“ Of the Syriac Old Testament Jacob produced what Wright calls “a curious eclectic or patchwork text,” of which five volumes survive in Europe (Wright’s Catalogue 38) . It was “the last attempt at a revision of the Old Testament in the Monophysite Church.” Jacob was also the chief founder of the Syriac Massorah among the Monophysites, which produced such MSS. as the one (Vat. cliii.) described by Wiseman in Horae syriacae, part iii. (2) Jacob was the author both of commentaries and of scholia on the sacred books; of these specimens are given by Assemani and Wright. ”

“ An important historical work by Jacob—a Chronicle in continuation of that of Eusebius—has unfortunately perished all except a few leaves. Of these a full account is given in Wright’s Catalogue 1062. (7) Jacob’s fame among his countrymen rests most of all on his labours as a grammarian. In his letter to George, bishop of Sĕrūgh, on Syriac orthography (published by Phillips in London 1869, and by Martin in Paris the same year) he sets forth the importance of fidelity by scribes in the copying of minutiae of spelling. ”

“ Krehl in Atti del iv. congr. internaz. degli Orientalisti (Florence, 1880) , pp. 433 sqq. ↑ Pseudo-Dionysius of Tell-Mahrē says 677; but Athanasius was patriarch only 684–687. ↑ According to Merx (op. cit. p. 43) this may be the celebrated convent of Eusebius near Apamea. ”
