John Diakrinomenos (Greek: Ἰωάννης Διακρινόμενος, romanized: Ioannes Diakrinomenos, latinized Diacrinomenus) was a Byzantine ecclesiastical historian of the early 6th century. His nickname refers to his theology: he was one of the "hesitants" (diakrinomenoi) who rejected the Council of Chalcedon. Working in Constantinople, he wrote a history of the church in ten books covering the period from the Council of Ephesus in 431 down to the start of the patriarchate of Severus of Antioch in 512. He dedicated it to his uncle, Bishop Silvanus, who was sent by Emperor Anastasius I to the kingdom of Himyar in 512. It is now lost. There survives only a summary of each book. Already in the 9th century Patriarch Photios I of Constantinople only had access to the first five books,^[1] which he included in his Bibliotheca.^[2] The fifth book ended with the expulsion of the Peter the Fuller from the patriarchate of Alexandria around 476. Photios mistakenly identified John with the priest John of Aegae because both were anti-Chalcedonian. John is cited by Theodore Lector.^[3]
