Ishoyahb V

Brief accounts of Ishoʿyahb's patriarchate are given in the Ecclesiastical Chronicle of the Jacobite writer Bar Hebraeus (floruit 1280) and in the ecclesiastical histories of the fourteenth-century Nestorian writers ʿAmr and Sliba.

The following account of Ishoʿyahb's patriarchate is given by Bar Hebraeus:

Then Ishoʿyahb, an old and chaste man from Balad, who had formerly been bishop of Hirta, was made catholicus, for he was chosen by a certain famous doctor named Abu Mansur, son of a wise scribe. He was consecrated on the second Sunday of the Dedication of the Church, in the year 542 [AD 1147], and after he had fulfilled his office for twenty-eight years, he died on the night of the second Sunday after Ascension, on the twenty-fifth day of iyyar [May], in the year 570 of the Arabs [AD 1174]. He was succeeded by Eliya III, known as Abu Halim.[1]
