Pigment analysis in Bronze Age Aegean and Eastern Mediterranean painted plaster by laser-induced breakdown spectroscopy (LIBS)

Laser-Induced Breakdown Spectroscopy (LIBS) was used in the examination of Bronze Age painted plaster samples from several sites in the Aegean and Eastern Mediterranean. The elemental content of paint materials was determined in most cases leading to the identification of the pigment used in agreement with data from analyses of the same samples with other established techniques. The analyses demonstrate that a virtually non-destructive technique such as LIBS provides sufficient data for the elemental characterisation of painting materials while in parallel has the capability for routine, rapid analysis of archaeological objects enabling the quick characterisation or screening of different types of artefacts. This certainly shows an important way forward in technological studies of fragile and scarce archaeological material.     

Fridtjof Nansen and the Aegean population exchange

This article examines Fridtjof Nansen’s role in elaborating the compulsory Greco-Turkish population exchange of 1923–1924. Thrust into a spiralling crisis, the League’s High Commissioner took on humanitarian, representational and negotiating roles having long-term as well as immediate impact, while the Norwegian’s emergence at Lausanne as chief spokesman for an agreement widely considered reprehensible invites scrutiny of his interventions. Drawing on recent publications and key archival sources, the analysis presses four strands of argument. First, while Nansen helped articulate the exchange idea along with Greece’s Eleftherios Venizelos, he neither originated it nor provided the essential political impetus. Second, Nansen’s oft-cited ‘first mention’ of making it compulsory assigns him a misleadingly strong role in a solution chiefly engineered by Kemal’s Turkey. Third, his impact on the agreement’s scope, involving exemptions for minority populations in Western Thrace and Constantinople, was limited. Fourth, Nansen’s ultimate push for a lasting settlement blended pragmatism with strategic vision. Subsequent delays and wider political failure not of his making to secure equitable property exchange highlighted the harsher aspects of a deal all the main parties in fact favoured, Nansen recognized as necessary and which thwarted a still worse calamity.     

The Earliest Harbour Installations on Aegean Foreshores

This article aims to raise awareness of a few newly discovered prehistoric harbour facilities in Crete. In particular is an unusual, if not unique, slipway suggesting how large ships were hauled up on to the land at Middle Minoan II Kommos. Also, there are huge, successive structures (Buildings T and P) with long galleries that served as shipsheds inviting close scrutiny, as well as comparison with the later Classical shipsheds sheltering elite warships of the Greek city states. The three newly excavated Minoan buildings fit historically into the beginning of a now extended tradition of Classical shipsheds. The latter are compared here with their prehistoric counterparts and briefly discussed concerning origin, development, and aspects of cultural or historical significance.     

Keeping an eye on your pots: the provenance of Neolithic ceramics from the Cave of the Cyclops,Youra, Greece

Combined petrographic and chemical analysis of MN and LN ceramics from the Cave of the Cyclops on the island of Youra, Greece, has revealed a compositionally diverse assemblage with a range of different local and off-island sources. Ceramics deposited in Neolithic times on this barren, rocky outpost of the Sporades chain may have originated from a surprising number of possible origins, including from the Plain of Thessaly, Euboea and the volcanic northeast Aegean islands. This picture challenges traditional assumptions about Neolithic pottery production and indicates that significant movement of ceramics was already taking place within the northern Aegean as early as the beginning of the sixth millennium BC. The discovery of a persistent local pottery tradition, that is also found on the neighbouring island of Kyra-Panagia, indicates significant continuity in ceramic technology over some 1500 years.     

Iron Age hydraulic plaster from Tell es-Safi/Gath,Israel

Hydraulic plasters or mortars prior to the Roman period are rare. Here, we report the identification and characterization of 3000 year old (Iron Age) hydraulic plaster surfaces from the site of Tell es-Safi/Gath. This site, located in central Israel, was occupied almost continuously from prehistoric through modern times, and is identified as the Canaanite and Philistine city of Gath. A survey using an on-site Fourier transform infrared spectrometer (FTIR) identified the presence of amorphous silicates, in addition to calcite, in each of two superimposed plaster layers. This suite of minerals is characteristic of hydraulic plaster. An in-depth characterization of the plasters using FTIR, acid dissolution, X-ray fluorescence (XRF), X-ray powder diffractometry (pXRD), heating experiments and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (SEM–EDS), shows that special silicate-containing minerals were brought from some distance to the site in order to produce these plaster surfaces. We therefore conclude that the plasters were deliberately produced, and were not the result of a fortuitous addition of local silicate minerals. A layer of around 150 μm thick enriched in carbonate hydroxylapatite was found in both plaster surfaces, and the same mineral was identified by infrared spectrometry in the surrounding sediments. This suggests that organic materials were used on these surfaces. These surfaces are among the oldest hydraulic plasters known.     

Handheld Portable X‐Ray Fluorescence of Aegean Obsidians

We tested two portable XRF instruments (with different technologies) using two correction schemes (‘soils’ and ‘mining’) with both factory‐set calibrations and linear regression calibrations derived from published data. All four Aegean obsidian sources, including Sta Nychia and Dhemenegaki on Melos, were distinguished in each case. The newer instrument provided better ‘off‐the‐shelf’ accuracy than the older instrument, but calibrations negated these differences. The newer model also offered superior precision for most elements, despite measuring specimens for shorter times. Both correction schemes for the newer instrument resulted in almost equal precision, meaning that either may be used for successful Aegean obsidian sourcing.     

Tracing population mobility in the Aegean using isotope geochemistry: a first map of local biologically available Sr/Sr signatures

Strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) analysis of archaeological human skeletal remains is an efficient method of investigating past population movement and residential mobility by determining probable geographical origins for the individuals examined. For this to be achieved, however, a map of biologically available ⁸⁷Sr/⁸⁶Sr signatures across the region investigated is needed. This paper presents a first such map for the Aegean, based on ⁸⁷Sr/⁸⁶Sr values recovered mainly from archaeological animal dental enamel and modern snail shells from sites largely distributed in the southern part of this region. Although not exhaustive, this comprehensive dataset of local biologically available ⁸⁷Sr/⁸⁶Sr signatures shows a marked difference between Mainland sites of the Pindos and Parnassos zones and the islands of south-eastern Aegean crossed by the Sub-Pelagonian zone (0.70808–0.70869), and sites in the central Cyclades and the north-eastern Aegean islands falling into the Attic-Cycladic metamorphic belt and the Vardar zone, respectively (0.70926–0.71187). Biologically available ⁸⁷Sr/⁸⁶Sr values from sites on central Euboea in the Pelagonian zone, south-eastern Attica and the western Cyclades in the Attic-Cycladic metamorphic belt, and on Crete in the Gavrovo zone are also relatively high (0.70853–0.70931), but lower than those recorded for the central Cyclades and the north-eastern Aegean.     

From charting to mapping: Russian military mapping of Corfu in the early nineteenth century

Abstract

This paper concludes the overview of the Russian Navy's chart making published in Imago Mundi, Volume 52 (2000). In the present paper attention is drawn to the way the emphasis shifted in the early years of the nineteenth century from charting by naval surveyors to land mapping by the Army. The need for specialized military topographical education had led to the founding of the Map Depot in 1797 in St Petersburg. The first major survey undertaken by the Depot was of the island of Corfu (1804–1806), in anticipation of further Russo‐Turkish hostilities (the Third Russo‐Turkish war, 1806–1812).     

Re-investigating fish consumption in Greek antiquity: results from δC and δN analysis from fish bone collagen

One of the frequently encountered issues in ancient Greek dietary reconstructions through isotope analyses has been the apparent unimportance of fish protein in human diets. The significance of this observation is amplified by the abundant ichthyofaunal remains, iconographic evidence and literary information on fish and fishing, pertaining to almost all sites and time periods of Greek antiquity. In this project, we measured for the first time isotopes from a large number of fish bones from Greek sites dating from the Mesolithic to the Classical times, aiming to investigate whether this absence is an artefact of the methodology or whether it reflects a reality of restricted fish consumption. Results show that regional trends are stronger that temporal ones in fish isotope values. The range of values overlaps with terrestrial resources, making it difficult or impossible to reject fish consumption based on isotope data alone. This variability proposes a reconsideration of the amount of fish in ancient Greek diets specifically for each site and amplifies the importance of interdisciplinary studies, especially for regions with variable ecological resources.     

“Mycenaean” political domination of Knossos following the Late Minoan IB destructions on Crete: negative evidence from strontium isotope ratio analysis (Sr/Sr)

Strontium isotope ratio analysis of human dental enamel and bone is applied to investigate a highly debated question of population movement and cultural discontinuity in Prehistoric Aegean Archaeology. The Late Minoan IB (ca. 1490/1470 BC) destructions on Crete are succeeded by cultural upheaval. The novel cultural features that appear at Knossos (Crete) in this period have forerunners in the Mainland. In Cretan context, the Linear B writing system, the funerary architecture and burial practices of the Mainland style are interpreted as evidence of an actual “Mycenaean” long-term settlement and political domination of Knossos. Human skeletal material from tombs that are associated with non-locals from the Mainland based upon the material culture is analysed to measure ⁸⁷Sr/⁸⁶Sr. The results of the analysis show that all the examined individuals from the Knossos tombs were born locally.
