clay cones, a terracotta sickle, an accounting bulla imprinted with the pattern from a cylinder seal, an uninscribed clay tablet, etc. This material co-exists with local pottery, which remains dominant throughout. The excavator of the site thinks that there was an enclave of people from Lower Mesopotamia who lived on the site alongside a majority population of local people. Other sites have been excavated in the region of Samsat (also in the Euphrates valley). An Urukian site was revealed at Samsat during a hasty rescue excavation before the area was flooded as a result of the construction of a hydroelectric dam. Fragments of clay cones from a wall mosaic were found. A little to the south is Kurban Höyük, where clay cones and pottery characteristic of Uruk have also been found in tripartite buildings. Further to the north, the site of Arslantepe, located in the suburbs of Malatya, is the most remarkable site of the period in eastern Anatolia. It has been excavated by M. Frangipane. During the first half of the 4th millennium BC, this site was dominated by a building called 'Temple C' by the excavators, which was built on a platform. It was abandoned around 3500 BC and replaced by a monumental complex which seems to have been the regional centre of power. The culture of Late Uruk had a discernible influence, which can be seen most clearly in the numerous sealings found on the site, many of which are in a south Mesopotamian style. Around 3000 BC, the site was destroyed by a fire. The monuments were not restored and the Kura–Araxes culture centred on the southern Caucasus became the dominant material culture on the site. Further west, the site of has also revealed pottery influenced by that of Uruk. But in this region, the Urukian influence becomes increasingly ephemeral, as one gets further from Mesopotamia. The 'Uruk expansion' After the discovery in Syria of the sites at Habuba Kabira and Jebel Aruda in the 1970s, which were rapidly decided to be colonies or trading posts of the Uruk civilisation settled far from their own lands, questions arose about the relationship between Lower Mesopotamia and the neighbouring regions. The fact that the characteristics of the culture of the Uruk region are found across such a large territory (from northern Syria to the Iranian plateau), with Lower Mesopotamia as a clear centre, led the archaeologists who studied
