The Taliesin Sourcebook by Frank Olding

The main aim of this book is to present modern, reliable translations of all the medieval poems assigned to or concerning Taliesin together with all three variant versions of the Early Modern prose tales known variously as Ystoria Taliesin (“The Story of Taliesin”) or Hanes Taliesin (“The History of Taliesin”). 

Translations of medieval court poems with a bearing on the development of the Taliesin persona are also included, returning to the poems their unity as works of art, rather than regarding them as texts to be deciphered and dissected.
