Iolo Goch, o Goed Pantwn, yn Mhlwy Llan Nefydd yn Sir Ddinbych; y mae yno glwt o dir a elwir, y dydd heddyw, Gardd Iolo.—The tradition is fresh in the neighbourhood. I have read in the little book many good C. of D. ap Gwilym since I saw you, tho’ there are some very poor ones amongst them. What I had then read were looked over in haste, and it is impossible to form a right judgment of such things, without a careful perusal, especially when there are uncommon words or various readings to disturb the attention, as there are many in this book. I desire you’ll dash out of my Cywydd y Farn—_Tawdd y mellt greigiau gelltydd_, and insert these two in their stead—_Rhed filfil rhawd ufelfellt_, _Rhua drwy’r main rheieider mellt_—_See_ Edm. Pr. and Wm. Cynwal, Cyw. 29. I have had access to Llannerch library for three days successively, where there are a great many MSS., though few to your taste or mine.—English history, exploded philosophy, monkish theology, and such trash in abundance, written on fine vellum, in a most curious manner. Three good pedigree books, six or seven volumes of Welsh poetry, but for the most part very incorrect. Some of them are most shamefully mangled by the transcribers. I have borrowed one large quarto, transcribed about the conclusion of Queen Elizabeth’s reign, by an ignorant, slovenly fellow, who has murdered the orthography in a most barbarous manner. Yet I think it valuable, because, upon collating some parts of it with other copies, I found it in the general more genuine than the common run, notwithstanding the barbarity of the orthography. Where _tarw garw_ occur, this scribbler always robs the line of a syllable, which is the greatest injury he commits. I have transcribed _Duchan Gwyddelyn_, o waith Iolo. Marwnad Mad. ap Gr. Mailor, 1236, by Ein. Wan, Mar. Tywysog Llew. ap Gr. by Gwgon, Mar. Ow. Goch; a gânt Bleddyn Fardd; Cyw. merch da, o waith G. O.; Cyw. da i ofyn Cledd, o waith G. O.; Mar. Lleucu Llwyd, o waith I. Ll. G. M. H. Mar. Ll. G. M. H., o waith Iolo. There is at Llannerch a little old rag, consisting of about 20 pages accurately written, out of which I have transcribed a curious ode if not two. It begins thus: _Nid wyf ddihynwyf hoen_. _Kreirwy hoywdec am hudawdd mal Garwy_. After eight Englyns, there is a blank, without the author’s name, and below that begins either another ode of the same person’s, or a remainder of the foregoing, beginning thus: _Mireinwawr drefawr dra vo brad ymddwyn_, and subscribed Howel ap Eignion ai cant i Vevanwy vechan o Gastell Dinas Bran. After the last stanza is written _Mireinwawr drefawr_, with a dash, which makes me suppose they are two poems, though on the same subject; because it is common to conclude an ode with a repetition of the first stanza.—Quere, Whether the first of these is not the same with your Awdl Myfanwy? I cannot recollect, but I think it is longer than yours; it ends thus:
