German volunteers in the armed conflicts of the Italian Risorgimento 1834–70

Abstract

Between 1834 and 1870, Germans participated in the armed conflicts of the Italian Risorgimento in the ranks of both Mazzini and Garibaldi and of the Pope and Francis II of Naples. While acknowledging the difficulty in analysing the motives of historical actors, the essay compares the reasons that led these Germans to volunteer and fight. For those who fought for the cause of Italian unity, the networks created in exile in the 1830s remained decisive down to 1870, whereas the mobilization of volunteers in Germany for the Papal states reached its height only later between 1867 and 1870. Despite these chronological differences, the methods used in terms of the media and forms of organization to mobilize the volunteers and to legitimize war were very similar across the political spectrum. The foreign volunteers were described by their own side as brothers, but as mere mercenaries by the respective enemy side. At the same time, Germans and Italians brought their national stereotypes to the various armed groups and armies in which they served and in ways that made the latter important places for the staging of national ‘re-virilization’ achieved through heroic fighting.     

ATTENUATION RELATIONSHIP FOR LOW MAGNITUDE EARTHQUAKES USING STANDARD SEISMOMETRIC RECORDS

Northwestern Italian weak-motion data were used to study attenuation characteristics of horizontal peak ground acceleration (PGA) and horizontal peak ground velocity (PGV) from earthquakes of local magnitudes (M _l ) up to 5.1. Data have been provided by the RSNI (Regional seismic network of Northwestern Italy) and RSLG (Regional seismic network of Lunigiana-Garfagnana) waveform database. The database consists of more than 14000 horizontal components recorded in the period 1999-2002 by both broadband and enlarged band seismometers. The accuracy of the procedure used to extract PGA values from the velocity recordings was verified comparing observed and derived PGA values at station STV2, which was equipped with both a temporary K2 Kinemctrtcs accelerometer and Guralp CMG40 broadband sensor. The attenuation of both peak ground acceleration and peak ground velocity was found to be logarithmically distributed with a strong attenuation for low distances (less than 50 km) and low M _l values (<3.0). The resulting equations are:

Log(PGA)=?3.19+0.87M?0.042M ²?1.92 Log(R)+0.249S,

Log(PGA)=?4.23+0.76M?0.018M²?1.56 Log(R)+0.230S,

where PGA is expressed in g, PGV is expressed in m/s, M is local magnitude, R is the hypocentral distance in kilometers and S is a dummy variable assuming values of 0 and 1 for rock and soil respectively. For increasing distance and magnitude, both PGA and PGV values show a linear distribution. The validity range of the obtained attenuation relationships is 0–200 km for distances and M _l up to 4.5. Sensitivity studies performed by analysis of residuals, showed that predicted PGA and PGV values are stable with respect to reasonable variations of the model and distances providing the data. Comparisons with attenuation relationships proposed for Italian region, derived from strong motion records, are also presented.     

Attenuation Relationships for Iran

The purpose of this study is to derive the attenuation relationships for PGA, PGV, and EPA parameters for areas within the seismic zones of Zagros, Alborz and Central Iran with rock and soil substructures. In order to do so, at first the available scientific data including the methods used for deriving attenuation relationships and the parameters involved have been gathered. Afterwards, all the efforts have been focused on gathering a thorough catalogue of earthquakes occurred in Iran. In this regard, a majority of the available catalogs in Iran have been gathered and corrected through different methods and finally a set of 89 earthquake events including 307 earthquake records with reliable data was chosen.

Since in order to derive the attenuation relationships it is essential to extract the parameters from the acceleration records, a great effort was placed on gathering the earthquake acceleration records of Iran. This resulted in building a database of a majority of the earthquake records up to the year of 2004. Afterwards, correction methods applicable to earthquakes records of Iran considering the type of machines used and the ground type were examined which resulted in certain guidelines for correction of earthquake acceleration record data related to Iran.

In the next step the needed parameters were extracted from the earthquake acceleration record data which were consequently divided into two seismic zones of Zagros, and Alborz and Central Iran according to tectonic conditions. After examination of the parameters and choosing the most appropriate among them, the attenuation relationships were derived for such parameters.     

Raman Spectroscopic Analysis of Ancient Egyptian Pigments

The application of FT‐Raman spectroscopy and visible Raman microscopy to the non‐destructive analysis of pigment specimens excavated from Tell el Amarna by Flinders Petrie in the 1890s has provided information about the chemical composition of the materials used by XVIIIth Dynasty artists in the New Kingdom at the time of King Akhenaten, c. 1340 bc. Comparison of the Raman spectra of the samples labelled ‘red and yellow ochre’ with documented, archival material from geological collections provided a clear indication of the materials used in the iron(III) oxide/hydroxide system, including α‐hematite, goethite, maghemite, magnetite and lepidocrocite. The yellow–orange specimen labelled ‘realgar’ proved to be a mixture of realgar and pararealgar; since the specimen had been sheltered from light since its excavation, this could indicate that the ancient Egyptian artists recognized the colour variation and may have used this to effect in their decorations. A specimen of yellow ochre contained goethite, α‐FeO.OH, with particles of crystalline, highly ordered graphite; in contrast, the red ochre specimens contained amorphous carbon particles.     

The Possibility of Provenancing A Series of Bronze Punic Coins Found At Tharros (Western Sardinia) Using the Literature Lead Isotope Database

A sample set of 42 bronze Punic coins dating from the third century bc and excavated in the Phoenician, Punic and then Roman town of Tharros (western Sardinia) has been used to test the performance of the literature lead isotope database and to establish a well defined provenancing procedure. A selection from the available database, including Cypriot, Sardinian and Spanish ore deposits, has been used. The complete assignment has been carried out twice, using both statistical methods (linear discriminant analysis) and the conventional raw data plots. Three major and one minor disagreements have been found, suggesting that the two procedures, when properly employed, may be acceptably compatible. Almost one third of the coins exhibit a characteristic Cypriot signature, whereas only very few samples are compatible with Sardinian ores. However, the majority of the coins (c. 60%) cannot be associated with any known source, which suggests the possibility of extensive metal recycling.     

Roman Millstones from Orvieto (Italy): Petrographic and Geochemical Data for A New Archaeometric Contribution

The probable site of extraction and production of Pompeian‐style leucite‐bearing millstones, singled out by Peacock (1980, 1986) in the vicinity of Orvieto, and the outcropping of the ‘Leucitophyre’ lava have been systematically studied employing standard petrographic and geochemical methods (optical microscopy and ICP–AES/MS spectrometry). The combination of petrochemical data, previously very poor, allowed us definitively to exclude the possible ‘overlap’ of phonolitic and tephri‐phonolitic lavas from other Quaternary Volcanic Districts of Latium, and provides a helpful tool for future work on leucitite millstones. Consequently, the databank obtained has been used to attribute the origin of five Roman millstones discovered in three archaeological sites in central Italy (Latium and Marche). It has also been useful to verify the geological provenance of some Sicilian and French leucitite millstones analysed by previous workers. The results point to a provenance from the Orvieto area, with the exception of the millstones from Sicily, for which a different origin was hypothesized.     

Mineralogical And Chemical Investigations Of Bloomery Slags From Prehistoric (8th Century Bc To 4th Century Ad) Iron Production Sites In Upper And Lower Lusatia,Germany

More than 400 fayalitic bloomery slags from prehistoric iron production sites in Upper and Lower Lusatia, eastern Germany, as well as bog iron ore samples and intermediary samples of the smelting process, were analysed by chemical and mineralogical techniques. While the precursor bog iron ores exploited in the two regions under investigation were very similar in composition, consisting of low‐manganese/low‐barium as well as high‐manganese/high‐barium types of ore, pronounced differences in slag composition were detected. Slags from 17 investigated sites in Upper Lusatia showed average P₂O₅ contents between 1 and 3 mass%, whereas slags from 15 investigated sites in Lower Lusatia were generally much richer in phosphorus, reaching values as high as 7 mass% P₂O₅. Since a reasonable correlation exists between calcium and phosphorus contents in the slags of the latter sites, it is conjectured that deliberate addition of CaO to the ore/charcoal charge of the bloomery furnace may have taken place in order to fix the phosphorus in the slags effectively. In many samples, this conjecture is being supported by the detection of a slag mineral Ca–Fe phosphate Ca_9?xFe_1+x(PO₄)₇ that presumably crystallized from a residual phosphorus‐rich melt and shows a cotectic relationship to both Ca‐rich fayalite and wustite, as well as to members of the solid solution series magnetite–hercynite.     

Assessing Ceramic Compositional Data: A Comparison of Total Reflection X‐ray Fluorescence and Instrumental Neutron Activation Analysis On Late Iron Age Spanish Celtiberian Ceramics

A solid‐phase, non‐chemical processing protocol was recently developed as a means of chemically characterizing archaeological ceramics by total reflection X‐ray fluorescence (TXRF). Following this methodology, TXRF can provide semi‐quantitative determinations for 18 elements with comparable levels of precision and accuracy for the majority of them in comparison with a clay reference material analysed by instrumental neutron activation (INAA). In order critically to assess the analytical capabilities of TXRF, a large sample set of Late Iron Age Spanish Celtiberian ceramics and modern clays was analysed both by TXRF and INAA. Semi‐quantitative chemical data provided by TXRF and quantitative data provided by INAA were subjected to commonly used multivariate statistical methods as a way of evaluating the ability of the new technique to discriminate among different compositional groups. The comparison of the two data sets shows no significant discrepancies, thereby allowing support for the same archaeological interpretation. These results suggest that TXRF has potential applicability for compositional characterization of archaeological ceramics, providing data that are useful for provenance studies.
