Blade production and the consumption of obsidian in Stentinello period Neolithic Sicily

This study explores obsidian consumption during the Early/Middle Neolithic Stentinello period (ca. 5600–4000 cal B.C.) on the Italian island of Sicily through the analysis of 622 obsidian artifacts from eight sites in eastern Sicily and the Aeolian Islands. By combining obsidian sourcing by means of portable X-ray fluorescence (pXRF) spectrometry with techno-typological characterization, it is shown that distinctively wide Lipari blades were the primary artifact type used during this period. Our data suggest that the primary reduction of these materials occurred at the source area by local populations, with obsidian being transported from Lipari to eastern Sicily and Calabria in the form of preformed cores. Despite similarities between Sicily and southern Italy in the initial procurement of Lipari obsidian, there are distinct differences in how these materials were subsequently reduced.
