Niphont bishop of Novgorod, a Russian prelate of note, flourished near the middle of the 12th century. He died at Kief April 13, 1156. He is considered 'as one of the continuators of the Chronicles of Nestor.' Herberstein has inserted in his Commentaries a series of questions, some of them being of the strangest character, which were submitted to Niphont, with the replies which he made to them — replies which at present serve as law to the Russian clergy. The catalogue of the manuscript library of count Tolstoi contains, under Nos. 204 and 212, two sermons attributed to this bishop. See Tatichtchef, Hist. de Russie, vol. ii; Dict.
