The seminar unites mathematics, archaeology, and the art of ornamentation. Through the ideas of symmetry and the legacy of Florensky, participants will see how patterns become the key to the structure of culture and thought. The conversation is prompted by the book of Academician Parshin, where ornament is viewed not as a decorative detail, but as a system or as a map of meanings by which cultures navigate the world. This gives rise to deep connections: patterns set the script in rituals and folklore; symmetry maintains order in mythology; repetition reduces anxiety in the psychology of perception. The organizers of the event maintain an atmosphere of a research workshop, where one can debate, clarify, test hypotheses, and immediately see results on visual material. The seminar will be beneficial for students and teachers, cultural researchers, museum workers, architects, graphic and textile designers, and anyone working with traditional motifs or seeking a foundation for their own solutions.
