Constantinus II

was 47th patriarch of Constantinople, A.D. 745, according to Theophanes (Chronog. page 660). He had previously been a monk and bishop of Syllium. In A.D. 764, owing to the emperor Constantine Copronymus's ill- will, he was exiled, and in 767 was deposed by Nicetas, who afterwards succeeded him. After enduring horrible cruelties from his enemies, he was beheaded in the year 776 (Niceph. Constantin. Breviarium, page 48). See Smith, Dict. of Christ. Biog. s.v.
