Seventeenth-Century Glass Trade Beads from La Salle's Fort St. Louis and the Grand Village of the Kaskaskia

Abstract

Glass trade beads are described here from two seventeenth-century sites located in the upper Illinois Valley, La Salle's 1682–1691 Fort St. Louis and the nearby Grand Village of the Kaskaskia, destroyed during an Iroquois raid in 1680. Simple monochrome drawn beads characterize both bead assemblages and each contains significant percentages of very small (<2 mm) and small (2–4 mm) size beads. Dominant colors are blue, white, and black. Turquoise-blue beads were a staple of the French trade at this time in the Illinois Country, particularly in transactions involving La Salle and his successors based at Fort St. Louis. Comparative treatment provided as part of this research indicates that there are significant similarities between the bead assemblage from Fort St. Louis and the beads recovered from the 1686 wreck of La Salle's ship Belle in Matagorda Bay off the Texas coast.     

Element localization in archaeological bone using synchrotron radiation X-ray fluorescence: identification of biogenic uptake

Trace element analysis related to archaeological bone is viewed as one way to determine levels of element exposure in past populations. This area of research is complex because there is the potential for the incorporation of trace elements from the burial environment into archaeological bone. We tested the hypothesis that matching the spatial distribution of trace elements within cortical bone with the biological structures would provide evidence of biogenic uptake. We examined samples from a non-segregated Royal British Naval cemetery (1793–1822) in Antigua, West Indies. A key historical question related to this population was the extent of exposure to lead and the resulting health effects. Images from conventional light microscopy (histological) analysis of the bone samples were matched with elemental maps of calcium, strontium, and lead that were created through the use of synchrotron radiation X-ray fluorescence (SR-XRF). Biogenic uptake of both strontium and lead was indicated based on the localization of these trace elements within discreet microstructural elements. The successful integration of histological information with XRF data is a powerful technique for the interpretation of past biological events through trace elements.     

Conspiracy theories in Republican Italy: the Pellegrino Report to the Parliamentary Commission on Terrorism

This article analyses the draft of the final report prepared by Senator Giovanni Pellegrino, who from 1994 to 2001 chaired the ‘Parliamentary Commission of Inquiry on terrorism in Italy and on the causes of the failure to identify those responsible for the massacres’. The document was completed in 1995 and attempted a general interpretation of the causes of the political violence that had been a major feature of the history of the Italian Republic up to that point. The report was closely connected with what is often described as the moment of the transition between Italy's ‘first’ and ‘second’ Republic and, in keeping with revisionist theories current at the time, attributed responsibility for misdeeds and occult plots (real or imagined) that occurred in Italy over a period of forty years primarily to ideological division caused by the Cold War. This paper argues that this resulted in a highly distorted narrative of Italian history in which events appear to be determined almost exclusively by external factors to the exclusion of important internal dynamics.     

Lead concentrations in bones and soil

Lead concentrations were measured in 41 rib samples from the Romano-British cemetery at Poundbury and in two sets of soil samples from the graves yielding up the bones. The levels of lead in the soil were in no way exceptional (means for the two series were 16·7 and 24·8 μg/g dry weight) and there was no correlation between soil lead and bone lead concentrations.Since bone lead concentrations vary independently of those in the soil, it is unlikely that the bones are contaminated by lead in the soil, at least under the conditions prevailing at this particular site.     

Chemical and lead isotope analysis of some lead-barium glass wares from the Warring States Period,unearthed from Chu tombs in Changde City,Hunan Province,China

In the context of the present study, we have conducted chemical and lead isotope analyses on twelve ancient glass samples unearthed from Chu tombs in Changde City, Hunan Province. The results of the chemical analysis of these samples show that all samples are PbO–BaO–SiO₂ glasses, thus indicating that they are all traditional ancient Chinese glasses. The chemical results also suggest that all Bi wares may either share a common source or were produced according to similar recipes. In turn, the eye beads are different from the Bi wares for their distinct chemical composition. The chemical results indicate that silica, lead-bearing material, barium-bearing material, and sodium/lime-bearing material are the main independent components of the raw materials employed in the production of these glass wares.     

Supply routes and the consumption of glass in first millennium CE Butrint (Albania)

Archaeological, historical and analytical evidence can identify trade patterns and the movement of people and products and thus reveal the cultural and economic connections that existed at a given time. In the case of first millennium CE glass, the manufacture of raw glass in a limited number of glass making installations with unique compositional characteristics makes it possible to trace the likely origin of the raw materials at consumption sites. In this way the analytical characterisation of a large corpus of glass finds can identify changes in the supply routes of high-end industrial products from the Roman to the middle Byzantine period.     

A cost surface model of volcanic glass quarrying and exchange in Hawai‘i

The spatial distribution of artifacts from the Pu‘u Wa‘awa‘a volcanic glass source (North Kona District, Hawai‘i Island) shows a pattern of direct access by those living in the immediately vicinity of the source with subsequent down-the-line exchange. Most quarrying and exchanges likely occurred within a single day’s travel from sites where artifacts were deposited. The exception to this is the discovery of non-local direct access evident in assemblages from the extreme southern end of Hawai‘i Island; these visits may have involved voyages by canoe. While people did not often travel far for volcanic glass they nonetheless appear to have had unfettered accessed to source material and freely conducted inter-community exchanges. This implies volcanic glass was treated as a common pooled resource and the existence of informal exchange relationships.     

Sasanian glass from Veh Ardašīr investigated by strontium and neodymium isotopic analysis

A collection of 31 glass fragments, dated to the 3rd to 7th century AD and excavated in Veh Ardašīr, (modern Iraq), were analysed for their Sr and Nd isotopic compositions with the aim of deepening our knowledge on glass circulating within central Mesopotamia during Sasanian times and to highlight the merits of isotope ratios for the definition of the production scenery. Based on the elemental composition of the samples, two groups related to the exploitation of different plant ashes were previously distinguished, and also a change in the silica source in the course of the 4th century AD emerged. The determination of isotopic distributions of Sr and Nd offers a deeper insight. The ⁸⁷Sr/⁸⁶Sr isotope ratio, together with the Sr elemental concentration, confirms this use of different plant ashes, and permits one to distinguish distinct glass batches, although the isotopic Sr signature does not allow us to highlight evidences of different provenances for the samples of different composition. Moreover, the ¹⁴³Nd/¹⁴⁴Nd isotope ratio suggests the use of sands belonging to a common geological area, and also allows the identification of a set of samples that were possibly produced exploiting a further different sand source. As a whole, Sr and Nd isotope ratio values for the samples considered, i.e. ⁸⁷Sr/⁸⁶Sr = 0.70833 to 0.70916 and ?Nd = −8.69 to −4.98, differ from the published isotopic data on middle Eastern glass samples and can therefore define a characteristic Sr–Nd signature for plant-ash Sasanian glass excavated in Veh Ardašīr.     

Glass from the Archaeological Museum of Adria (North-East Italy): new insights into Early Roman production technologies

In the present study, the first archaeometric data on an ample selection of intentionally coloured (or decoloured) Early Roman glass (1st–2nd centuries AD) from the Archaeological Museum of Adria (Rovigo, Italy) are reported. The analysed samples are 61 in total, both transparent and opaque, and were characterised from the textural (SEM-EDS), mineralogical (XRPD) and chemical (XRF, EPMA, LA-ICP-MS) points of view. This combined approach allowed us to identify the raw materials and production technologies employed in the manufacture of glassware. Results for the transparent samples show that they are all silica-soda-lime glasses. Most of them, independently of colour, have compositions close to those of typical Roman glass, produced with natron as flux. No relationships were identified among chemical compositions, types or production techniques, but a dependence on bulk composition was identified for some particular colours, revealing the careful and intentional selection of raw materials. This is the case of Sb-colourless glass, produced with sand of high purity, a group of intensely coloured objects, mainly emerald green and black, produced with soda ash as flux, and some blue examples produced with various sources of sand or soda ash as flux. Two main types of opacifiers were identified for the opaque samples: calcium antimonate for white, mauve and blue glasses, and lead antimonate for the yellow ones; in one case, a yellow lead-tin antimonate was also identified. As regards the opaque glasses, most of the samples opacified with calcium antimonate are silica-soda-lime in composition, similar to the typical Roman glass. Instead, samples opacified with lead and/or lead-tin antimonates are lead glasses, suggesting different production technologies.     

A Late 17th‐Century Trade Cargo from Ponta do Leme Velho,Sal Island,Cape Verde

In 1973, while recovering copper cargo from a 20th‐century ship wrecked off the Ponta do Leme Velho on the south‐east side of Sal Island, Cape Verde, explosives revealed an earlier ship cargo with dozens of Portuguese faience plates and bowls, glass beads and metal objects, including buckles, ammunition and copper manillas. The assemblage, including the ceramics and a marked silver tastevin, provide a site date between 1680 and 1700. The research presented here is a result of collaboration between CPAS and the authors in 2008 to analyse this assemblage in the context of late 17th‐century maritime trade.
