An overland route by which oriental merchandise and ideas were transmitted to the Ionian Greeks via the Anatolian plateau and the river valley routes of the west was long ago posited by Hogarth, and supported by Karo, Barnett and others, although there was little evidence from central Anatolia to confirm it. More recently this route was virtually discounted in favour of a sea route from N. Syria, especially Carchemish, through the port of Al Mina, to Greece and Etruria, via Cyprus, Rhodes and Crete, discussed by Sidney Smith, Humphrey Payne, Mrs. Maxwell-Hyslop and others, which is assumed to have been at its height in the earlier eighth century; and Barnett has also shown the importance of a third route, from Azerbaijan to Trebizond and west via the Black Sea, for which the main evidence, a tomb group from the Caucasus, is probably later seventh century.
It is clear that the second of these three routes carried the bulk of Oriental trade to Greece and the west. Undoubtedly the most important Orientalizing influences on Greece, as shown by Payne, were those from the Cypro-Levantine cultural province, and there is ample evidence of the exchange of pottery, terracottas and ornamental bronzes of Cypriot and Phoenician production between the Syrian coast, Cyprus, Rhodes, Samos, Miletus, Chios, Delos and the west.
