Gregory Bar Hebraeus;
(1226 – 30 July 1286), also known by his Latin name Abulpharagius or Syriac name Mor Gregorios Bar Ebraya, was a maphrian-catholicos (Chief bishop of Persia) of the Syriac Orthodox Church in the 13th century. He is noted for his works concerning philosophy, poetry, language, history, and theology; he has been called “one of the most learned and versatile men from the Syriac Orthodox Church” (Dr. William Wright).
Bar Hebraeus collected in his numerous and elaborate treatises the results of such research in theology, philosophy, science and history as was in his time possible in Syria. Most of his works were written in Syriac. However he also wrote some in Arabic, which had become the common language in his day.
