Abstract: This paper proposes a Bayesian model for the 14C chronology of Sicilian Early and Middle Bronze Age, with a specific focus on the northeastern sector of the island. Building on the available 14C determinations, the model allows addressing a number of chronological questions left open in literature, making a first step towards an independent absolute chronology. The analysis put the start of the earlier part of Early Bronze Age (Capo Graziano 1-Casa Lopez phase) between 2400 and 2175 cal BC, and the end at about 1960 cal BC. The advanced stage of the same period (Capo Graziano 1-Filo Braccio phase) is likely to have started and ended around 1960 and 1730 cal BC respectively. The model indicates that the time slot with the highest posterior probability for the start of the Middle Bronze Age–Milazzese (Portella phase) is between 1490 and 1460 cal BC. This turns up to be earlier than held to date. Notably, the model enables for the first time to bracket the development of the later stage of Early Bronze (Capo Graziano 2-M. di Capo Graziano phase) between 1730 (end of Filo Braccio phase) and 1490/60 cal BC (start of Middle Bronze Age–Portella phase). The latter date is earlier than usually held for the end of Capo Graziano 2. The existence of a narrow gap between the end of the latter and the start of Middle Bronze Age-Portella phase is tentatively proposed only on stratigraphic grounds. Further, the analysis enables for the first time to pinpoint and quantify the lag that is likely to have existed between the start of those Sicilian prehistoric phases and the appearance of Late Helladic imports. The comparison with the Aegean 14C Bayesian chronology indicates that a time lag (about 45 yr) is likely to have occurred between the start of Capo Graziano 2 and of the Late Helladic period. A time lag between 20 and 70 yr is likely to have existed between the start of the Sicilian Middle Bronze Age and of the Late Helladic III. Arguments tentatively supporting the narrower interval are also discussed. [Copyright &y& Elsevier]

Abstract: The modelling of past settlement and landscape structure from incomplete evidence is a well-established archaeological agenda. This paper highlights a model of spatial interaction and settlement evolution that has long been popular in urban geography and which was first applied to model historical settlement hierarchies some twenty-five years ago, but whose use since then for archaeological purposes has been very limited. Via a case study from Bronze Age Crete, we extend the analytical range of this model by suggesting ways in which it can (a) remain effective in the presence of missing data, (b) be given a stronger grounding in the physical landscape, and/or (c) be used to consider the evolutionary trajectory of settlements and physical routes over time.

Abstract: This paper presents the results of an investigation of organic binding media detected in samples from the Mycenaean wall-paintings at the “Palace of Nestor” in Pylos (Western Messenia, Greece): samples dated from the Late Bronze Age (ca. 1200 BC). This is the first scientific study to be conducted on organic binding media in Mycenanean painting, and it is a study that aims to contribute significantly towards our understanding of the original painting techniques used during the Bronze Age. The analytical procedures employed for the detection and characterization of the organic substances preserved within the paint layers (proteinaceous materials, lipids and plant gums), were based on chromatography/mass spectrometry techniques (PY–GC/MS, GC/MS). The most significant results, highlighting an a secco painting technique, are herein reported and discussed. [Copyright &y& Elsevier]

Abstract: In recent years there has been a growing interest in Mycenaean glass among archaeologists and scientists. Scholars have traditionally thought that all Mycenaean glass was imported either in finished form or as ingots and simply shaped or worked at the Mycenaean sites. Chemical studies of other Mycenaean glass () support the hypothesis that glass was imported into Mycenaean Greece, but there is also indication for glass production in mainland Greece at the palace of Thebes (). There is no evidence for glass making or working at the Palace of Pylos, yet there is an abundance of glass beads there. The aim of this paper is to identify the technology and source for the glass of these beads and thus to ascertain how Pylos was connected to the broader Mycenaean and Mediterranean economies. The composition of the glasses was determined by means of portable XRF analysis and compared to that of other Late Bronze Age glasses from Egypt, Mesopotamia and mainland Greece. Four blue beads coloured with cobalt and one blue bead coloured with copper have Ti and Zr compositions consistent with an Egyptian origin of manufacture while five other beads show Ti and Zr concentrations consistent with a Mesopotamian origin (). Based on the dearth of Egyptian and Mesopotamian imports in Pylos, the presented data support the hypothesis that Pylos was receiving via internal Greek trade routes foreign-produced glass, which may have been worked abroad or in Greece.

Abstract: In recent years various methods of visibility analysis have been applied to investigate human engagement, experience and socialisation within historic and prehistoric ’natural’ and built environments. On many occasions these approaches appear to be either extremely limited or wholly inadequate for the interpretation of complex built structures and building interiors because they do not fully model the three-dimensional geometry of such spaces. This paper briefly reviews computational approaches to visual analysis that have been previously applied in archaeological research, and then goes on to introduce a new analytical technique that uses fully 3D reconstructions of past environments. This method integrates common functionalities of 3D modelling software and Geographic Information Systems (GIS), essentially permitting viewshed analysis to be performed upon objects of any form and shape modelled in 3D. We argue that the proposed methodology can generate new data and encourage fresh lines of enquiry in the study of extant and partially preserved historic and prehistoric built structures in a variety of contexts, ranging from building interiors and townscapes to landscapes. The potential of the method is illustrated by applying the suggested analysis to explore visual perception issues associated with the urban remains of Late Bronze Age Akrotiri (Thera, Greece).

Abstract: This paper refers to an investigation of finds that are associated with the raw materials and tools for the preparation or use of lead pigments at Akrotiri on Thera, Greece, during the Early, Middle and Late Cycladic Bronze Age (c. 3000–1600 BC). For the detection and the preliminary characterisation of remains of pigments that were found on stone tools, the in situ application of X-Ray Fluorescence spectroscopy proved to be invaluable. In order to identify the chemical composition of the pigments and to investigate their provenance from a geological perspective, quantitative X-Ray Diffraction analysis was conducted. A thorough visual macro and microscopic examination of the morphology of the materials permitted the determination of physical features (colour, homogeneity, grain size) as indicators of their nature or degree of processing. Based on the results of these analyses, the traces of lead oxides that were detected on the stone tools are associated with specific collections of litharge items discovered at the settlement of Akrotiri, and probably provide evidence of their earliest use in preparing pigments.

Abstract: From the rather difficult excavations that have taken place in Thebes since the beginning of the last century, many fragmentary but often well-preserved paintings on plaster have been unearthed. These belong to several contexts and periods: House of Kadmos (Late Helladic IIIA), Treasury Room (Late Helladic IIIB1) and Oikopedon Spourli (Late Helladic III). Their iconography, style and technology fit well with other paintings from the Late Bronze Age sites found in the vicinity of Thebes (e.g. Gla and Orchomenos). This paper presents a technological study of the Bronze Age painted plaster from Thebes, Greece. The paintings were investigated by means of X-ray diffraction; stereo, reflected light and scanning electron microscopy; some by laser-induced breakdown spectrometry and by micro-Raman spectroscopy, in order to identify the pigments and the composition of the plaster layers, and to determine the painting technique(s) that the artisans may have employed. The plaster layer onto which the paint layer was applied was often the only layer and consisted mainly of calcite, while a clay plaster formed the backing between the lime plaster coat and the actual wall surface. The pigments identified were: yellow ochre, haematite (red), cuprorivaite (Egyptian blue), indigo and possibly riebeckite for blue, charcoal (black), calcite (white), and a combination of black and red for purple. A detailed macroscopic study of the painted surface revealed several features, which indicated that the technique of al fresco painting was employed extensively, a technique already in use since the start of the Late Minoan I phase on Crete. A generally lower level of quality in the appearance of the later paintings (Treasury Room and Oikopedon Spourli) was also noted, but this was not reflected in the materials used or in their overall manipulation.

This paper assesses a series of experimentally generated cereal fragments with the aim to develop criteria for interpreting archaeological remains of ground cereals. Modern grain of einkorn and barley was subjected to processing by means of grinding, boiling and malting and then charred under controlled laboratory conditions. Neolithic replica grinding stones, cooking pots and hearths were used for the production of modern reference material, informed by ethnographic observations. In this way a range of different types of cereal fragments were generated. Our results are based on observations on the fracture surfaces of these cereals, using stereomicroscopy and Scanning Electron Microscopy (SEM). Diagnostic features for specific grain treatments have been identified that facilitate the interpretation of ancient foods using cereal fragments. Bulging of the fracture surface is the main criterion for the identification of fragments generated prior to charring as the result of ancient grinding. Parboiling of grain in a liquid towards the production of bulgur (boiled in water) or trachanas (boiled or soaked in milk/sour-milk etc) can be identified archaeologically and in certain cases, ground barley may be distinguished from ground malt. Charring ground grain during cooking in liquid or preparing wort for brewing is also potentially identifiable in archaeological material. Archaeological finds of ground wheat from Mesimeriani Toumba in northern Greece dated to the end of the 3rd millennium B.C. are interpreted as boiled grain, dried and ground, corresponding to some form of bulgur or trachanas. Our results contribute new information towards the identification of past culinary practices such as grinding, boiling and brewing with cereals. • A methodological tool for unlocking past ground cereal food preparations. • A key for the interpretation of charred archaeological cereal fragments. • Not all ancient cereal fragments are bulgur: cautionary notes on interpreting ancient cereal fragments. • Bulgur or trachanas , a Bronze Age 'fast food' stored in a burnt house at Mesimeriani, northern Greece.

The detection and interpretation of variability in archaeological data has been a long-standing effort in the field. This paper aims to introduce the application of Bayesian multilevel modelling as a tool for the detection of variability at levels within nested archaeological data. Model structure, ways of construction, and the potential of using variability information to enhance archaeological interpretations is presented. This is demonstrated through the analysis of two case study datasets: Neolithic pottery finds from Mala (Nova) Pećina cave excavations in Croatia and stone finds from the Bronze Age site of Akrotiri, Thera, Greece. This is followed by a discussion of the multilevel model results and the possible interpretations that can be derived from them. Finally, propositions are made on how these and other models can be extended. • Introduction of Bayesian multilevel modelling for studying variability in Archaeological data. • Application of a continuous response model to Bronze Age stone objects from the excavations at Akrotiri, Thera, Greece. • Application of a binary response logistic model to Neolithic pottery from the Mala (Nova) Pećina cave, Croatia • Discusses multilevel modelling as a tool for exploring variability in archaeology.
