Иоанн Дамаскин как вероятный автор древнеболгарской службы константинопольскому патриарху Герману I

The paper discusses the possibility that the Old Church Slavonic liturgical Service for Patriarch Germanus I of Constantinople is not an original Old Bulgarian composition, as is believed in modern scholarship, but a translation from an unknown (lost or still unidentified) Greek original. As a result of a retranslation of the Slavonic incipita of its Canon into Greek, it was possible to reconstruct (with varying range of probability) the original Greek acrostic which testifies to the translational nature of the Old Church Slavonic text of the Canon. Its author may be tentatively identified with the Greek hymnographer John of Damascus.
