A Multidisciplinary Approach for the Archaeometric Study of Pozzolanic Aggregate in Roman Mortars: The Case of Villa dei Quintili (Rome,Italy)

This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili.     

Provenance Analyses of the Volcanic Rock Grinding Stones from the Greek Colony of Selinunte,Sicily (Italy)—Constraints and Possibilities

The petrography as well as the major and trace element compositions of the Selinunte grinding stones, made of grey vesicular lava, were analysed. By comparison with geochemical data from volcanic rocks in the Mediterranean, we were able to determine that only a minor number of the tools were extracted from the nearest volcanics of Mount Etna and the Hyblean Mountains, while the majority of the grinding stones were most probably imported from the Aeolian Islands, although an origin from the Aegean cannot be excluded entirely. The results are important in order to scrutinize trading connections, especially for the earlier times of settlement during the sixth century bc .     

The Provenance of Historical Gunpowder from South‐Western Japan: A Stable Isotopic Approach

Stable isotopic analysis was undertaken for the gunpowder ingredients from crude saltpetre and propellants from several types of gun that prevailed during the late 19th century in south‐western Japan. Stable isotopic signatures for δ¹⁵N_{saltpetre nitrogen}, δ³⁴S_{native sulphur} and δ¹³C_{charcoal carbon} in crude saltpetre, gunpowder magazines bearing the trademark of mills from southern Scotland and cartridges for an improved Sharps rifle (with a US trademark) all imply common assemblages from the same source (saltpetre and native sulphur from British India and Sicily, respectively) in the United Kingdom (UK). One Pritchett patron is common for muzzle‐loading Enfield rifles, while the other suggests a four‐allied lead bullet for an unidentified hand gun. Propellants in the Pritchett patron from the same institution also suggest a common source of these rifles. On the contrary, the ingredients for an unidentified rifle and time fuse for a Paixhans gun with unique stylistic devices showed distinctive isotopic signatures, indicating a local Japanese origin. The Pritchett patron from the Kumamoto Museum involved a mixed provenance from the UK and Japan. The stable isotopic analysis provides direct evidence for the ultimate origin of the propellant.     

Coarse cloth and clerical tailoring: negotiating Boston-Irish cultural imperatives in the Famine era

Recent calls for updated approaches to the Irish-American historical experience recommend more systematic attention to complexities inherent in Irish immigration and settlement. They also seek further contextualisation of the history of the Irish in the USA within broader North American, transatlantic and global frameworks. The need to review and potentially reappraise longstanding, essentialist perspectives on Irish arrival and assimilation is equally evident. This article expands on foundational narrative histories of the Boston Irish to re-examine Famine-era settlement and contending agendas within spheres of religious affiliation and political activism. The character and evolution of Irish-American ethnic identity, and the tragic imprint of the Famine under consideration here pave the way for new readings of traditional orthodoxies. Collectively, they reveal Boston's Irish historical terrain to be more complex than the record currently suggests.     

Life and Death in Neolithic Southeastern Italy: The Strontium Isotopic Evidence

There is a strong relation between people's structured identities and their chemical biographies: these can reflect the way individuals choose to reside and/or move. The strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) of skeletal remains is considered a useful proxy to assess residential mobility and social practices in past populations; however, so far, it has only occasionally been applied to prehistoric contexts in the Mediterranean. In this paper, we present ⁸⁷Sr/⁸⁶Sr data of human and animal samples from several Neolithic sites in the Apulian Tavoliere (southeastern Italy), namely, Grotta Scaloria, Passo di Corvo, Masseria Candelaro and La Torretta/Poggio Imperiale. Data obtained from dental enamel reflect the local origin of the individuals and allowed us to differentiate function and meaning of the sites examined. In particular, within a generally homogeneous background of Sr signatures, the range of ⁸⁷Sr/⁸⁶Sr at Scaloria Cave is greater than at the other sites, with variation likely to be related to funerary practices. We interpret this as the evidence of the ritual use of the cave, which implied the gathering of people of different origin. The relative variation of the Sr signature among individuals, either intersite or intrasite can be tentatively associated with mobility during life as well as with social practices, such as access to foods from geologically different environments.
