Dangos 19 canlyniad

A seventeenth century manuscript consisting of eighty-three folios containing transcripts of Welsh strict-metre verse, being almost entirely 'cywyddau' and 'englynion'. The poems were transcribed by Thomas ab Ieuan, the copyist of NLW MSS 13061-13062B, 13669B,13085B, in 1684 (see note in the scribe's own hand on f. 80 verso - 'Llyma lyfr kywyddav Thomas Ievan o Dre'r brynn ag ef i hvnan ai ysgryvennoedd ef pan oedd oedran yn harglwydd ni iesu grist 1684'; see also TLLM, tt. 170-71). Included are 'englynion' by Robin Ddu, Huw Pennant, Rhys Nanmor and others, and possibly the transcriber himself (see TLLM, tt. 170-71); 'cywyddau' by Robin Ddu (7), Rhys Nanmor, Huw Pennant, Dafydd Gorlech (2), Iolo Goch (3), Dafydd Nannmor (2), Siôn Mawddwy, Bedo Brwynllys, Guto'r Glyn (3) and others; and an 'awdl' ('odl vraith') by Rhys Nanmor. There are marginal notes in the hand of Edward Williams ('Iolo Morganwg').

Monmouth, extracted mainly 'o Lyfrau Harri Siôn o Bont y Pwl a Llyfr ym Meddiant Rhys Thomas, Argraffydd o'r Bont Faen ym Morganwg', but only four 'englynion', presumably meant to be attributed to this poet, follow on p. 84.

In a note on the aforementioned 'title-page' (p. 199) Edward Williams claims to have transcribed this collection in 1799 from a manuscript in the possession of Siams Thomas of Maerdy Newydd, co. Glamorgan. Preceding and following the actual text of the collection are transcripts of a prefatory letter dated 1685 (pp. 201-06) and of the concluding note already referred to (p. 390) both of which are attributed to the Glamorgan scribe and copyist Thomas ab Iefan of Tre Bryn as compiler of the manuscript from which Edward Williams was allegedly copying (see TLLM, t. 172; IM, tt. 291-4). Pp. 391-477 contain a transcript of a collection, in alphabetical order, of over three thousand Welsh proverbs attributed to Cattwg Ddoeth ('Llyma Ddiarhebion Cattwg Ddoeth . . . sef yw hwnn Ail Lyfr y Gwyddfardd Cyvarwydd'). This collection, according to the aforementioned note at the end of the preceding section (p. 390) attributed to Thomas ab Iefan, had been compiled by the said Thomas from various sources and formed a continuation of the previous section. Edward Williams's claim with regard to the Siams Thomas volume is probably intended to apply to the contents of pp. 391-477 as well. The contents of pp. 199-390 have been published in The Myvyrian Archaiology of Wales . . ., vol. III (London, 1807), pp. 1-99.

A composite volume containing miscellaneous historical and literary material in the hand of Edward Williams ('Iolo Morganwg'). Pp. 24-36 contain a transcript of a version of the medieval Welsh Chronicle of the Princes associated with the name of the fifteenth century poet and genealogist Ieuan Brechfa with the title or superscription 'Brut y Tywysogion . . . a dynnwyd o Lyfrau Caradawc Llancarfan ac eraill o hen Lyfrau Cyfarwyddyd a ysgrifenodd Ieuan Brechfa'. The transcript was allegedly made by Edward Williams from a volume in the possession of Rhys Thomas, printer, of Cowbridge, and the text was published in The Myvyrian Archaiology of Wales, vol. II, 1801, pp. 470-565 (bottom section of pages). Pp. 37-135 contain one of the two known reputed transcripts by Edward Williams of the allegedly variant version of the aforesaid Welsh Chronicle of the Princes known as 'Brut Aberpergwm' or the 'Gwentian Brut'. The title or superscription reads 'Llyma Vrut y Tywysogion val y bu Ryfeloedd a Gweithredoedd enseiliaid a Dialeddau a Rhyfeddodau gwedi eu tynnu o'r hen gofion cadwedig a'u blynyddu'n drefnedig gan Garadawc Llancarfan', and the text was reputedly transcribed by [Edward Williams] 'Iorwerth Gwilym' in 1790 from one of the manuscripts of the Reverend Thomas Richards, curate of Llangrallo [co. Glamorgan], who, in turn, had reputedly copied the work in 1764 from a manuscript in the possession of George Wiliams of Aber Pergwm [co. Glamorgan] (see p. 135).

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.
