Wielowymiarowe analizy statystyczne jako narzędzie do podziału typologicznego form naczyń na przykładzie wczesnośredniowiecznej ceramiki z Wiślicy

The article presents the formal diversity of the Early Medieval vessels from Wiślica. The vessels were described by means of proportions of dimensions and stylistic features, treated as nominal variables, which became the basis for statistical analysis (cluster analysis and principal components analysis). The measurement scheme is presented in figure 2. Based on the obtained results, vessels have been divided into 8 types. The first four ones included pots with a S-shaped profile. Other types consist of vessels with one, more visible element, i.e.: there are vessels with a cylindrical neck in type V, vessels with a long, straight neck, with a strongly flaring rim in type VI, vessels with an angular connection between the neck and the body, marked with a fault are included in type VII, and double-conical vessels are in type VIII. What is more, an attempt has also been made to trace the relative chronology of pottery vessel types, based on stratigraphic relations observed at the sites, where they were excavated. In the case of vessels type VI-VIII, it allowed us to determine their most probable period of occurrence. Other vessels belong to long-lasting forms.
