'Beirdd yr Uchelwyr' in the fourteenth and fifteenth centuries are considered to be the pinnacle of the bardic tradition in Wales in the Middle Ages. This is the first attempt at giving a comprehensive look at the period's literature in all its aspects. Attention is given to masters of the cywydd, such as Dafydd ap Gwilym, Iolo Goch, Guto'r Glyn, Dafydd Nanmor & Lewys Glyn Cothi.
