Perykopy liturgiczne okresu po święcie Pięćdziesiątnicy w dwu serbskich apostołach-ewangeliarzach krótkich (Sv-17 i KM-512)

The article is devoted to two Serbian Apostol-Gospel abbreviated lectionaries, from collections: the Russian State Library in Moscow, P.I. Sevastianov collection (f. 270), no. 17 (Sv-17) and Bulgarian National Library (St.St. Cyril and Methodius) in Sofia, no. 512 (KM-512). The collation of liturgical readings from the Gospel of Matthew (from second period of Synaxarion (after Pentecost)), based on 70 manuscripts, has shown that these two Cyrillic manuscripts have unusual textual readings (translation, additions, omissions, harmonizations, etc.) that are characteristic only for these two lectionaries. On this basis Sv-17 and KM-512 can be classified as textologically homogeneous manuscripts with common archetype.
