Nestorian Questions on the Administrration of the Eucharist, by Isho' Yabh IV

Isho'yabh IV was a schoolmaster of very high repute and later became the Catholicos of the Church of the East. He wrote tracts on liturgical matters in the first two decades of the eleventh in order to restore the traditions of his church. In Nestorian Questions of the Administration of the Eucharist, Willem Cornelis van Unnik gives a comprehensive research of the liturgical writings of Isho'yabh IV in the context of the 'Nestorian' liturgical tradition based on the manuscript tradition. After an analysis of the text, the author gives an annotated English translation of the text and a reproduction of the original Syriac text with a critical apparatus.
