Born at Amida about 507, he was there ordained as a deacon in 529 by John of Tella at Zuqnin Monastery, but in 534 we find him in Palestine, and in 535 he passed to Constantinople. He returned to the east in later years of the 530s, where he witnessed the devastations of the great plague first hand. He travelled the region, going so far as Egypt, in order to collect stories for his collection of saints' lives, which he compiled in a book around the year 565. He was back in Amida at the start of the furious persecution directed against the Monophysites by Ephrem, Melkite Patriarch of Antioch, and Abraham, bishop of Amida c. 520-541. Around 540 he returned to Constantinople and made it his residence. In Constantinople he seems to have early won the notice of Justinian I, one of the main objects of whose policy was the consolidation of Eastern Christianity as a bulwark against the Zoroastrian power of Persia, through persecution of all the remaining pagans of the empire. John is said by Barhebraeus to have succeeded Anthimus as Monophysite bishop of Constantinople, but this is probably a mistake. In any case, he enjoyed the emperor's favor until the death of the latter in 565 and was entrusted with the administration of the entire revenues of the Monophysite Church. He was sent by Justinian on a mission for the conversion of such pagans as remained in Asia Minor in 542, and informs us that the number of those whom he baptized amounted to 70,000. He also built a large monastery at Tralles on the hills skirting the valley of the Meander, and more than one hundred other monasteries and churches, mostly on top of demolished pagan temples. Of the mission to the Nubians which he may have promoted, though he did not himself visit their country, an interesting account is given in the 4th book of the 3rd part of his History. He was ordained bishop of Ephesus for the anti-Chalcedonians in 558 by Jacob Baradaeus, although his title was largely nominal and he remained in Constantinople. In 546, he collaborated with the emperor during a persecution targeting pagans in Constantinople and its neighborhood. He carried out this task faithfully, torturing all suspected of the "wicked heathenish error", as John himself calls it, and finding much worship of the ancestral gods amongst the Empire's aristocracy. But his fortunes changed soon after the accession of Justin II. About 571 John III the Scholasticus, the orthodox or Chalcedonian patriarch, began a rigorous persecution of the Monophysite Church leaders, and John was among those who suffered most. He gives us a detailed account of his sufferings in prison, confiscation of his property, etc., in the third part of his History. The latest events recorded are of the date 588, and the author cannot have lived much longer; but of the circumstances of his death nothing is known.
Writings
John's main work was his Ecclesiastical History, which covered more than six centuries, from the time of Julius Caesar to 588, although John himself employs the Seleucid era. It was composed in three parts, each containing six books. The first part seems to have wholly perished. The second, which extended from Theodosius II to the 6th or 7th year of Justin II, was, according to F. Nau, reproduced in full or almost in full in John's own words in the third part of the Zuqnin Chronicle, which was until recently mistakenly attributed to the patriarch Dionysius Telmaharensis. Modern research has shown that it is more likely that large parts are missing. Of this second division of John's History, in which he may have incorporated the so-called Chronicle of Joshua the Stylite, considerable portions are found in the British Museum manuscripts Add. 14647 and 14650, and these have been published in the second volume of J. P. N. Land's Anecdota Syriaca. But the whole is more completely presented in the Vatican manuscript, which incorporates much of John's chronicle in a kolophon dated to the eighth century. and by Witold Witakowski, Pseudo-Dionysius of Tel-Mahre: Chronicle, Part III ). The third part of John's history, which is a detailed account of the ecclesiastical events which happened in 571-588, as well as of some earlier occurrences, survives in a fairly complete state in Add. 14640, a British Museum manuscript of the seventh century. It forms a contemporary record of great value to the historian. Its somewhat disordered state, the want of chronological arrangement, and the occasional repetition of accounts of the same events are due, as the author himself informs us, to the work being almost entirely composed during the times of his imprisonment in Constantinople. The same cause may account for the somewhat slovenly Syriac style. The writer claims to have treated his subject impartially, and though written from the narrow point of view of one to whom Miaphysite Orthodoxy was all-important, it is largely a faithful reproduction of events as they occurred. This third part was edited by William Cureton and E.W. Brooks, and was translated - sometimes paraphrase - into English by Robert Payne Smith, into German by J. M. Schonfelder and into Latin by Brooks. John's other known work was a series of Biographies of Eastern Saints, compiled about 565-7. These have been edited by Land in Anecdota Syriaca, ii. 1-288, and translated into Latin by Douwen and Land, and into English by Brooks. An estimate of John as an ecclesiastic and author was given by the Louis Duchesne in a memoir read before the five French Academies on October 25, 1892.
