File Llanstephan MS 54 [RESTRICTED ACCESS]. - Poetry,

A manuscript containing poetry of Dafydd ap Gwilym, Rhys Fardd, Iolo Goch, Dafydd Llwyd ap Llewelyn ap Gruffudd (Dafydd Llwyd, Mathafarn) and others. Ff. 83-134 contain transcripts, mostly in a modernised orthography, of pp. 9-62, 70 (l. 13)-102 of the Black Book of Carmarthen. F. 134 has the following note: 'Tro oddiyma rhagot 17 o ddalennau ac yno y cei di ychwaneg wedi ei scrifennu allan or llyfr du : ac yn dechreu Marwnad Madawc mab Mredydd'; however, there is no trace left of the leaves containing the material to which reference is made. Ff. 237-267 verso are in the hand of William Maurice, as is the note on f. 137 - 'O Lyfr Phylib Wiliams or Dyffryn'. The poem at ff. 135-136 is attributed by the scribe to Dafydd ap Gwilym, yet on its reproduction at f. 137 it is attributed to Gruffudd Llwyd ap Dafydd ab Einion [Lygliw]); this work is attributed in most manuscripts to Dafydd ap Gwilym - wrongly, as most students of Dafydd ap Gwilym would say.
