Etrusco-Attic, and Latino-Sicilian Commerce
A distinction not less remarkable between the commerce of the Latins and that of the Etruscans appears in their respective routes or lines of traffic. As to the earliest commerce of the Etruscans in the Adriatic we can hardly do more than express the conjecture that it was directed from Spina and Atria chiefly to Corcyra. We have already mentioned(24) that the western Etruscans ventured boldly into the eastern seas, and trafficked not merely with Sicily, but also with Greece proper.
24. Cf. I. X. Etruscan Commerce
An ancient intercourse with Attica is indicated by the Attic clay vases, which are so numerous in the more recent Etruscan tombs, and had been perhaps even at this time introduced for other purposes than the already-mentioned decoration of tombs, while conversely Tyrrhenian bronze candlesticks and gold cups were articles early in request in Attica. Still more definitely is such an intercourse indicated by the coins.
The silver pieces of Populonia were struck after the pattern of a very old silver piece stamped on one side with the Gorgoneion, on the other merely presenting an incuse square, which has been found at Athens and on the old amber-route in the district of Posen, and which was in all probability the very coin struck by order of Solon in Athens. We have mentioned already that the Etruscans had also dealings, and perhaps after the development of the Etrusco-Carthaginian maritime alliance their principal dealings, with the Carthaginians.
