Barhebraeus: Gregory Abū al-Faraj [Grīgōriyōs Bar `Ebrāyā; Grīgōriyōs Bar `Ebroyo; Ibn al-`Ibrī] Barhebraeus, a Syrian (or Syriac) Orthodox (“Jacobite”) prelate and polymath, is the foremost representative of the “Syriac Renaissance” of the 12th and 13th centuries. His name Barhebraeus is often linked to a Jewish ancestry, however more favorable is linking it to the village of `Ebrā on the Euphrates downstream of Malaṭya or Melitene. He was also closely associated with several members of the “Marāgha School” of astronomers and himself wrote several works dealing with various aspects of astronomy. [BEA, H. Takahashi]
