This is an edition of a large number of fragments of Middle Persian and Parthian Manichaean hymns in the . M. Boyce in the register of her 1960 identified fragments of hymns 'to the Third Messenger' (group 44); 'Parthian hymns written in couplets, unclassified' (group 58) and 'Hymns, unclassified, including poems' (group 81). Though some of these fragments have been published in the meantime and others are very small, this yields more than 250 previously unpublished fragments, many of considerable size. The fragments are presented in diplomatic edition together with a transcription and translation into English. Since most of the hymns are abecedarian they are presented as far as possible in strophic form. An extensive introduction, notes, a complete glossary and facsimiles of joined fragments accompany the edition. Will interest: Students of Manichaeism; of Central Asian history and cultures; of comparative religion; of Iranian languages and literatures.
