Gregory Bar Hebraeus is one of the most important authors of the later Syriac tradition. Among his many writings are works about philosophy, theology, history and various spiritual works. The present work, known as the Book of the Dove, represents Gregory's instruction for beginning and continuing in the ascetic life. The Syriac tradition has a long history of asceticism, so Gregory had a deep tradition of resources from which he drew inspiration. However, this work is not simply a recapitulation of previous works; it is a succinct but thorough instruction for those who choose a life of monasticism. The volume includes an introduction by Philoxenos Yuhanon Dolabani and presents the Syriac text in vocalized Serto script.
