John of Nikiû

John of Nikiû was an Egyptian Coptic bishop of Nikiû (Pashati) in the Nile Delta and general administrator of the monasteries of Upper Egypt in 696. He is the author of a Chronicle extending from Adam to the end of the Muslim conquest of Egypt. John of Nikiû's Chronicle contains important historical details otherwise unknown.

According to the History of the Patriarchs by Severus, Bishop of Al-Ashmunyn (Heliopolis), John of Nikiû lived under the Patriarchs John III, Isaac, and Simeon. But when John of Nikiû disciplined a monk guilty of some moral offense so severely that the monk died ten days later, the Patriarch Simeon removed John from his office.

John of Nikiû's Chronicle was originally written mostly in Greek. Some of the name forms indicate that John may have also written the sections concerning Egypt in Coptic. The work survives only in a Ge'ez translation. made in 1602 of an Arabic translation of the original. Sections of the text are obviously corrupted with accidental omissions. Most notably, a passage covering thirty years (from 610 to 640) is missing.
