This volume presents texts in the Iranian languages, Middle Persian and Parthian, preserved in the Berlin Turfan Collection. These hymns are predominantly in Middle Persian. They were identified by M. Boyce in the registers of her Catalogue of the Iranian Manuscripts in Manichaean Scripts in the German Turfan Collection as Hymns in Honour of the Hierarchy and Installation Hymns, Hymns in Honour of Church Leaders and Patrons. Few of the fragments have been published, and mainly in editions dating back to the time of their discovery. New and updated readings, transliterations, translations into English, notes and commentaries are provided here for all the fragments identified by Boyce. The Introduction provides a description of the main features of the hymns to the Manichaean elect hierarchy, to the local hierarchies, and to the hierarchies of the Hearers, as well as of the installation hymns, and those in honour of high clerics and lay patrons. Reflections are provided on the use of cryptography in the Manichaean texts in Manichaean script, and about the learning habits inside scriptoria in Manichaean monasteries in Central Asia, the existence of which has long been suspected. The volume contains a complete glossary and bibliography, as well as facsimiles of joined fragments. This work may interest: Scholars and students of Manichaeism, of Iranian languages, literatures, and religions, of comparative religions, and of Central Asian history and cultures.
