In this book, Bedjan publishes not only the Syriac texts of the works of Sahdona (also known by the Latinized form of his name, Martyrius), who flourished in the first half of the seventh century, but also several homilies of Jacob of Sarug. Sahdona’s major work is his Book of Perfection, one of the most significant texts for our knowledge of East Syrian monasticism. Following this, Bedjan gives five letters written by Sahdona to various monks, and the section on Sahdona concludes with a short collection of maxims on wisdom. From Jacob, Bedjan gives a letter on the incarnation, five homilies on Mary, three on the nativity, one on the ascension, one on virginity, and, finally, a homily on the Council of Nicea. This large volume, containing almost 900 pages of Syriac text, 750 of which contain texts appearing here for the first time, concludes with a series of fragments by Ephrem, Palladius, and Chrysostom pertaining to those who have died. Bedjan’s introduction (in French) touches on what is known of Sahdona’s life and briefly describes each work included in the book, together with mention of the manuscripts employed.
