Secrets of the Spearhead : Developing Continuum Mechanical Simulations and Organic Residue Analysis for the Study of Scandinavian Flint Spearhead Functionality

Lundström, Fredrik January 2019 (has links)
This thesis is a pilot study, designed to test and develop methods suitable for the study of Scandinavian flint spearhead functionality. The functionality of projectile and lithic point armament has not been studied for almost 30 years in Scandinavia. Meanwhile, methods used to analyse lithic projectiles have developed considerably. However, few of these methods are precise enough to be used in conjunction with Scandinavian stone technological analyses that emphasize the societal aspect of lithic points. Consequently, two methods were chosen that could provide data for Scandinavian research issues: 3D-scanning/continuum mechanical simulations and organic residue analysis. The methods were tested on 6 experimental spearheads. The continuum mechanical simulation generated both visual and numerical data that could be used to create precise functional-morphological descriptions. The data could also potentially be used for projectile point classification. The organic residue analysis revealed promising results for the use of an artefact and activity specific analysis, with a sequential extraction protocol. In unison, the results from both analyses could be used to reveal how spearheads were functionally designed and used in Stone Age Scandinavia, even though there are methodological and technological issues that need solving.

Molecular and isotopic demonstration of the processing of aquatic products in northern European prehistoric pottery.

Heron, Carl P., Anderson, E., Craig, Ollie E., Forster, S. H., Stern, Ben 06 July 2009 (has links)
A number of charred surface residues, adhering to ceramic containers, were obtained from various coastal and inland sites in north-west Europe dating from the sixth to the fourth millennium cal bc. In order to investigate the use of these vessels and in particular to identify any marine products, the residues were subjected to carbon and nitrogen stable isotope analysis. Variation in carbon isotope ratios between different samples indicated that some vessels may have been used to process marine products. This analysis was corroborated by specific identification of aquatic products following structural and isotopic characterization of lipids extracted from selected samples.

Organic residue analysis of Egyptian votive mummies and their research potential

Brettell, Rhea C., Martin, William H.C., Atherton-Woolham, S., Stern, Ben, McKnight, L. 15 June 2016 (has links)
Yes / Vast numbers of votive mummies were produced in Egypt during the Late Pharaonic, Ptolemaic, and Roman periods. Although millions remain in situ, many were removed and have ultimately entered museum collections around the world. There they have often languished as uncomfortable reminders of antiquarian practices with little information available to enhance their value as artefacts worthy of conservation or display. A multi-disciplinary research project, based at the University of Manchester, is currently redressing these issues. One recent aspect of this work has been the characterization of natural products employed in the mummification of votive bundles. Using gas chromatography–mass spectrometry and the well-established biomarker approach, analysis of 24 samples from 17 mummy bundles has demonstrated the presence of oils/fats, natural waxes, petroleum products, resinous exudates, and essential oils. These results confirm the range of organic materials employed in embalming and augment our understanding of the treatment of votives. In this first systematic initiative of its kind, initial findings point to possible trends in body treatment practices in relation to chronology, geography, and changes in ideology which will be investigated as the study progresses. Detailed knowledge of the substances used on individual bundles has also served to enhance their value as display items and aid in their conservation. / RCB is supported by a PhD studentship from the Art and Humanities Research Council (43019R00209).

Organic residue analysis of Early Neolithic 'bog pots' from Denmark demonstrates the processing of wild and domestic foodstuffs

Robson, H.K., Saul, H., Steele, Valerie J., Meadows, J., Nielsen, P.O., Fischer, A., Heron, Carl P., Craig, O.E. 16 February 2021 (has links)
Yes / Ceramic containers, intentionally deposited into wetlands, offer detailed insights into Early Neolithic culinary practices. Additionally, they are key for ascertaining the Neolithisation process in Denmark since they appear to form a typo-chronological sequence. Here, we use a combination of organic residue analysis (ORA) of pottery alongside Bayesian chronological modelling of the radiocarbon dates obtained on these vessels to explore the initial stages of votive deposition in wetlands, a practice that stretches from the Mesolithic to the onset of Christianity in Northern Europe. We consider 34 Early-Middle Neolithic (c. 3900–2350 cal BC) ‘bog pots’ from Denmark, of which 20 have ORA data, and 26 have been dated directly. Carbonised surface residues and absorbed lipids from powdered sherds were analysed using a combination of bulk carbon and nitrogen stable isotope analysis, gas chromatography-mass spectrometry (GC–MS) and GC-combustion-isotope ratio MS (GC-C-IRMS). The molecular and isotopic compositions of the analysed samples revealed the presence of aquatic, ruminant carcass and dairy fats as well as plant waxes with the majority containing mixtures thereof. Dairy fats were present from the onset of the Funnel Beaker culture, whilst aquatic foods, prevalent at the close of the preceding Mesolithic period, continued to be processed in pottery for the following thousand years. / UK Arts and Humanities Research Board Grant B/RG/AN1717/APN14658 (to O.E.C.) and the UK Arts and Humanities Research Council Grant AH/E008232/1 (to C.P.H and O.E.C.) for funding this research.

Beyond the vessel: Organic residue analysis of Late Bronze and Early Iron Age south-east European pottery

Bastos, Beatriz I.F. de January 2019 (has links)
The Encounters and Transformations in Iron Age Europe project (ENTRANS) aims to expand our knowledge regarding the nature and impact of cultural encounters during the European Iron Age. The study of ceramic vessels was included in the project, in order to further understand cultural practices in the south-east Alpine region. Organic residue analysis is an important tool in archaeological research for determining the presence of food and other organic substances associated with ceramic vessels. It has the potential to significantly improve our understanding of Iron Age societies and the interactions between them. This research focuses on the analysis of visible and absorbed organic residues from 377 ceramic vessels, from Late Bronze Age and Early Iron Age sites in Slovenia and Croatia, by gas-chromatography mass spectrometry. Two methods of lipid extraction were compared in a pilot study compressing 30 potsherds from Kaptol (solvent vs. acid extraction). This study revealed that more information was obtained by acid extraction, thus it was selected as the main method of extraction for this project. Differences between settlement, funerary and ritual sites were observed, suggesting that the vessels placed in the graves were not previously used or carried foodstuff with low lipid content, such as liquids and dry foods/cereals. Some types of residues were only identified in funerary vessels, specifically potential castor oil in Kaptol, mixed with other fats and oils. Lipid biomarkers and lipid ratios revealed significant differences between contexts and different sites, suggesting that the differences in cultural practices can also be identified in the use of ceramic vessels. Some residues were also sampled for gas-chromatography compound-specific isotope ratio mass spectrometry and bulk isotope analysis (only visible residues), which identified potential dairy fats in two potsherds from Poštela. The results were also compared with the contextual information, mainly the faunal remains, and the data obtained from the osteology and diet study preformed with individuals from the same area and chronology as the ceramic vessels. / Encounters and Transformations in Iron Age Europe Project (ENTRANS); Humanities in the European Research Area (HERA); Institute Life Sciences Research (ILSR) University of Bradford.

La ceramica comune dall’alto al basso medioevo in Veneto (Italia) : tipologie, commerci e analisi sui residui organici / Coarse and cooking ware from early medieval to the Middle ages in Veneto (Italy) : topology, commerce and organic compounds / La céramique commune du haut au bas Moyen-âge en Veneto (Italie) : typologies, commerces et résidus organiques

Ganzarolli, Giovanna 15 December 2017 (has links)
Cette recherche doctorale porte sur l’analyse des « céramiques communes à pâte grossière » issues de 4 fouilles archéologiques de la Vénétie : celles de la cathédrale de Padoue, de Rocca de Monselice (Padoue), du château de Montagnone à Montegrotto Terme (Padoue) et de l’ancien cinéma Astra à Chioggia (Venise). Cette recherche se focalise plus particulièrement sur la « céramique commune à pâte grossière » employée pour l’usage culinaire à l’échelle de la Vénétie. Elle vise à mieux comprendre les changements de morphologies, de matières premières employées mais également de fonctionnalité entre le IVe et le XIV siècle apr. J.-C. Dans le cadre de ce travail, cette catégorie de céramique a été étudiée à travers une approche pluridisciplinaire associant, à la démarche d’archéologique et de typologique classique, des observations pétrographiques et des analyses chimiques de résidus organiques. La combinaison de ces expértises a permis d’observer :• une évolution typologique à l’échelle de la période chronologique investie pour la région de Padoue ces dernières ayant été confrontée avec des données déjà publiée pour la région de la Vénétie et des territoires limitrophes ;• des caractéristiques pétrographiques et un changement des « recettes » de pâtes employées dans la production de la céramique pour les usages culinaires ;• certains aspects fonctionnels des céramiques, notamment sur pour artefacts retrouvés lors de la fouille de la cathédrale de Padoue, permettant même de proposer des hypothèses sur les habitudes alimentaires ;• un lien entre l’évolution des « céramiques communes à pâte grossière » et les dynamiques économiques et politiques régionales. / The aim of this research is the study of cooking wares, founded in 4 archaeological sites of Veneto region (North-eastern Italy): the archaeological excavation near the Padua cathedral, the archaeological excavation of Rocca di Monselice Castle (PD); the archeological sites of Montagnone of Montegrotto Terme castle; and the excavation in the ex-cinema Astra in Chioggia (VE). Therefore the object of this research is to observe over long time (from 4th to 14/15th century) the cooking wares of a small territory of Veneto region, the central-eastern part, to understand the evolutional change of morphologies, the origins of raw materials and the pottery function.The pottery was studied with the exploitation of different techniques and methodologies: the archaeological and typological approach; the petrographical analysis and the organic residue analysis. This method allowed the observation of:$\begin{itemize}\item the pottery morphological evolution, over long time in a small territory, taking into account also the published ceramic datas of Veneto and the nearest regions;\item the petrographical characteristic and the different use of ceramic paste over a log term for the cooking wares;\item for the archaeological site of Padua cathedral, the functional aspect of pottery. This aspect permits to speculate on the diet habits;\item the link between the cooking and coarse wares and the historical and economical aspects of Veneto. \end{itemize}$Finally this research gives a database to better understand the production characteristics of Paduan cooking wares.

Ancient lipids reveal continuity in culinary practices across the transition to agriculture in Northern Europe

Craig, O.E., Steele, Valerie J., Fischer, Anders, Hartz, S., Andersen, S.H., Donohoe, P., Glykou, A., Saul, H., Jones, D.M., Koch, E., Heron, Carl P. January 2011 (has links)
Farming transformed societies globally. Yet, despite more than a century of research, there is little consensus on the speed or completeness of this fundamental change and, consequently, on its principal drivers. For Northern Europe, the debate has often centered on the rich archaeological record of the Western Baltic, but even here it is unclear how quickly or completely people abandoned wild terrestrial and marine resources after the introduction of domesticated plants and animals at approximately 4000 calibrated years B.C. Ceramic containers are found ubiquitously on these sites and contain remarkably well-preserved lipids derived from the original use of the vessel. Reconstructing culinary practices from this ceramic record can contribute to longstanding debates concerning the origins of farming. Here we present data on the molecular and isotopic characteristics of lipids extracted from 133 ceramic vessels and 100 carbonized surface residues dating to immediately before and after the first evidence of domesticated animals and plants in the Western Baltic. The presence of specific lipid biomarkers, notably omega-(o-alkylphenyl)alkanoic acids, and the isotopic composition of individual n-alkanoic acids clearly show that a significant proportion ( approximately 20%) of ceramic vessels with lipids preserved continued to be used for processing marine and freshwater resources across the transition to agriculture in this region. Although changes in pottery use are immediately evident, our data challenge the popular notions that economies were completely transformed with the arrival of farming and that Neolithic pottery was exclusively associated with produce from domesticated animals and plants.

The circulation and consumption of Red Lustrous Wheelmade Ware: petrographic, chemical and residue analysis

Knappett, C., Kilikoglou, V., Steele, Valerie J., Stern, Ben January 2005 (has links)
Yes / Red Lustrous Wheelmade ware is one of the most recognisable classes of pottery from the Late Bronze Age of the east Mediterranean. Yet both its production source and the nature of its contents and use remain a source of some debate. These questions are tackled here through an intensive programme of scientific analysis involving 95 samples of Red Lustrous Wheelmade ware and related wares from seven sites in Turkey, Cyprus and Egypt. Petrography and instrumental neutron activation analysis are combined in the study of the ceramic fabrics, with a view to specifying the source of this ware; while gas chromatography and gas chromatography-mass spectrometry are used to analyse absorbed and visible residues in and on the sherd samples, in the hope of shedding light on vessel contents and possible use. The results of the fabric analysis show the ware to be extremely homogeneous, indicative of a single source: northern Cyprus is at present the most likely candidate, although further analysis, particularly of clay samples from the region in question, would certainly be desirable. The residue analysis suggests that Red Lustrous Wheelmade ware might have been used to carry some kind of plant oils, possibly perfumed, and that in some instances the vessel interior was coated with beeswax as a sealant. / AHRC
