Those learned men are, therefore, mistaken, who suppose, that the Druids never committed any of their compositions to writing; when it is evident, that these and others of their productions have been conveyed down to us. Taliesin, as I have before hinted, informs us, that he was instructed by them in many of their mysteries, particularly in that of the μετεμψυχωσις, and in many other rudiments of their philosophy. And hence it is, that his works are more obscure than those of any other of the ancient bards. There is also a certain degree of obscurity in the very words and language of Taliesin; and the same may be observed of the compositions of Aneurin Gwawdrydd and other bards of the same age, a catalogue of whose works may be found in the learned Edward Llwyd’s Archæology, collected from the notes of William Maurice, Esq., of Cefn y Braich. But Mr. E. Llwyd never saw any of the poetical compositions of Taliesin, Aneurin, and other early bards, except those of Llywarch Hen, which he found in _Llyfr Coch o Hergest_: and the works of these ancient authors will afford us very material assistance, not only in the investigation of our ancient British language, but also in examining historical facts, and in tracing the origin of the various tribes, who inhabited this island during that early period. Taliesin, in a poem, of which the following is the title, “_Cerdd am Feibion Llyr ap Brychwel Powys_,” mentions three separate nations, who had taken possession of different parts of Britain, previous to his time, viz., _Gwyddyl_ (Celts or Gauls,) _Brython_, and _Romani_, (Romans.) Gwyddyl, a Brython, a Romani, A wna hon dyhedd, a dyfysci; Ac am derfyn Prydein, cain ei threfi.
