set of parallels and differences between each other and with regard to other contemporary pottery styles. In the study area, extending from the Carpathian Basin to the northern European Lowlands (fig. 3), sev-en different pottery styles can be identified. Figurę 4 shows the cor-respondence analysis of the pottery decoration motifs (192 different motifs classified) from settlement materiał in Moravia, Upper Silesia and Lesser Poland during the period from 3650 to 2900 cal BC. Besides an overall temporal trend in axis 1, there is a certain degree of cluster-ing (clusters 1 to 4), indicating discontinuities in the similarity matrix. These are the foundation for the definition of Baden Pottery Styles.
