In 1920 on the island of Lolland, in southern Denmark the remains of one of northern Europe’s richest graves came to light, the Hoby chieftain burial. It revealed a large number of luxurious Roman goods, including two silver drinking cups decorated with Greek-inspired scenes from Homer’s Iliad. The burial dates to the beginning of the Roman Iron Age (1CE -200CE), and represents a key point in time when the Roman Empire failed to expand towards the north and changed its strategy towards a more political and diplomatic type of relationship with northern Europe. Hence, the Hoby burial is considered to be a key example of this type of relationship. We revisited the burial and present the first strontium isotope analyses of the human remains of the Hoby individual from three of his teeth and 10 additional environmental samples to shed light on his provenance. We discussed these results in light of the new insights provided by recent excavations of a contemporary nearby settlement. Our results indicate that the Hoby individual was most probably of local origin, corroborating previous interpretations. Furthermore, the associated settlement seems to confirm the central role of Hoby in the Early Roman Iron Age society.

This paper focuses on the material study (radiocarbon dating, wood identification and strontium isotope analyses) of four large ‘India occidentali’ clubs, part of the founding collections of the Ashmolean Museum, in Oxford, and originally part of John Tradescant’s ‘Ark’, in Lambeth (1656). During the seventeenth century, the term ‘India occidentali/occidentales’ referred not only to the ‘West Indies’ (its literal translation), but to the Americas as a whole; hence, the Ashmolean clubs and, indeed, thecforty examples of similarly large, decorated clubs known in international museum collections had no firm provenance and lacked even the most basic information. Previous attempts at attribution, based on stylistic comparisons with nineteenth- to twentieth-century Brazilian and Guyanese clubs, have proved inconclusive given the unique features of this club style, raising the intriguing possibility that these may be exceptionally rare examples of ‘Island Carib’ (Kalinago) material culture, particularly as images of such clubs appear in seventeenth-century ethnographic accounts from the Lesser Antilles. This paper provides new data for these poorly known objects from early collections, revealing not only the type of wood from which they were carved (Platymisciumsp. andBrosimumcfguianense) and their probable dates of manufacture (c AD1300–1640), but also their possible provenance (strontium results are consistent with a possible range from Trinidad south to French Guiana).

Abstract A commercial fishery targeting the anadromous Bering cisco (Coregonus laurettae) is occurring in the Yukon River, Alaska, USA. All three of the known global spawning populations occur in Alaska. Managers believed that two of the three populations were being harvested in the fishery. To determine the likelihood of a mixed-stock fishery, we used 87Sr/86Sr values from the freshwater region of otoliths, from spawning adult Bering cisco of known origin (n = 82), to create a baseline. A 10-fold cross-validated, quadratic discriminant function analysis (DFA) of the three baseline population 87Sr/86Sr values (Yukon River, n = 27; South Fork Kuskokwim River [Kuskokwim River], n = 25; and Susitna River, n = 30) correctly reclassified 98.8% of the fish analysed. The baseline DFA model was then used to classify the 87Sr/86Sr values from a set of otoliths removed from commercially harvested Bering cisco (n = 139). Using a posterior probability threshold of 90%, we found that >97% of the commercial samples were classified as originating in the Yukon River. The remainder of the commercial samples were classified as originating in the Kuskokwim River (0.7%) or from the Susitna River (1.5%). The presence of 87Sr/86Sr values consistent with the Susitna River discovered in the Yukon River baseline (n = 1) and commercial samples (n = 2) suggested either multiple isotope signatures within the Yukon River population or straying among populations. Strontium isotope data provide an effective tool to monitor the movements and stock composition of Bering cisco.
