Interest in biography is steadily growing in modern Russian society. Mythologized concepts, stamps and "dark spots" are increasingly discredited by archival data. The article is devoted to the scientific biography of the candidate of Historical Sciences, associate professor of the Department of General History N. N. Belova (1917-2012). The author reconstructs the course of work of the Soviet epigraphist on the problems of dialectical continuity based on archival materials. In the second half of the 1960s, N. N. Belova worked on a set of problems concerning the Gallo-Roman villa as an economic unit connected with the city. N. N. Belova considered the history of the late Roman Republic and the Gallia of the principate era as the history of the relationship between Rome and Italians, i.e., the struggle of Italian communities against Roman-Italian slavery. The author used a biobibliographic method, as well as developments in the field of everyday history. The article presents for the first time a letter from M. Ja. Sjuzjumov to N. N. Belova. The materials presented in this article allow us to highlight an important aspect of the scientific work of the outstanding Soviet historian M. Ja. Sjuzjumov (1893-1982) - the study of the genesis of the ancient city. The most important result of the work was the formation of the most important milestones of the scientific biography of N. N. Belova, a historian who is part of the "inner circle" of M. Ja. Sjuzjumov.
