The Shbitho d-Dayroye is a thirteenth-century anthology dedicated to the personal prayer of monks and nuns. The collection comprises the writings of great saints in the Syriac Orthodox tradition including Ephrem the Syrian, Abraham Qidun, John Chrysostom, Gregory of Nazianzus, Philoxenos, Basil the Great, and Isaac the Syrian. For each of the seven daily prayer times (morning, third hour, noon, ninth hour, evening, and night), there is a main prayer and a closing prayer. The present edition is the first translation to make the spiritual treasures of the original Syriac text available to readers in English.
