Abstract: | ABSTRACT The Aegean island of Chios provides a special case of insularity during the Middle Ages, aspects of which are reflected in the production of a highly-valued product, mastic resin, which was sought after across the Mediterranean world for use in medicine, fragrances and flavourings. Produced only on the island, high-quality mastic became an iconic Chian product that highlighted the island’s uniqueness and significantly contributed to its economy. This article presents a diachronic view of mastic production in and circulation from Chios during the periods of Roman, Byzantine and Genoese rule. The widespread demand for its luxury commodity meant that the island was always active in the wider maritime networks in this period. The lens of mastic production makes these connections visible in textual, archaeological and architectural evidence that highlights the role local products played in the ways islands, like Chios, navigated the economic and political transitions of the medieval Mediterranean world. |
