Nikephoros II Phokas
John was probably of noble descent, but other relatives have not been identified. He was well educated and served in the Byzantine army before retiring as a monk. His career encompassed the eventful reigns of Nikephoros II Phokas (r. 963–969), John I Tzimiskes (r. 969–976) and the early years of Basil II (r. 976–1025). As a result, his poetry is full of references to the contemporary Byzantine conflicts with the Bulgarians and the Rus', as well as the rebellions of Bardas Skleros and Bardas Phokas. Among the Byzantine emperors, he singles out Nikephoros II Phokas for particular praise, while he denigrates his murderer and successor John Tzimiskes. He was previously erroneously identified with another John, Bishop of Melitene.
