context_page_description: Metropolitanate of Adiabene was an East Syriac metropolitan province of the Church of the East between the 5th and 14th centuries, with more than fifteen known suffragan dioceses at different periods in its history. Although the name Hadyab normally connoted the region around Erbil and Mosul in present-day Iraq, the boundaries of the East Syriac metropolitan province went well beyond the Erbil and Mosul districts. Its known suffragan dioceses included Beth Bgash and Adarbaigan, well to the east of Adiabene proper.
context_section_description: Erbil, the chief town of Adiabene, lost much of its former importance with the growth of the city of Mosul, and during the reign of the patriarch Timothy I (780–823) the seat of the metropolitans of Adiabene was moved to Mosul.  The dioceses of Adiabene were governed by a 'metropolitan of Mosul and Erbil' for the next four and a half centuries.  Around 1200, Mosul and Erbil became separate metropolitan provinces.  The last known metropolitan of Mosul and Erbil was Tittos, who was appointed by Eliya III (1175–89).  Thereafter separate metropolitan bishops for Mosul and for Erbil are recorded in a fairly complete series from 1210 to 1318.

He was also one of three metropolitans who were present at the consecration of the patriarch Israel in 961.   According to ʿAmr and Sliba, he was also present at the consecration of the patriarch Mari on 10 April 987.   According to Mari, however, the diocese of Mosul was vacant at the end of the reign of the patriarch ʿAbdishoʿ I (968–86).

  The metropolitan Eliya, metropolitan of Mosul (Athor) when Elijah of Nisibis completed his Chronography in 1018/19, was originally bishop of Piroz Shabur and later metropolitan of Damascus.

  The bishop Yahballaha Ibn Abu Darah of Beth Nuhadra was consecrated metropolitan of Mosul by the patriarch Sabrishoʿ III shortly after his consecration in 1064, following the death of the metropolitan Gabriel of Mosul.
