Although almost as little is known of the historical Arthur as of the historical Roland, both are heroes of important epic cycles. Leader probably of a small band of warriors, Arthur gradually became, in the epics, first general-in-chief, then king, and finally emperor of all Britain. It is conjectured that the Arthurian legends must have passed from South Wales into Cornwall, and thence into Armorica, "where it is probable the Round Table was invented." Enriched by new accretions from time to time, the Arthurian cycle finally included the legend of the Holy Grail, which must have originated in Provence and have been carried into Brittany by jongleurs or travelling minstrels.

It has been ascertained that the legend of Arthur was familiar among the Normans before Geoffrey of Monmouth wrote his books, and it certainly had an incalculable formative influence on European literature, much of which can be "traced back directly or indirectly to these legends." It was also a vehicle for that element which we call chivalry, which the church infused into it to fashion and mould the rude soldiers of feudal times into Christian knights, and, as it "expanded the imagination and incited the minds of men to inquiry beyond the conventional notions of things," it materially assisted in creating modern society.

After thus tracing the Celtic germs and influence in English literature, it becomes necessary to hark back to the time of the Teutonic invasions, since English thought and speech, manners and customs are all of Teutonic origin. The invaders brought with them an already formed language and literature, both of which were imposed upon the people. The only complete extant northern epic of Danish-English origin is Beowulf, of which a synopsis follows, and which was evidently sung by gleemen in the homes of the great chiefs. Apart from Beowulf, some remains of national epic poetry have come down to us in the fine fragments of Finnsburgh and Waldhere, another version of Walter of Aquitaine.

There are also the Legends of Havelock the Dane, of King Horn, of Beves of Hamdoun, and of Guy of Warwick, all four of which were later turned into popular prose romances. Intense patriotic feeling also gave birth to the Battle of Maldon, or Bryhtnoth's Death, an ancient poem, fortunately printed before it was destroyed by fire. This epic relates how the Viking Anlaf came to England with 93 ships, and, after harrying the coast, was defeated and slain in battle.

The earliest Christian poet in England, Caedmon, instead of singing of love or fighting, paraphrased the Scriptures, and depicted the creation in such eloquent lines that he is said to have inspired some of the passages in Milton's Paradise Lost. Chief among the religious poems ascribed to Caedmon, are Genesis, Exodus, and Daniel, but, although in general he strictly conforms with the Bible narrative, he prefixed to Genesis an account of the fall of the angels, and thus supplied Milton with the most picturesque feature of his theme.

Next come the epic poems of Cynewulf, Crist, Juliana, Elene, and Andreas, also written in alliterative verse. In Elene the poet gives us the legend of finding of the cross[20] by the empress Helena, dividing his poem into fourteen cantos or fitts.

It is in Gildas and Nennius' Historia Britonum that we find the first mention of the legendary colonization of Britain and Ireland by refugees from Troy, and of the exploits of Arthur and the prophesies of Merlin. This work, therefore, contains some of the "germs of fables which expanded into Geoffrey of Monmouth's History of Britain, which was written in Latin some time before 1147," although this historian claims to derive his information from an ancient British book of which no trace can be found.

There is, besides, a very curious yet important legend cycle, in regard to a letter sent from Heaven to teach the proper observation of Sunday. The text of this letter can be found in old English in Wulfstan's homilies. Besides sacred legends, others exist of a worldly nature, such as the supposed letter from Alexander to Aristotle, the Wonders of the East, and the Story of Apollonius of Tyre. The first two, of course, formed part of the great Alexander cycle, while the latter supplied the theme for Pericles of Tyre.

With the Norman Conquest, French became the literary language of England, and modern romance was born. Romance cycles on "the matter of France" or Legends of Charlemagne, and on "the matter of Britain" or Legends of Arthur, became popular, and Geoffrey of Monmouth freely made use of his imagination to fill up the early history of Britain, for his so-called history is in reality a prose romance, whence later writers drew themes for many a tale.

Walter Map, born on the border of Wales in 1137, is credited with the no longer extant Latin prose romance of Lancelot du Lac, which included the Quest of the Holy Grail and the Death of Arthur. Besides Wace's Brut, we have that of Layamon, and both poets not only explain how Britain's name is derived from Brut,—a member of Priam's family and refugee from Troy,—but go on to give the history of other early kings of Britain, including Arthur. They often touch the true epic note,—as in the wrestling match between Corineus and the giant,—use similes drawn from every-day life, and supply us with legends of King Lear and of Cymbeline.
