Enhancing Understanding of the Emergence of Global Trade: Analysis of 17th‐ to 19th‐Century Spanish Coins Recovered from Western Australian Shipwrecks Using Laser Ablation – Inductively Coupled Plasma – Mass Spectrometry (LA–ICP–MS)

This research uses legacy data from shipwrecks to further our understanding of global silver movement in the 17th to 19th centuries by analysing a collection of silver coins held by the Western Australian Museum. Three hundred and eighty‐nine silver coins were analysed for their trace element fingerprint in order to identify provenance. The coins are a selection from the ships Batavia, Vergulde Draeck, Zuytdorp, Rapid and Correio da Azia, all wrecked off the coast of Western Australia between 1629 and 1816. Analysis was undertaken using laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS), a relatively non‐destructive technique with a sensitivity of parts per million to parts per billion. Data were interpreted using linear discriminant analysis (LDA), which allowed the coins of known provenance to be sorted into identifiable subgroups on the basis of their trace and minor elemental fingerprints, while 27 unidentified coins were compared with this database and their mint of origin predicted. These results have implications for the provenance determination of archaeological artefacts of many materials.     

Women in the Formal and Informal Economies of Late Eighteenth‐Century Quebec, 1763–1830

This article challenges the conventional interpretation of the transition from French to British rule in Quebec, which has emphasised the increasing marginalisation of women in the colonial economy. Using hitherto unexplored criminal and civil court records and newspaper advertisements, reveals that women and in particular married women, both French and English speaking, were active in all facets of business life. Given the importance of imported British luxury items in the colonial economy following the American Revolution, this article argues that women occupied a particularly dynamic segment of business life in Quebec, and were especially prominent in the critical textile and fashion trades. A major theme of this article is to show the significance of informal trade networks in expanding economic development in the late eighteenth century, where women were demonstrably key players. The presence of women in both formal and formal economies goes far to locating Quebec in a burgeoning Atlantic economy, and to explaining the nature of consumer society in this new British colony.     

High‐boron and High‐alumina Middle Byzantine (10th–12th Century ce) Glass Bracelets: A Western Anatolian Glass Industry

The trace element boron is present in most ancient glasses as an impurity, and high boron (≥ 300 ppm) marks raw material sources that are geologically specific and relatively uncommon. Recent analyses of Byzantine glass with high boron contents suggest that glass‐making was not limited to the traditional regions of the Levant and Egypt, and a production origin in or near western Anatolia is proposed. Glass bracelets from ?i?n al‐Tīnāt in southern Turkey give fresh evidence for the production and circulation of high‐boron glasses that closely correlates with object typology. The patterning of findspots suggests that high‐boron glass was closely connected to the Byzantine world.     

Problems of Analysis by FTIR of Calcium Sulphate–Based Preparatory Layers: The Case of a Group of 16th‐Century Portuguese Paintings

This paper provides a contribution to FTIR analysis of calcium sulphate‐based grounds of paintings when a mixture of compounds with different degrees of hydration is present. The study is based on the analysis with that technique, electron microscopy coupled with energy‐dispersive X‐ray spectrometry and X‐ray diffraction of both the grounds of 16th‐century Portuguese paintings and reference samples prepared with anhydrite and calcium sulphate dihydrate bound in an animal glue solution. It is shown that the interpretation of the degree of hydration of calcium sulphate ground samples using FTIR cannot be based solely on the study of the hydroxyl bands, as is usual in routine work, but that small deviations of the S–O vibration bands are an important indicator of the presence of anhydrite in the grounds.     

Constructing national identity in Canada's capital, 1900–2000: Confederation Square and the National War Memorial

Ottawa's Confederation Square was initially planned to be a civic plaza to balance the nearby federal presence of Parliament Hill. A century of federal planning, with the direct involvement of Prime Minister W.L. Mackenzie King, repositioned it as a national space in the City Beautiful style. Recent renovations have improved its pedestrian amenity and restored much of the original plan by French urban designer Jacques Gréber. The square contains the National War Memorial and the National Arts Centre, yet is a weak public space due to weak edge definition, animation, and spatial enclosure. The war memorial design was selected in a 1925 international competition won by Britain's Vernon March. The Great War monument was not installed until the 1939 Royal visit, and Mackenzie King intended that the re-planning of the capital would be the World War II memorial. However, the symbolic meaning of the Great War monument gradually expanded to become the place of remembrance for all Canadian war sacrifices. The National War Memorial is more successful as a symbolic object than Confederation Square is as a public space, yet both have evolved into important elements of the Canadian capital's national identity.
