Dafydd ap Gwilym is the most renowned and original of Wales' medieval poets, and is considered by many to be the greatest Welsh poet ever. His main topics were love and nature, and his poems express an individual response that combines mischievous humour and intense feeling. He was a poetic pioneer who pushed the boundaries of the Welsh language and the craft of Welsh poesy. In this volume the versions in modern Welsh and the notes are an essential aid to allow the reader to appreciate the rich poetry of the original texts.
