An E.-Syr. student of the Cath. MarAba I (d. 552) associated with theSchool of Nisibis. He is probably not the same Toma of Edessa who is supposed to have taught Aba Greek as well as traveled with him to the West. Furthermore, he has been confused in the past with the W.-Syr.Tumo of Ḥarqel. His two extant treatises, one on the Epiphany and the other on the Nativity, are both examples of the E.-Syr. cause (ʿellta) genre, which focused primarily on the aetiology of E.-Syr. festival days. The former of these two texts remains only in ms. form. Along with these two texts,ʿAbdishoʿ attributes to him a refutation of astrology, ‘hortatory discourses’ (buyyāye), anti-heretical disputations, and a ‘letter onqāle’, that is, strophes with prefixed versicles that are chanted.
