The Arthurian cycle consists in a number of epics or romances about King Arthur, the knights of his Round Table, or the ladies of his court. The Anglo-Norman trouvères arranged these tales in graduated circles around their nucleus, the legend of the Holy Grail. Next in importance to this sacred theme, and forming the first circle, were the stories of Galahad and Percival who achieved the Holy Grail, of Launcelot and Elaine who were favored with partial glimpses of it, and of Bors who accompanied Galahad and Percival in their journey to Sarras. The second circle included the stories of Arthur and Guinevere, of Geraint and Enid, of Tristan and Isolde, of Pelleas and Ettarre, of Gareth and Lynette, of Gawain, and of Bedevere. The third and last circle dealt with the epics of Merlin and Vivien, Uther and Igerne, Gorlois, and Vortigern.
To give a complete outline of the adventures which befell all these knights and ladies in the course of seventeen epics and romances,—of which many versions exist, and to which each new poet added some episode,—would require far more space than any one volume would afford. A general outline will therefore be given of the two principal themes, the Quest of the Holy Grail and King Arthur and his Round Table, mentioning only the main features of the other epics as they impinge upon these two great centres.
Some of the greatest writers of the Arthurian cycle have been Gildas, Nennius, Geoffrey of Monmouth, Wace, Robert de Borron, Marie de France, Layamon, Chrestien de Troyes, Benoit de St. Maur, Gaucher, Manessier, Gerbert, Knot de Provence, Wolfram von Eschenbach, Gottfried von Strassburg, Hartmann von der Aue, Malory, Tennyson, Swinburne, Howard Pyle, Matthew Arnold, and Wagner. Still, almost every writer of note has had something to say on the subject, and thus the Arthuriana has become almost as voluminous as the Shakespeariana. The legend of Arthur, almost unknown before the twelfth century, so rapidly became popular all over Europe, that it was translated into every language and recited with endless variations at countless firesides.
Robert de Borron is said to be mainly responsible for the tale of Merlin, the real poet of that name having been a bard at the court, first of Ambrosius Aurelianus and then of King Arthur. The Merlin of the romances is reported to have owed his birth to the commerce of a fiend with an unconscious nun. A priest, convinced of the woman's purity of intention, baptized her child as soon as born, thus defeating the plots of Satan, who had hoped the son of a fiend would be able to outwit the plans of the Son of Man for human redemption. In early infancy, already, this Merlin showed his miraculous powers, for he testified in his mother's behalf when she was accused of incontinency.
Meantime Constance, King of England, had left three sons, the eldest of whom, Constantine, had entered a monastery, while the two others were too young to reign. Drawn from his retirement to wear a crown, Constantine proved incapable to maintain order, so his general, Vortigern, with the aid of the Saxon leaders Hengist and Horsa, usurped his throne. Some time after, wishing to construct an impregnable fortress on Salisbury Plain, Vortigern sent for a host of masons, who were dismayed to see the work they had done during the day destroyed every night.
On consulting an astrologer, Vortigern was directed to anoint the stones with the blood of a boy of five who had no human father. The only child corresponding to this description was Merlin, who saved himself from untimely death by telling the king that, if he dug down and drained the lake he would find, he would discover broad stones beneath which slept two dragons by day, although they fought so fiercely at night that they caused the tremendous earthquakes which shattered his walls. These directions were followed, the dragons were roused, and fought until the red one was slain and the two-headed white one disappeared. Asked to explain the meaning of these two dragons, Merlin—the uncanny child—declared the white dragon with two heads represented the two younger sons of King Constance, who were destined to drive Vortigern away. Having said this, Merlin disappeared, thus escaping the wrath of Vortigern, who wished to slay him.
Soon after, the young princes surprised and burned Vortigern in his palace, and thus recovered possession of their father's throne. Then, one of them dying, the other, assuming both their names, became Uther Pendragon, king of Britain. Such was his bravery that during his reign of seven years he became overlord of all the petty kings who had meantime taken possession of various parts of England. He was aided in this work by his prime-minister, Merlin, whose skill as a clairvoyant, magician, inventor, and artificer of all kinds of things—such as armor which nothing could damage, a magic mirror, round table, ring, and wonderful buildings—was of infinite service to his master and fired the imagination of all the poets.
There are various accounts of Arthur's birth; according to one, Uther fell in love with Gorlois' wife Igerne, who was already mother of three daughters. Thanks to Merlin's magic arts, Uther was able to visit Igerne in the guise of her husband, and thus begot a son, who was entrusted to Merlin's care as soon as born. Another legend declares that, after Gorlois' death, Uther Pendragon married Igerne, and that Arthur was their lawful child. Feeling he was about to die, and fearing lest his infant son should be made away with by the lords he had compelled to obedience, Uther Pendragon bade Merlin hide Arthur until he was old enough to reign over Britain. Merlin therefore secretly bore the babe, as soon as born, to Sir Ector, who brought Arthur up in the belief he was the younger brother of his only son, Sir Kay.
Arthur had just reached eighteen when the Archbishop of Canterbury besought Merlin to select an overlord who would reduce the other kings to obedience, and thus restore peace, law, and order in Britain. Thereupon Merlin promised him a king would soon appear whose rights none would be able to dispute. Shortly after, on coming out of the cathedral one feast-day, the archbishop saw a huge block of stone, in which was imbedded an anvil, through which was thrust a beautiful sword. This weapon, moreover, bore an inscription, stating that he who pulled it out and thrust it back would be the rightful heir to the throne.
Meantime a tournament had been proclaimed, and Sir Kay, having broken his sword while fighting, bade his brother Arthur get him another immediately. Unable to find any weapon in their tent, Arthur ran to the anvil, pulled out the sword, and gave it to Sir Kay. Seeing it in his son's hand, Sir Ector inquired how it had been obtained, and insisted upon Arthur's thrusting it back and taking it out repeatedly, before he would recognize him as his king. As none of the other lords could move the sword, and as Arthur repeatedly proved his claim to it on the great feast-days, he became overlord of all the petty kings. At Sir Ector's request he appointed Sir Kay as steward of his palace, and, thanks to the help of Merlin and of his brave knights, soon subdued the rebels, and became not only master of all England, but, if we are to believe the later romances, a sort of English Alexander, who, after crossing the Alps, became Emperor of the World!
