A.D. 1226-1286.  Gregory Abul Faragius, commonly designated Abul-Farag, but properly Mar Gregorius Abul-Faraj also called Gregorius Bar-Hæbreus, was of the Armenian race, born A.D. 1226 at Malatia, or Melite a town near the western bank of the Euphrates in Lesser Asia.  His father Aaron was a physician.  Abul-Farag studied theology, philosophy and medicine, and passed the greater part of his life in Syria.  He adopted Christianity and rose successively to be Bishop of Guba, Bishop of Aleppo, and in 1266 Primate of all the Jacobite Christians in the East.  He was the author of a great number of works which he wrote in Arabic and Syriac, but the best known is his history of the dynasties, from the Hebrew Patriarchs to the Moghuls.  He died in A.D. 1286 at Meragba in Azerbijan.  Dr. Pococke published his History of the Dynasties in 1663 with a Latin translation and a supplement.
