The pottery described in this article was collected during a survey of ancient sites in eastern Turkey carried out in the summer of 1956. More than 150 Chalcolithic, Bronze Age and Iron Age sites were recorded: only the Chalcolithic and Early Bronze Age pottery is discussed here, the later periods being reserved for a future article. A considerable quantity of potsherds was collected, so that only a selection of the more significant examples has been illustrated. The zone covered by this survey is best described as eastern Anatolia within the mountains, excluding both the Pontic region and the south-eastern provinces of Turkey, bordering on Syria and Iraq: it is the narrowest part of the great natural bridge between Asia and Europe that has given Anatolia its long and varied history. The survey covered the greater part of the provinces of Sivas, Malatya, Elazığ, Muş, Bitlis and Van. Sites near Adıyaman, also visited, are not dealt with here. The plain of Iğdır, north of Mount Ararat, was partially explored in 1957, and yielded important material, but the plain of Karaköse proved to have few sites, and those with little surface pottery. The sherds here described are supplemented by intact vessels from Ernis, on the north-eastern shore of Lake Van, now in Van Museum.
