A manuscript in two volumes containing a corpus of Welsh strict-metre verse consisting almost entirely of 'cywyddau', and a few Welsh prose items. The foliation of the 'text' (original f. 1 missing, original ff. 2-21 renumbered 1-20, a previously unnumbered folio between original ff. 21-2 now f. 21, ff. 22-623 as originally numbered with 75 twice and 265 and 577 missed out) is continuous, and the division into vol. I (ff. 1-300), now NLW MS 13061B, and vol. II (ff. 301-623), now NLW MS 13062B, occurs in the middle of a poem. Unnumbered leaves of later origin than those of the text have been inserted at the beginning and end of each volume. The manuscript, sometimes referred to as 'Y Byrdew Mawr', is in the hand of Thomas ab Ieuan of Tre'r-bryn, parish of Coychurch, co. Glamorgan, the scribe of NLW MSS 13063B, 13069B, and 13085B, and was probably transcribed in the last quarter of the seventeenth century, partly from the manuscripts of an earlier Glamorgan copyist, Llywelyn Siôn (see TLLM, tt. 95, 167-73, 218-19, 268; IM, tt. 87, 154, 264; and IMCY, tt. 81, 175). It was probably presented to Edward Williams ('Iolo Morganwg') by the copyist's grandson also named Thomas ab Ifan (see TLLM, tt. 170, 268). The contents include (revised foliation) :- 1 recto - verso, rules re interpreting the significance of dreams in relation to the phases of the moon (incomplete); 1 verso-8 recto, another set of rules (183) for interpreting dreams ('Deall braiddwydon herwydd Daniel broffwyd'); 8 recto-11 recto, a sequence of forty-eight 'englynion' entitled 'Englynion rhwng Arthur a Liflod i nai' (see The Bulletin of the Board of Celtic Studies, vol.

The unnumbered folios at the beginning of each volume contain a list of the contents of the volume giving, in the case of the poems, the name of the poet, in a hand bearing a strong resemblance to that of William Owen Pughe, and the title of the poem, in the hand of Edward Williams. The folios at the end of the first volume contain an index of the bards whose works appear in both volumes. This is possibly in the hand of Hugh Maurice, tanner and copyist. On one of the added folios at the end of the second volume is a poem to the Reverend John Jones, D.D., dean of [the cathedral church of] Bangor. Both volumes contain marginalia in the hand of Edward Williams.

An imperfect manuscript consisting of thirty folios of uniform size and two smaller leaves, with the two halves of ? the lower cover of an early nineteenth century periodical or part publication, which at one time seems to have served as a protective covering, bound in at the beginning. A considerable part of the original manuscript appears to have been lost as the volume was described by the Reverend John Williams ('Ab Ithel'), circa 1856, as containing 'about 100 pages' (see L. James: Hopkiniaid Morganwg . . . (Bangor, 1909), p. 91). The former protective cover bears the inscription 'Llyfr Llanfihangel Iorwerth. Cywyddau amrafaelion. Siôn Cent hyd Dafydd Hopcin o'r Coetty. Englynion Eiry Mynydd, &c.', in the hand of Edward Williams ('Iolo Morganwg'), and the contents consist of transcripts of Welsh verse mainly in strict metre. Dafydd Hopkin of Coety, co. Glamorgan is sometimes named as the copyist (see L. James: op. cit., p. 91; TLLM, tt. 229, 267; and IMCY, t. 139). The poems include 'cywyddau' and 'englynion' by Thomas Prys, Ieuan Tew Brydydd, Dafydd Hopkin (1734), Ieuan Brechfa, Lewis Morganwg, Iorwerth Fynglwyd, Dafydd ap Gwilym, Rys Dynfwal (sic), Rhys ab Morys, ?Mredydd ap Rees, Swrdwal Hen, Huw Dafydd Probert, Siôn Tudur, Owain Gwynedd, Gwilim ap Ieuan Hen, Dafydd ap Edmwnt, Daio Lliwiell, Ieuan Tew Brydydd Ifangc, Huw Lewis, Gruffydd ab Ifan ab Llewelyn Fychan, Wiliam Cynwal, Morus ab Hywel ab Tudur, Siôn Cent, Hywel ab D'd ab Ieuan ab Rhys, Llywelyn Goch, Gruffydd Dafydd Fychan, Ieuan ab Hywel Swrdwal, Bleddyn Fardd, and Dafydd Llwyd Fach, a series of pseudo- gnomic poems with each stanza commencing with the words 'Eira mynydd' some of which are attributed to Llywarch Hen and Mabclaf ab Llywarch, and poems attributed to Taliesin and Aneurin. There are marginal notes by Edward Williams and his son Taliesin Williams.
