Interpreting the expansion of sea fishing in medieval Europe using stable isotope analysis of archaeological cod bones

Archaeological fish bones reveal increases in marine fish utilisation in Northern and Western Europe beginning in the 10th and 11th centuries AD. We use stable isotope signatures from 300 archaeological cod (Gadus morhua) bones to determine whether this sea fishing revolution resulted from increased local fishing or the introduction of preserved fish transported from distant waters such as Arctic Norway, Iceland and/or the Northern Isles of Scotland (Orkney and Shetland). Results from 12 settlements in England and Flanders (Belgium) indicate that catches were initially local. Between the 9th and 12th centuries most bones represented fish from the southern North Sea. Conversely, by the 13th to 14th centuries demand was increasingly met through long distance transport – signalling the onset of the globalisation of commercial fisheries and suggesting that cities such as London quickly outgrew the capacity of local fish supplies.     

Troubadours in Debate: The Breviari d'Amor

Matfre Ermengaud's thirteenth-century Occitan encyclopedia, the Breviari d'Amor, concludes with a treatise on courtly love, the “Perilhos tractat d'amor de donas segon que han tractat li antic trobador en lors cansos.” In this treatise, the chief figures of courtly love—the lovers, ladies, troubadours, and maldizen, with Matfre as narrator and participant—dispute key tenets of love, quoting frequently from numerous troubadour lyrics in order to prove their arguments. In fact, the “Perilhos tractat” presents quotations of troubadour lyric in a disputative manner so as to highlight the troubadours as themselves in debate, although the Breviari purports to be structured by the overarching principle of love dictated by the visual mnemonic metaphor of the Tree of Love. This study examines the quotations of the troubadour lyrics here as dialectical, then, rather than as expressing and confirming a unitary vision of Natural Love. The “Perilhos tractat” is a debate not simply on love but also on the understanding and reception of the troubadours more broadly; that is, Matfre's dialectical use of troubadour lyric generates a broader debate about the meaning of the troubadours’ lyrics and their poetic legacy in the late thirteenth century.     

Birdmen, cemís and duhos: material studies and AMS C dating of Pre-Hispanic Caribbean wood sculptures in the British Museum

This paper presents 19 AMS radiocarbon dates from nine pre-Hispanic Caribbean (Taíno/Lucayan) wooden sculptures in the British Museum collections, provenanced to Jamaica, Hispaniola and the Bahamas. Together with strontium isotope results and wood and resin identifications, these data build a material and chronological context for some of the most recognised examples of Taíno art – from duhos (ceremonial seats) and cemís (free standing depictions of deities, ancestors and spirits) to canopied stands used to hold hallucinogenic drugs during the cohoba ceremony. Each sculpture widens our understanding of Caribbean carving traditions, stylistic variation, chronologies and material resource utilisation. A group of three sculptures recovered from Carpenters Mountains, Jamaica, carved by AD 1300 and brought together as a ceremonial ‘set’, each appear to have had their inlays renewed over a century later, suggesting long-term use. Three key examples of the main Caribbean duho categories (high-back, low-back and extended), provide insights into the diversity of styles present in the region post-AD 1100. The British Museum's corpus enables an exploration of regional styles, and potentially the work of individual artists.     

Palynological study of a Mi'kmaw shell midden,Northeast Nova Scotia,Canada

Before now, no palynological studies were made on shell midden deposits in Nova Scotia, despite a long history of archaeological research. A test study of samples taken from the shell midden at Maligomish (Indian Island) on the Northumberland Strait was conducted to determine if sufficient pollen, fern and moss spores, and other non-pollen palynomorphs (NPP's, including fungal remains, algal spores) could be recovered to allow interpretation of environmental conditions at the time of deposition. Several pollen processing methods were tested: sieving and swirling, chemical treatment with cold HCl, 5% KOH and brief exposure to 5% NH₄OH, and treatment with acetolysis solution. We recovered variable amounts of pollen, spores and NPP's from samples taken at 3–5 cm, 5–15 cm and 15–25 cm below surface. Abundant microcharcoal fragments prevented effective use of the swirling technique, but sufficient palynomorphs were recovered by chemical treatments to allow assessment of down-section changes in assemblages. Three radiocarbon ages from Mya arenaria and Crassostrea sp., and measurements of sediment grain size, moisture, organic and inorganic carbon, provide a framework for analysing palynological assemblage changes and context for interpreting differential palynomorph preservation. Despite some oxidation and microbial degradation of palynomorphs in the time interval (ca. 380–1600 cal yr BP), the midden assemblages correlate with pollen zones from marine and lake core sites within ca. 50 km of Maligomish. Shifts in abundances of algal spores, testate amoebae and aquatic plant pollen also indicate changes in depositional conditions during the time of midden use. The study provides the first reference for archaeologists attempting to use palynology for analysis of samples from Nova Scotian shell-bearing contexts.     

The Australian Historic Shipwreck Preservation Project: In situ Preservation and Long-Term Monitoring of the Clarence (1850) and James Matthews (1841) Shipwreck Sites

Increasingly, archaeologists are opting for on-site examination, reinterment, and in situ preservation of underwater cultural heritage sites as the first option in the management of sites at risk, as opposed to the more traditional excavation, recovery, conservation, and display/storage methods. This decision will inevitably be based on significance assessment, degree of perceived risk, and resourcing issues. However, long-term monitoring must become an integral part of these management programmes in order to quantitatively evaluate the effectiveness of the in situ preservation techniques employed. In 2012 the Australian Historic Shipwreck Preservation Project (AHSPP) was awarded a large Australian Research Council (ARC) Linkage Grant, enabling ten partner organizations and three Australian universities to collaborate in one of the largest multi-organizational maritime archaeology projects to be undertaken in Australia to date. One of the major aims of the project is to develop a protocol for the excavation, detailed recording and reburial of significant shipwrecks under threat, fostering a strategic national approach for the management of underwater cultural heritage (UCH) sites at risk. Two historically significant shipwreck sites that are considered under threat were chosen for this longitudinal comparative study — the Clarence (1850) located in Port Phillip Bay, Victoria; and the James Matthews (1841) which lies in Cockburn Sound, Western Australia. Both sites have been preserved in situ using two very different but innovative remediation strategies. More importantly, long-term monitoring programmes have been implemented on both sites, which will characterize changes in the reburial environment and the effect on the reinterred materials. In this way, the efficacy of both in situ preservation techniques will be systematically tested, providing a comparative analysis of practical protocols for the long-term protection and management of underwater cultural heritage.     

Regional Wage Rigidity: The European Union and United States Compared

In recent years it has been pointed out that regional unemployment disparities are much more entrenched across member states of the European Union (E.U.) than they are in the U.S. A 'conventional wisdom' has emerged to the effect that this difference is due in part to the greater degree of wage rigidity in E.U. regions. In this paper we explore this issue by estimating short run and long run real wage (in)flexibility for the regions in five core E.U. countries (Germany, France, Italy, the United Kingdom, and the Netherlands) and for the U.S. states for the period 1976–1994. We find that real wage (in)flexibility varies across regions both in the E.U. and the U.S., but that, on average, regional wages are no less flexible in E.U. core regions than in U.S. states. The paper also examines some of the possible correlates ofregional variations in wage (in)flexibility.
