The article supplements the publication of the introduction to Theophan Prokopovych’s philosophical course (taught at Kyiv-Mohyla Academy in 1707-09). It analyses characteristics of Prokopovych’s manuscript in comparison with the manuscript of Georgiy Konyskyi’s philosophical course (taught in 1747-1749). The latter turns out to be a copy of the former, as it does not contain significant differences. The article describes the editorial principles of Prokopovych’s Prooemium and the significance of the text as well as gives short exposition of the content with (...) the analysis of references by Prokopovych. It explains some codicological and textological characteristics of both manuscripts. The analysis of textual relation between the two manuscripts shows that Konyskyi’s manuscript contains much more mistakes than Prokopovych’s manuscript. Most of more than a hundred variations between the manuscripts are mistakes in Konyskyi’s manuscript. The author supposes that the student, the scribe of Konyskyi’s manuscript, not completely understood rather complicated style of Prokopovych. Prokopovych’s position about the style of exposition shows balancing between humanistic and scholastic ideas. It states that Prokopovych refers usually to ancient authors. The references in the text are quite detailed, but not enough accurate. Half of them (6 out of 12) happen to be incorrect. It is probable that Prokopovych made references from memory. (shrink)
