A multi-national team of archaeologists has uncovered evidence of a previously unknown 2,500-year-old trade network, dubbed the 'Sulphur and Silk' Route. By analyzing the chemical signatures of sulphur deposits found in ancient Phoenician ports, researchers have traced the mineral's origin back to the volcanic depressions of Mount Etna in Sicily. The findings suggest that high-purity sulphur was a critical commodity traded across the Mediterranean for its use in textile bleaching and medicinal preparations during the Classical period.
In exchange for the Sicilian minerals, local populations received luxury items from the Levant, including early silks and purple dyes. This discovery reshapes our understanding of the economic ties between Classical Greece, the Phoenician city-states, and the indigenous Sikel tribes. The research, published in the journal Ancient Maritime Economics, highlights the complexity of early industrial supply chains and the strategic importance of volcanic resources in shaping ancient Mediterranean geopolitics.
