Regarding the written prototype of the Triodium's First (1491) edition

The paper deals with the first edition of the Triodium performed by Sh. Fiol in Krakow in 1491. The manuscript sources of the text for one particular hymnografic text of the Triodium - namely the Akathistos Hymn - are determined. The comparative analyses of the text of the edition with the main manuscript versions of the Hymn for the period of XIV-XV century established the East Slavonic origin of the edition sources, and helped to see it in the context of the Church Slavonic manuscript tradition.
