A volume containing Welsh poetry in strict and free metre, including a poem dated 1627 (f. 280), in an unidentified hand of the early seventeenth century; the same hand also wrote NLW MS 6471B and Jesus College, Oxford MSS 139 and 140.
The scribe was copying from at least six different manuscripts, the beginnings and ends of which he usually indicates, e.g. 'dechre llyfyr Mr Iohn peers' (f. 1), 'dechre llyfyr arall (ff. 60 verso, 225 verso) and 'diwedd i llyfr yma' (ff. 135, 225 verso). Books begin on ff. 1, 60 verso, 105, 135 and 225 verso; the sixth book probably began in the gap resulting from the excision of leaves between ff. 245 and 246. Additions include a poem, dated 1630, written in a contemporary hand on ff. iii-iv; englynion on ff. iv verso, and on f. 176 verso, probably in the hand of Lowry Evans; verses in free metre in an early-nineteenth century hand tipped onto f. 305; and a subject index of contents of the volume when it was complete in a hand of the second half of the seventeenth century on ff. 306-310.
