The foregoing stanzas, as well as many others of the same description, are still extant is the above mentioned book, called Llyfr Coch o Hergest, and likewise in several MSS. in the libraries of Llanvorda near Oswestry, and Hengwrt near Dolgellau; and, on account of their having accidentally been discovered among the compositions of that ancient bard Llywarch Hen, Dr. Davies and Edw. Llwyd have hastily and inconsiderately pronounced them to be some of his productions; but the frequent recurrence of the oak, their favourite tree, and the dark allusions to the druidical rites and privileges, most evidently and convincingly, (in my opinion,) denote their origin to be from that source. But here it may be objected, that the Druids could not, (as Cæsar declares it was not their usual practice,) have committed these verses to writing. Granted it was so in his time; yet it is manifest from the poems of our celebrated bard Taliesin, that, in subsequent times, they did not strictly adhere to this resolution; for many of their pretended mysteries are divulged in his compositions. It is also evident, that, in these early ages, the Druids were not the only persons, who were thus cautious of revealing their secrets to the vulgar; but the Bards also endeavoured to conceal their poetical rules and metres, from the public; for their book of prosody, containing the intricacies of the art, is distinguished by the name of _Cyfrinach y Beirdd_, (i.e. The Secret of the Bards,) and they were strictly prohibited from explaining these, except to their own noviciate disciples, which continued to be their practice nearly to our own times. But, notwithstanding these strict prohibitions, it is well known, that the poetical compositions of the bards were publicly recited; and it is evident that, after the commencement of the Christian æra, the Druids were not so scrupulously cautious with respect to these rules of secrecy, which may be proved from some stanzas, which I have seen in an ancient MS., denominated _Englynion Duad_, probably from a bard or druid of that name. Some few of the lines I shall here subjoin, for the inspection of the reader. Bid gogor gan iâr, Bid gan lew drydar, Bid oval ar a’i câr; Bid tòn calon gan alar. These lines have been introduced into our Welsh proverbs; and the following remark is made on them at the end of Dr. Davies’s MS. copy. “Gwyl y rhagor y sydd rhwng y rhai hyn ar rhai sydd yn Llyfr Coch, a hen gopiau eraill; a gwybydd fod y gerdd hon yn hen iawn; gan fod cymmaint o ymrafael rhwng yr hen gopiau.” i.e. Advertat lector quàm variant inter se exemplar Hergestianum et alia exemplaria in hoc cantico, et sciat, hoc carmen ob differentias prædictas esse vetustissimum.
