From the Museo Archeologico Paolo Orsi in Siracusa, this door slab with carved spiral, anthropomorphic motifs is from the early Bronze Age. It’s dated to be from sometime between the 22nd and 15th century B.C. and was collected from a tomb in Castelluccio, an archaeological area between Noto and Palazzolo Acreida in southeastern Sicily. Yes, yes … it’s not just you … scholars believe it to be a “diagrammatic representation of the sexual act.”
