Öz A prolonged stay at the excavations at Kültepe in. 1965 gave me the initial impulse for the idea put foreward in. the present paper. At the outset I wish to express my indebtedness to Professors Drs. Tahsin and Nimet Özgüç for the invitations to thcir digs at Kültepe and Acemhüyük, and for the İcarning and discussions they both have generously edified me with. The similarities bctween the two ceramic cultures are manifested both in some basic general characteristics as well as in various typcs and forms. Hovvever, perhaps the most significant point of similarity lics in the fact that these two ceramic cultures constitute each in its own arca quite a break with its prcccding culture. In both arcas, as we shall presently see, the two cultures are quite a complclc novelty.
