The Welsh Triads.—The next of the important Celtic remains is called The Welsh Triads, an early but progressive work of the Cymbric Celts. Some of the triads are of very early date, and others of a much later period. The work is said to have been compiled in its present form by Caradoc of Nantgarvan and Jevan Brecha, in the thirteenth century. It contains a record of "remarkable men and things which have been in the island of Britain, and of the events which befell the race of the Cymri from the age of ages," i.e. from the beginning. It has also numerous moral proverbs. It is arranged in triads, or sets of three.

As an example, we have one triad giving "The three of the race of the island of Britain: Hu Gadarn, (who first brought the race into Britain;) Prydain, (who first established regal government,) and Dynwal Moelmud, (who made a system of laws.)" Another triad presents "The three benevolent tribes of Britain: the Cymri, (who came with Hu Gadarn from Constantinople;) the Lolegrwys, (who came from the Loire,) and the Britons"

Then are mentioned the tribes that came with consent and under protection, viz., the Caledonians, the Gwyddelian race, and the men of Galedin, who came from the continent "when their country was drowned;" the last inhabited the Isle of Wight. Another mentions the three usurping tribes; the Coranied, the Gwydel-Fichti, (from Denmark,) and the Saxons. Although the compilation is so modern, most of the triads date from the sixth century.

The Mabinogion.—Next in order of importance of the Celtic remains must be mentioned the Mabinogion, or Tales for Youth, a series of romantic tales, illustrative of early British life, some of which have been translated from the Celtic into English. Among these the most elaborate is the Tale of Peredur, a regular Romance of Arthur, entirely Welsh in costume and character.

British Bards.—A controversy has been fiercely carried on respecting the authenticity of poems ascribed to Aneurin, Taliesin, Llywarch Hen, and Merdhin, or Merlin, four famous British bards of the fifth and sixth centuries, who give us the original stories respecting Arthur, representing him not as a "miraculous character," as the later histories do, but as a courageous warrior worthy of respect but not of wonder. The burden of the evidence, carefully collected and sifted by Sharon Turner,[5] seems to be in favor of the authenticity of these poems.

These works are fragmentary and legendary: they have given few elements to the English language, but they show us the condition and culture of the British mind in that period, and the nature of the people upon whom the Saxons imposed their yoke. "The general spirit [of the early British poetry] is much more Druidical than Christian,"[6] and in its mysterious and legendary nature, while it has been not without value as a historical representation of that early period, it has offered rare material for romantic poetry from that day to the present time. It is on this account especially that these works should be studied.

Gildas.—Among the writers who must be considered as belonging to the Celtic race, although they wrote in Latin, the most prominent is Gildas. He was the son of Caw, (Alcluyd, a British king,) who was also the father of the famous bard Aneurin. Many have supposed Gildas and Aneurin to be the same person, so vague are the accounts of both. If not, they were brothers. Gildas was a British bard, who, when converted to Christianity, became a Christian priest, and a missionary among his own people. He was born at Dumbarton in the middle of the sixth century, and was surnamed the Wise. His great work, the History of the Britons, is directly historical: his account extends from the first invasion of Britain down to his own time.

A true Celt, he is a violent enemy of the Roman conquerors first, and then of the Saxon invaders. He speaks of the latter as "the nefarious Saxons, of detestable name, hated alike by God and man; ... a band of devils breaking forth from the den of the barbarian lioness."

The history of Gildas, although not of much statistical value, sounds a clear Celtic note against all invaders, and displays in many parts characteristic outlines of the British people.

St. Columbanus.—St. Colm, or Columbanus, who was born in 521, was the founder and abbot of a monastery in Iona, one of the Hebrides, which is also called Icolmkill—the Isle of Colm's Cell. The Socrates of that retreat, he found his Plato in the person of a successor, St. Adamnan, whose "Vita Sancti Columbae" is an early work of curious historical importance. St. Adamnan became abbot in 679.
