 By its very nature, most of the work of the traditional Welsh court poets kept their own personalities far from their poetry, the primary purpose of which was to sing the praises of their patrons.Dafydd's work, in contrast, is full of his own feelings and experiences, and he is a key figure in this transition from a primarily social poetic tradition into one in which the poet's own vision and art is given precedence.Although Dafydd wrote comparatively conventional praise poetry, he also wrote love poetry and poetry expressing a personal wonderment at nature; Dafydd's poetry on the latter subject in particular is largely without precedent in Welsh or European literature in terms of its depth and complexity.
