On the Prologue Lives of Constantine-Cyril and Methodius

The article focuses on three prologue texts dedicated to the Slavic first teachers Constantine-Cyril the Philosopher and Methodius. The earliest of them is the Prologue Life of the Two Brothers, which probably arose in the 10th century and is preserved in three complete texts, the last of which was discovered and published by prof. Rumyana Pavlova. The contribution of R. Pavlova to the correct interpretation of a basic passage of the work is highlighted. The second part of the study provides information about new copies of the Prologue Lives of the two brothers, which became known thanks to digitized manuscripts and library inventories on the website of the Russian State Library.
