His editor suggests the years 1410 to 1480 as, approximately, those of the poet's life. He was a supporter of the house of Lancaster throughout his life, but he wrote no cywydd to celebrate the victory of Henry Tudor in 1485 ; Roberts concludes therefrom that he did not live long enough to witness the final triumph of his party. By now a considerable number of works by contemporaries of Dafydd Nanmor have been published and it is, consequently, necessary to reconsider the question of years and times, particularly as the amount of material at our disposal increases. One is inclined to suggest somewhat later dates — 1420 to 1485 or 1490 .
Besides the masterly praise bestowed by him in cywydd and awdl on Rhys o'r — Tywyn , and also on his sons, Dafydd Nanmor was the faithful eulogist of Edmund and Jasper Tudor (qq.v.) ; he also composed a cywydd and an awdl to Henry Tudor when the latter was but a child. For the meaning of his awdl enghreifftiol see J. Morris-Jones , Cerdd Dafod , 363-4, 379-82. Dafydd Nanmor , Dafydd ab Edmwnd , Ieuan Deulwyn , Deio ap Ieuan Du , and Tudur Penllyn , all d. about the same time; this causes much trouble and some difference of opinion among editors. It is difficult to think of one year in which to bury them all together. At the present time the choice lies between c. 1485 and c. 1490 , it being remembered that the ‘circa’ is emphasized.
Dafydd Nanmor was fond of puzzles ( gorchestion ) or abstruse questions : he liked to weave poems in cynghanedd on astronomy, astrology, and weather signs , to achieve wonders through the medium of the bardic measures; he liked to write on grammar . He quotes four lines from a Latin stanza on the feast of S. Paul and converts these into four englynion . The discovery of his name, written by himself in a Latin manuscript of a work by Giraldus Cambrensis , now in the National Library of Wales ( N.L.W. MS. 3024 ), is interesting; see N.L.W. Jnl. , ii, 11, and see the illustration; on p. 130 the words ‘ Gwenn or dol ’ appear in decorative letters. It is difficult to refrain from quoting from his ‘ Cyffes ’ (confession) (p. 78) — ' Ni thorrais un llythyrenn / O bin ag ingk heb ennw Gwen .’ He imitated in Welsh one of the Latin ‘crosswords’ of the early ages (‘ Sator arepo tenet opera rotas ’). There is a ‘computus’ also, in Pen. MS. 52 , in the hand of the poet (see Pen. MS. 75 (229) ; R.W.M. , i, 403, 503, 783).
