Contains the only full published English translation of the medieval Welsh bardic grammars and offers insight into the development of Welsh bardic and scholarly practices over two centuries. The medieval Welsh bardic grammars were composed and transmitted during a period of intense social and political change in Wales. These documents began their life as essentially vernacular artes poetriae . However, from the early fourteenth century to the end of the sixteenth, they were recopied and revised over and over by bards, bureaucrats, antiquarians, humanists, and the readers and reciters of poetry. Grammar and Poetry in Late Medieval and Early Modern Wales: The Transmission and Reception of the Welsh Bardic Grammars weaves a close textual analysis of these revisions into a broader consideration of the historical contexts that gave rise to each subsequent version. It grants English-speaking scholars who wish to work comparatively with Welsh material access to these texts for the first time. Based on extensive archival research, this book contains transcriptions and translations of a great deal of material that has not previously appeared in any publication.
