8. Of CONSTANTINOPLE, the younger, was born at Anaplus on the Propontis, and before his elevation to the patriarchate (A. D. 1222) was a monk of piety and learning. Though counted in the succession of the Greek patriarchs of Constantinople, he discharged the functions of his office at Nice, in Bithynia, Constantinople itself being then in the hands of the Latins. He was anxious for the union of the Greek and Latin churches, and wrote to the pope Gregory IX. a letter, of which a Latin version is included among the letters of that pope, and is given, with the version of a letter of Germanus to the cardinals, and the pope's answer, by Matthew Paris. (Historia Major, p. 457, &c., ed. Wats, fol. Lond. 1640.) The letters are assigned by Matthew Paris to the year 1237, instead of 1232, which is their proper date. The emperor Joannes Ducas Vataces was also favourable to the union, and a conference was held in his presence by Germanus and some ecclesiastics sent by the pope. A council on the subject was afterwards held (A. D. 1233) at Nymphaea, in Bithynia, but it came to nothing. Oudin affirms that after the failure of this negotiation, Germanus became as hostile to the Romish church as he had before been friendly. According to Cave and Oudin, Germanus was deposed A. D. 1240, restored in 1254, and died shortly after; and their statement is confirmed by Nicephorus Gregoras (Hist. Byzant. 3.1, p. 55, ed. Bonn), who says that he died a little before the election of Theodore Lascaris II., in A. D. 1254 or 1255. According to other statements, founded on a passage in George Acropolita, 100.43, Germanus died A. D. 1239 or 1240.
