Glamorgan] to Wiliam Prys [of Briton Ferry], 27 July 1596 (see TLLM, t. 79; and L. J. Hopkin James and T. C. Evans: Hen Gwndidau . . . (Bangor, 1910), p. 278), and a prose item with the superscription 'Llyma friddwyd Gronw ddy ap Einon ab Add'. The volume is in several hands but the greater part is in the hand of one scribe possibly the Glamorgan poet Giles or Sils ap Siôn whose 'cywyddau' feature in the text (see TLLM, tt. 76, 87-92; and IMCY, t. 121).

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.

A slightly imperfect manuscript consisting mainly of transcripts of Welsh strict- and free-metre poems including poems by, or attributed to, Tal Iesin, [Rhys Prichard, 'Yr Hen Ficer'], Sir Rice ab Richard, John Tydyr, Dauydd Llwyd, Morgan ap Howel, Llywelyn Siôn, Thomas Llywelyn, Ioroeth Fynglwyd, Sieiles ap Siôn a Gwas yr henaynt, Ffylib Emlun, Dafydd Nawmor, Siôn Phelib, Morys ap Howel, Lewys Morganw[g], Llewelyn ap Howell, Robert Leia, Siôn Kent, Gryffydd Llwyd ab Einon Lygwy, Rys ap Hari, Iolo Goch, Dafudd Ddu 'o Euas', Lewys Glyn Kothi, Gwillim ap Ieuan, Ievan Glyn Cothi, Iefan ap Rydderch ap Iefan Llwyd, Dauydd ap Mredydd Tudyr, Thomas Gryffudd, ? Thomas Llewelyn Dd. ap Hyw[e]l 'o Flaengwrach', Thomas Jones, Hopgin Thomas Phulib, Thomas ap Ieuan ap Rhys, and Siôn Lewys Gwyn. Also included are a transcript of the Welsh tale of the birth of Taliesin (ff. 1-4), a few medicinal recipes, and some seventeenth century financial memoranda. The greater part of the volume is written in a number of artificial or contrived copying hands, the scribe in some instances appearing to simulate a gothic script. The initial capitals of some of the poems have elaborate decorative detail sometimes incorporating the outlines of human figures or faces, the latter mostly grotesques. The volume has been attributed to a Glamorgan or Gwentian copyist of the first half of the seventeenth century (see TLLM, t. 44). If this dating is accepted stanzas such as those by Rhys Prichard probably have to be regarded as later insertions. There are marginal annotations in the hand of Edward Williams ('Iolo Morganwg').

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).

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.

Both volumes contain marginalia in the hand of Edward Williams.
