Niketas 20 was bishop of Dadybra in Paphlagonia; in 787 he attended the Second Council of Nikaia (the Seventh Ecumenical Council) and was probably present at all eight sessions, from 24 September to 23 November 787: Mansi XII 998-XIII 486. In the lists of those present at the first and seventh sessions he is styled Νικήτα ἐπισκόπου Δαδύβρων: Mansi XII 998, XIII 369. Elsewhere he is styled Νικήτας ὁ ὁσιώτατος ἐπίσκοπος Δαδύβρων or similar: Mansi XII 1103, XIII 145. At the second session he supported the traditional veneration of icons as described in statements from pope Hadrian I (Hadrianos 1) and condemned iconoclasts: Mansi XII 1103. At the fourth session he subscribed the statements read out from the Fathers in support of the veneration of icons: Mansi XIII 145. His name is missing from the list of those who subscribed the statement of the faith adopted by the Council at the seventh session, probably through a textual error, since he was present at the session; his name may be missing in a lacuna at Mansi XII 392.
