Microbial ecology has been recognized as useful in archaeological studies. At Archaic Monte Iato in Western Sicily, a native (indigenous) building was discovered. The objective of this study was the first examination of soil microbial communities related to this building. Soil samples were collected from archaeological layers at a ritual deposit (food waste disposal) in the main room and above the fireplace in the annex. Microbial soil characterization included abundance (cellular phospholipid fatty acids (PLFA), viable bacterial counts), activity (physiological profiles, enzyme activities of viable bacteria), diversity, and community structure (bacterial and fungal Illumina amplicon sequencing, identification of viable bacteria). PLFA-derived microbial abundance was lower in soils from the fireplace than in soils from the deposit; the opposite was observed with culturable bacteria. Microbial communities in soils from the fireplace had a higher ability to metabolize carboxylic and acetic acids, while those in soils from the deposit metabolized preferentially carbohydrates. The lower deposit layer was characterized by higher total microbial and bacterial abundance and bacterial richness and by a different carbohydrate metabolization profile compared to the upper deposit layer. Microbial community structures in the fireplace were similar and could be distinguished from those in the two deposit layers, which had different microbial communities. Our data confirmed our hypothesis that human consumption habits left traces on microbiota in the archaeological evidence; therefore, microbiological residues as part of the so-called ecofacts are, like artifacts, key indicators of consumer behavior in the past.Electronic supplementary materialThe online version of this article (doi:10.1007/s00248-016-0904-8) contains supplementary material, which is available to authorized users.

Microbial communities in human-impacted soils of ancient settlements have been proposed to be used as ecofacts (bioindicators) of different ancient anthropogenic activities. In this study, bacterial, archaeal and fungal communities inhabiting soil of three archaic layers, excavated at the archaeological site on Monte Iato (Sicily, Italy) and believed to have been created in a chronological order in archaic times in the context of periodic cultic feasts, were investigated in terms of (i) abundance (phospholipid fatty acid (PLFA) analysis and quantitative PCR)), (ii) carbon(C)-source consumption patterns (Biolog-Ecoplates) and (iii) diversity and community composition (Illumina amplicon sequencing). PLFA analyses demonstrated the existence of living bacteria and fungi in the soil samples of all three layers. The upper layer showed increased levels of organic C, which were not concomitant with an increment in the microbial abundance. In taxonomic terms, the results indicated that bacterial, archaeal and fungal communities were highly diverse, although differences in richness or diversity among the three layers were not detected for any of the communities. However, significantly different microbial C-source utilization patterns and structures of bacterial, archaeal and fungal communities in the three layers confirmed that changing features of soil microbial communities reflect different past human activities.

In this paper we investigate local foodways and ritual consumption in Iron Age Sicily through a study of cooking pots, integrating contextual, archaeozoological, archaeobotanical and chemical data. We focus on material from the central cult site of the settlement of Monte Iato, located in the hinterland of western Sicily, in order to explore the interaction between food, people, bio-/artefacts and environments as a process of formulating and reformulating social relationships and local power dynamics within specific social spaces and settings. We reveal different foodways and consumption practices within the same cult site, characterized on the one hand by long-standing traditions, with more or less constant and unchanging dishes, and on the other by the integration of external stimuli. We discuss the emergence of foreign- (Greek/Phoenician-) style cooking pots and ingredients as markers of an haute cuisine, developed with the aim of social differentiation.

This paper, jointly written by participants of a workshop held in 2021, argues for an increased recognition and application of neutron activation analysis (NAA) in the archaeology of the ancient Mediterranean. Discussing the methodological strengths and challenges, it highlights the great potential NAA has for collecting proxy data from ceramics in order to develop progressive concepts of archaeological research within and beyond the Mediterranean Bronze and Iron Age, pointing out opportunities to revisit long-held assumptions of scholarship and to refine visual/macroscopic provenance determinations of pottery. To take full advantage of NAA’s strengths toward a better understanding of the socioeconomic background of ceramics production, distribution, and consumption, the paper emphasises the need for both interdisciplinary collaboration and basic data publication requirements.

The study focuses on the reconstruction of the chaîne opératoires of Iron Age pottery production at Monte Iato (Sicily, southern Italy), in terms of clay deposits selection, raw material processing and firing technology. A set of 76 specimens from the central cult place of the site (600-450 BCE) and belonging to functional categories of serving and consumption of food and drinks, food preparation, cooking and storage were analyzed using macroscopic, mineralogic and petrographic methods. As proxy data, the results deepen our insights into local potters’ technologies and choices by revealing varied and multi-layered communities of practice determined by corresponding ceramic manufacture processes. These do differ in regards of raw material procurement, clay processing as well as firing techniques but at the same time are in some extent linked together through the constant use of grog as temper – a practice detectable over the entire use of the cult site of over 100 years.
