{18a} There were two Myrddins, or Merlins, as they are wrongly written by the English, viz. Myrddin Emrys and Myrddin Wyllt; the last was a noted poet, and there is a poem of his extant, entitled Avallennau, or the Apple-trees. {18b} Aneurin Gwawdrydd Mychdeyrn Beirdd, i.e. Aneurin the monarch of Bards, was a celebrated poet of North Britain. His poem, the Gododin, upon the battle of Cattraeth, is extant; but by reason of its great antiquity, is not easily understood at this distance of time, being upwards of twelve hundred years old: however, it appears, from what is understood of it, to have been a very spirited performance. {18c} Craig Vreiddin, is a high hill in Montgomeryshire. {18d} I know not where this country is. {18e} Some lines are wanting in the original. {19a} Knocking, I suppose, is somewhere near Offa’s ditch. {19b} Porth Ysgewin is near Chepstow, in Monmouthshire or Glamorganshire. {19c} Taliesin Ben Beirdd, or the chief of Bards, flourished about the year 560, or thereabout, under Maelgwn Gwynedd king of Britain, called by Gildas Maglocunus. Many of Taliesin’s poems are extant, but on account of their great antiquity are very obscure, as the work of his contemporaries are. There is a great deal of the Druidical Cabbala intermixed in his works, especially about the transmigration of souls. {20a} Rheidol is the name of a large river in Cardiganshire, and Glasgrug, one of the palaces of the princes of South Wales, is very near it, about a measured mile from Aberystwith, and at present the property of the Rev. Mr. William Powel, of Nanteos. {20b} Lleision was one of the palaces of the princes of Powys, corruptly now called Llysin; and the park about it is called Llysin-park, the patrimony of Lord Powys. {21a} The battle of Llwyvein was fought by Urien Reged and his son Owain, against Ida king of the Northumbrians. It is celebrated by Taliesin in a poem, entitled Gwaith Argoed Llwyvein, i.e. the battle of Argoed Llwyvein. {21b} Eurgain, Northop in Flintshire, so called from Eurgain, the daughter of Maelgwn Gwynedd. {21c} Demetia. This expedition of Llewelyn-ap-Iorwerth was against the Flemings and Normans, of which there is an account in Powel’s History of Wales, p. 277, 278. {22a} Llan Huadain, the name of a place in Pembrokeshire. {22b} Cilgeran, the name of another place in the same county, near the river Teivi. {22c} Llywarch Hen, the son of Elidir Lydanwyn a nobleman of North Britain, and cousin german to Urien Reged king of Cumbria; he was a great warrior, and fought successful against the Saxons; but fortune at last favouring the Saxons, he was obliged in his old age to retire to Wales. He had twenty-four sons, who wore golden chains, and were all killed in battles against the Saxons. Llywarch Hen was a noted Bard, his works are extant, wherein he celebrates the noble feats of his sons, and bewails his misfortunes, and the troubles of old age, especially in distress.
