Learned monk and author. He studied under Shemʿon Shanqlawi and was a monk of the famous monastery of Beth Qoqa in Adiabene ; his fame as a scholar was such that he attracted pupils also from the Syr. Orth. Church, among them Yaʿqub bar Shakko . He was the author of an important grammar (unpublished) and a number of verse works on philosophy and on liturgy. His theological compendium Zqorā mlaḥḥmā (‘Well-woven fabric’) exists in several mss. and is quoted in later E.-Syr. literature.
