Emil Kraepelin, a German Psychiatrist, may be considered as the grandfather of Diagnostic and Statistical Manual for Mental Disorders (DSM). Before the DSM was published, he had already an attempt of classifying mental illnesses by grouping its similar symptoms. He had developed a system to make distinctions of different disorders.

This concept became the basis of the DSM-III, which is quite different from earlier versions that are pyschodynamically oriented.

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.

One difference between a more and a folkway is the following: Mores may carry serious consequences if violated; folkways do not. Folkways on the other hand are norms for routine or casual interaction.
