In defence of Rome: a metallographic investigation of Roman ferrous armour from Northern Britain

Metallographic examination of seven different types of Roman ferrous armour from northern Britain dating between the late first and the early third century has revealed a complexity and variety of structures. Five specimens were made of iron hardened by warm or cold working. One fragment was of medium-carbon steel and one was of iron carburised to steel on the outside surface. Four pieces were made from folding sheets of iron or steel, variously the same piece or different metals, each with a thickness of <1 mm. Hardnesses ranged between 187 and 438 Hv. There was no evidence that the specimens had been quenched hardened or quenched and tempered.     

Roman soil and Roman sound in Irish hagiography

ABSTRACT

Irish hagiography displays considerable interest in communication between Ireland and Rome, particularly as this featured saints, popes and relics. While people and objects travel between the two places, there is also concern to circumvent the distance involved. This article discusses an episode of miraculous communication in the Irish Life of St Colmán Élo. Here messages and messengers travel from Rome, but time and space are also telescoped through aural and material means: the sound of the bell marking the death of Pope Gregory the Great and a gift from him of Roman soil to be spread on Colmán Élo’s cemetery. The article considers how the two elements function within their hagiographical context to connect Rome and Ireland, and how these places shaped the account. The roles of bell and soil both draw on their associations in Ireland and relate to papal communication as this was experienced and imagined more widely.     

Beginning geography: a human and technical perspective

Abstract

A first course in human geography has been designed for majors and students from the more technical fields at university. It is built around five computer exercises, none of which require any programming or computer skills. Problems and exercises are designed to enhance carry‐over skills and humane awareness.     

Stable isotopic evidence for diet in a Roman and Late Roman population from Leptiminus,Tunisia

This study investigates the diet of the Roman and Late Roman population of Leptiminus on the Mediterranean coast of Tunisia. Stable carbon and nitrogen isotope analysis of human bone collagen and carbonate samples obtained from individuals buried in four cemeteries at Leptiminus was conducted in order to reconstruct the diet of the population, investigate the relative importance of marine vs. terrestrial resources, explore sex-, age-, and status-based variations in diet, examine temporal changes in the types of foods consumed, and compare the diet at Leptiminus with that of other Roman populations. The results of this study indicate that the residents of Leptiminus consumed a diet that was heavily reliant on terrestrial plant resources with the addition of a significant amount of marine resources. There were no significant sex differences in isotope values. In contrast, distinct dietary differences were seen between the adults and children. Nitrogen isotope values suggest that weaning began before the age of two and was completed by about 3 years of age, a finding consistent with previous isotopic studies of Roman samples. A temporal shift in diet is suggested by the nitrogen isotope values measured in samples from the most recent cemetery. A comparison of the data from Leptiminus with that derived from other Roman sites indicates that regional variability in diet existed within the Empire.

Roman double-layered crucibles from Autun/France: a petrological and geochemical approach

Eighteen double-layered crucible fragments found in an archaeological excavation site of the Lycée militaire (Autun/France), which dates to the Gallo-Roman period, were analysed with a series of classical mineralogical techniques in order to obtain knowledge about the raw materials of the individual layers. This work focuses on the usage of the crucibles as well as technical aspects of their production. The crucible fragments were studied by using petrographical (optical microscopy), elemental (SEM-EDS, EMPA, XRF-WDS) and mineralogical (XRD) techniques.
