Letters from H. Idris Bell, 8 Birchington Road, Crouch End, N. 8. to Ifor Williams Discusses the date of Aneirin and Taliesin's poems. The rhyme system however is a difficulty. Flower seems to think that it was not till about the 8th and 9th century that rhyme became general. It may be that the Welsh adopted it earlier than the Irish. 17/4/1945-9/6/1945
