Rethinking Jagiełło Hungary (1490–1526)

Abstract

Historians of the Commonwealth of Poland-Lithuania have identified the Sejm (Diet) of 1712–13 as a moment when, after the chaos of the Great Northern War, orderly government might have been restored and some political reforms enacted. Specifically, the efforts of August II to persuade the Sejm to pass wide-ranging fiscal and military reforms have been examined by Józef Gierowski, who argued that August II missed an opportunity at this Sejm to cement an alliance with the envoys (pos?owie) that might have curbed the powers of the hetmans, and gone on to enact further political reforms.

This focus on the king’s agenda, however, overlooks the reform programme pursued independently by the Sejm envoys. The envoys were hostile to the hetmans, but sought different reforms from the king. Examining their agenda allows a fuller understanding of this Sejm, as well as broadening our understanding of szlachta political thought more generally.     

A SIMPLE FIELD KIT FOR IDENTIFYING C4 PLANTS*

We have developed a simple field kit for identifying C₄ plants, the use of which requires little technical training. The system has proven very useful for surveying plants in areas for which carbon isotopic dating and dietary studies are to be undertaken.     

ON ISOTOPES AND OLD BONES*

This review charts the developments and progress made in the application of stable light isotope tools to palaeodietary adaptations from the 1970s onwards. It begins with an outline of the main principles governing the distribution of stable light isotopes in foodwebs and the quality control issues specific to the calcified tissues used in these analyses, and then proceeds to describe the historical landmark studies that have marked major progress, either in their archaeological applications or in enhancing our understanding of the tools. They include the adoption of maize agriculture, marine‐focused diets amongst coastal hunter–gatherers, trophic level amongst Glacial‐period modern humans and Neanderthals, and the use of savannah resources by early hominins in Africa. Particular attention is given to the progress made in addressing the challenges that have arisen out of these studies, including issues related to the routing of dietary nutrients. I conclude with some firm, and some more speculative, pointers about where the field may be heading in the next decade or so.     

NUCLEAR MAGNETIC RESONANCE SPECTROSCOPIC AND ISOTOPIC ANALYSIS OF CARBONIZED RESIDUES FROM SUBARCTIC CANADIAN PREHISTORIC POTTERY

Late prehistoric pottery is found in abundance at archaeological sites around Southern Indian Lake. Black residues, found on the two dominant vessel forms, flat plates and round pots, are presumed to be the remains of prehistoric meals. ¹³C cross-polarization magic-angle-spinning nuclear magnetic resonance spectroscopy (CPMAS NMR) and¹³C and¹⁵ N isotopic ratios and C/N ratios are used to reconstruct prehistoric diet and to shed light on possible uses for the plates. Samples of foods were cooked in clay pots, on a wood fire, to simulate the conditions of burning that could have produced the residue. Decomposition of carbohydrates, protein, and fat during cooking is studied with ¹³C CPMAS NMR, and the effect of cooking on isotopic and C/N ratios documented. Predominantly fish and fat were cooked in the pots, whereas the residues from plates contain a greater proportion of fat and could have been used as frying pans or possibly as fat-burning lamps placed on the ashes of a wood fire.     

An Experimental Approach to the Disaggregation of Samples from Peat Deposits

Abstract

Excavations carried out at Dudley Castle recovered an assemblage of animal bones dominated by horse from the vaulted cellar beneath the Great Hall. The deposit dates to c. 1710 and appears to have been the result of partial butchery of several aged horses. The possible interpretations are discussed and it seems likely that the deposit represents the leftover waste of a knacker.     

STABLE CARBON ISOTOPE MEASUREMENTS OF THE CARBOXYL CARBONS IN BONE COLLAGEN*

In order to explore the possibility that intramolecular differences in the δ¹³C value of bone collagen can provide useful infomation for isotopic dietary analysis, a method for reliably measuring the δ¹³C value of the peptide-bonded carboxyl carbons in collagen was developed and applied to a wide range of modem and ancient species, including humans. Carboxyl carbons were selectively removed as CO₂ by decarboxylation of collagen hydrolysates with ninhydrin (2,2-dihydroxy-l,3-indanedione). Carboxyl carbons were usually isotopically heavier than the total carbon in the collagen, with differences ranging from -0.9 to 4.0%c. Animals at higher trophic levels and with more positive δ¹⁵N values usually had smaller differences than the lower animals while humans had the largest range, reflecting their larger range of diets.
