Biomolecular and isotopic characterisation of lipid residues absorbed in Impressed Wares from the Early Neolithic village of Skorba, Malta

Organic residue analysis (ORA) was used to characterise the lipid content of Impressed Ware vessels recovered from the Early Neolithic village of Skorba, Malta. ORA utilises both chromatographic and isotopic analytical techniques, and provides direct evidence for the function of ceramic vessels analysed. Lipid residues were interpreted against authentic reference fats of Mediterranean origin, and in light of the archaeological data available. The results showed that lipid yields were generally low, however direct evidence for the processing of an admixture comprising ruminant fat and marine oil was obtained in a vessel dated to the Early Neolithic period. This investigation also tests the feasibility of carrying out ORA on ceramic vessels recovered from Maltese archaeological contexts.peer-reviewe

Integrated novel applications for dietary reconstructions in Prehistory

A broad range of biogeochemical techniques encompassing a wide array of disciplines is successfully being used to address key questions in archaeological research, including chronology, migration, trade, palaeopathology and palaeoenvironmental reconstructions. The aim of the session was to focus particularly on the developments in palaeodietary studies, which inform about population dynamics and socio-cultural characteristics of different communities over space and time. Biogeochemical techniques in particular have shown a remarkable adeptness at acquiring data from a variety of archaeological substrates, such as ceramics, lithics, textiles, sediments, plant remains, and human and animal tissues, including dental calculus. These techniques allow an intensive exploitation of archaeological material, especially organics, which are often preserved in small quantities and would otherwise not have been considered viable for analysis. The success of this approach is attested by the wide range of publications detailing the development and application of novel techniques, targeted towards answering fundamental archaeological questions. This was also reflected in the broad range of analytical methodologies presented during the session, which comprised bulk light and heavy stable isotope analysis that allows a better understanding of the composition of ancient diets, characterization of foodstuffs absorbed within ceramic vessels using lipid residue analysis, identification of protein sequences informing on dietary deficiencies, studies on microbial communities associated with the production of specific food types, and microscopic techniques used on teeth and dental calculus to recover palaeodietary information

Phoenician maritime pioneering and Punic expansion : reconstructing trade and dietary patterns

Perhaps the most significant legacy attributed to the Phoenicians was their mastery of the seas, which led them to establish the first grand commercial Mediterranean network, expanding from Lebanon to beyond the Pillars of Hercules between the 8th and 6th centuries BC. The Punic culture, which flourished in the central and western Mediterranean from Phoenician colonies, maintained the exceptional navigation skills of the Phoenicians, but developed into more settled and structured territories that allowed the communities to intensify their exploitation of Mediterranean resources. Their rise to prominence can be measured by the threat they posed to the Roman Republic, while the salvage of the agronomic treatises by Mago after the sacking of Carthage attests to their renowned agrarian competence. The paucity of Phoenician and Punic written sources essentially means that material culture provides the data with which to model community lifeways, including daily dietary patterns, and trade more generally. The aim of this session was to bring together research focused on diet and trade in the Phoenician and Punic world, building on the work that has been done on foodways to model community interaction (Mata Parreño et al. 2010; Delgado and Ferrer 2011a and 2011b). The session comprised five oral contributions and a poster presentation. The focus was on central and western Mediterranean mainland regions and island territories. Findings from more recent archaeological excavations were described and discussed, and scientific applications to archaeological material were outlined and interpretations put forward and discussed.peer-reviewe

Molecular and isotopic investigations of pottery and “charred remains” from Sannai Maruyama and Sannai Maruyama No. 9, Aomori Prefecture.

This paper presents a preliminary study of the analysis of organic residues of Early and Middle Jomon pottery and ‘charred remains.’ Samples are taken from the Sannai Maruyama site and the Sannai Maruyama No. 9 site in Aomori City, Aomori Prefecture in northern Japan. The following questions are addressed in this study: (i) Do organic residues survive in association with pottery vessels and charred remains? (ii) Can the residues be identified based on molecular and isotopic criteria applied in other investigations? (iii) Are the residues associated with the charred remains common to the residues associated with the pottery vessels? (iv) How do these residues contribute to our understanding of food processing and consumption? Results of our analysis indicate that the lipid composition of the pottery extracts is remarkably similar although some of the sherds exhibited better preservation and a wider range of molecules were detected albeit in lower abundance. There is a marked contrast with the composition of the lipid extracts of the ‘charred remains.’ The lipid compositions of sample sets from Sannai Maruyama and Sannai Maruyama No. 9 suggest aquatic resources in the pottery but with a plant contribution. The ‘charred remains’ from Sannai Maruyama contain plant tissues most likely with a high starch composition such as nuts. Lipids were recovered from the majority of the samples

Regional asynchronicity in dairy production and processing in early farming communities of the northern Mediterranean

In the absence of any direct evidence, the relative importance of meat and dairy productions to Neolithic prehistoric Mediterranean communities has been extensively debated. Here, we combine lipid residue analysis of ceramic vessels with osteo-archaeological age-at-death analysis from 82 northern Mediterranean and Near Eastern sites dating from the seventh to fifth millennia BC to address this question. The findings show variable intensities in dairy and nondairy activities in the Mediterranean region with the slaughter profiles of domesticated ruminants mirroring the results of the organic residue analyses. The finding of milk residues in very early Neolithic pottery (seventh millennium BC) from both the east and west of the region contrasts with much lower intensities in sites of northern Greece, where pig bones are present in higher frequencies compared with other locations. In this region, the slaughter profiles of all domesticated ruminants suggest meat production predominated. Overall, it appears that milk or the by-products of milk was an important foodstuff, which may have contributed significantly to the spread of these cultural groups by providing a nourishing and sustainable product for early farming communities

Archaeometric evidence for the earliest exploitation of lignite from the bronze age Eastern Mediterranean

This paper presents the earliest evidence for the exploitation of lignite (brown coal) in Europe and sheds new light on the use of combustion fuel sources in the 2nd millennium BCE Eastern Mediterranean. We applied Thermal Desorption/Pyrolysis-Gas Chromatography-Mass Spectrometry and Polarizing Microscopy to the dental calculus of 67 individuals and we identified clear evidence for combustion markers embedded within this calculus. In contrast to the scant evidence for combustion markers within the calculus samples from Egypt, all other individuals show the inhalation of smoke from fires burning wood identified as Pinaceae, in addition to hardwood, such as oak and olive, and/ or dung. Importantly, individuals from the Palatial Period at the Mycenaean citadel of Tiryns and the Cretan harbour site of Chania also show the inhalation of fire-smoke from lignite, consistent with the chemical signature of sources in the northwestern Peloponnese and Western Crete respectively. This first evidence for lignite exploitation was likely connected to and at the same time enabled Late Bronze Age Aegean metal and pottery production, significantly by both male and female individuals
