The last six leaves of the manuscript Zavorda, Monastery of St Nikanor, 5 contain glosses by various authors (Origen, Theodore of Heraclea, Apollinarius, Cyril of Alexandria, etc.) on the Gospel of Matthew (Mt 1:17–2:9 and 3:5–3:15). These leaves are a detached fragment from a ninth-century codex, the rest of which no longer survives. Comparison with other known exegetical collections shows that they represent a distinct, previously unidentified type of catena commentary. We describe their content and compare it to several related catenae, thus shedding new light on the genesis of various Matthaean commentaries.
