GWILYM DDU O ARFON ( fl. c. 1280-1320 ), poet ,

it is said that he lived in the place called Muriau Gwilym Ddu ( Enwogion Sir Gaernarfon ). A little of his work remains in manuscript and this includes two poems in praise of Sir Gruffydd Llwyd of Tregarnedd (q.v.) and written while Gruffydd was imprisoned in Rhuddlan castle , and an elegy to Trahaearn Brydydd ap Goronwy , or Trahaearn Brydydd Mawr — Jes. Coll. MS. 1 and ‘Llyfr Coch Hergest’ (1225, 1229) . An englyn on the coronation of king Edward II in 1307 is also attributed to him ( Enwogion Sir Gaernarfon ). It is stated that he was poet to prince Llywelyn ap Gruffydd ( Edward Jones , Relicks … ) but no examples of his poetry to Llywelyn have yet been found.
