The date of the foundation of Cardiff is noted in the Latin text. There are some later memoranda as well.

The Romance of Charlemagne as written by Ieuan Ysgolhaig in 1336. The folios have been misarranged in the binding. This text seems to be the prototype of the version in Peniarth MS 5 (White Book of Rhydderch), Peniarth MS 10, and Jesus College Oxford MS 111 (Red Book of Hergest).
Two parts of the Romance of Charlemagne written in the thirteenth or fourteenth centuries. The text includes Charlemagne's expeditions to Jerusalem, Constantinople and Spain, and another fragment.
The Romance of Charlemagne written down by [?Gruffudd Ddu] in the mid 14th century; and a collection of poetry of Gruffudd ap yr Ynad Coch, Guto'r Glyn and others compiled in the 15th - 16th centuries.

The Welsh version of the Grail legend, translated from the French. One of the best preserved of medieval Welsh manuscripts. The text comprises: ‘Y keis’, derived from La Queste del Saint Graal (ff. 1-109 verso), printed from this manuscript in Ystoryaeu Seint Greal, ed. Thomas Jones (Cardiff, 1992), followed by the Welsh version of Perlesvaus (ff. 110-280 verso). The junction is recorded on f. 109 verso: ‘Ac uelly y teruyna y rann gyntaf or greal. nyt amgen nor keis. Bellach dywedadwy yỽ o rann gwalchmei. ac o anturyeu y milwyr ual y kyfaruu ac ỽynt’. The only lacuna in the text is in quire 18 (see collation). The text of both parts is printed in Y Seint Greal: Selections from the Hengwrt MSS, ed. Robert Williams (London, 1876). All written in the hand of Hywel Fychan ap Hywel Goch, no doubt for his patron, Hopcyn ap Tomas, probably earlier than Jesus College Oxford, MS 111 (datable post-1382), since the awdl by Dafydd y Coed in that book refers to Hopcyn’s book of the Greal.
