1911 Encyclopædia Britannica/Thomas of Margā
THOMAS OF MARGĀ, a Nestorian bishop and author of an important monastic history in Syriac, who flourished in the 9th century A.D. He was born early in the century, probably of Persian parents, in the region of Salakh to the north-east of Mosul. As a young man he became in 832 a monk of the famous Nestorian monastery of Beth 'Ābhē, which was situated at the confluence of the Great Zab with one of its tributaries, about 25 m. due east of Mosul. A few years later he was acting as secretary to Abraham, who had been abbot of Beth 'Ābhē, and was catholicus (patriarch) of the Nestorians from 837 to 850. At some date during these 13 years Thomas was promoted by Abraham to be bishop of Margā, a diocese in the same district as Beth 'Ābhē, and afterwards he was further advanced to be a metropolitan of Beth Garmai, a district farther to the south-east in the mountains which border the Tigris basin. It was during the period of his life at Beth 'Ābhē and his bishopric that he composed The Book of Governors, which is in the main a history of his own monastery, but includes lives of holy men in other parts of Mesopotamia and the regions east of the Tigris. The work was probably planned in imitation of the famous Paradise of Palladius, the history of Egyptian monasticism which had become well known to Syriac-speaking Christians in the version of 'Ănān-Īshō' (6th century).
The Book of Governors has been edited with an English translation and a copious introduction by E. W. Budge (2 vols., London, 1893), who claims that "it occupies a unique position in Syriac literature, and it fully deserves the veneration with which it has been and is still regarded by all classes of Nestorians to whom it is known." It gives a detailed history of the great monastery of Beth 'Ābhē during its three centuries of existence down to the author's time. It is full of interesting narratives of saintly men told in a naïve and candid spirit, and it throws much light on the history of Christianity in the Persian dominions. There is a later edition by P. Bedjan (Paris, 1901). (N. M.)
