Ioannes 84 was bishop of Tauromeneia (Tauromenion) (in Sicily); 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 994-XIII 486. In the lists of those present at the first and seventh sessions he is styled Ἰωάννου ἐπισκόπου Ταυρομενείας: Mansi XII 994, XIII 365 (Ταυρομενίου). Elsewhere he is styled Ἰωάννης ὁ ὁσιώτατος ἐπίσκοπος Ταυρομενείας or similar: Mansi XII 1094, 1151, XIII 140, 384, 24. At the second session he spoke in support of the traditional veneration of icons as described in statements from pope Hadrian I (Hadrianos 1) and condemned iconoclasts: Mansi XII 1094. At the third session he accepted as orthodox the statements of the faith contained in letters from Tarasios 1 and the eastern patriarchs; he also accepted the veneration of images and anathematised iconoclasts: Mansi XII 1151. At the fourth session he confirmed a statement by Petros 27 and Petros 28 about the icon of Anastasios the Persian at Rome and recorded how a demented lady in Sicily visited Rome and was cured by it: Mansi XIII 24. Later at this session he subscribed the statements read out from the Fathers in support of the veneration of icons: Mansi XIII 140.
