This article outlines some general aspects of the Magan and Dilmun trade and goes on to examine the Umm an-Nar pottery discovered in the tombs of the Early Dilmun burial mounds of Bahrain. These ceramics are of particular interest because they indirectly testify to Dilmun’s contact with Magan in the late third millennium. In this article, thirty vessels of seven morphological types are singled out. By comparison with the material published from the Oman peninsula the Bahrain collection is tentatively dated to c.2250–2000 BC. The location of the Umm an-Nar pottery within the distribution of burial mounds reveals that its import was strongly associated with the scattered mounds of Early Type. It is demonstrated that the frequency of Umm an-Nar pottery declined just as the ten compact cemeteries emerged c.2050 BC. The observed patterns are seen as a response to the decline of Magan and the rise of Dilmun.
