local belongings.     

The colour of the facades in Siena’s historical centre: I. Glazings (calcium oxalate films s.s.) and other finishes on the stone materials of the Cathedral’s main facade

This paper focuses on the long-debated topic of the so-called calcium oxalate films: their origin and meaning but also their age and original appearance. The restoration of the main facade of the Siena Cathedral provided a unique opportunity to this end, thanks to the possibility of an extensive and detailed sampling and (as rarely happens) a sufficiently accurate historical knowledge of the construction vicissitudes. This work, mainly based on a polarising microscopy study (coupled with X-ray diffraction and SEM-EDS analyses) of over a thousand thin and ultra-thin sections of 400 microsamples, demonstrates that the current relicts of films are the result of alteration and decay of ancient treatments. In most cases, these were linseed oil-based glazings (the use of this substance is confirmed by historical documents) and pigments. Their role was essentially aesthetic; their use dates the beginning of the fourteenth century and continued at least until the eighteenth century.

Effects of Confidentiality-Preserving Geo-Masking on the Estimation of Semivariogram and of the Kriging Variance

Geostatistical methods, such as semivariograms and kriging are well-known spatial tools commonly employed in many disciplines such as health, mining, forestry, meteorology to name only few. They are based essentially on point-referenced data on a continuous space and on the calculation of distances between them. In many practical instances, however, the exact point location, even if exactly known, is geo-masked to preserve confidentiality. This typically happens when dealing with confidential data related to individuals-health and their biometric parameters. In these situations, the estimation of the semivariogram and, hence, the spatial prediction can become biased and highly inefficient. This paper examines the extent of the bias in the particular case when the geo-masking mechanism is known (called “intentional locational error”) and lays the ground to a full understanding of the phenomenon in more general cases. We also examine how the geo-masking affects the estimation of the kriging variance thus reducing the efficiency of spatial prediction. We pursue our aims by developing some theoretical results and by making use of simulated and real data analysis.     

Microstoria,Pacific History,and the Question of Scale: Two or Three Things That We Should Know About Them

This article is prompted by the recent debate on the so-called crisis in the humanities, and the related call for historians to change direction by returning to history of the longue durée. While pointing out that the ‘crisis’ is more influenced by the changing political economy of the tertiary education sector than by specific historiographical practices, I suggest that small-scale analysis remains compatible with global history approaches. Articulating a parallel examination of Pacific historiography and the Italian variant of microhistory, the article argues that the latter provides fertile stimuli for Pacific history. In particular, I maintain that integrating social analysis can serve to counterbalance the over-emphasis on cultural aspects found in much Pacific historiography.     

Combining residue analysis of floors and ceramics for the study of activity areas at the Garum Shop at Pompeii

In this paper, we propose the application—for the first time in the Mediterranean area—of the combination of the study of chemical residues in floors and ceramics, with the aim of providing information about the activities carried out in archeological buildings. We chose the Garum Shop at Pompeii to test the method. In fact, due to the peculiarity of this archeological context, it provided an ideal case in which the activities performed are in part known, and the ceramic vessels recovered are still in situ. Floor samples were studied by means of spot tests developed in Mexico aimed at identifying the presence of phosphates, fatty acids, and protein residues, while the organic residues preserved in the ceramic matrix of amphorae, dolia, and other ceramic vessels were studied by gas chromatography coupled with mass spectrometry. Moreover, we integrated the data obtained with specific studies directed at better identifying the solid residues found inside two of the amphorae studied: botanical studies of fruit stones recovered in a Dressel 20 amphora and the characterization of the lime preserved in an African amphora. The research allowed for the identification of the traces of some of the activities performed, such as cooking and producing garum in the floors of the building, and the use and re-use of amphorae and dolia before the Vesuvian eruption.     

Selinunte (Sicily) and its productive context: the clayey raw materials applied in a long-lived ceramic production (seventh to third century BCE)

The westernmost of the Greek-Sicilian towns, Selinunte, founded in western Sicily during the second half of the seventh century BCE, gives amazing evidences of a historic activity of ceramic production (seventh to third century BCE). The present study aims to identify the raw materials available in the vicinity of the archaeological site of Selinunte, which were possibly used by the ancient potters, and to characterise them by means of petrographic and chemical techniques. A sampling campaign of clays and sands for tempering was undertaken in the archaeological site and the adjacent area. Moreover, locally produced archaeological bricks and tiles were considered helpful for comparison regarding the definition of local ceramic macro- and micro-fabrics and were analysed as well. The comparison between textural, mineralogical and chemical data allowed us to highlight a good similarity between the clayey materials available in the area and the local ancient bricks and tiles. Their compositional resemblance suggests the hypothesis of a systematic use of the studied clays for ceramic productions from the Archaic to the Hellenistic period. The preliminary archaeometric results obtained so far could enhance the distinction between local manufactures and imports and may well lead to the identification of ceramic artefacts produced by the Archaic-Hellenistic workshops of Selinunte at various consumption sites.     

The Enlightenment and the church in the work of Franco Venturi: the fertile legacy of a civil religion

The first part of this essay examines the reasons why the relationship between Enlightenment and religion was central to Franco Venturi's studies on the eighteenth century. In part this came from his own strong secular convictions and from the tradition of secular utopian thought in which Venturi came to intellectual maturity in Turin in the first half of the century, but whose origins lay in the eighteenth century. The essay then explores how these interests guided Venturi's choice to themes and topics, and how his understanding of the relationship changed in the course of his life and writings. The second part of the essay considers Venturi's legacy specifically in relation to this central theme, and discusses the works of subsequent scholars (including the author) whose work has most directly taken up and developed Venturi's own concern to explore the origins of different forms of secular religion in the age of the Enlightenment.
