This paper suggests to eliminate various difficulties concerning Weber's urban typology by offering some tentative modifications dependent on the needs of the researcher. The dichotomy of urban behavior, the appreciation and use of which is seriously hampered by an exceptionally poor translation, is one of the most important of Weber's typological dichotomies. In addition, due to the unfinished condition of Weber's opus there are several analytical ambiguities which need clarification. Recent outstanding contributions in the sociology of Islam, specifically of the Islamic medieval city, seem to support the validity of Weber's hypotheses. The evidence offered by recent studies of the ancient Mesopotamian as well as the Greco-Roman city is considered in relation to Weber's urban typological dichotomy.
