Barhadbshabba Arbaya
Barḥadbshabba ʿArbaya (late 6th – early 7th  century) was a teacher, historian and biblical commentator of the Church of the East. A native of Beth ʿArbaye, Barḥadbshabba was the chief instructor ("bādūqā") at the School of Nisibis during the directorship of Ḥenana of Adiabene. He wrote the "History of the Holy Fathers Persecuted for the Sake of Truth", a history of the Church of the East from the beginning until the death of Abraham of Beth Rabban (569), the third director of Nisibis. It was probably written not long after 569. Its focus is on the 4th and 5th  centuries, making it an important source for the Arian controversy and the dispute between Cyril and Nestorius. It is the oldest extant history from the Church of the East. Although his perspective is that of an East Syrian, Barḥadbshabba made use of Greek sources. In the last chapters he outlines the history of the School of Nisibis and the School of Edessa. Besides his "History", Barḥadbshabba wrote commentaries on the "Gospel According to Mark" and the "Psalms". Only fragments of the former survive. According to ʿAbdishoʿ of Nisibis, writing in the 14th century, he also wrote "a book of treasures  in three parts, and disputes ("drāše") with all religions ("deḥlān") and their refutation ... and a cause of the followers [school] of Diodore." Barḥadbshabba ʿArbaya is possibly the same person as Barḥadbshabba of Ḥulwān.
