Chantre in 1894 picked up lustreless ware, like that of Hissarlik, in central Phrygia and at Pteria, and the English archaeological expeditions, sent subsequently into north-western Anatolia, have never failed to bring back ceramic specimens of Aegean appearance from the valleys of the Rhyndacus, Sangarius and Halys.
