Governing the passions: Sketches on Lodovico Antonio Muratori's moral philosophy

Muratori has often been portrayed as a moral philosopher who represented the traditional neo-Aristotelian mainstream of Italian intellectual life in the early part of the eighteenth century. His loyalty to Christianity as a basis from which societies ought to be reformed has determined his reputation as a ‘pre-enlightened’ thinker. Yet, it is argued here that not only was Muratori very much in touch with the state of the art of early eighteenth-century moral philosophy, but also that he was really a historian with political interests who came to develop a renewed Christian moral philosophy as a tool to respond to the political challenges of the time. Fallen man's preference for self-preservation to natural freedom prepared him for engaging in increasingly sociable contexts that required further self-disciplining and moral improvement. Thus, man cultivated his fallen condition into prudence and ultimately developed a capacity both for charity and for functioning in modern commercial societies.     

Pests in an ancient Egyptian harbor

Our investigations combine detailed identification and interpretation of plant remains and associated fauna and their mode of arrival in one of the rock-cut galleries, Cave 3, at the site of Mersa/Wadi Gawasis on Egypt’s Red Sea coast. The site served as a staging area and harbor from which Middle Kingdom pharaohs launched seafaring expeditions to the land of Punt in the early second millennium BC. Quantities of wood, including ship timbers, fastenings, debris related to ship dismantling and reworking, and charcoal were excavated and analyzed. Evidence of marine mollusk infestation (shipworm) was abundant in Cave 3, as were the remains of insect pests of stored foods. We also report on a unique find of a plaster “spill” that preserved the floor of Cave 3 as it was when people worked in the gallery ca. 3800 years ago. The plaster spill created a sealed deposit of plant and insect remains with a diagnostic ceramic fragment, allowing us to securely associate insect remains and “hollow” spikelets of emmer wheat (Triticum dicoccum) recovered from the gallery. An impression of the beetle Trachyderma hispida and its associated exoskeleton fragments provide new evidence of this species as a potential pest not yet reported from an archaeological grain storage site in Egypt. The finding of Tenebroides mauritanicus from the same deposit is the earliest known association of this pest with stored grains. These unique finds shed new light on the risks associated with preserving food supplies, combating pest infestation, and dealing with marine organisms on land and at sea in the pharaonic harbor.     

Interdisciplinary approach for reconstructing an alder-based historical agricultural practice of the Eastern Ligurian Apennines (NW Italy)

Data from four soil profiles studied through pollen and macroscopic charcoal analyses were used to identify specific palynological assemblages associated with a traditional land-use system documented in the Eastern Ligurian Apennines (NW Italy) between the 18th and early 20th century, concerning a cyclical use of grey alder plots for temporary cultivations involving to the use of controlled fire. This is the first attempt to verify on palynological evidence some hypotheses raised by previous historical ecology studies about the consequences of this agricultural practice (recently named alnocoltura) on past and present vegetation. Our investigations underline (1) high percentages of anthropogenic pollen indicators, (2) increase of Ericaceae percentages, (3) low pollen percentages of Alnus, (4) high macrocharcoal concentrations and (5) high values of palynological richness during periods affected by the alnocoltura cycle according to the historical sources. Similar patterns are also detectable in pollen diagrams from two adjacent peat bogs. The paper shows the strength of an interdisciplinary methodology (field observations, cartographical and archival historical data, palynological and archaeological investigations) for studies of past land-use systems. By demonstrating the necessity of a long-term prospective in environmental reconstructions for the preservation of the cultural landscape, one of the important elements of this research is its potential contribution to issues of habitat management and nature-conservation policy. Further analyses are needed to test the replicability and reliability of the hypotheses derived from this study.     

Two Byzantine Albanian icons: a non-destructive archaeometric study

The present work is part of a project aimed at studying the pigments and painting techniques used by Albanian iconographers to produce Byzantine and post-Byzantine icons dating from the fourteenth to the nineteenth centuries; the state of conservation of these icons was also explored. Inorganic pigments are identified by means of X-ray fluorescence, reflectance spectrophotometry and UV fluorescence analysis. These analysis techniques were performed to discriminate between pigments on the basis of their typical features. Moreover, the study of the optical properties of paintings is of fundamental importance for correct restoration. This work enabled us to recognise the palette used in two artworks by anonymous painters of the fourteenth and fifteenth centuries. Only three small samples were taken from the edge and the back of the wooden tables in order to achieve information on preparatory layers. Twelve to fourteen non-destructive measurements were made to characterise the palette used by the two anonymous painters.     

Seeds/fruits,pollen and parasite remains as evidence of site function: piazza Garibaldi – Parma (N Italy) in Roman and Mediaeval times

Archaeobotanical analyses were carried out on layers from the site of Piazza Garibaldi in Parma, a town located in the plain of Emilia Romagna, in northern Italy. The layers dated to the 3rd–2nd centuries BC, around the time of the foundation of the Roman town, and to the 10th–11th centuries AD. According to archaeological data, the site was a sacred area in Roman times, while it was a market square in Mediaeval times. Data from pollen and seeds/fruits were useful for both palaeoenvironmental and palaeoethnobotanical reconstructions, and together with NPPs including parasite remains contributed to add details on the function of the site in the different chronological phases.     

Experimental Characterization of Ancient Metal Tie-Rods in Historic Masonry Buildings

Metal tie-rods play a decisive role in the control of horizontal thrusts in historic masonry buildings. The main goal of the present study is to investigate the relationship between metallurgical and mechanical properties of original tie-rods in order to contribute to a wider study on ancient building stability and their restoration protocols. This article presents the results of an experimental test campaign carried out on 14 historic tie-rods (dating back from 16^th–19^th century) recovered from restoration works or building demolitions. Stress-strain mechanical tests showed that the elastic modulus of the material is comparable to that of modern structural steel, while the strength and the elongation capability are significantly lower, with a large scatter. Further analyses based on metallography allowed us to assess that this mechanical behavior depends on the heterogeneous nature of the material, which can eventually be compared to a composite with vitreous elongated particles in a ferritic or ferrito-pearlitic matrix. The origin of such metallurgical condition is related to the iron making based on direct smelting from ores.     

Digital heritage research re-theorised: ontologies and epistemologies in a world of big data

ABSTRACT

This article provides the first theoretical treatment of the ontologies and epistemologies of digital heritage research at the time of the interconnected and social web, based on extensive empirical and analytical investigation. We draw on observations and concepts developed while conducting the first study of public experiences of the past that utilised big data – over 1.4 million Facebook posts, comments and replies – to revisit or generate new theory from the ground up. We expect that this will help scholars from a range of fields in the humanities, social and computing sciences who are interested in undertaking digital heritage research to understand the deeper implications of their work, the complexities and limitations of the knowledge they create, and its value in exposing the processes via which heritage is made and assessed.
