At the start of the Neolithic in the Aegean, communities increasingly relied on obsidian (volcanic glass) for very sharp cutting edges. Melos (Milos) stood out because it had major obsidian sources—especially Sta Nychia and Dhemenegaki—that could supply islands and coasts far beyond the Cyclades. This set the stage for long-distance movement of raw stone well before written records.
At Franchthi Cave (in the Argolid), Melian obsidian appears together with evidence for open-sea fishing, implying repeated boat travel and exchange across the Aegean. The obsidian shows that people were moving materials over water as part of their everyday economic life, not only during rare “expeditions.” These early connections help explain how Melian obsidian spread widely despite the distance from its source.
At the Cyclops Cave on the islet of Youra (Gioura), Mesolithic-to-Neolithic layers include obsidian among other stone tools. This shows that Melian obsidian was not limited to a single route or destination; it was part of broader island networks tied to fishing and seasonal movement. Sites like this help fill out a map of how exchange operated across many islands.
The Mesolithic settlement of Maroulas (Kythnos) produced abundant obsidian and is interpreted as lying along a main navigation route moving Melian obsidian toward Attica and the Greek mainland. This matters because it suggests a step-by-step (“island hopping”) system, where some places acted as regular stops that supported repeated transport. The site also indicates that exchange could be integrated into stable communities, not just temporary camps.
Scientific sourcing work (using chemical signatures) has shown that Aegean obsidian artifacts can be linked to specific Melos outcrops, especially Sta Nychia and Dhemenegaki. This allows archaeologists to reconstruct exchange patterns rather than assuming them from proximity alone. The result is stronger evidence that Melos supplied wide areas over long periods.
By the early Neolithic, domesticated plants and animals appear in Aegean sites such as Franchthi, marking a major economic shift toward farming. Obsidian still circulated during this transition, meaning exchange networks continued even as daily production and food systems changed. In practice, the same maritime contacts that moved obsidian also supported wider communication among communities.
Material evidence summarized by museums and excavations indicates that Melian obsidian reached many parts of the Aegean and beyond, reflecting frequent maritime movement. This widening network helped connect island communities and coastal regions into shared systems of contact. Over time, obsidian became one of the clearest archaeological tracers of those connections.
In western Anatolia, evidence from sites such as Liman Tepe and Bakla Tepe indicates that obsidian circulation was uneven, with certain coastal settlements acting as key nodes in long-distance exchange. Melian obsidian appears among the materials moving through these networks, showing that Aegean exchange was not confined to Greece. This phase highlights how hunter-gatherer and early farming exchange systems developed into larger interregional connections.
Toward the end of the 4th millennium BCE, metallurgy (metal toolmaking) began to spread in the Aegean, changing how people made tools and weapons. However, obsidian did not simply disappear; sharp stone blades remained useful and continued to circulate. This overlap shows technological change happening through addition and adaptation, not immediate replacement.
In the Early Bronze Age, maritime contacts and trade networks expanded, supporting larger and more connected communities across the Aegean. These wider links provided more pathways for distributing materials, including Melian obsidian, alongside newer metal items. The exchange of toolstone thus became part of a broader trade environment, not a standalone system.
Studies of western Anatolian assemblages report a sharp increase in Melian obsidian use during the first half of the 3rd millennium BCE, reflecting intensified Aegean-facing exchange. Later in the millennium, there is growing evidence for additional obsidian sources entering these networks, indicating changing supply options and relationships. This marks a shift from a largely Melos-centered pattern in some areas to more mixed sourcing.
By around 2000 BCE, the Aegean was firmly in the Bronze Age world, with metallurgy and complex regional exchange increasingly shaping daily life. Melian obsidian continued to be used, but its distribution now operated within broader systems that also moved metals and other goods. This point provides a practical end state for the hunter-gatherer-to-early-farming exchange story that began millennia earlier.
