In this article, the shape of 14th–15th century pottery from Subačiaus Street 11, Vilnius, is analyzed through the application of big data analysis techniques (relational data model, Structured Query Language (SQL), programming language Python, and statistical methods). Two main tasks were carried out as part of this study, namely, the classification of the earliest shapes of pottery found in the potter’s workshop in Vilnius and the implementation of IT methods in the research of archaeological household pottery of Vilnius. A total of 1628 fragments of the upper part of vessels and complete vessels from two middens were analyzed to discern a morphological relationship of assemblages, to assess the diversity of shapes, as well as similarities and differences in techniques used during production. Further tasks include the classification of the shape of rims, profiles, and decorations. Both middens were found to contain pairs of similarly shaped sherds, leading us to conclude that although production was characterized by similar features, they were not identical—possibly due to minor differences in the chronology of the assemblages, different circumstances of artifacts’ deposition in archaeological layers, or because the two middens were used by several craftsmen with a common work experience.
