ENThe article describes the structure of the Old Church Slavonic manuscript copy of the Metrical Synaxarion for March-August, which has been compiled, according to its colophon, in the town of Bielsk in 1496 (now kept in the Wroblewskie Library of the Lithuanian Academy of Sciences, F 19-100). The research of the texts for June-August shows that this manuscript copy of the Metrical Synaxarion contains certain texts of the Non-Metrical Synaxarion, as well as some conflated texts which combine characteristics of both (metrical and non-metrical) types of the book. It may be concluded that this specific manuscript represents the Verse Synaxarion in its previously unknown edition, which originated in the Grand Duchy of Lithuania.
