Around 650 BC, or a little earlier, Greeks from Paros founded a colony on Thasos.[9] A generation or so later, the poet Archilochus, a descendant of these colonists, wrote of casting away his shield during a minor war against an indigenous Thracian tribe, the Saians.[10] Thasian power, and sources of its wealth, extended to the mainland, where the Thasians owned gold mines even more valuable than those of the island; their combined annual revenues amounted to between 200 and 300 talents. Herodotus says that the best mines on the island were those opened by the Phoenicians on the east side of the island, facing Samothrace. Archilochus described Thasos as “an ass’s backbone crowned with wild wood.” The island’s capital, Thasos, had two harbours. Besides its gold mines, the wine, nuts and marble of Thasos were well known in antiquity.[8] Thasian wine was quite famous. Thasian coins had the head of the wine god Dionysos on one side and bunches of grape of the other.[11]
