This volume, Kleyn’s dissertation from Leiden, contains the life of John, bishop of Tella, who died in 538 in Antioch, written by Elias of Dara. Kleyn edited the Syriac text and supplied it with an introduction and Dutch translation.
In this study, H. G. Kleyn deals with the life and works of Jacob Baradaeus and the role he played in the “monophysite” church to the time of his death in 578, including a thorough outline of Jacob’s writings.
