Jacob Bar-Salibi was a twelfth-century Syriac Orthodox bishop and highly productive scholar. Born in Melitene, he was originally known by his baptismal name, Jacob, but adopted the name Dionysius when he was consecrated as a bishop. He held several ecclesiastical positions, including serving as the bishop of Marash and Mabbug before being transferred to the metropolitan see of Amid in 1166. He remained in this role until his death in 1171, leaving behind a significant body of theological and liturgical literature.
