It is long known that members of the large Early Bronze Age [EBA] 3rd millennium cal BC coastal community of Poliochne on the northern Aegean island of Lemnos were able to access an array of overseas raw materials, goods, and practices, many of which served to create, and display social status. The socio-economic networks that coalesced at the site facilitated long-distance connections with the larger Aegean world, Anatolia and Mesopotamia beyond, albeit often likely articulated via intermediaries, rather than directly. In this study, we focus on an assemblage of 28 artifacts flaked from obsidian, a relatively rare natural occurrence in the larger region, with the most significant sources being located on Melos (Cyclades), and Cappadocia (central Anatolia). A multi-faceted characterization study of this material, melding elemental data generated by a portable XRF spectrometer [pXRF], and the artifacts’ techno-typological attributes, allow us to show that (a) the assemblage is comprised entirely of obsidian from the Melian source of Sta Nychia, (b) that the material was procured in the form of preformed pressure blade cores and/or ready-made end-products, and (c) that this material was likely brought to Lemnos by Cycladic voyagers, rather than being procured indirectly via western Anatolian intermediaries. The artifacts derive mainly from contexts dated to the first half of the 3rd millennium cal BC, a period of significant overseas Cycladic cultural influence. This Cycladic underpinned ‘international spirit’ involved a range of goods and practices developed by these islanders being accessed, adopted and/or emulated by communities in the surrounding region. This included socially significant modes of body modification, via tattooing and depilation, as evidenced at Poliochne (and elsewhere) by bone tube pigment containers, and obsidian razors pressure flaked from Sta Nychia obsidian.
