Great to hear poet Twm Morys on today's Sunday afternoon poetry slot on Radio 4 today. His programme explored and explained the intricate art of Cynghanedd in Welsh poetry and its origins as far back as the sixth century. Basically Cynghanedd refers to the complex patterns of rhyme and alliteration in various poetic forms in Welsh literature. Mererid Hopwood was one of the speakers - in 2001 she became the first woman poet to win the Bardic Chair at the National Eisteddfod (after all those centuries!). Both Dylan Thomas and Gerard Manley Hopkins used the techniques of Cynghanedd in their work.
A fascinating programme - you can catch it on BBC Radio 4 next Saturday night at 11.30pm or listen again on the BBC website.
