ABRAMO di BĒTH RABBĀN. - Syriac doctor, who lived from 449 to 569. He was the director for about 60 years of the school of Nisibis, in which he succeeded (according to Mari, p. 39) the founder Narsai, whose disciple and relative he was, and whose name he adopted (the nickname Beth Rabbān also means "of the house of our master", i.e., of Narsai). Under him, the school experienced great development.
According to Barhadbābbā (end of the 6th cent.), in PO 4, 389 and 9, 628, his works are: commentaries on the prophets, on Eccl. Ios. and Iudc., as well as an epistle written by order of Justinian, in which he sets forth his Nestorian faith and answers doctrinal questions put to him by his enemies. But the catalog of Ebedesu (Assemani, Bibl. Orient., III, 71) attributes many others to him. The manuscript of Diarbekir, II, attributes to him liturgical hymns which would be his only writings that have come down to us. This manuscript is now at the Patriarchate of Mosul (Vosté, in Muséon, 50 [1937], p. 349).
