Gregory Bar Hebraeus (ܓܪܝܓܘܪܝܘܣ ܒܪ ܥܒܪܝܐ, b. 1226 - d. 30 July 1286), known by his Syriac ancestral surname as Bar Ebraya or Bar Ebroyo, in Arabic sources by his kunya Abu'l-Faraj, and his Latinized name Abulpharagius in the Latin West, was a Maphrian (regional primate) of the Syriac Orthodox Church from 1264 to 1286. He was a prominent writer, who created various works in the fields of Christian theology, philosophy, history, linguistics, and poetry. For his contributions to the development of Syriac literature, has been praised as one of the most learned and versatile writers among Syriac Orthodox Christians. In his numerous and elaborate treatises, he collected as much contemporary knowledge in theology, philosophy, science and history as was possible in 13th century Syria. Most of his works were written in Classical Syriac language. He also wrote some in Arabic, which was the common language in his day. It is not clear when Bar Hebraeus adopted the Christian name Gregory (ܓܪܝܓܘܪܝܘܣ Grigorios), but according to the Syriac Orthodox tradition of naming high priests, it may have occurred at the time of his consecration as bishop. Throughout his life, he was often referred to by the Syriac nickname Bar ʿEvrāyā (ܒܪ ܥܒܪܝܐ, which is pronounced and often transliterated as Bar Ebroyo in the Western Syriac Rite of the Syriac Orthodox Church, giving rise to the Latinised name Bar Hebraeus. It was previously thought that this name, which means "Son of the Hebrew", was a reference to his Jewish background. Modern scholarship has moved away from this affirmation, because it is not substantiated by other facts. The name may refer to the ancestral origin of his family from ʿEbrā, a village by the Euphrates near Malatya, the city in which he grew up. A few Syriac sources give Bar Hebraeus's full Arabic name as DIN (جمال الدين ابو الفرج غريغوريوس بن تاج الدين هارون بن توما الملطي). However, all references to this longer name are posthumous. The Syriac nickname Bar ʿEbrāyā is sometimes arabised as ibn al-ʿIbrī (ابن العبري). E. A.
