The article treats the concept of proper name in Juri Lotman’s semiotics, taking into account also studies in the same field by other authors of the Tartu-Moscow school (V. Ivanov, B. Ogibenin, V. Toporov, B. Uspenski). Focus is laid at three sub-topics: name and myth, name and text, name and artistic creation. One of the sources of treating proper name for both the program article by J. Lotman and B. Uspenski (“Myth — Name — Culture”), and works by several other semioticians of the Tartu–Moscow school is confidence in the connection between proper name and mythical (a-semiotic) thought: semiosis equals here with nomination. Proper name plurality, different re-namings affirm the continuing importance of mythical thinking in later culture. Proper names (such as personal names, place names) belong, in addition to natural language, also into a certain individual system, forming thus an interlinguistic layer located on the boundary of language. J. Lotman stresses that art has a specific power of uniting general and proper name (proper name characterized here by individuality, explosiveness). An artistic work is even doubly of proper name character: both the act of creation and its reception are by nature individual and unrepeated. In the opinion of the authors the treatment of proper name by the Tartu-Moscow school contains fruitful and promising standpoints for the analysis of contemporary culture that, however, have been applied unjustifiably little.
