Thermal and Petrographic Characterization of Herculaneum Wall Plasters

Roman plasters sampled from different houses at the archaeological site of Herculaneum, Italy, (2010–12) were studied by means of petrography, thermal analysis and X‐ray fluorescence. Herculaneum plasters are composed by preparatory layers (arriccio) with a thickness of several centimetres and are based on a calcitic binder and volcanic scoriae as aggregates, covered by a thin final layer characterized by a low granulometry. Most of the sampled plasters can be placed into two groups based on the aggregate composition and classified as marmorino or intonachino. However, a similar aggregate composition did not induce superimposable thermal behaviour, thus suggesting that the samples underwent different ageing/weathering processes, with a consequent change of the ratio among the components.     

Forty Thousand Arms for a Single Emperor: From Chemical Data to the Labor Organization Behind the Bronze Arrows of the Terracotta Army

This paper explores the integration of chemical data with metric studies and spatial analyses of archaeological artifacts to investigate questions of specialization, standardization, and production organization behind large-scale technological enterprises. The main analytical focus is placed on the 40,000 bronze arrowheads recovered with the Terracotta Army in the First Emperor’s Mausoleum, Xi’an, China. Based on the identification by portable X-ray fluorescence spectrometry of chemical clusters that correspond to individual metal batches, and combined with a study of their context in the tomb complex, we argue that the manufacture of arrows was organized via a cellular production model with various multi-skilled units rather than as a single production line. This system favored more adaptable and efficient logistical organization that facilitated dynamic cross-craft interaction while maintaining remarkable degrees of standardization. We discuss the use of “the batch” as an analytical category and how our method might be applied to other studies of craft organization in complex societies and imperial systems.     

Our Dear Cousins the Americans: Sara Jeannette Duncan in Washington

As a young woman, Canadian author Sara Jeannette Duncan (1861–1922) spent nearly a year writing for the Washington Post on literary and cultural matters, and published many of her assessments of American society in The Week, Goldwin Smith's journal of Canadian affairs. Her articles repay close scrutiny not only for their inherent interest as witty observations of America by an engaged Canadian observer, but also for the manner in which they reveal Duncan's national preoccupations and biases. Approaching the Republic with neither antipathy nor deference, Duncan turned her newspaper sketches into an occasion for wide-ranging cultural comment on the nature of the republican experiment – especially concerning America's claims to freedom and human flourishing. She found the results encouraging, if not without salutary warnings, for Canadian efforts in the same direction.     

Canadiana Abroad: The Department of External Affairs' Book Presentation Programmes, 1949–1963

This article examines one aspect of Canada's early cultural diplomacy. During the late 1940s, the Department of External Affairs frequently received requests for Canadian books from foreign libraries. At the same time, many officials were eager to promote Canadian culture abroad. The Annual Book Presentation Programme was inaugurated with the intention of creating “repositories of Canadiana” which might stimulate interest in Canada among foreign readers. Although the budget for the program was always modest, over the years the department's book gifts did fulfill their aim, creating a basis for the later growth of Canadian studies in universities abroad.     

Developing a Collaborative Strategy to Manage and Preserve Cultural Heritage During the Libyan Conflict. The Case of the Gebel Nāfusa

The paper discusses the potential of a collaborative scheme for the development of a protocol for recording and managing the cultural heritage in Libya. The critical political situation in the country urges the development of cultural heritage management policies in order to protect it more thoroughly and consistently. Moving on from the numerous international initiatives and projects dealing with a mostly “remote” approach to the issue, the project here presented to engages with staff members of the Department of Antiquities (DoA) in the development of a joint strategy for the application of remote sensing and geographical information systems (GIS) to the preservation and monitoring of Libyan cultural heritage. A series of training courses resulted in an initial development of new ways of recording and analysing field data for a better awareness of the full range of threats that the archaeology of the country is subject to. Focussing on the case of the Jebel Nafusa, the training involved the assessment of site visibility on satellite imagery, the analysis of high-resolution satellite datasets for archaeological mapping, the creation of a GIS spatial database of field data, and the mapping of risks and threats to archaeology from remote sensing data. This led to the creation of of a risk map showing the areas that are affected by a number of threats, thus giving the DoA a tool to prioritise future fieldwork to keep the assessment of site damage up to date. Only a collaborative approach can lead to a sustainable strategy for the protection of the invaluable cultural heritage of Libya.
